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 average price of a solar panel has declined by 60% since the beginning of 2011, according to GTM Research. And, according to CleanTechnica, a website dedicated to renewable energy news, the price of solar power has fallen rom $76.67 per watt in 1977 to 74 cents today.
