Как да използвате калкулатора
Въведете мощност, слънчеви часове и загуби. Общото за периода предполага еднакви условия всеки ден.
Как да използвате калкулатора
Пиковите слънчеви часове означават енергия, не продължителност на деня. Месечните средни NASA POWER са за хоризонтална повърхност, без наклон на покрива или прогноза за времето.

Common questions
How does this solar production calculator differ from PVWatts?
The PVWatts calculator estimates the output of grid-connected photovoltaic systems using a solar-resource model and system settings. Solarwise uses the sun hours and losses you enter in a simple energy balance. It does not connect to PVWatts or retrieve weather data; use the official service when you need its more detailed production modelling.
What does a solar PV calculator estimate?
PV means photovoltaic: solar panels that generate electricity. This solar generation calculator estimates daily and period output in kWh from array size, peak sun hours and losses. Use it as a solar electricity calculator for an initial energy estimate, then compare the result with your consumption. It does not model hour-by-hour matching between production and demand.
Метод на изчисление
Преди използване на резултата
Enter sun hours appropriate to your location and selected month. This simple energy model does not fetch weather data or model hourly inverter clipping, orientation or shading separately; incorporate these effects into the inputs. Do not extrapolate one summer month to a full year.
