Assuming your house is connected to the national grid, you can sell any surplus electricity you generate back to your energy supplier, (although it is sometimes hard to get the appropriate red tape completed).
Selling electricity is one the best ways to earn passive income for your household.
There are basically two options for selling your renewable energy back to your electricity supplier. If you’re prepared to fill in a lot of forms it’s possible to get paid the same price per unit exported as you pay to buy it off your supplier net metering. Alternatively, there’s an easier option where you get paid less per unit generated, but it’s a lot less hassle.
THE NET METERING OPTION
If you’ve invested in a solar roof system, and you expect to produce a lot of surplus electricity, you’ll want to set up a net metering arrangement. This means that your energy supplier will pay you a decent price for every spare kWh of electricity generated that you don’t need yourself. It does mean you’ll need to get an OFGEM-approved Export Meter – your supplier may be able to help. You also get to keep your ROC entitlements with this option.
