I'm selling my house with solar panels - how do I get the most value?

Solar panel installation is a commitment in more ways than one. While the initial cost of installing solar PV onto your home is often repaid in energy savings and a Feed-In Tariff, a second sense of commitment comes from necessary time spent in one house to see a return on your investment. The li…

Should you buy a battery & how do you choose the right one?

Posted by Ollie Gibbs on 20 July 2017 at 5:06 pm

Should you buy a battery & how do you choose the right one?

Why should you buy a battery? If you have a well-designed PV system you’ll probably have noticed that on some days your system is exporting large amounts of energy back to the grid. This is because your system’s generating more energy than your home is using at that particular tim…

Why buy a hybrid inverter for your solar PV system?

Posted by Aderanti Kudehinbu on 21 June 2017 at 9:45 am

Why buy a hybrid inverter for your solar PV system?

The initial cost of a hybrid inverter is quite high, but this is offset by the ability to use your generated power more flexibly, rather than having to buy energy from the grid when the solar panel isn’t generating. Hybrid inverters have proven reliability across various grid types. Modern …
