如何使用这个计算器

估算把多余太阳能存起来、留到以后使用的节省。要扣掉因此少拿的卖电收入和新增维护费用。

计算方法

Daily savings = stored input kWh × (round-trip efficiency × avoided import rate − foregone export rate). Annual net savings = daily savings × operating days − maintenance. Simple payback = installed cost / positive annual net savings.

方法说明 →

使用结果之前

Daily stored input must fit battery capacity, charging limits and real surplus. All delivered energy is assumed to displace imports. Constant tariffs and performance; no financing, degradation, replacement or discounting. Backup reliability value is excluded. Negative savings mean storage loses money under these assumptions.
