Perovskite Offers Shot at Cheaper Solar Energy

A class of compounds first uncovered in the Ural Mountains more than a century ago is now a rock star in the world of solar-energy research.
 
Meet perovskite, the building block for materials that, as a group, have posted unprecedented gains in their solar-energy efficiency—the percentage of sunlight converted into electricity. In the lab, scientists experimenting with perovskite-based materials of different compositions have recently achieved a jump in efficiency to 20%, from around 10% just two years ago.
 
That is still lower than the most efficient silicon-based cells on the market— SunPower Corp. makes cells that are 24% efficient.
 
But because of perovskite's rapid increases in efficiency, researchers think it could be used to make cells that are at least as efficient as those fashioned from silicon, but at a much lower cost.

It's great news to hear that more and more people are employed in the solar industry.. With the prices gradually falling, new user tools available, like the apps http://easysolar.co facilitating the design of the pv system it also gets much easier.. Hence, I hope that the prices will continue to fall and every citizen will manage to afford to install clean energy systems.

TRA SNOW AND SUN - SOLAR TILE MOUNT

TRA SNOW AND SUN - SOLAR TILE MOUNT

You haven't installed a tile mount that is easier to install than the Solar Tile Mount manufactured by TRA Snow and Sun. Solar Tile Mount is used on all tile roof profiles: flat, mid, and high. It is made in the USA of aluminum alloy for strength and excellent corrosion resistance. Solar Tile Mount is built to allow more ease in installation with more rise from the tile surface to the rail for better air flow below panels. The adjustable base is longer than most allowing attachment 6" to the left or right to have the bracket in the base of the pan of the tile and still fasten to the rafter. Solar Tile Mount is adjustable for counter batten systems from ¾" to 3". The horizontal rail is directly above base fasteners giving greater uplift resistance than any other system. For superior waterproofing apply TRA Snow and Sun's butyl backed VersaFlash aluminum flashing. No tile flashing is needed on top of the tile for greater labor and material cost savings.
