*Your estimated combined savings are based on the recommended number of Longi Solar PV 430w panels included in your package and an electricity export rate of 15p per kWh. For a medium electricity usage home in the UK (using roughly 3500 kWh per year) you can save up to £833 per year by installing a 16-panel system with our 5.32kWh battery storage. You can also earn up to a further £393 per year by exporting excess energy back to the grid at an electricity export rate of 15p per kWh. The calculations follow MCS standard procedure and assume a self-consumption rate of 54% for systems with battery storage and 22% for those without. The current unit rate is based on the energy price set by Ofgem at 27.03p/kWh. Actual savings may vary depending on the specific equipment chosen and your precise annual energy consumption. Savings may also vary dependent on your property location and any obstacles which could cause your roof to be in shade, reducing the solar generation as a result.
** This estimated figure is from the Energy Saving Trust website and is based on fuel prices as of April 2024. The figure is based on replacing an old G-Rated boiler and installing a new A-rated condensing boiler with thermostatic radiator controls (TRVs), as well as a new programmer and room thermostat. This applies to gas heated semi-detached homes in England, Scotland and Wales, but savings will vary depending on the size and thermal performance of your home.
