Still need help to determine how many solar panels you need? We'll design and provide estimates on a solar system for you.
Sunlight affects how much energy your solar panels generate. As a rough estimate, let’s assume that a 310W solar panel produces 1.24 kWh a day, and your location receives 4 hours of sunlight per day. Explore more
Next, how much of your current kWh usage do you want to offset with solar power? 100%? 80%? 50%? Multiply this percentage with your daily kWh usage. If you want your solar system to account for 80% of your energy consumption, here’s how the calculation would work: 37 kWh per day x 0.80 = 29.6 kWh. Explore more
One solar panel produces about 1.24 kWh per day. In the example above, you would need 24 solar panels to account for 80% of your average consumption (29.6 kWh daily usage divided by 1.24 kWh per panel). Likewise, if you wanted to account for 100% of your daily kWh consumption, you would need 30 solar panels (37 kWh daily usage divided by 1.24 kWh per panel). Explore more
