Common Uses

People use this calculator when they need a quick way to estimate solar kWh output, electricity savings, and avoided grid emissions.

Measurement: Use environmental, water, weather, energy, emissions, garden, recycling, or fuel inputs to calculate a practical estimate.
Budgeting: Support rough planning for utilities, solar savings, water savings, sustainability projects, conservation choices, or household decisions.
Project Planning: Plan conservation projects, garden watering, rainwater systems, solar scenarios, carbon offsets, recycling goals, or weather reference checks.

Formula or Method

kWh/yr = kW × sun hours × 365 × efficiency; savings = kWh × rate

Example

Example inputs: System Size: 6 kW; Peak Sun Hours per Day: 5 hrs; System Efficiency: 80%; Electricity Rate: $0.13/kWh; Grid Emission Factor: 0.386 kg/kWh

Example result: Using the default inputs, estimated annual production is 8,760 kWh, annual utility savings are about $1,138.80, and avoided grid emissions are about 3,381 kg CO₂.
