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.
Last update: June, 2014. Solar panels have been just as cheap or cheaper than grid energy since 2013, in most places. Solar is unlikely to continue to get a lot cheaper, though, because the price of the panels has dropped so much that most of the system cost is now for installation, not for the panels themselves.ast update: June, 2014.
