The upfront cost of a solar system is the single biggest reason many Kenyan households and businesses delay switching from KPLC, even when the long-term savings are obvious.
The good news is that solar financing in Kenya has matured significantly, and there are now several realistic paths to going solar without paying the full cost in one lump sum.
On top of that, the tax treatment of solar equipment in Kenya remains genuinely favourable, which lowers the entry cost further than most people realise.
This guide walks through the main financing options available, how they compare, and the current VAT position on solar equipment as of 2026.
Pay As You Go Solar Financing
Pay as you go, commonly shortened to PAYG, has become one of the most popular ways for households to access solar in Kenya, particularly for smaller home systems.
How it works
Instead of paying the full system cost upfront, you make a smaller initial deposit followed by regular payments, often daily or weekly, similar to how mobile money airtime or utility tokens are purchased.
Once the total cost is paid off over the agreed period, typically ranging from one to three years, the system becomes fully owned by the customer.
Who it suits best
PAYG is particularly well suited to households that do not have access to a lump sum but can comfortably manage smaller, predictable payments spread over time.
It has been especially effective in reaching customers who were previously off-grid entirely, since it mirrors the pay-per-use pattern many households are already used to with mobile money.
What to check before signing up
Total cost over the full payment period compared to the upfront cash price, since PAYG plans typically cost more in total due to financing built into the payments What happens if you miss a payment, including whether the system gets remotely disabled?
Whether the system remains under warranty throughout the financing period What ownership looks like once payments are complete, and whether you receive documentation confirming the system is yours
PAYG providers in Kenya have built extensive networks reaching rural and peri-urban areas, which is a major reason solar adoption has grown so quickly outside major towns where bank financing is less accessible.
Bank Loans for Solar Financing
For larger systems, particularly commercial installations or full home systems with battery backup, bank financing is often a better fit than PAYG, mainly because of lower overall borrowing costs when structured correctly.
How it works
You apply for a loan specifically for solar installation, either through a dedicated green energy loan product or a standard asset finance facility.
Many Kenyan banks now offer solar-specific loan products with terms tailored to the expected savings the system generates, recognising that the monthly electricity savings can effectively cover the loan repayment.
Typical loan structures
Loan terms usually range from two to seven years, depending on the bank and system size.
Interest rates vary by institution, and some banks offer preferential rates for green energy loans compared to standard personal loans.
Collateral requirements differ, with some products using the solar equipment itself as security rather than requiring separate collateral.

Who it suits best
Bank loans work well for households or businesses with an existing banking relationship, a reasonably stable income, and a system large enough that the total interest cost is worth the lower per unit financing cost compared to PAYG.
Commercial and industrial customers installing larger systems almost always go this route, since the loan amounts involved are usually too large for consumer PAYG products.
What to check before applying
- Total interest cost over the full loan term, not just the monthly repayment figure.
- Whether the bank requires a professional system design and installer quote before approving the loan.
- Early repayment terms, in case you want to pay off the loan faster using electricity savings.
- Whether the loan is tied to a specific installer or panel brand, which can limit your choice of equipment.
Comparing PAYG and Bank Loans
Neither option is universally better, since the right choice depends on your specific situation.
PAYG generally works best for smaller residential systems, customers without a formal banking history, and anyone who values a low upfront deposit over minimising total cost.
Bank loans generally work best for larger systems, customers who already have a banking relationship, and anyone focused on minimising total financing cost over the life of the loan, since interest rates on structured bank loans are often lower than the effective financing cost built into PAYG payments.
Some households actually use a hybrid approach, starting with a smaller PAYG system to prove out the savings, then later taking a bank loan to expand capacity or add battery storage once they have a track record and more confidence in the numbers.
Outright Cash Purchase
It is worth mentioning the third option directly, since it remains the cheapest path overall for anyone who can afford it.
Paying cash upfront avoids financing costs entirely, meaning every shilling saved on electricity from day one goes straight toward your payback period rather than partially covering interest or financing fees.
For households or businesses with the capital available, this remains the most cost-efficient route, even though it requires the largest initial outlay.
VAT on Solar Equipment in Kenya
Here is a genuinely useful fact that affects the cost of every financing option above.
Solar panels, inverters, and related power generation equipment in Kenya are exempt from VAT and import duty under Sections 14(1)(e) and 15(n) of the VAT Act, a position that has held for years and continues to apply.
Solar batteries and lithium-ion batteries specifically went through a period of uncertainty in 2026, when the Finance Bill proposed reclassifying them from zero-rated to exempt status, a technical change that would have trapped input VAT in the supply chain and pushed retail prices higher.
Following pushback from lawmakers and industry, Parliament retained the zero-rated VAT status for solar and lithium-ion batteries, along with electric motorcycles, bicycles, and buses, when the Finance Bill was passed into law.
The practical takeaway for anyone financing solar today is that the equipment itself continues to benefit from favourable VAT treatment, keeping upfront system costs lower than they would be under standard 16 per cent VAT.
This tax treatment applies regardless of which financing route you choose, whether PAYG, a bank loan, or outright cash purchase, since it affects the underlying equipment price rather than the financing structure layered on top of it.
Given how often tax policy on green equipment gets revisited in Kenya, it is worth confirming the current VAT position with your installer or supplier at the time you buy, since pricing should already reflect whatever the applicable rate is on the day of purchase.
Choosing the Right Financing Path for You
Before committing to a financing option, it helps to answer a few honest questions about your situation.
Can you comfortably absorb a lump sum payment, or do you need the cost spread over time?
Is your system small enough for PAYG to make sense or large enough that bank financing becomes more cost-effective?
Do you have an existing relationship with a bank that offers solar-specific loan products? How long do you plan to stay in your current home or keep operating your current business location, since this affects how much of the long-term savings you will actually capture?
Whichever path you choose, the underlying economics of solar in Kenya remain strong, and the combination of falling equipment costs, expanding financing options, and continued favourable VAT treatment means the barrier to entry keeps getting lower even as electricity prices from the grid keep climbing.
