Solar Reaches $1/Watt


The $1 price point has long been touted as the holy grail for solar technology. At that price, it is basically comparable to fossil fuel based delivery of electricity, making it an economically viable replacement for current technologies. On Tuesday, that price point was finally reached. That doesn’t include the cost of installation currently, but it does show some real progress in that area.

Entry #18: Solar Powered Community In Canada


Today I read an article about a unique solar powered community in Canada. The actual location of this community is Okotoks, Alberta. The residents there have created a solar array for their houses that manages to completely power 52 homes. The 52-home solar community has installed an array of solar panels on the roofs of their houses and garages. Glycol solution runs through an insulated piping system, or collector loop, that connects the array of solar panels. The solar panels absorb the solar energy during the daytime and heat the glycol solution. The glycol solution travels through the collector loop […]
