In assessing a CPV or CST technology you need to consider both the target applications and the completeness of their design concept for that application - does the team have the expertise to make it work? 

Concentrating photovoltaics (CPV) are not quiet ready for primetime on commercial rooftops. (a) Commercial roof tops are highly dependent on financing via power purchase agreements (PPA). (b) Concentrating photovoltaics are an unproven technology in terms of performance, reliability, price and O&M...

There is an interesting dichotomy in how most Americans, both the public and the leadership, address alternative energy.  We mouth the rhetoric of "there's no one answer" to replacing present energy conversion and then are as petulant as a child who got underwear instead of a bicycle for Christmas,...

Despite a horrendous housing market, solar powered installations on homes, especially new ones, are becoming a measurable market niche.  This trend is being noted in mainstream homebuilder publications like housingzone.com, which has until now treated solar as something way into the future. ...

In the Paul Newman movie "The Private War of Harry Frigg", an opening scene has a bunch of generals in a steam room arguing over a map where the enemy is.  After a few minutes, the enemy shows up at the door and takes the toweled lot away.  So is the argument over what's worse, climate change...

Just when you think it's over, and the US solar and wind industries will have to scramble to finish 2008 installations and sweat out 2009 inactivity, Congress has passed fairly close versions of solar and wind power incentives that promise to be at least an adequate patch over to next year, and possibly...

Despite trepidations over the lapsing of US federal incentives, the domestic photovoltaic market continues to consolidate to take advantage of better economy of scale.  Photovoltaic installations in the US now number over 10,000 a year, growth that will continue to increase once new federal incentives...

This story on a US based installer setting up shop in Mediterranean Europe is a good example of the challenges of dealing with what was until recently two of the hottest PV markets in the world for 2009 - Spain and the United States.  The dynamics of what the changes in incentives will do and how...

The new Spanish Feed In Tariff (FIT) - if passed by the government will have significant impacts on the global PV Industry. As the Spanish market will be significantly smaller than in previous years all the modules that are produced and were designated for the Spanish market will need to find...

Feed in tariffs, a way to provide measured funding for photovoltaic and other renewable energy systems, has been successful in bringing these technologies to market.  Paying only for performance, requiring outside financing, steadily reduced rates and caps on rate impacts have enabled solar and...
