How do I estimate the size of an off-grid Solar System?
Use our Off-Grid solar calculator tool below to estimate system size. Check out our video on off-grid sizing for details and more information on the design process. Steps to use the off-grid calculator: Enter your zip code *, and we'll look up the the sun hours in your area. *Must enter zip code to gather data.
How many solar panels does an off-grid home need?
The number of panels depends on your energy consumption and location. A typical off-grid home needs 10-30 panels (3-10kW). Calculate by dividing daily watt-hours needed by peak sun hours, then divide by panel wattage. Add 20-30% margin for inefficiencies and future expansion. What size battery bank do I need for off-grid?
How much does an off-grid solar system cost?
Off-grid system costs vary from $10,000 for a small cabin system to $50,000+ for a full-home system. Key cost factors include energy requirements, battery capacity, component quality, and installation complexity. Battery storage typically represents 30-50% of the total system cost. How many solar panels do I need for off-grid living?
What components do I need for an off-grid Solar System?
Below is a combination of multiple calculators that consider these variables and allow you to size the essential components for your off-grid solar system: The solar array. The battery bank. The solar charge controller. The power inverter. Simply follow the steps and instructions provided below.
How do I calculate a solar system sizing tool?
Calculate the ideal solar panel, battery, and inverter requirements for your energy needs with our Off-Grid Solar System sizing tool. Solar Array (W) = Daily Usage (Wh) ÷ Sun Hours ÷ 0.8 (efficiency) × 1.3 (safety margin) Battery Bank (kWh) = Daily Usage (kWh) × Days of Autonomy ÷ Depth of Discharge
Is off-grid solar right for You?
Off-grid solar is great for those with RVs, boats, or a backyard shed or guest house. For those who live in isolated areas that lack the infrastructure, off-grid solar might be a necessity. Going off the grid means you keep all the power you generate, and there’s no interruption in service when the power grid fails.
