MWh/year production. In most cases homeowners will not be able to use 100% of the electricity they generate because it needs to be used at the point in time that it is generated and this is not always possible (for example if there is nobody in the home using electrical appliances at a particular time). To work out the true impact on your energy consumption of owning solar PV panels or battery storage use our calculator. E = electric energy PV production (kWh/year) Hi = global incident radiation (kWh/m²/year) Pstc = sum of peak power at STC conditions of photovoltaic solar panels (kWp) PR = Performance ratio of the solar PV system (without unit) Calculator : solar PV energy and financial gain The simplest formula is : Solar panels cost $1.77 to $2.20 per watt and a 6 kW solar panel installation for the average home costs from $10,626 to $13,230 after the 30% federal solar tax credit. If you have a 100Ah battery and you use 50Ah, then your DOD is 50%. In an ideal world the solar panels you select will be sufficient to generate enough power each day to exceed, or at least equal, the amount of power required. The monetary savings come about as a result of homeowners reducing the amount of electricity they need to purchase from their electricity supplier. Global incident radiation, Hi : kWh/m²/year emissions. This generator can be connected to an inverter to transform continuous current in alternative current 3-phase or single phase and connected to the grid or to a storage system. kWh/year Location (latitude and longitude) Altitude. The principle of solar photovoltaic is to convert solar energy of light (photons) into electricity. When photons heat special materials they create a displacement of electrons that generate a continuous current.
