如何使用这个计算器
比较选定年限内只用电网和安装太阳能的总开销。安装后仍需支付的电费也要算进去。
计算方法
Grid-only cost grows with the tariff assumption. Avoided grid cost starts at (current bill − remaining bill) × 12 and is adjusted for tariff growth and solar degradation. Solar option includes upfront cost, remaining bills, fixed annual maintenance and replacement.
使用结果之前
All monetary inputs must use the same currency. Assumes the tariff escalation applies to the entire modelled bill; fixed charges and time-of-use rates may behave differently. No financing, discounting or export revenue is included separately.
Can the solar option cost more?
Yes. High upfront costs, low savings, maintenance or a short analysis period can make solar more expensive in this scenario.
