To get grant of €800 see table and example below

0 – 170m² per house area 10kWh/m²
171 – 200m² per house area 1700kW
201 – 250m² per house area1850 kW
250m² + 2000kW
  • Example 1
    2000ft² house equals 186m²
  • 186m² house equates into 1700kW/m²
  • GRANT panel equals 525 watts
  • divide 1700 kW by 525 watts
  • equals 3.23 panels
  • 4 flat plat panels is required for a 2000ft²
  • Example 2
    1300ft² house equals 121m²
  • 121m² house multiply by 10kW equals 1210kW/m²
  • GRANT panel equals 525 watts
  • divide 1210 kW by 525 watts
  • equals 2.30 panels
  • 3 flat panels is required for a 1300ft²
