Solar documents

• Building permit

  Rooftop/facade PV — no permit up to 30 kW; ground-mounted — declaration/permit by area.

• Connection terms

  DSO technical terms: capacity, connection point, meter — for selling and backup.

• Act & meter

  A bidirectional meter + commissioning act — the basis for net billing/green tariff.

• Contract

  Electricity purchase agreement with the supplier — filed with the act and station diagram.

The order is critical: connection terms → install → meter → act → contract. Selling power without a commissioning act is illegal; a 'for-self' station without connection terms can't legally tie to the grid.
