How much power does a solar system produce per month?

As a rule of thumb, a system that could produce 2000 kWh per month, would be rated at around 14 kW (kilo-Watts) of power. A system of this size would roughly consist of about 44 residential solar panels that are each rated at 330 Watts (0.33 kW).

How many solar panels do I Need?

Let’s plug 300W and 5 peak hours in the calculator. Here’s what we get: That means that we would need 59 300W solar panels to produce 2,000 kWh per month if we get little sun (5 peak sun hours). You can use the calculator to make pretty much any number of solar panels calculation.

How do you calculate solar energy usage?

3. Multiply your daily energy usage by the percentage of your power bill you want to cover with solar. If you want to cover half of your power bill, for instance, you’d multiply your daily energy usage by 50%. This gives you an estimate of how much energy your solar system needs to produce on an average day.

How do you calculate solar system inefficiencies?

Multiply your solar system size by 1.2 to cover system inefficiencies. There are inefficiencies in any solar system due to factors like shading and soiling. So this step is a simple way to try to account for system losses. So, in this example, you’d need a 3 kW solar system to meet half of your daily energy needs.
