How much do you get for selling solar?

4-15p per kWh depending on SEG supplier and tariff. Fixed rates: 4-6p. Variable (Octopus Flux peak): up to 24p during 16:00-19:00.

Is it worth selling solar electricity?

Better to SELF-CONSUME (saves 24.5p/kWh) than export (earns 4-15p). But any surplus you cannot use should definitely be registered for SEG — it is free money.

Selling solar electricity to the grid — You earn 4-15p for every kWh of surplus solar you send to the grid — registered via SEG.

Can you sell solar electricity to the grid?

Yes, you can 'sell' surplus solar electricity back to the grid through the Smart Export Guarantee (SEG). When your panels produce more than you use, surplus flows to the grid and your supplier pays you 4-15p per kWh exported. This is not technically 'selling' (you do not negotiate a price) — it is a regulated payment scheme. Annual SEG income: £80-£300 for a typical 4kW system. You need: MCS certification + smart meter + SEG registration. Free to register, takes 5 minutes.
