Solar PV


Earn with SEG

The Feed in Tariff ceased applications back in March 2019. The government has replaced it with a new tariff, the Smart Export Guarantee. Earn up to 5.6p/kWh for any excess power exported, or harness it with batteries.

Power from the sun

If your system produces more that your house draws, you're running for free! Buy less from the grid and reduce your bills. Put the extra power in the batteries for clean power to use later or export and receive an income. 

Less carbon contribution

A typical 4kW residential system can offset over a tonne of CO2 per year. Use this clean power to charge your electric vehicle or heat your home with, instead of using the carbon concoction the grid supplies you with.
