Annual Generation (kWh) = Capacity (kW) × Peak Sun Hours × 365 × System Efficiency

Applies National Renewable Energy Laboratory (NREL PVWatts) performance standards.

📢

Solar yields vary by weather and shading. Estimates exclude net metering utility fee changes.

Follow these simple steps for clean energy system planning:

Check your solar installer estimate or monthly utility electric bill (kWh).

Enter your local grid utility tariff rate ($/kWh) and federal tax credit percent.

Instantly view calculated annual dollar savings, payback duration in years, and 25-year lifetime net return.

Transitioning to clean energy lowers carbon footprint while offering long-term hedge protection against rising utility rates.

Input

Solar array rating in kW and local grid electricity price.

Output

Annual monetary savings and full investment breakeven timeline.

How long do solar panels typically last?

Modern silicon solar panels come with a 25-year performance warranty, degrading at roughly 0.5% output per year.

What size battery storage do I need for my home?

An average home consumes 25-30 kWh per day. A 10-15 kWh battery bank provides whole-home backup for basic circuits overnight.
