How much will you get paid for electricity you export back to the grid?

It’s likely that you’ll be exporting electricity to the grid at least some of the time, so you should look into how much you’ll get paid for this.

There will also be constraints on how much you can export. This will depend on the details of your individual connection to the network, and the design of the network in your wider area. This may be more of an issue if your on-site electricity consumption is highly variable, which will mean you’ll be exporting more often. A solar installer or consultant will liaise with your lines company to understand these constraints, which may influence the optimum system size.
