Since 2021 owners of small solar systems in Russia may legally sell surplus electricity. Here is how the scheme works for our Russian branch’s customers.

What the law says
- applies to grid-connected generators up to 15 kW that primarily serve the owner’s own consumption;
- surplus is sold to the guaranteed supplier — the same company you pay for electricity;
- the volume sold may not exceed your own consumption over the billing period;
- for private individuals the income is exempt from personal income tax, and no business registration is required.
Four steps to register
- Application for grid connection of a microgeneration facility;
- simplified technical conditions from the grid operator;
- a bidirectional meter (usually installed by the operator);
- a sale-purchase contract with the guaranteed supplier.
We handle all four steps for our customers, and the inverter must meet the grid codes — the Fox ESS P100 does.

What it pays
Surplus is bought at the wholesale market price — noticeably below your retail tariff. The practical conclusion:
Self-consumption is the core economics (each kilowatt-hour consumed saves the full retail tariff of 6–8 ₽); selling the surplus is a pleasant bonus that monetises summer excess. Systems are sized from consumption, not «as big as possible to sell».
