WHAT SIZE SOLAR PV SYSTEM DO I NEED?
Firstly, our certified solar experts are always available to discuss the best options for your specific solar needs and provide tools to guide you through the analysis process. Sizing a residential rooftop Solar PV system depends on a few factors; usable roof space, estimated daytime loads, and if net metering options are available.
As a general rule of thumb, 1 square meter can house 150W of rated Solar PV – which corresponds to 1kWh per m2 given favorable weather conditions. This is simply a quick way to estimate total roof capacity and system output prior to considering the other system sizing parameters.
In many countries, net metering is available which benefits solar PV system owners by generating credits from selling back solar energy to the grid. This is especially attractive in areas where high electricity retail rates are employed. Additionally, the ROI time may also be reduced through incentive programs such as Property and Sales Tax exemptions.
