Solar System Sizing Calculator
Calculate the solar system size needed for your home. Understand how energy usage, location, and panel efficiency affect your solar project requirements and savings.
Step 1: Energy Usage & Location
Understanding Solar Potential
Your solar system size depends on electricity usage, available sunlight, and roof space. Higher sun hours mean smaller systems can generate more power.
Step 2: System Details
Panel Efficiency
Panel efficiency determines how much sunlight is converted to electricity. Higher efficiency panels produce more power in limited space but cost more.

Solar Savings Analysis
Solar System Formula
System Size (kW) = (Monthly Usage × 12) ÷ (365 × Sun Hours × 0.75)
The required solar system size is calculated based on your annual energy needs, adjusted for local sunlight conditions and system efficiency losses (typically 25%).
