Solar Panel Finance in the UK: Pay Monthly for Solar in 2026

For many homeowners, solar finance is the simplest way to spread the cost of installation rather than paying the full amount upfront. Depending on eligibility and lender approval, you can often pay monthly over a term of 36 to 120 months, with the option to put down no deposit or reduce borrowing by paying part upfront.

At Heatable, eligible homeowners can apply for pay monthly solar finance, including finance for solar panels with battery storage. You can choose a repayment term that suits your budget, make overpayments, and get a fixed solar quote before you apply.

Heatable is a credit broker, not a lender. Finance is subject to status, affordability checks and lender approval.

Can you get solar panels on finance in the UK?

Yes. Many UK homeowners choose to buy solar panels on finance to avoid the larger upfront cost of installation.

Instead of paying for the full system in one go, you spread the cost over fixed monthly repayments. This can make solar more accessible, especially if you want a larger system, premium panels, or battery storage included.

Solar finance is often used by homeowners who want to start saving on electricity sooner without paying the full installation cost on day one.

How does solar panel finance work?

Solar panel finance allows you to borrow the cost of your installation and repay it in monthly instalments over an agreed term.

Your monthly payment will usually depend on:

• the total installation cost

• whether you pay a deposit

• the repayment term you choose

• the APR offered by the lender

In simple terms, shorter terms usually mean higher monthly payments but less total interest, while longer terms usually mean lower monthly payments but more total interest over time.

That is the trade-off.

Do you need a deposit for solar finance?

Not always.

If approved, many homeowners can finance their solar installation without a deposit. You may also choose to pay a deposit of up to 50% if you want to reduce the amount borrowed and lower your monthly repayments.

A deposit can also reduce the total interest paid across the life of the agreement.

How long can you spread the cost over?

Solar finance terms typically range from 36 to 120 months.

That gives homeowners some flexibility depending on their budget and priorities.

A shorter term usually means:

• higher monthly payments

• less total interest

A longer term usually means:

• lower monthly payments

• more total interest overall

Neither is automatically better. It depends on whether you care more about monthly affordability or keeping the total repayable lower.

Can you finance solar panels and battery storage together?

Yes. In many cases, you can include battery storage in the finance agreement alongside your solar panel installation.

Is 0% solar finance available?

Sometimes, but not always.

Some providers promote 0% solar finance or limited-time finance offers, but availability depends on the installer, lender, loan term and current commercial arrangements.

If you are comparing solar finance options, check:

• whether the rate is fixed

• whether a deposit is required

• how long any promotional rate lasts

• the total amount repayable over the full term

• whether battery storage can be included

A 0% headline can sound brilliant, but the real comparison should always be the total cost, not just the monthly figure or the ad copy.

What affects your monthly solar payment?

Your monthly repayment will usually depend on five main factors:

1. System size

A larger solar array costs more and increases the amount financed.

2. Battery storage

Adding a battery usually increases the installation cost, but it may improve how much of your solar electricity you can use at home.

3. Deposit amount

Paying a deposit reduces the balance you need to borrow.

4. Loan term

Longer terms reduce monthly repayments but usually increase total interest paid.

5. APR

A lower APR generally reduces both monthly payments and total repayable cost.

Is financing solar panels worth it?

For some homeowners, yes.

Solar finance can make sense if:

• you want solar now without paying the full cost upfront

• the monthly payment fits comfortably within your budget

• you plan to stay in the property for several years

• you value spreading the cost over time

• you want to include battery storage without a large one-off spend

It may be less attractive if:

• you can afford to pay upfront and avoid finance costs

• the APR is high

• the total repayable amount materially weakens the long-term return

• you may move house in the near future

The right answer depends on your cash flow, how long you expect to stay in the property, and whether monthly affordability matters more than minimising total cost.

What should you check before taking solar finance?

Before agreeing to any solar finance plan, check:

• the APR

• the monthly repayment

• the total repayable amount

• whether the rate is fixed

• whether you can make overpayments

• whether there are settlement fees

• whether battery storage is included

• whether the quote includes scaffolding, installation and certification

This is where people get lazy and regret it later. The monthly payment is only part of the story.

Final word

If you are wondering whether you can get solar panels on finance in the UK, the answer is yes.

For many homeowners, finance is the most realistic route to getting solar installed without a large upfront payment.

The key is to compare the monthly payment, APR, term length, and total repayable amount properly, rather than getting hypnotised by one attractive number.

Used sensibly, solar finance can make a good system affordable. Used lazily, it can make a decent deal expensive.

Get the numbers first. Then decide.
