In addition, you’ll have the cost of the inverters, the mounting system, and the labor. However, according to Waller, how much energy a panel produces depends on its quality, type, material, and location.įixr estimates the panel cost for this size system at around $7,500 to $18,000, depending on each panel's type, brand, and wattage. Since the typical solar panel produces about 1 kWh per day, you’ll need around 33 panels for this illustration. For example, a monthly average of 975 kWh gives you a daily average of 32.5 kWh. To calculate your monthly average, add up the monthly kWh used for a year and divide by 12.įor a daily average, divide your monthly kWh average by 30. Next, find the 'kWh used.'
