Solar Light Calculator
Calculate your solar lighting requirements with our comprehensive calculator. Estimate solar panel needs, battery capacity, and lighting costs for outdoor spaces.
Step 1: Lighting Requirements
Understanding Solar Lighting
Solar lights convert sunlight into electricity during the day and use it to power LED lights at night. The battery capacity determines how many hours they can operate without sun.
Step 2: Solar & Cost Details
About Solar Efficiency
Solar panel efficiency varies by technology and location. Monocrystalline panels are most efficient (15-22%), while polycrystalline are less efficient (13-16%). Consider your local climate when planning.

Solar System Breakdown
Solar Sizing Formula
Panel Size = (Daily Energy Use × Backup Days) ÷ (Sunlight Hours × Efficiency)
To calculate solar panel size: Determine daily energy use in watt-hours, multiply by backup days for autonomy, then divide by average sunlight hours and system efficiency (typically 0.7-0.8).
