Solar Savings Formula
Annual savings are projected with electricity inflation and solar degradation.
Net Cost = System Cost × (1 − Incentive%)
Payback is when cumulative net savings exceed net upfront cost.
Solar Savings Example Calculation
Bill=৳21,060.00/month, 80% offset, system cost ৳1,872,000.00 incentive 30% → net cost ৳1,310,400.00. With rising grid prices, payback is typically around 7-10 years.
