How do I size an off-grid solar system?

Calculate daily kWh usage, divide by peak sun hours for your location, multiply by 1.25 for losses. Battery bank = (daily usage × days of autonomy) ÷ depth of discharge.

How much does an off-grid solar system cost?

A basic cabin system (1-2 kW panels, 10 kWh battery) costs $5,000-$15,000. A full home system (5-10 kW, 20-40 kWh) runs $20,000-$50,000 installed.
