余った太陽光の電気をためて後で使う場合の節約額を求めます。減る売電収入と追加の維持費も差し引きます。
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.
結果を使用する前に
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.
