Solar Without Upfront Cost in Uganda: Buy, Lease, or Pay per kWh?

On September 2, 2026, dfcu Bank and Sawa Energy launched "dfcu Go Green – Powered by Sawa Energy" in Nakasero. The model gives qualifying SMEs and corporates fully financed on-site solar PV and battery systems with zero upfront capital, while Sawa Energy finances, designs, builds, owns, operates and maintains each installation. Clients pay through a long-term pay-for-consumption arrangement or a fixed lease, usually over 10 to 25 years. The partnership advertises savings of 10–30% below the grid tariff. The launch is a useful entry point, but it is not the whole decision. For the details of that specific partnership, see our breakdown of the dfcu-Sawa Energy zero-upfront solar offer.

The three financing structures in plain English

Commercial solar financing in Uganda reduces to three paths, regardless of which provider is named in the contract. The differences are not mainly technical; they are about who owns the system, who carries the performance risk, and how the contract behaves five or ten years from now.

• Outright purchase (CAPEX): You buy the system, own it, and can claim import-duty and VAT exemptions on qualifying solar equipment. You carry performance, maintenance and degradation risk unless you contract that separately.
• Fixed lease: A third party owns and maintains the system. You pay a fixed monthly amount regardless of production. Budget certainty is the draw, but seasonal load changes can mean paying for electricity you do not consume.
• Pay-for-consumption (PPA): The provider owns the system. You pay only for electricity consumed at an agreed rate below the grid tariff, under a long-term contract that usually runs 15 to 25 years.

What the numbers look like before contract terms

For a Ugandan commercial customer, the baseline matters. The grid tariff is approximately UGX 546 per kWh, while diesel generation typically costs between UGX 1,200 and UGX 2,500 per kWh. A 100 kW commercial system with 200 kWh of storage often pays back in four to six years where downtime exceeds $50 an hour. That gap explains why zero-upfront models are attractive, but the real cost difference depends on the contract, not just the tariff. We compare the operating-cost case in more detail in solar vs diesel in Uganda.

Why buying outright can be cheaper over ten years

The least discussed advantage of ownership is tax. Under the 5th Schedule of the EAC Customs Management Act 2004, solar panels, deep-cycle batteries, DC inverters and DC charge controllers are exempt from import duty and VAT. In practice that can mean avoiding roughly 25 percent import duty and 18 percent VAT on qualifying equipment. The exemption belongs to the importer/owner; in a lease or PPA, it typically accrues to the lessor or provider. However, available guidance notes that these incentives can be applied inconsistently and refunds can be slow, so you should confirm the correct HS code classification with URA and request written confirmation before import. Non-solar balance-of-system items such as cabling, mounting structures and switchgear may still attract duty at 25 percent.

Leases and PPAs: zero upfront is a trade, not a gift

With a third-party owner, you trade ownership and long-term margin for immediate cash-flow relief. A fixed lease gives budget certainty but does not track production; a PPA ties payment to actual consumption, which helps if your load is seasonal. Under IFRS 16, most leases will sit on your balance sheet, so they are not invisible debt. The tax exemptions accrue to the owner, not to you. This is also a different decision from financing a vehicle fleet, which we explore in our note on dfcu Bank vehicle asset finance.

Six contract terms that quietly set the real price

• Escalator clause: a 2.9 percent annual escalator compounds to roughly double the contract rate by year 25. A low starting tariff with a high escalator can be worse than a higher fixed rate.
• Buyout at undiscounted future cash flows: if you sell the property or want out early, you may owe the present value of all remaining payments. On some systems that has been reported between $80,000 and $200,000 at year five.
• Assignment without consent: the provider may assign the contract to an affiliate, lender or portfolio buyer. Without controls, you can end up with a poorly capitalized counterparty.
• Decommissioning: who pays to remove the system at the end of the term? The contract should require the provider to decommission and restore the property, and larger systems may justify a decommissioning bond.
• Performance guarantee shortfalls: a strong PPA or lease should include a minimum performance standard and compensation if the system under-produces.
• Hidden fees: maintenance may be described as included but still exclude inverter replacement, battery degradation beyond a threshold, roof reinforcement or switchgear upgrades.

A low starting price per kilowatt-hour is not a good deal if the escalator, exit and assignment terms are stacked against you.

The battery lever most buyers do not use

Battery chemistry also changes the long-term arithmetic. Lithium iron phosphate cells can last 6,000 or more cycles, often ten years or longer, while lead-acid batteries may need replacement every two to three years. That affects both total cost and the provider's maintenance obligations. Separately, a peer-reviewed study of behind-the-meter battery storage for tariff arbitrage in Uganda found that second-life battery storage could pay back in as little as two years under the assumptions studied, while new battery systems remained uneconomical at then-current prices. If the PPA provider is using new batteries, that premium is embedded in the tariff you pay.

Choosing your path: buy, lease, or pay for consumption

The short version of the decision framework is below. It is a set of conditions, not a universal answer.

• Buy outright if you have the capital, can manage maintenance or contract it separately, want to capture the import-duty and VAT exemptions, and expect to stay in the building for ten or more years.
• Choose a fixed lease if you value budget certainty above maximum savings, your energy consumption is stable year-round, and you prefer not to manage operations and maintenance.
• Choose a PPA if you want to minimize upfront cost, your consumption varies seasonally, the advertised savings against grid are meaningful for your site, and you have negotiated the escalator, buyout and assignment clauses to your satisfaction.

In our advisory work, we often see the same pattern: the offer that looks cheapest on day one becomes the most expensive by year ten because the exit and escalation terms were ignored. A vendor-neutral review can be worth more than another sales pitch.
