How much does it cost to install solar panels?

Solar systems are sold by system size multiplied by dollar amount. This dollar amount ranges from $2.50 – $4.00 depending on added material value, roof type, and height of the structure. For example, if someone needed a 7,000-watt solar system based on consumption and it was priced at $3.00, it would look like this: 7,000watts x $3 = $21,000.00
