To compare solar quotes and find out which choice is the best deal, compare the price per watt and not just the total cost. To compare cereal across brands and sizes, you need to compare the price per ounce to find out which choice is the best deal. The smaller box may appear to be the better price, but when you calculate the price per ounce, it may turn out that the larger box of cereal is actually the better price. All other things being equal, like the amount of shade and orientation of the panels towards south, the more kW your solar array has, the more energy it will produce. The number of total watts (w) or kilowatts (kW) in your solar array determines how much energy the system can produce. When comparing the price of your solar array, it is important to compare two different factors: (1) the total price of the system to make sure it is within your budget and (2) the price per watt to see if you are getting a good deal.
