the most efficient solar power system ever

There are two types of solar energy systems, solar photovoltaic which turns sunlight into electricity and solar thermal which harnesses the warmth of the sun to provide heating. If you want both typically you’d have to install two separate systems. Although PVTSolar, an innovative company offers a solar energy system that not only produces electricity but can provide heating all in one system! They took a smart approach in turning a problem into an efficiency by controlling the heat that typically reduces performance on solar photovoltaic panels into an asset for water and space heating. By taking the heat that typically harms photovoltaic production and putting it to good use, PVTSolar claims they have the most efficient solar energy system in the world. According to the company, the PVTSolar power system will not only look good but it will cost 25% more than a regular photovoltaic system but since it can provide both your electric and heating needs the system will save you more money in the long run. What do you think of PVTSolar revolutionary echo solar energy system that can knock out more of your energy...

The Photensity Solution

What if you could divide the sun’s rays into three different energy streams? Commercial buildings, which are associated with large carbon footprints and high energy bills can take advantage of BrightPhase Energy’s Photensity which is a crossbred of energy efficiency and a solar panel. The unique looking solar panel not only generates electricity but can be used for heating water and the building itself. The most interesting feature of the solar panel is the daylighting technology, which provides natural lighting for the building that augments traditional interior lighting, thus reducing the building’s lighting load. Confused? Check out how the Phototensity works. According to the company, combining solar energy and energy efficiency in a single solar panel provides 2X – 3X better rate of return than solutions that just produce a single energy form. A building owner can reduce up to 50% of there energy bill through an all-in-one solution like the Photensity and depending on the installed conditions may bring down the break even point to less than 4 years! We’re seeing more of these “all-in-one” solutions being developed lately, do you think all-in-one systems will play a significant role in the...

AC Sun’s Solar Air Conditioner

A while back I wrote about a solar air conditioner called the Greencore Air that was a highly efficient air conditioner powered by photovoltaic (pv) panels. This week a Danish company AC-Sun, announced they are developing a unique solar air conditioner. We’re fascinated with solar air conditioners because typically these are the largest and most expensive load on homes and businesses across the world, which can make a very cost effective application of solar energy if a company can release a reliable product. The most interesting part about AC-Sun’s solar air conditioners is that instead of using solar panels to generate electricity to power an AC, it uses solar thermal technology which boils water, creates steam to drive a turbine which can cool a room. It’s using the sun’s heat to cool a room! The AC-Sun’s system is based off an already known thermal process, which includes a traditional solar thermal panel that provides energy to an expander that ends up operating a compressor. A compressor is a critical unit in air conditioning and is important in the overall process of creating cool air. Unfortunately, you can’t buy AC-Sun’s solar air conditioner today, they are still developing the product and according to the company the product will be on the market in the middle of 2010. What do you think about solar air conditioners? This is a very interesting niche of solar energy, has anyone seen other companies dabbling in this...

Heat your water, generate electricity, one panel.

At the ASES Solar 2008 conference we saw some great technology improvements and creative out of the box thinking in the solar industry itself. One technology that stood out was a solar PV panel with the ability to heat water. One panel does the jobs of two different technologies (Solar PV & Solar Thermal) The great part of the new solar energy collector is not only to heats water and produces electricity with less surface area, but the water within the panel water cools the PV Panel before the water is heated and used for hot water. According to the company there is a 10% gain in efficiency of the PV Panel. The industry seems like to get much more innovative. According to representatives at the booth the founder of the company used to work for Intel and understands how to cool silicon since heating of silicon was a common problem in the computer processor industry. The solar energy collector snaps on top most solar pv...

ASES Solar 2008 Expo

We’re at the ASES Solar 2008 Expo in sunny San Diego, California this weekend. This show was interesting because there was a wide range of products on showcase we very well developed companies to startups. Some interesting technologies we saw included solar panels which produced electricity and heated water from the same panel, quicker and easier ways to mount solar panels, standardized systems which make it easier for general contractors and other do it yourselfers install solar power with one days work. The expo also featured concentrated photovoltaic solar panels, it seems like this technology is showing up much more at renewable energy tradeshows and as the product continues to develop it will soon hit the consumer market. The expo hall had a lot of emphasis on solar water heating; there has been a lot of progress in the technology, from newer and better evacuated tube and very interesting looking flat plate collectors. It’s great being at the trade shows because we can really find out what is upcoming in the market and deliver that information to you, so you can make educated decisions about your clean energy...
