All-black solar panel from California achieves groundbreaking 19.4% efficiency

California -based Solaria has designed a sleek, all-black solar panel with more than just a pretty face. The company manufactures products with less space between the monocrystalline silicon solar cells for better efficiency than conventional solar panels, which tend to hit 15 to 17 percent, according to the company. In contrast, their black PowerXT solar panel boasts an efficiency of up to 19.4 percent. How is Solaria able to achieve better efficiency? Per a datasheet , they run a patented cell cutting and module assembly process and eliminate busbars and ribbon interconnections. On their website the company claims cells “are cut and overlaid without soldering which creates a highly reliable power unit assembly. The PowerXT module is electrically designed to reduce the power losses due to shadowing across the module by utilizing parallel connections between sets of sub-strings within each quadrant of the module.” Black backsheet and frames complete the look of the all-black panel Solaria describes as “one of the highest power modules in the residential solar market.” Related: Black butterfly wings provide inspiration for superior solar cells The Solaria PowerXT: Residential series panels offer a maximum power of 320 to 350 watt peak capacity. The company said the system would cost less because more efficient panels generate more energy per square meter, lowering installation costs and number of panels installed. Solaria’s datasheet didn’t offer a price for the module. But in a December press release on the PowerXT 350Wp, Auburn Solar owner Peggy Matson offered a hint, saying, “Solaria is great looking, highly efficient, and priced right so we can offer very competitive deals to our customers – often beating our competitors by thousands of dollars.” Solaria’s solar panels come with a 25-year warranty. This week, the company announced they’ve raised $23 million in funding to expand production. They also offer building integrated photovoltaics PowerView products – architectural glass that generates clean power on windows, facades, skylights, or other structures. + Solaria Via Electrek and Solaria ( 1 , 2 ) Images via Solaria

Comments Off on Tesla dumps high capacity Powerwall as it gears up for Mark II release

When Tesla CEO Elon Musk first unveiled the company’s home battery system, the Powerwall , clean energy advocates literally jumped up and down with joy. Designed to store grid energy for use during blackouts, the battery was also predicted to tip the scales for home solar and wind generation. Due to changes in the grid energy market since Powerwall’s release, that didn’t pan out very well, prompting the company to discontinue its 10kWh version and push forward with only the smaller 7kWh option.

Comments Off on New data shows a solar system is installed every 2.5 minutes in the U.S.

The year 2014 was a record-breaking one for the solar power industry around the world, and here in the U.S. we were installing new solar systems at a rate faster than ever before. New data from GTM Research shows a new solar system was powered on every 2.5 minutes last year—which is, if nothing else a huge leap from past numbers, such as one system installed every two hours in 2004.
