如何使用這個計算工具
估算把多餘太陽能存下來、之後使用的節省。記得扣除因此減少的售電收入和新增維護費。
計算方法
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.
使用結果之前
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.
