As energy prices continue to rise, more homeowners are turning to solar power as a long-term solution to reduce electricity bills and gain greater energy independence. One of the most common questions we hear at ProStar Energy is:
“Can I get a loan to pay for solar panels?”
The good news is that the answer is yes.
A growing number of UK banks, building societies, and specialist lenders now offer green finance products that can help fund residential solar panel installations. Some schemes even provide 0% interest borrowing, making solar more affordable than ever.
In this guide, we’ll explore the green loan options available in 2026 and explain how homeowners in Dorset, Hampshire, and Wiltshire can finance their solar investment.
Why More Homeowners Are Financing Solar Panels
Installing solar panels is one of the most effective ways to lower household energy costs while reducing your carbon footprint.
However, many homeowners are understandably concerned about the upfront cost.
A typical residential solar installation costs:
- £5,500 to £7,500 for solar panels only
- £8,000 to £13,000 for solar panels with battery storage
- £12,000+ for larger homes with higher energy demands
While solar systems often pay for themselves over time through energy savings, financing can make the initial investment much easier to manage.
Instead of paying thousands of pounds upfront, many homeowners choose to spread the cost through a green loan or home improvement finance package.
What Is a Green Loan?
A green loan is a type of borrowing specifically designed to fund energy-efficient home improvements.
These improvements can include:
- Solar panels
- Solar battery storage
- Heat pumps
- Insulation upgrades
- Energy-efficient windows and doors
- EV charging points
Lenders offer green loans because these improvements can lower household energy consumption and help support the UK’s net-zero goals.
Nationwide’s 0% Green Loan for Solar Panels
One of the most attractive options currently available is Nationwide Building Society’s Green Additional Borrowing scheme.
For eligible mortgage customers, Nationwide offers:
- 0% interest borrowing
- Loan amounts from £5,000 to £20,000
- Terms of up to five years
- Funding for solar panels and battery storage systems
This allows homeowners to install renewable energy systems without paying interest during the agreed borrowing period.
For many households, the savings generated by solar panels can significantly offset monthly repayments.
Other Solar Finance Options Available
While 0% loans are still relatively uncommon, several lenders provide competitive green finance products that can be used for solar installations.
Tandem Bank
Tandem Bank specialises in green home improvement lending.
Their finance products can be used for:
- Solar panel installations
- Battery storage systems
- Heat pumps
- Other energy-saving improvements
Many homeowners choose Tandem when looking for a dedicated renewable energy finance provider.
Lendology Renewable Energy Loans
Lendology works with local authorities to help homeowners fund renewable energy projects.
Benefits can include:
- Fixed interest rates
- Flexible repayment terms
- Renewable energy funding
- Support for energy-efficiency improvements
This can be particularly attractive for homeowners who want predictable monthly payments.
Mortgage Additional Borrowing
Another popular route is borrowing additional funds through an existing mortgage.
Depending on your lender and available equity, this can provide access to lower borrowing rates compared with unsecured personal loans.
Before choosing this option, it’s important to seek independent financial advice and understand the total cost over the mortgage term.
Are There Grants Available for Solar Panels?
While large-scale nationwide solar grants are no longer widely available, there are still schemes that may help qualifying households.
Some homeowners may be eligible through:
- Warm Homes funding schemes
- Local authority energy-efficiency programmes
- ECO-related funding initiatives
- Community renewable energy projects
Eligibility is often based on household income, EPC rating, benefits received, or property characteristics.
At ProStar Energy, we can help direct customers towards potential funding opportunities where appropriate.
Is Solar Still Worth It in 2026?
In short, yes.
Modern solar panel systems are more efficient than ever, and battery storage technology continues to improve.
The benefits include:
Lower Electricity Bills
Generating your own electricity means purchasing less energy from the grid.
Protection Against Future Energy Price Rises
Producing your own power helps reduce exposure to fluctuations in energy markets.
Smart Export Guarantee (SEG) Payments
Homeowners can earn payments for exporting excess electricity back to the grid.
Reduced Carbon Emissions
Solar energy is one of the cleanest forms of electricity generation available to households.
Increased Property Appeal
Energy-efficient homes are becoming increasingly attractive to buyers.
How Much Could You Save?
Savings vary depending on:
- Household energy usage
- Roof size and orientation
- Solar system size
- Battery storage capacity
- Electricity tariffs
Many households in Southern England achieve annual savings of between £700 and £1,300, with some saving even more when combining solar panels with battery storage.
Why Battery Storage Is Becoming Essential
More homeowners are choosing to install battery storage alongside solar panels.
Without a battery, excess electricity generated during the day is typically exported to the grid.
With battery storage, you can:
- Store unused solar energy
- Use stored electricity in the evening
- Reduce grid dependence
- Increase self-consumption
- Maximise overall savings
Battery systems can significantly improve the return on investment of a solar installation.
