The system typically includes:

Daily Output: 24–28 kWh per day
Annual output: Approximately 8,500–10,000 kWh per year

Pairing your 6.6kW solar system with battery storage gives you even greater control over your energy usage. Instead of sending excess solar energy back to the grid, you can store it for use at night or during power outages

Benefits of adding a battery include:

Reduced grid reliance
Protection from rising energy prices
Backup power during blackouts
Increased energy self-consumption and savings

While the upfront cost is higher, long-term savings and independence can make it a worthwhile investment—especially for families using more energy in the evening.
