Solar Panel Finance UK: Pay Monthly Solar & Battery Options

Solar Panel Finance UK: Pay Monthly Solar & Battery Options

Solar panel finance lets you spread the cost of a new solar installation with fixed monthly payments rather than paying everything upfront.

Thanks to soaring energy costs, the current payback period for solar energy is at its most favourable, driving a surge in households across the UK choosing to lessen their dependence on the National Grid and greedy energy suppliers.

Recent data from the MCS reveals that over 1 million households in the UK have already embraced solar panel installations.

At Heatable, we offer pay monthly solar finance for eligible homeowners across the UK, including options 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 and lender approval.

PS We offer MCS-certified solar panel installation nationwide. Simply answer these questions, get your fixed price and arrange your free design.

Can you get solar panels on finance in the UK?

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

Instead of paying for the full system in one go, you can spread the cost over an agreed term.

This can make solar more accessible, especially if you want to install a larger system or include battery storage.

How does solar panel finance work?

A solar finance plan allows you to borrow the cost of your installation and repay it in monthly installments over a fixed term.

The exact monthly cost depends on:

  • the total installation price

  • whether you pay a deposit

  • the loan term you choose

  • the APR offered by the lender

In most cases, a longer term reduces the monthly payment but increases the total amount repayable.

Do you need a deposit for solar finance?

No. If approved, you can finance your solar installation without a deposit.

You can also choose to pay a deposit of up to 50% if you want to reduce the loan amount and lower your monthly repayments.

How long can you spread the cost over?

Solar finance terms typically range from 36 to 120 months.

That gives you flexibility to balance:

  • lower monthly repayments over a longer term

  • lower total interest over a shorter term

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.

This can be useful if you want to store more of the electricity your panels generate and use it later in the day, rather than exporting it back to the grid.

Is 0% solar finance available?

Some providers advertise 0% solar finance or other promotional offers, but availability depends on the installer, lender, term length and current funding arrangements.

If you are comparing finance options, check:

  • whether the rate is fixed

  • whether a deposit is required

  • how long the promotional rate lasts

  • the total amount repayable over the full term

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.

PS Did you know that solar panels can be installed on garage roofs and that smart meters are recommended for use with domestic solar arrays.

FAQ's

Can you get solar panels on finance in the UK?

Yes. Many UK homeowners choose solar panel finance to spread the cost of installation through fixed monthly payments instead of paying the full amount upfront.

Do you need a deposit for solar panel finance?

Not always. If approved, you may be able to get solar finance with no deposit. You can also choose to pay a deposit, often up to 50%, to reduce the amount you borrow and lower your monthly repayments.

How long can you finance solar panels for?

Solar panel finance terms typically range from 36 to 120 months. Shorter terms usually mean higher monthly payments but less interest overall, while longer terms can reduce monthly costs but increase the total repayable amount.

Can you finance solar panels and battery storage together?

Yes. In many cases, you can finance a solar panel system and battery storage as part of the same installation package. This can make it easier to spread the cost of a more complete home energy setup.

Is 0% solar finance available?

Sometimes. Some installers offer 0% solar finance or other promotional finance options, but availability depends on the lender, the installer, the repayment term and current offers. Always check the APR, total repayable amount and any eligibility requirements before applying.

Is Heatable the lender?

No. Heatable is a credit broker, not a lender. Heatable can introduce customers to lenders on its panel, but does not lend money directly.

Can you make overpayments on solar finance?

Yes. Many solar finance agreements allow overpayments, which can help reduce the balance faster or lower the total amount of interest paid. Always check the terms of your agreement first.

Can solar panels pay for themselves while on finance?

Solar panels may help reduce your electricity bills while you are repaying the finance, but savings vary by property, system size, energy use, export rates and finance terms. They do not always fully cover the monthly repayment.

How quickly can solar panels be installed after finance approval?

Installation times vary depending on demand, roof type, survey requirements and installer availability. After finance approval and order confirmation, the next step is usually arranging a suitable installation date.
