POPSSolar Panel Performance Testing This a very good idea. Lack of an across-the-board standard for solar panels has hindered its adoption. Having panels tested independently by the government will boost consumer confidence. Solar tiles are also an example of integrated technology. They are not as noticeable as panels. Their price is also slightly offset by the fact that they replace the need for roofing tiles where they are installed.

POPSPhotovoltaics - How they Work It'd be nice to see a video of this.... The photovoltaic effect was first discovered in 1839. The first photovoltaic cells were made in 1918. Since then Einstein developed photovoltaics. There was a lot of research and development during the 1960's Space Race, when satellites were powered by solar panels. The 1970's saw the beginning of residential solar use. For houses living far off the electricity grid, photovoltaics made financial sense. Prices have since fallen from $30 a watt down to $7 a watt for residential installations. Now due to technology advancing and power costs rising, the price of solar energy is still falling. The future of solar energy looks bright indeed.

POPSSolar TPower in Africa An interesting economic proposition . Countries that were previously disadvantaged by desert and arid land have the potential to become the main suppliers of solar energy.

POPSIncentives may end for Solar Energy This may in fact be a good thing. While I think solar energy needs to grow as a energy source, artificially lowering the price has a limited useful life. For instance, the oil crisis of 1973 caused car manufacturers to make much more efficient cars. Similarly, a change in solar prices could induce cheaper, more efficient solar panels. The stakes are already high for to fill the gap created by oil's high cost. It looks like they may get higher.

POPSThin Film Photovoltaics Thin film photovoltaics are an interesting develpment. Fuelled by a worldwide shortage of silicon (caused by a huge growth in demand for solar energy) thin film solar has risen in popularity. While less efficient (now) than traditional solar panels, thin film is cheaper to produce.
