Explore your options for solar panel loans and make clean energy affordable today
With energy prices remaining unpredictable, more homeowners across the South East are turning to solar power for long term savings and energy independence. But one of the most common questions we hear at SolarTherm UK is:
“How do I afford it upfront?”
The good news is that financing solar panels and battery storage has never been more accessible. With a range of solar panels loans and flexible payment options available, installing solar is now achievable without large upfront capital.
In this guide, we break down your options and help you choose the most cost effective route.
Why Financing Solar Makes Sense in 2026
Solar PV systems and battery storage are long term investments – but they don’t have to be paid for all at once.
Financing allows you to:
- Spread the cost over manageable monthly payments
- Start saving on energy bills immediately
- Protect yourself against rising electricity prices
- Increase your home’s value and EPC rating
With the 0% VAT incentive on solar and battery storage running until March 2027, acting sooner rather than later maximises your return on investment.
What Are Solar Panel Loans?
Solar panel loans, also known as Green Energy Loans, are finance agreements specifically designed to help homeowners install renewable energy systems without paying upfront.
Typically, these loans offer fixed monthly repayments, range from 3-15 years and can cover solar panels, battery storage and installation. Usually repayments can be offset against savings. At SolarTherm UK, we work with trusted UK finance providers to help homeowners in the South East find tailored, competitive solutions.
Financing Options for Solar Panels and Battery Storage
Personal Loans
A straightforward option from banks or lenders. Personal loans usually have a quick approval process, fixed repayment schedule and no impact on home ownership. The downside to personal loans is that interest rates can vary depending on credit score, provider and loan amount.
Specialist Solar Finance (Green Energy Loans)
These purpose built solar panel loans often offer better terms than generic lending. They are designed specifically for renewable energy installations and often include finance for panels, battery storage and labour costs. Repayment can usually be offset against savings, meaning there’s usually no increase in monthly outgoings.
Remortgaging or Equity Release
Some homeowners choose to finance solar through their mortgage. Remortgaging usually has a lower interest rate compared to unsecure loans and can be spread over a longer period.
Buy Now, Pay Later and Interest Free Options
Occasionally available through installers or promotions. This is when no interest is paid if the full amount is settled within a set period, ideal for short term affordability. They do usually involve higher costs long term if not settled within the set period.
Is Battery Storage Worth Financing Too?
Yes – pairing your solar panels with battery storage is increasingly popular. Battery systems allow you to:
- Store surplus solar energy for evening use
- Further reduce reliance on the grid
- Maximise self-consumption and savings
- Give you access to time of use tariffs, so you reduce the amount of peak rate electricity you import from the grid
Financing both together often provides better overall value, as installation and loan structures can be combined.
