How It Works

A complete off-grid system has four main components: solar panels sized to recharge batteries daily, a battery bank for multi-day autonomy, an inverter to convert DC to AC, and a charge controller to regulate panel-to-battery charging. Plan for 3 days of autonomy to handle cloudy weather. Total system cost for an average home is typically $30,000-60,000.
