Abstract
Solar photovoltaic (PV) is poised for tremendous growth in Africa over the next decade. The modularity
and cleanliness of solar PV allows for new generation to be installed much closer to final consumption, an
essential characteristic in a region where the grid is often saturated or non-existent. The current prices
for PV systems makes their installation profitable, even for the sole purpose of offsetting the fuel expenses
of the diesel and oil generators that are widely used across the continent.
Is this an investable thesis? In this paper, we consider briefly four different business model to harness the
value created by solar PV expansion across Africa, and assess their attractiveness in three very different
countries: South Africa, Kenya and Nigeria. We then proceed to take a deeper look at the best investment
opportunity we encountered during our research: an equity investment in a 100 MW solar project in
Nigeria. Finally, we describe the strategies used by the project developer to minimize risks and estimate
the profitability of this investment under a baseline scenario, as well as the potential downsides.

Power in Africa - A snapshot
Based on our research into the drivers below, we believe that solar photovoltaic (PV) power generation
will see tremendous growth in Sub-Saharan Africa (SSA) over the next five years. Further, we think that
there are attractive opportunities within the industry where private equity investments could earn
attractive, risk-adjusted returns. Below are the main drivers that build the investment case, followed by
our thoughts on where investments are possible.
SSA power consumption lags far behind every global average and will increase with time.
Currently, power consumption in SSA at 124 kWh per capita per year, is only a tenth of that found
elsewhere in the developing world, barely enough to power one 100-watt light bulb per person
for three hours a day)1. As the middle class in Africa grows, we expect they will use more
electricity and put upward pressure on the demand for electricity on the continent.
SSA power is expensive relative to other developing regions. Currently, the average effective
electricity tariff in Africa is USD $0.14 per kWh but ranges as high as $0.20 and $0.30 in many
countries both of which are many times more expensive than $0.04 per kWh paid in South Asia2.
This means that there is an opportunity for cheaper forms of electricity generation to play a role.
Diesel power generation is prevalent, expensive, and likely to become still more so. Africa still
generates a significant portion of its consumption from diesel generation with a fuel cost of over
$0.30 per kWh.
Solar productions costs are low and declining. LCOE3 for solar PV is near $0.07 per kWh in
California for utility scale projects4 and $0.12 per kWh for commercial projects. Given
infrastructure challenges, Africa may have higher costs but it also has significantly more sunshine
(25% more than Germany) and is one of the most appropriate places for solar power generation.
African governments are interested in solar. Significant interest has been demonstrated by
African governments and solar friendly policies and procurement programs have already been
implemented. For example, the South African government committed to procure up to 1.4 GW of
solar PV capacity5 and already signed contract for about 1 GW6.
Given the factors listed above, we believe that the demand for solar power could be dramatic and
represents potential for attractive, risk adjusted returns. However, there are many ways to be involved
in the industry and some are more appropriate than others.

Business models How do you invest?
Initial research also demonstrated that African countries have widely dissimilar energy markets. We
quickly became convinced that having the right business models for a given country was the most
important step towards capturing this growth opportunity and producing the outsized returns we are
aiming for. To this end we short listed five different business models for evaluation.
In the following section we will go over some of the types of business models that would profit from strong
PV penetration. This is meant to be a short overview of their characteristics and risk / reward profile and
then we will focus our efforts and dive deeper into the country and business model combination that is
the most attractive.
IPPs Residential & Commercial
IPP stands for Independent Power Producers. Some IPPs build large power plants, but others invest in
distributed systems located on clients premises, retaining ownership of the generating asset. The
revenues come from long term off-take agreements signed with the customers. This is similar to the
business model of Solar City for commercial projects in the USA.
Given the very high retail rates for industrial customers, there is a strong demand for behind the meter
power production. For example, when we interviewed Mauro Ometto, Business Development Manager
for Enel Green Power in Kenya, he reported having been approached multiple times by large electricity
consumers that wanted to have part of their consumption satisfied by on site generation operated by a
power company. An example of this type of company is SolaireDirect.
Pros Cons
Can gain upside from increasing
electricity rates over time
Better economics because competition is
with retail rates not wholesale rate
Opportunity to invest in power
generation with minimal government
interaction
Needs large access to capital, or
mechanism to enable third party finance
Customer will renegotiate if contract
price becomes higher than utility rates
Maintenance problematic (need to
access client premises)
Unless net metering exists, system size
limited by client consumption
Credit risk is high; repossessing assets in
case of default is expensive
Very few investments options. Solaire
Direct is the only one we found.

Micro-grid operators
In many rural parts of the world, grid electricity is simply not available. The populations of these areas
either pay a high price for electricity coming from diesel generator or completely lack access to electricity.
Some companies are stepping up, and building small micro-grids based on solar power and batteries. The
costs are high, but so is the willingness to pay (compares to kerosene spending on lamps and time spent
to charge cellular phones).
Rural electrification is quite a challenging space,
and some of the organizations trying to solve the
problem are actually non-profit (example: Egg
Energy). This being said, the winner of this race
will receive a rich prize as over 10 Bln $ a year is
currently being spent on Kerosene for lighting
purpose across Africa7. This number grows
exponentially as more appliances can be added
once a micro grid becomes available.
Director for Business Development of PowerGen
Re, Eve Meyer is very optimistic about the
prospects of her company, but acknowledge that
to attracting capital is proving to be challenge

Examples of for profit micro-grid operators are PowerGen Renewable, Standard Microgrid (Namibia) and
Devergy (Tanzania). Another interesting company (but a more VC-like investment) is PowerHive8 who is
developing an integrated micro-grid solution including pre-payment made through customers mobile
phone.
Pros Cons
Potential access to cheaper
development debt from DFI
Natural exit through an acquisition by
national utilities as grid expands
Client captive once grid is built
Client base sparse and with limited
financial resources
CAPEX intensive business
Rapid technological innovation might
create obsolescence of assets deployed
(battery integration, payment systems)

Equity investment in utility scale projects
Large solar projects have already gained access to project finance in some part of Africa but a significant
share of equity is still required. During an interview, the VP of Business Development for a global solar
project developer affirmed that South African commercial banks were willing to finance up to 70% for
such projects in South Africa and East Africa, as long as all the permitting was done and a PPA had been
signed. This has been confirmed by other interviewees as well.
Developers often have small balance sheets (unless they are also involved in other parts of the value chain)
and are unable or unwilling to shoulder all the equity risk for large projects. In the US, equity investors
would join in to enjoy the tax benefits (ITC, MARCs) that are too large for the projects to fully utilize on
their own, but such preferential tax treatment is not present in African countries. Solar has only recently
been cost competitive with diesel generation, and investors are not yet familiar enough with the
technology to finance large scale deployment across Africa, with the exception of South Africa where the
auction for solar projects has attracted a large number of international buyers.
The major risk for such long term investments is a PPA renegotiation during the plant life (30+ years). This
risk is obviously higher when there is excess availability of cheaper electricity sources. For example, one
interviewees warned about the possible availability of cheap gas (~4$/mmbtu) in East Africa over the next
5 to 10 years due to the gigantic offshore recently identified near Mozambique9.
Pros Cons
Attractive return on equity investment
attractive (except in South Africa)
Potential for exits by selling assets to
infrastructure funds once the plant is up
and running
Developers with worldwide experience
and reputation, with capability to deliver
performing plants
No risk linked to execution or
management once project is completed
Returns are expected to come down as
capital providers across the board are
becoming more comfortable with solar
and Africa. Equity returns in South Africa
already weak due to structured tender
process
Highly dependent on the national utility
for payments
PPA renegotiation a large risk (especially
when more expansive than newer power
sources)

Diesel hybridization
We believe there is an opportunity to purchase companies running large diesel generator fleets
(either for telecoms or micro-grids) and have them install solar panels to offset part of their diesel
consumption.
Figure 2. Levelized cost of solar PV compared with Levelized cost of Diesel generation and fuel cost, $/MWh
Source: Lazard 2013
As we can see on Figure 2, the difference between the fuel cost and LOCE (Levelized Cost of Electricity)
for diesel generation is very small. This is because diesel generators are inexpensive, but fuel costs are
very high at over $0.30 per Kwh.
Because fixed costs are so low for diesel generation, a diminution of the capacity factor10 does not have a
strong impact on the LOCE of diesel: a reduction of the capacity factor from 80% to 30% only increases
the LOCE of a diesel generator by approximately 7%. Co-locating solar PV generators would offset a
significant portion of the fuel expenses, replacing a fuel cost of ~0.30 $/kWh by an LOCE of ~0.15$/kWh.
Assuming the power is sold at 0.40 $/KWh, this represents an opportunity to quadruple EBITDA for the
operating company. Thika Power Limited is an example in this industry.
Pros Cons
Straightforward path to improve
economics of existing business
Diesel and oil power generation
currently on the rise in many African
countries.
Existing customer base and sales
agreements at high prices
Control stake with hands on
investment approach required to
change the business model
Future grid expansion puts a risk on
profitability
Additional capital requirements after
acquisition to install PV panels
Availability of suitable land near
existing facilities might prove an issue

Country Overviews
Kenya
GDP growth and distribution:
Kenya has a broad based economy, which reduces its vulnerability to external shocks and provides basis
for resilient growth. Rapid economic growth in other East African countries is expected to spur demand
for Kenyan goods and services. The GDP is expected to grow 5.6% in 2014 and 5.7% in 2015, helped with
relatively cheap credit and improving global conditions. GDP growth is expected to remain strong in the
following years. The main drivers of growth will be private consumption and investments, especially in
infrastructure. Despite the new investment, the fast growth is expected to highlight transport and power
bottlenecks.
Currency: Inflation and foreign exchange rates
Average inflation fell to 5.7% in 2013. Kenya is expected to adopt more rigid inflation targeting policy in
the coming years and inflation is expected to be 6.3% in 2014 and 5.8% in 2015. Two main determinants
of inflation are weather and global oil prices, and barring a serious disruption in them inflation should
remain in the range of 4.5-5.2% range until 2018. The weather determines inflation level due to its impact
on agriculture and hydroelectricity prices. As the monetary policy becomes more sophisticated and
competition in financial sector increases, the lending rate is expected to fall from 17.3% in 2013 to 11.3%
in 2018.
The shilling is currently valued 86.31 KSh/USD in 2013. The currency is expected to remain under pressure
from global monetary tightening, declining tea export earnings and local demand for foreign exchange
due to brisk economic growth. Barring major shocks, the exchange rate is expected to continue to
depreciate at a moderate pace and slide to 102.5 KSh/USD by 2018. The steady increase in exports,
tourism and remittances is expected to help narrowing the current account deficit from 9.3% of GDP in
2014 to 4.3% of GDP in 2018. However, dependence on short-term investment flows leaves the economy
vulnerable to external shocks.
Politics and regulation
Current President Uhuru Kenyattas clear victory in 2013 and subsequent peaceful transition of power
marked an improvement in political stability. Corruption, high taxes, over-regulation and weak
governance continue to be the main drag on the development of private sector and foreign investment.
However, the government has demonstrated commitment to business friendly economic policy. Foreign
investments usually receive the same treatment with the local investments and multinational companies
make up a large portion of Kenyas industrial sector. A handful of sectors, including power, is considered
strategic and remains in government control. However, there has been some liberalization and recently a
number of deals with independent power producers have been signed.

Tax regime
The main tax rate is 30% for locally incorporated companies and 37.5% for foreign firms. Companies newly
listed on Nairobi Stock Exchange pay a tax rate of 20% for 5 years. Dividends received by resident company
are usually exempt from tax. Non-residents pay 10% withholding tax they receive on dividends. VAT is
charged at 16% on most transactions.
Africa Factors
High levels of corruption and infrastructure problems discourage local and international investors. Ethnic
divisions is a potential source of instability in the country, ongoing conflict between different ethnic
groups can potentially boil over into violence especially during the election period. Civil wars in
neighboring Somalia and South Sudan are another main source of security risk and regional instability.
Climate is another risk factor for Kenyan economy - poor rain would hurt agriculture production, trigger
high inflation and strain balance of payments position.
Energy Supply11
Figure 3: Electricity Generation in Kenya, actual and forecasted
Source: BMI, World Bank
Electricity costs are quite high in Kenya, ranging from $0.20 to $0.24 per kWh12 and can vary by 20% to
25% year to year. Further, given the reliance on hydropower, energy costs are dependent on variable
rainfall. In January 2014, Kenya's government announced very ambitious plans the power sector, aimed
at grid extension, geothermal generation and solar power (1.2 Bln$ for solar alone, with the government
to providing 50% of the cost).

South Africa
GDP growth and distribution
South Africa is the largest and most advanced economy in Africa. It is an open economy exposed to global
developments and trends. The economy grew 1.9% in 2013 and is expected to grow by 2.5% in 2014 and
slightly accelerate in 2015-17. The main drivers for growth will be consumption and investments.
Currency: Inflation and foreign exchange rates
Consumer price inflation was 5.8% in 2013 and is expected to be 5.6% in 2014. The main driver of inflation
is sharp depreciation of rand which pushes up the import costs. Rises in electricity tariffs, wage increases
and currency depreciation will continue to exert upward pressure on inflation, however the inflation is
expected to remain under check within the central banks 3-6% target range in the coming years.
The average exchange rate was 9.64 R/USD in 2013, but weakened to 10.88 R/USD in January 2014.
Barring any exogenous shocks and drastic negative policy changes, rand is expected to slightly rebound
after the elections in April and later resume the tendency of gradual depreciation and hit 11.00 R/USD
range by 2018.
Politics and regulation
South Africa enjoys relatively strong and independent institutions. Even though African National Congress
has recently weakened, it is still dominant and this ensures political stability and policy continuity. The
ruling ANC is expected to win the elections in May, and President Jacob Zuma to serve a second five year
term.
South Africa also has an effective legal system that enforces contracts and regulations are usually
effectively implemented. Property rights are well protected and foreign investors do not have any
restriction for property ownership. There are no controls over the repatriation of income and capital gains
by foreign citizens. South Africa is one of the least corrupt countries in Africa, even though its profile has
slightly deteriorated in the recent years. The main threat to long term stability is big divide in the society
due to inequality. Even though South Africa is the most developed country in Sub-Saharan Africa, poverty
is widespread. According to the UNDP, 42.9% of the population lives on less than 2 USD per day. With
dissatisfaction rising among poor black South Africans who form the majority of the population, sudden
disruptive events such as the escalation of industrial unrest that took place in 2013 remains a risk.
Tax regime
Foreign investments can benefit from 50% or 100% tax allowance if the investment is approved and
managed through Strategic Industrial Project Program. Standard corporate tax rate is 28%. The tax rate
for foreign companies operating through a branch or agency is 34%. A standard VAT rate is 14%. Capital
gains are tax free and dividends received by a South African company are tax exempt.
Africa Factors
Structural shortcomings will continue to hamper South Africas long-term economic growth. Years of
-
10
underinvestment in education has resulted in skills deficit, which is the main reason of structural
unemployment. High unionization increases cost of labor for foreign investors. High HIV/AIDS prevalence
and high crime rate are two other factors that decrease the countrys attractiveness for foreign investors.
Problems in the power sector could be another important deterring factor for foreign direct investments.
Power Supply13
Figure 4: Electricity Generation in South Africa, actual and forecasted
Source: BMI, World Bank
Currently, energy is relatively cheap in South Africa ($0.08 to $0.16 per kWh14). However, this rate can be
substantially higher as municipalities charge extra fees on top of the national utility (Eskom) rates. As a
result of years of underinvestment state utility company Eskom is unable to meet the increasing demand
for power.
South Africas also supplies a significant portion of the neighboring states needs. To continue supplying
other countries as well growing domestic demand, Eskom is planning aggressive investments in expanding
generation capacity through more coal-fired plants, nuclear plants, and renewables. Eskom, they will
need to borrow 3 Bln$ a year for up to five years to finance their expansion plans15.

Nigeria
GDP growth and distribution:
With a population of around 150 million, Nigeria is the most populous country in Africa. A centrally
located, oil-rich and pro-reform Nigeria can potentially reap huge advantage from increasing investor
interest in Africa. The average growth is expected to be 6.4% in 2014-15 and 7% in the following years if
the new government is able to concentrate on economic growth after 2015 election.
Oil production is going to increase only slightly, so the non-oil sector is expected to be the main driver of
economic growth. Weak and unreliable power supply has been one of the main factors hindering
development of local industries. So, improvement in local energy supplies after the recent privatization
program is expected to support growth in these sectors.
Currency: Inflation and foreign exchange rates
Due to strong government spending in the election period and high import demand inflation is expected
to remain high at around 10%. Central Bank pursued tight monetary policy in the recent years to control
inflation, so whether the new leadership of the Bank will have the strength to continue the same position
will be critical.
Exchange rate was 155.4 N/USD in 2013, it is expected to be 165 N/USD in 2014 and continue this slide to
190 N/USD by 2018. General downward trend in oil prices and increasing imports due to infrastructure
spending and consumer imports will decrease the current account surplus. Overall the current account
surplus as percentage of GDP is expected to narrow from 8.1% in 2014 to 6.8% in 2018.
Politics and regulation:
Nigeria has high risk of political instability and terrorism. Threats to political stability come from different
angles. The ruling PDP expects a major challenge in the upcoming presidential election in 2015. The ethnic
and regional differences can lead to defections in PDP coalition prior to the election and a close election
result can trigger an extended period of instability. At the same time, the risk of Islamic insurgency in the
North and militancy in the Nigerian Delta spreading to commercial centers can harm investors confidence
and hence countrys economic prospects. Overall stability is expected to continue, however it cannot be
overruled that an unfortunate chain of negative events can lead to a military coup or civil war in the
extreme case.
Tax regime
Foreign firms are allowed full ownership of companies operating in Nigeria, with the exception of the oil
sector. Nigeria has relatively low taxation, with VAT just 5% and main corporate tax rate at 30%. A 10%
tax is imposed on capital gains. Dividends and interest are both subject to a 10% withholding tax.

Africa Factors:
Long-time political instability, corruption, inadequate infrastructure and poor macroeconomic
management have been the main impediments for Nigerias growth. High oil revenues have not trickled
down to population, 90.8% of Nigerians are living on less than 2USD per day, creating conditions for civil
unrest. Militancy in the North and oil-rich Niger Delta region has risk of spreading to other parts of the
country and this would deteriorate the overall business environment.
Nigeria is one of the most corrupt countries in the world, which is a major constraint both for business
development and policy improvement in the country. Problems in the energy sector come on the top of
Nigerias infrastructure shortcomings. In a recent survey, 54% of manufacturers cited unreliable power as
the most binding constraint to efficient production.
Power sector
Figure 5: Electricity Generation in Nigeria, actual and forecasted
Source: BMI, World Bank
In 2011, Nigeria produced just 25 terawatt-hours, or about 150 kilowatt-hours per person, which is 32
times less than the per capita generation in South Africa.
Nigeria has long sold its power below cost, thus discouraging investment in the sector and compounding
chronic electricity shortages. The situation is changing and a major tariff review was introduced in 2012.
The increase was massive, ranging from 28% to 88%, from an average price of about 6 cts/kWh. But price
is not the issue, but availability is. More than half the population is without grid access, and even those
on the grid experience frequent outage. Most Nigerian actually resort to own generation through
expensive diesel generators, spending over 13 Bln$ a year on fuel.

Deep dive: Project investing in Nigeria
The project that captured our attention during our research was a 100 MW solar farm developed by
Nigeria Solar Capital Partners, a JV between GigaWatt Global (a worldwide project developer) and Industry
Capital (a real commercial real estate American Private Equity firm with about 1.5 Bln$ AuM). We
interviewed Joel Abrams, the Managing Director of Nigeria Solar Capital Partners.
Nigeria Solar Capital Partners is acting within the Framework of President Obama's Power for Africa
initiative. Their target investment is 1 Bln$, out of which 300 Mln$ of equity and the rest from project
finance. This is the equivalent of 400 MW of solar PV plant. They already have one project signed that is
being built in Rwanda.
Rationale of the investment
Industry Capital is concerned about their ability to continue to provide the solid cash generation in
American real estate that their LPs are requiring and are looking for alternatives. They partnered with
GigaWatt Global, and are financing the development costs (approximately 4 Mln$) for solar projects in
Nigeria. Nigeria Solar Capital Partners will retain a small portion of the equity for the first project, and
invite an infrastructure fund or another Equity firm to participate (According to them, around 10 funds
are considering this opportunity, among which Abraaj and MacQuarie). The objective is to showcase the
viability and profitability of such projects to their current LPs and to develop the next projects for
themselves.
The choice of Nigeria was very deliberate. Here are the main drivers behind this decision:
Thanks to large oil revenues government should be able to pay a long term contract
denominated in US$
Because is a large deficit in electricity generating capacity (40 GW today, getting worst as
country grows over 5% annually), and its drag on growth the government is willing offer
advantageous terms to attract investment
Electricity prices are very high. According to Nigeria Solar Capital Partners, in some
regions in Nigeria electricity costs 15 cts per kWh (where natural gas is available) but in
many others, the cost is closer to 40 cts per kWh, as diesel generator are required.
The capital market for large solar project is very early stage, and proprietary.
In South Africa, the auction process we mentioned earlier combined with low perceived political risk drove
the contract price for electricity to very low prices (during another interview, the Manager of Business
development for Enel Green Power in Kenya confirmed that their winning bid was only 10 cts per kWh),
whereas Nigeria Solar Capital Partners was able to negotiate a price well over 20 cts per kWh.

Dealing with risk
There were two reasons Nigeria Solar Capital Partners decided to invest in a greenfield project. Firstly,
attractive options to invest in solar energy assets in Nigeria are lacking. Secondly, Industry Capital was
unwilling to take on risks linked with an existing business in Nigeria, such as tax liabilities, property right,
corruption, potential pending law suits, etc. Their preference was to start on a clean sheet.
The PPA is the central agreement to any solar projects, and a sine qua non condition to obtaining project
finance. Because the Nigerian government keen to attract foreign investment in power generation, the
PPA terms are extremely favorable: a high price denominated in US Dollars and adjusted by inflation. A
major risk for any project is the renegotiation of the PPA if it becomes uncompetitive compared to other
electricity source. However, power systems are not as fast moving as consumer goods, and it seems
almost impossible to us that a surplus of installed capacity could appear over the next six years: the 40
GW of current deficit will take decades to be fully resolved. As long as there are no excess capacity in the
system, the risk of negotiating the PPA is somewhat limited. To further limit this risk, First Nigeria Solar
Capital Partners will subscribe to a breach of contract insurance, either through MIGA, Lloyd's, or as a
cheaper alternative, Sinasure (Chinese government sponsored insurance institution)20.
Because this is a new type of investments, banks were not comfortable to finance this project over a long
period of time, so all free cashflows after interest payments will go towards principal repayment.
Hopefully future projects will be able to derive more benefits from the interest tax shield by attracting
longer term debt. Because the economics are so attractive, the debt will be paid down in six years, a
duration the lenders are more comfortable with.
The CFO of Sunfunder (a crowdsourcing finance platform based in Tanzania), Dustin Kahler, warned us
about technical risks for a PV project in Africa. According to him, Chinese panel manufacturers tend to
send their lowest quality lots in Africa, leading to projects unable to operate at specification. Nigeria Solar
Capital Partners mitigates that risk by selecting a global EPC company that will also take care of the
operation and maintenance of the plant and provides a full guarantee on the performance. It remains
uncertain if this guarantee will take the form of a Letter of Credit or a Corporate Guarantee, as the EPC
contract is into its final negotiations phase, but the contractor will guarantee a performance ratio of 79%,
which is only slightly lower than average values for such projects (~82%).

Returns
We evaluated whether this project could generate the kind of returns expected by the LPs of a private
equity fund by building a model based on the information provided by Nigeria Solar Capital Partners, other
interviewees and our own research. Snapshot of the models is provided in the appendix. Here are the
inputs for the calculations:
Initial costs
$ per Watt
installed

Conclusion
To invest in the solar PV opportunity in Africa, we would consider three options:
A minority equity stake in an IPP in South Africa. While the sector is not extremely attractive with
the current low level of electricity retail rate, the planned increase in rates could provide a
significant upside if it were to materialize. The main challenge for this type investment is to find
the right company with the right management team to execute.
A majority stake in the operator of a diesel generator fleet in Nigeria, followed by additional
investments in solar panels to offset fuel consumption. This is a large opportunity as Nigerians
spend 13 Bln$ annually on diesel for power generation. It implies a significant change of business
model for the acquisition target and hence would require a very active participation from the
operations team of the investing fund.
An equity investment in a utility scale solar plant project in Nigeria. South Africa was not attractive
for this type of investment because the strong international participation in solar procurement
auctions resulted in low electricity prices and meager returns for investors. In Kenya, the potential
impact of recent gas finds on electricity prices, as well as concerns on exchange rates made us
uncomfortable about such a long term investment.
Ultimately, we selected the third option developed by Nigeria Solar Capital Partners. Their project offers
effective and convincing ways to mitigate the risks inherent to a utility scale solar project (PPA
renegotiation, technical failure) while offering attractive returns with an Internal Rate of Return of 27%
and Money on Money multiple of slightly over 2. According to our estimations, even if the PPA is
renegotiated, the investment remains profitable with a MoM multiple of 1.55 thanks the breach of
contract insurance.
It is highly improbable that this level of returns will be only available on the long term. Once a track record
for solar PV project in Nigeria will be established, profitability will go down as more investor will be willing
to provide capital. We consider this project to be an excellent investment opportunity, and advise our
investment committee to consider it.

Solar resource overview
There are two type of measure for the amount of light received: Global and Indirect.
Figure6. World global irradiance (left) and direct irradiance (right)
Source: http://meteonorm.com/
We can make two conclusions from these 2 maps:
Africa has some of the best global irradiance in the world.
Northern and southern Africa have very high direct irradiance.

As a rule of thumb, when operating temperatures are high and light more diffuse, a developer
should use thin films panels with a direct band gaps (CadTel or CIGS) for best results. Projects in equatorial
Africa will therefore perform better with thin films panels. This might prove a hindrance since most of the
worlds production capacity is for silicon based solar cells.
