Cheaper, Greener Energy solutions for your home


Use the following technologies to create a sustainable home solution. Turn your home into a carbon neutral electricity generator

Solar Photovoltaic (PV) Panels

Generate lean, green and mean electricity from the sun to power your home

Battery storage

Store the excess electricity your solar panels produce to use when there is no sun at night or under very cloudy dark day times

Load diversion device (Iboost)

This device will automatically divert any excess electricity generated by the panels to heat the water in your hot water cylinder. First it will charge your battery and any excess after will be diverted to your immersion heater

Solar panel domestic installation on a detached house

Detached House, South Croydon, Installed Nov 2014

Estimated to produce 60%  of their needs.

Cost and profitability

There is currently considerable volatility in the supply, and cost, of the various components required for a solar installation, panels, inverters, batteries, etc.  We are therefore actively updating our guidance on the cost and profitability of solar installations.  We will update our website shortly.

In general terms an average home in the UK uses about 3600kwh (Units) per year.  A typical installation might be 4kwp.  Developments in battery storage have increased the attractiveness of installations and we recommend the inclusion of battery storage in solar projects.   


Returns are tax free and generally attractive compared with, for example, a fixed term savings bond where the interest rate is low, and that’s taxable!
