Solar Radiation in Hungary
• 1168-1460/1150-1332 kWh/m2
• Incoming solar energy to Hungary 1.16*1014 kWh/year. 1250 kWh/m2
• 2900 x yearly Hungarian electrical energy demand
• Household electrical energy demand = for 2 m2 incoming solar energy

PV Potential in Hungary
Yearly average electrical energy production of the solar equipment to be installed potentially in Hungary =486 billion kWh.
Yearly demand of the electrical energy in Hungary today ~ 40 billion kWh.
PV potential more than 12 fold. Remarks for PV fields: + Building facades – Solar thermal collectors
