Solar Panel Sizing Guide

Basic Formula

Daily Energy Needs ÷ Peak Sun Hours ÷ System Efficiency = Solar Watts Needed

Example: 1,000Wh daily ÷ 5 sun hours ÷ 0.7 efficiency = 286W panels needed

Regional Sun Hours (Daily Average)

• Southwest US: 5-6 hours
• Southeast US: 4-5 hours
• Northeast US: 3-4 hours
• Northwest US: 2-3 hours
• Midwest US: 3.5-4.5 hours

Common Mistakes to Avoid

1. Undersizing solar panels: Get at least 200W per 1000Wh battery
2. Ignoring surge watts: Appliances need 2-3x running watts to start
3. Cheap panels: Low efficiency costs more long-term
4. Wrong connector types: Ensure MC4 compatibility
5. No expansion planning: Choose systems that can grow

Maintenance Tips

Power Station Care

• Keep battery between 20-80% when storing
• Cycle monthly if not in use
• Store in cool, dry place
• Clean vents regularly

Solar Panel Care

• Clean panels monthly
• Check connections quarterly
• Store flat or fully supported
• Avoid partial shading
