Solar Panel Loans UK: How to Finance Your Solar Panel Installation in 2026
Solar panels are at the forefront of the green environment. Solar panel installations have significantly increased to deal with unprecedentedly high energy bills. Awareness about climate change is also one of the important contributing factors to fuel this movement. Solar panel installation required a large budget.
Solar panels with batteries are the cheapest way to generate electricity and reduce energy bills. Still, with an upfront cost of about £6,000, they are beyond the reach of millions of households. Low-cost loans for solar panel installations can save you over £200 every year on electricity, but these loans have yet to be rolled out. Since low-cost loans are not yet accessible, it does not mean that there are no other suitable financing options.
What are solar panel loans?
Solar panel loans can be secured or unsecured. They have been designed to make your house energy efficient. When you borrow a sum of money for the installation of solar panels, it is called a solar panel loan.
How do solar panel loans work?
Depending on the loan amount, the repayment term of these loans could be between 1 and 25 years. Loans to be paid between 1 and 5 years are unsecured, while loans for a longer period are called secured loans.
- The loan amount is decided based on your credit score and project requirements.
- Lenders take a couple of days to process your application.
- Once approved, you will start making payments in fixed instalments.
What types of loans can help you with solar panel installation?
As you know, government-backed schemes are not available yet; you have an option of financing a solar panel installation through direct lenders, banks and credit unions. Here are the types of loans that you can consider for the installation of solar panels.
- Personal loans
Personal loans are available from banks, direct lenders and credit unions. Banks and credit unions provide these loans only to borrowers with good credit. If your credit rating is substandard, you will have to borrow money from direct lenders. Credit unions accept applications from subprime borrowers, but their deals are not as flexible as those of direct lenders.
Personal loans are unsecured loans as they are not pledged against a personal asset. They allow you to borrow a lump sum that you pay back over an extended period of time in fixed instalments.
To be eligible for a personal loan:
- Try to have a good credit score
- Have a strong repayment capacity
Borrowers with subpar credit histories can also apply for these loans, but interest rates will likely be high.
The pros and cons of personal loans
- Interest rates and repayment terms will remain fixed and unchanged.
- Fixed instalments enable you to easily fit them into your budget.
- Unsecured personal loans for bad credit come with higher interest rates.
- Monthly payments will add pressure to your household budget.
Personal loans are generally ideal for those who have a decent credit report.
- Green energy loans
Green energy loans could be secured or unsecured, which have been designed to meet environment-friendly projects. You can use these loans for installing renewable energy systems, upgrading energy efficiency and purchasing an electronic appliance as long as it contributes positively to the environment. Solar loans, electric vehicle loans and green mortgages are all covered under the category of green energy loans.
Eligibility criteria for green energy loans vary by provider. Banks may follow stricter criteria than lenders and credit unions.
The pros and cons of green energy loans are as follows:
- Green energy loans are available at discounted rates. They are way cheaper than personal loans
- Repayment terms are flexible. Green mortgages come with a longer repayment plan.
- These loans are not widely available. You can obtain them from a few specialist lenders and credit unions.
They are ideal for those who are actually concerned about their environment and want lower interest rates.
- Home improvement loans
Home improvement loans are also personal loans. They are pledged as security only when the loan amount is large. It depends on the policy of a lender and your overall credit profile whether you will have to secure these loans against your house. These loans can be used for a wide range of home improvement projects, and the installation of solar panels is among them.
A home improvement loan for solar panels in the UK allows you to borrow a lump sum of money that you pay back over a fixed period of time at a fixed interest rate. If your credit score is decent, you will be able to qualify for lower interest rates. Lenders will restrict the loan amount if your credit score is not up to scratch.
The upsides and downsides of home improvement loans:
- They are widely available from lenders, banks and credit unions. You can research and choose the most affordable deal.
- It helps improve your credit score, provided you pay it back on time.
- Interest rates will be higher than those on green loans.
- If it is secured, you will lose your home if you fall behind on payments.
Home improvement loans are best for energy-efficiency improvements.
