In 2010 Schott Solar made waves with the world record for a module efficiency of 17.6 percent with their multicrystalline cell concepts. With more than three years of development and research under their belts they were able to apply their expertise to monocrystalline.
Utilizing selective emitter technology and passivated rear side contact (PERC) they were able to achieve a cell that is now the world’s first 156 mm x 156 mm screen-printed solar cell with 20.2 percent efficiency. (Laboratory results in conjunction with The Schmid Group from Freudenstadt, Germany)
Schott Solar reports they are energized by these findings and are working on optimizing the manufacturing process for development of highly efficient modules. To follow the progress of Schott Solar’s new cell technology they will be sharing information at The 26th European Photovoltaic Solar Energy Conference and Exhibition (EU PVSEC).

Quite often we get calls at SES 21 USA from homeowners or installers who are struggling with some design issues: what to do about trees that shade or how to handle odd pitched roofs. A number of times we have seen people assume that they are not candidates for solar and give up quickly on the idea.
We recently had a resident call in with a bit of a tricky roof. As you can see in the photo his roof has many different pitches and the gables which cause shading in the late afternoon. A roof mount was definitely an option but the installer and customer decided on this ground mount system. The customer had the space for it, unobstructed by trees or other buildings. Plus he can really maximize his ability to produce solar power with this ground mount system. Did we mention the home is in very sunny South Texas!
Congrats to the homeowner and the installer for designing such an efficient and practical source of energy.

This must be the innovation and positive impact of competitive forces that Texans were promised in 2002 when Governor Perry and his very own PUCT (Public Utility Commission of Texas) deregulated IOU’s (investor owned utilities) in Texas and when the TPUC discarded the North Texas TXU franchise by allowing it to be sold to a private equity consortium (KKR, TPG, and Goldman Sachs).
Hey, good work Governor Perry, TPUC, Energy Future Holdings, and private equity smart guys. It was so boring and old fashion with Dallas Power & Light. They just sat there. Now we have exciting REP’s (retail electric providers) that offer consumers choice (i.e., power to choose).
TXU, our once proud franchise utility, has joined the throngs of predatory REP’s in Texas. It’s business in Texas. What a great idea and income opportunity . . . let’s use electricity service to exploit low-income families, the elderly, and customers with poor credit.
Now, the least fortunate electricity consumers actually have no choice in Texas: they can prepay their electricity with a large deposit, or they can prepay their electricity with a large prepayment. It’s power to choose in a perverse manner.
TXU argues that the plan gives TXU the ‘ability’ to serve customers that don’t qualify for standard service because of bad credit. Really? No ability without a predatory plan?
Also . . . ‘customers want this service because they can pay as much on their electricity bills, when they choose to do so.’ OK now I understand, you can pay your electricity bill (at a higher electricity rate) several times a week or month instead of a normal billing cycle . . . now that’s very convenient.
In addition, with ‘smart meters’ TXU can put their low profile customers in the dark at any time of day when their ‘prepayment’ is expended. Awesome.
Maybe municipally owned Dallas Water Utilities is watching . . . they can do the same thing. Prepay your water bill and sanitary sewer service – another convenience for low-income families!
TEXAS . . . honestly, have you had enough?
Begin to separate yourself from our ‘power to choose’ retail electricity providers. Install a PV solar system on your home or business. Produce a portion of your own electricity. Hedge your electricity bills, and distance yourself from the usual cast of inside players.
PV is available now, it’s affordable and economic, it’s scalable (any size system works fine), and your investment in PV increases the value of your home or business. Learn more, and join the solar movement.
You will have no regrets. It’s time to make a move. Light from light . . . cool energy.

Bosch Solar Energy announced that Bosch silicon cells have achieved a world record. The independent calibration laboratory at Fraunhofer Institute for Solar Energy Systems has confirmed that a degree of efficiency of 19.6 percent has been reached for Bosch monocrystalline solar cells*. Normally, a silicon-based screen printed solar cell will achieve efficiencies of 17 to 18.5 percent. The output of the cells can reach an outstanding 4.73 Watt peak.
Bosch Solar Energy has been working on these new record-breaking cells for quite some time. The design structure on this new altered cell is referred to as PERC which stands for “Passivated Emitter and Rear Cell”. The rear side of the cell as well as the front was optimized for the solar cells’ optical and electrical properties.
An immediate practical application for these optimized cells is that the cell’s performance is improved under weak lighting conditions and increased ambient temperatures. This means a higher energy yield for solar consumers even during winter months or overcast days.
Most consumers are familiar with Bosch power tools or home appliances. Installers and consumers alike should familiarize themselves with Bosch Solar. Founded in 1886, Bosch is a worldwide company and a market leader in patents. If you have a twenty-five year warranty on your solar panels you’ll want a company that you know will be around for a long time!

The solar market is growing and so are we!
We needed more office and warehouse space and luckily found the perfect space right next door.
You’ll find us at the same business complex at 2515 Tarpley Road, but in Suite 100 instead of 118.
