Grid

With occasional zero export, you can use the power from your solar panels on curtailment days too.

With occasional zero export, your system stops sending power to the grid only when a command comes. To get it, you make a written application to EAC's Distribution System Operator (DSO). Homes and businesses apply the same way, whether or not they have a battery.

The command comes from the DSO or the Transmission System Operator Cyprus (TSOC) at hours of low demand and high renewable output, when the grid cannot absorb any more power.

What happens on curtailment days

With occasional zero export, on curtailment days you can use the solar power you produce, and whatever is left over at midday can be stored in your battery instead of being lost.

A home battery never sends power to the grid, whether there is a command or not.4

If your system can technically bring its export to zero, the law gives you the right for the power you use at home or at your business not to be curtailed, except only in emergencies.5

If you install solar without a battery in a congested area, you may lose more than half of its output.

In a congested area, new solar usually connects only if it never sends energy to the grid. In the example we worked out, a home without a battery loses 53.6% of its output. See how much the same home saves with a battery.

Solar

If your solar panels send energy to the grid, a battery does not save you more today.

If your solar panels send energy to the grid, under EAC's current Net Billing contract a battery does not save you more. See the calculator's figures and when a battery is worth considering.

VAT on home solar has fallen from 19% to 9%.

Since 16 October 2026, home solar panels in Cyprus carry 9% VAT instead of 19%. On a €5,000 system you save €500. The order does not mention batteries or installation.
