Q5: My house is 1500 square feet. Which system should I choose?

A: Great question! The best system depends on your daily electricity consumption, not just the size of your home. However, square footage gives us a general idea:

• A 12kW off-grid kit is ideal for homes around 1200–1500 sq. ft. with moderate power usage (about 10–15 kWh per day).
   

• A 15kW off-grid kit is recommended for 1500–2000 sq. ft. homes, especially if you use air conditioners, pumps, or more appliances, and consume 15–20 kWh per day.
