How many solar panels does a 20kW Solar System use?

As technology continues to improve, the average solar panel efficiency (size vs. output) continues to improve. Depending on the solar panels, a 20kW solar system typically uses between 47 - 61 individual solar panels and requires a roof size of around 80m 2 – 104m 2 to accommodate them. How much energy can a 20kW solar system produce?

How many square meters is a 20kW Solar System?

This is because as panels get large (in Watts) they also become a little bit more efficient. A 20kW system using 370W panels will require about 94.7 square meters of roof to be installed. Each 370W panel measures about 1.75m x 1m. 20kW solar power systems are mostly suitable for small businesses with low energy needs.

How much energy does a 20kW Solar System produce?

As a guide, residents in Perth can expect the highest output from a 20kW solar system with as much as 88.0 kWh of energy produced each day. At the other end of the scale, residents in Melbourne who enjoy significantly less sunlight than those in Perth are likely to produce around 72.0kWh from a 20kW solar system.

Do I need a 20kW Solar System?

Whether or not you need a 20kW solar system will depend on many things. If you are a Commercial customer and you use between 78kWhs and 120.8kWhs then a 20kW solar system could be a good choice to help reduce power bill costs.
