So Energy has introduced a 0% finance option for solar installations, allowing customers to spread the cost of the work rather than pay for it in one sum. The supplier set out the option in an article on the cost of solar panels published in December 20241.
The article gives no rate beyond the 0% figure, no repayment period, no minimum or maximum spend and no eligibility conditions. It does not say whether the finance applies to battery storage as well as panels, or whether it is limited to installations So Energy itself carries out. None of those details has been reported1.
The same article sets out the scale of a typical installation, saying that a residential system usually needs between 4 and 25 panels to cover a home's electricity use. It attributes the wide range to roof orientation, available sunlight hours, roof size and annual consumption, and says the company's solar team produces a plan for each property. It also notes that a battery storage system can be added so that generated electricity is stored for later use1.
On cost, the article says the total depends on how many panels are fitted and whether a battery is included, but it does not publish a price per panel, a typical installed cost or a worked example of monthly repayments under the 0% option. It says the quotation process asks for exact usage so that savings, payback period and panel numbers can be set out, and that a breakdown is provided at that stage1.
Why it matters for households
Solar is an upfront purchase that pays back over years, so how the cost is spread matters as much as the headline price. A 0% finance option removes interest from the borrowing, which means the amount repaid equals the amount quoted, provided the terms hold. What is not yet reported is the length of the agreement, whether a deposit is required, and what happens if a household moves home or ends the contract early. Those terms decide whether the offer is genuinely cost-free or carries charges elsewhere.
For a household weighing up finance for a home energy installation, the practical comparison is between paying upfront, borrowing at 0% and using an interest-free loan or finance scheme from elsewhere. A solar array with a battery reduces the amount of electricity bought from the grid and the exposure to future price changes, which is the energy independence element. The size of that benefit depends on the system fitted, the household's usage and how much of the generation is used at home rather than exported.
So Energy's own terms sit alongside its tariffs and company profile, and households comparing installers may also look at how other suppliers structure installation services and home energy installations. Quotes from more than one installer remain the usual way to test a price, as set out in getting quotes for a home energy installation.
What happens next
No end date for the 0% finance option, and no start date beyond the December 2024 article, has been reported1.
