Who Is This Kit For?
Homes with High Electricity Usage
This 10kW kit is designed for homes using 1,000–1,500 kWh per month. It covers 80–100% of a typical home's electricity needs, including air conditioning, electric water heating, and appliances. For homes with swimming pools, electric vehicle charging, or well pumps, this kit provides the power you need.
Storm-Prone Areas
If you live in Florida, Texas, Louisiana, or the Carolinas, power outages are a regular threat. The 20.5 kWh battery bank provides 1–2 days of critical load backup, and the Sol-Ark inverter includes a generator port for unlimited extended backup. Never worry about hurricanes, ice storms, or grid failures again.
Time-of-Use Optimization
If your utility charges expensive peak rates (4 PM–9 PM), this kit lets you store cheap solar energy during the day and discharge it during peak hours. In California (PG&E, SCE, SDG&E), this time-shifting strategy can save $200–$400 per month.
Recommended Upgrades
- Double Battery Capacity: Add 4 more EG4 batteries (8 total = 41 kWh) for 2–4 days of backup power. Shop EG4 Batteries →
- Generator Integration: Add a 10kW portable generator ($2,000–$3,000) and the Sol-Ark auto-start kit ($300) for unlimited backup power during extended outages. Request a Quote →
- Expand to 12kW: Add 5 more panels (30 total) for 20% more production. Shop More Panels →
- Ground Mount: Replace roof racking with a ground mount for easier maintenance and optimal tilt angle. Request a Quote →
Installation Requirements
- Roof Space: 575–650 sq ft of unshaded south-facing roof (east/west acceptable)
- Battery Space: 10–15 sq ft of indoor space (garage, basement, utility room) for the EG4 battery rack
- Electrical: 200A main panel required. Licensed electrician required for AC connections and utility interconnection.
- Permits: Electrical permit, utility interconnection agreement, and possibly battery storage permit depending on jurisdiction. We provide line drawings and specifications.
