According to one solar cell system manufacturer, the future of concentrating photovoltaic systems looking rosier by the minute. Organizers of a free teleconference held a month from now, on Tuesday, September 27th at 2PM, will discuss these factors which include new standards for renewable portfolios, improved CPV system efficiency, and lower CPV system costs in depth. Learn the details of what technology updates will contribute to these lower costs, learn what manufacturing techniques have changed, and learn what it means for estimates in terms of cost per kWh and the...

People often ask me what the magic Payback number is for residential solar.  I used to make what I thought were educated guesses, but after talking to hundreds of homeowners interested in going solar, I am convinced that the answer doesn't actually matter.  In fact, I'd say the question doesn't even matter.  I think Brian Keane knows what I'm talking about.  I recently found one of his articles titled "Policies that advocate for solar consumers will create jobs".  In the article, he points out that "without national policies that benefit these solar consumers, their...

It is common knowledge that solar still has a way to go before it can compete against utility-scale coal. Even if you take into account the social costs (pollution and other environmental affects) and the fact that the existing energy infrastructure is heavily subsized in account, most experts will say that coal is still better than solar (the differences of opinion generally have to do with how much value experts assign to pollution, i.e. being able to breathe clean air).

Most people also recognize that for innovation to occur in an unproven industry, proper incentives must be put in place...
