Once you've made the decision to become a generator, the next step is to select the right renewable energy technology for your home.

There is a growing number of technologies entering the market and it can be challenging to identify which is the most suitable. You may, for example, have your heart set on a wind turbine, but there is a chance it might not be appropriate for your situation.

To help you make the best choice, we have created a detailed assessment survey to help our team of experts work out which technology will work well for you.  Before you do that, it's worth having a look at the basic requirements for each technology;

Solar photovoltaic (PV)

• South, south-east, or south-west facing available area
• No casting shade for large proportions of the day
• At least 10m² of available space

Solar thermal

• South, south-east, or south-west facing (ideally with a 45 degree tilt) available area
• A compatible boiler/hot water system
• An available space of at least 2.5m²

Wind turbine

• West facing
• A wind speed of over 4.5m/s at 10m above ground level
• No obstacles within 50m of the site and the westerly wind

Heat pump

• For this technology your key requirements fundamentally depend on which type you choose to install. For example, if you select a ground-source heat pump, these work best with under-floor heating, air-sourced heat pumps, however, work well with radiator heating systems.
• We would always recommend making sure your property is well insulated before you think about installing a heat pump.
