As my daughter pointed out, attention to the details of Harry Potter's world is also patchy. (1) As everybody knows, the Gryffindor Quidditch team includes several girls. As far as we could tell, all the players in this game are represented as boys. That is a huge demerit for this father of a daughter.
Pricing for Solar Photovoltaic (PV) Systems. Generally, Solar PV systems that generate electricity from sunlight cost between $1.95 to $6 per installed watt. Typically, the larger the system, the lower price per watt. Large commercial systems are typically well below $3 per watt. Residential systems, because of their smaller size are usually somewhat higher.
That $3.00 per watt is, again, on the very low side for the average installer. According to the Solar Energy Industries Association, the average price for a residential system is âjust above $3.50/watt.â Pricing can vary due to specific brand of panels used, inverter brand, and regional pricing differences.
