Boost your usage with batteries

Solar PV generates electrical energy from the sun by collecting photons in specially designed silicon cells which produce electrical DC (direct current) energy. These cells are arranged on a panel and sealed under glass. The DC energy is fed to a device called an inverter, which converts DC energy to AC (alternating current) to feed into your home’s consumer unit (fuse board). As the voltage generated by the inverter is slightly higher that that supplied from the grid, your home will use the energy first, with excess going to the grid. If you have a battery, then the inverter will sense how much excess energy is being produced and use it to charge the battery for use later.

By generating electricity from the sun, you can use less electricity from your utility company. If your solar system generates more electricity than you need, the excess can be sold back to the utility company, which can result in net metering credits on your bill. This can significantly reduce or even eliminate your electricity bill.

By exporting your excess solar energy to the grid, your energy supplier could pay you for the energy under the Smart Export Guarantee.

Low maintenance and long lifespan: Solar PV systems require very little maintenance, which can save you money on repairs and upkeep over time. Additionally, solar panels have a lifespan of 25 years or more, which means you can continue to benefit from them for a long time.

Solar PV systems can increase the value of your home, making it more attractive to potential buyers if you decide to sell your home in the future.

Overall, the savings from solar PV systems depend on a variety of factors such as the size of the system, the cost of electricity in your area, and the amount of sunlight your location receives. However, for many homeowners, solar PV systems can be a wise investment that provides significant long-term savings.

Solar thermal panels sit on your roof and attract the sun’s infra-red heat energy. This energy is transferred into a liquid which is pumped to a hot water cylinder to heat water for domestic use.

Solar thermal is also an excellent (and free!) method of heating swimming pools of all sizes.

Wiltshire Energy has the in house experience of installing small domestic solar systems, up to the largest solar thermal system in the UK.

What our customers say

Mr Warden
Home owner
This was to install a heat pump meter, rapid response to enquiry, very reasonable quote, arrived on time, did the work neatly and efficiently. Very friendly and reassuringly competent. Highly recommended.
J Rowe

The team were very professional, they informed me how the installation would be carried out and worked around my schedule. I’m very happy with the results and have noted a vast improvement in my electricity bill. Better still; I don’t have a gas meter anymore!
