Science vs Technology. When you hear the term science, it is typically associated with the term technology ââ especially when the two are talked about as subjects in school. Although these two terms are often interchanged, there is actually a sparse difference between the two.
Solar companies can typically get a single solar panel at a price of $0.75 per watt. Therefore, if the solar panel output is 250 watts, that single panel might cost you $187.50. However, if a homeowner is trying to buy one or two panels on their own for a small DIY project, they will likely pay closer to $1 per watt.
Whichever price consumers received, overall, rooftop solar system installation costs are falling. Systems that cost as much as a luxury car five to 10 years ago now cost about the same as an economy car. The gross cost of the average rooftop solar power system before tax credits is $28,203, according to EnergySage.
