How long does a Solar PV system take to pay itself off?
A typical 4kWp south-facing system will pay itself back in 7 years - after that the system will generate pure profit. It can be a little longer for smaller systems or those at poorer orientations, but we can confirm your estimated payback time during your no-obligation site survey.
Can my Solar PV panels provide hot water?
With the use of a Smart Switch, any un-used electricity can be used to provide your home with free hot water.
Is a Heat Pump right for me?
Heat Pumps are most cost-effective for new build properties that are well insulated and make use of underfloor heating. But you can also see huge benefits in older, retrofit properties. If your Oil & LPG bills are high, you could save a huge amount with a well sized Heat Pump. To ensure you get the perfect system, we’ll carry out a full heat loss survey throughout your property.
What is Powerwall?
Powerwall is a rechargeable battery for your home, that stores energy, either from the grid or a Solar PV system, and makes it available on demand. It’s compact, sleek and easy to integrate into your property.
How much does a Solar PV system cost?
That depends on the size of the system you’re after. Our smaller systems can be installed from as little as £3500, with our 4kWp systems starting at £4,500 (inc. VAT)
How much can I generate from Solar Panels?
A south-facing roof with a 4kWp solar system can generate over 4000 units (kWh) per year. On average, a household will use around 3200 units per year, so with a good system you can run your home completely free.
Do Heat Pumps require a lot of maintenance?
A properly installed Heat Pump requires next to no maintenance. We simply recommend an annual service to ensure that everything is running as expected.
Do Heat Pumps provide my property with hot water?
Our Heat Pumps will provide your property with all the hot water you need throughout the whole day
What can I use Powerwall for?
There are a variety of applications for Powerwall. If you have a Solar PV system, you can store your excess generation during the day and use that energy to power your property at night. You can draw from the grid at times with a lower rate, and then use that energy during more expensive times to reduce your bill. You can even monitor your real-time energy usage with the Tesla mobile app.
