即時計算結果系統不會自動取得位置或電價，計算以您輸入的資料為準。
如何使用這個計算工具
輸入裝置功率、日照時數和損耗，查看每日及指定天數的發電量。總量假設每天條件都相同。
如何使用這個計算工具
峰值日照時數表示太陽能的等效量，不是白晝長度。NASA POWER 月平均資料適用於水平面，未考慮屋頂傾角，也不是天氣預報。

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.
計算方法
使用結果之前
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.
