Formula

#
Core Formula
Monthly Savings=Bill×Coverage %\text{Monthly Savings} = \text{Bill} \times \text{Coverage \%}

How it works: Calculates how much of your electricity bill solar panels can offset, then determines how many months until the installation cost is recovered.

Worked Example

Monthly bill $150, solar covers 80%, install cost $8,000 → saves $120/month. Payback = $8,000 ÷ $120 = 67 months (5.6 years).

Frequently Asked Questions

What does "solar coverage" mean?

The percentage of your electricity needs that solar panels can cover. This depends on panel size, sunlight hours, and your consumption. 70-90% is common for residential.

What about battery storage?

Battery systems can increase coverage to near 100% but add to the installation cost. This calculator uses grid-tied savings as a baseline.

Do solar panels last long enough?

Most solar panels have a 25-year warranty and can last 30+ years, far exceeding typical payback periods of 5-8 years.
