The Complete Off Grid Solar System Sizing Calculator
If you don''t, the following calculator will help you list all appliances you plan to use each day, determine their energy consumption, and sum everything up up to estimate your highest daily

A common rule is to store enough energy for 2-3 days of usage, so multiply your daily energy needs by this number. For example, if your daily use is 500 Wh, aim for 1,000 to 1,500 Wh of battery storage.
Each Apex 300 supports 2,400W solar input with dual MPPT controllers, reaching 80% in just 40 minutes—fast enough to recover between morning coffee and an afternoon hike. And for
This tool is designed to help you estimate your daily energy consumption for off-grid setups such as cabins, RVs, tiny homes, or remote solar systems. By entering your appliances, their usage, and
Learn the art of properly sizing your off-grid solar power setup to meet your energy needs. Explore factors such as daily electricity consumption, location, and battery capacity to design a system that
Days of autonomy represent how long you need your batteries to power your home without solar input. This depends on your local climate and personal comfort level.
Off-grid cabins usually need between one and three days of stored energy, known as “days of autonomy.” This buffer helps you maintain reliable power during cloudy weather, storms, or days
Don''t guess on your cabin''s power. This guide provides a step-by-step calculation, real-world examples, and cost estimates to help you choose the right size solar panel for your off-grid needs.
Daily Energy Needs (Wh) = Wattage × Hours per Day. Sum up the total to get your daily energy requirement. Adjust for Efficiency Losses: Add 20-25% buffer to your daily energy needs.
After determining your energy consumption, the next step in off-grid system design is to size your solar panel array. This ensures you generate enough electricity to meet your daily needs
