The first step in setting up an off grid renewables system is to minimise your electricity use and heating demands. This is important for all home renewables systems, but if you’re off the grid it’s vital.
To reduce the electricity you need and therefore the size and capital cost of any renewable energy systems for electricity, tasks such as water and space heating can be done by using dedicated renewables such as biomass boilers, ground and air source heat pumps or solar water heating. Surplus wind and solar photovoltaic (PV) electricity could complement these systems once appliance demand is met and your batteries are full.
Reduce heating demands by insulating the property to a high standard.
