Why go solar?

There are a whole range of benefits to installing commercial solar panels. You can count on Grant Store to set up your business with the best, most cost-effective solar solution on the market.

Rising energy costs

  • Fuel prices are going through the roof, and there’s no sign of them slowing down any time soon.
  • Our dependency on fossil fuels and outdated technology is polluting the planet.
  • Repairs can be extremely costly.
  • Increasing demands on an ageing National Grid mean brownouts and blackouts may become more frequent, leaving you with no power source.

Clean, inexpensive energy

  • Enables you to generate your own electricity, massively reducing your energy bills.
  • Zero emissions are produced, making the energy you produce carbon neutral.
  • Solar installations are guaranteed for 25 years+ and maintenance is minimal.
  • Reduced dependency on the National Grid - when everyone else’s lights go out, you’ll still be running on full power.

Every grant that’s available has different criteria that have to be met, and these can include factors such as your income, the type of benefits you receive, the type of property, where it’s located, whether you’re a home or business owner, how much you’re looking to apply for, and more.

Are there any specific deadlines or application periods for grants for solar installations in the UK, and how often do they become available?

This can vary depending on the grant scheme. Some grant schemes have specific application periods and deadlines, while others have ongoing applications.

Can I combine multiple grants or funding sources for my solar installation project in the UK, and are there any restrictions or limitations regarding this?

In some cases, it is possible to combine multiple grants or funding sources for solar installation projects, but it’s important to review the terms and conditions of each grant scheme to understand any restrictions or limitations. We’ll consult with the grant providers or relevant experts in the field on your behalf to help clarify the possibilities of combining grants or funding sources.

If you have any questions about potential solar panel efficiencies for your building, then speak to our team, who’ll be glad to help.
