The number of solar panels is dependant on your energy consumption sun hours and roof size. The bigger the size of the panel the more energy is generated per square metre. The typical wattage of a residential solar panel is around 300w although you can find panels that exceed 400w if you really want your pv system to pack a punch. The typical homeowner will need 28 34 solar panels to cover 100 of their energy usage dependent on location and roof size.

Nonetheless since businesses require on average more power than homes the typically used solar panel size in businesses is 72 cells size or more like that of 96 cells. For example the suntech 250w monocrystalline panel is 1665mm x 991mm x 50mm whhereas the sanyo panasonic panel is 1610mm x 861mm x 35mm but broadly speaking they are all in that range.

There is some variation from brand to brand and if you re installing a large scale solar panel system such as for a warehouse or a municipal building your panels will be closer to 6 feet long. To get these numbers we used high and low panel production ratios to calculate how many solar panels are needed on average. The average size of solar panels used in a rooftop solar installation is approximately 65 inches by 39 inches or 5 4 feet by 3 25 feet. To calculate the number of panels you need divide the hourly energy usage of your home by the wattage of the solar panels.

The difference lies in the size of the solar panel array given that the power demand for commercial businesses is higher than for residential use.
