If each solar panel has an average wattage of around 350W (typical for residential installations), you would need approx 56 solar panels to reach a total system capacity of 19,500 watts or 19.5 kW.

A solar power system’s average cost per watt ranges from $2.50 to $3.50. Using this range, a 19.5 kW solar power system could cost approximately $48,750 to $68,250 before any incentives or rebates are applied.

-Each 330-watt solar panel occupies approximately 1.675 square meters of space. Therefore, for a system comprising 80 panels, you need around 134 square meters of space. However, allocating around 140-150 square meters is advisable to account for roof type and panel capacity factors.

As a rough estimate, assuming standard-sized solar panels with an average efficiency, you would need approximately 1,200 to 1,500 square feet of unobstructed roof space to accommodate a 19.5 kW solar power system. However, consulting with a solar energy provider or installer who can assess your roof’s suitability for solar installation and provide a more accurate estimate based on your specific circumstances is essential.

The average payback period for a 19.5 kW solar power system can vary significantly depending on factors such as the cost of electricity in your area, available incentives or rebates, the efficiency of your system, and how much energy your system generates. As a rough estimate, the payback period for a solar power system is between 5 to 10 years. However, in some cases, it can be shorter or longer.

On average, a 19.5 kW solar power system could generate between 60,000 to 80,000 kWh of electricity per year, depending on location and other factors.

Potential Savings = 70,000 kWh/year × $0.12/kWh= $8,400 per year
