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.
The economics of solar power have never been better. As more people have gone solar, the cost of solar panels has come down. The federal tax credit covers 30% of the solar system cost, and in some states there are additional local and utility rebates to offset retail price. You own the solar panel system and its expected useful life is 30+ years. On average, top tier electricity prices have increased about 5% per year for the last 30 years.
