输入参数
可编辑的示例值估算结果
实时计算结果系统不会自动获取位置或电价，计算以您输入的数据为准。
如何使用这个计算器
输入装机功率、日照小时数和损耗，查看每天及指定天数的发电量。总量假定每天条件相同。
如何使用这个计算器
峰值日照时数表示太阳能的等效量，并非白昼长度。NASA POWER 月平均数据适用于水平面，未考虑屋顶倾角，也不是天气预报。

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.
计算方法
使用结果之前
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.
