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.
The bulk of the price of going solar is now the âsoft costsâ (installation, permitting, etc.) rather than the solar panel cost. Again referencing the latest US Solar Market Insight report, the average installed cost of a residential solar panel system was $4.72/watt. However, prices vary tremendously by region.
