A few pieces of promising news from the world of solar power and heating.

The Worldwatch Institute estimates that the cost of photovoltaic cells may drop by as much as 40% in the next few years. One factor contributing to this is the increase of manufacturing of photovoltaics in China, such as the new facility announced by Suntech, a key supplier of building integrated solar products.

Bosch Solar Thermal Systems say they have seen a 60% increase in year to date sales over the same period last year and expect to sell 150,000 units this year.
