Comments Off on New 3 in 1 Roof solar tiles power your house for half the price of a Tesla roof

Tesla is getting all the attention when it comes to solar roofs , but some competitors out there are innovating in ways that even Elon Musk hasn’t thought of. 3 in 1 Roof , for instance, offers insulation, extreme wind protection and solar power, all in one. The solar roof system comes in a huge range of finishes, has a lighter load than traditional slate tiles, and is the first to claim zero heat transference into the attic – so it reduces your heating and cooling costs while providing you with clean, green energy. All at about half of the price of a Tesla solar roof. The Ft. Lauderdale-based company calculates that its offering will be about $11 less than Tesla’s solar roof per square foot. It’s also lighter than traditional slate roofing at just 110 pounds per 10 square feet, which means that architects can engineer homes with structures designed to support lighter loads. The roofs are designed to eliminate condensation between the attic deck and insulation, preventing mold and rot. The roofs are also hurricane resistant, standing up to winds at 200 mph.

If you want to nab one, the company is accepting $500 deposits and guarantees it will be ready for installation in 2019 – or you get your deposit, plus $500 back. You can also get a free car station charger if you are one of the first 1,000 to place an order. + 3 in 1 Roof

Tesla’s Powerwall faces stiff competition from several other storage products

Comments Off on Tesla’s Powerwall faces stiff competition from several other storage products

While Tesla ‘s Powerwall may be the most well-known example of residential solar energy storage systems, it is not the only one and is facing increased competition. Nearly all major residential solar companies are now developing a similar household energy storage system, either independently or in collaboration with another company. Among those companies, SunRun, Vivint Solar and SunPower seem to be the most viable competitors to Tesla’s residential solar operations. The increased competition is good news for consumers as well as the renewable energy sector generally, indicating that the industry is maturing and spreading. SunRun now maintains the largest market share in the American residential solar industry , in part thanks to its ability to work with internal and external installation partners. This means that SunRun is able to more quickly scale up its distribution. The company’s Brightbox system incorporates LG Chem batteries into a control system (designed by SunRun) and is currently available in Arizona, California, Hawaii, New York, and Massachusetts , with more states coming online in 2018. Related: Nova Scotia Power pioneers new energy storage system using Tesla Powerpacks Vivint Solar is collaborating with Mercedes-Benz to develop a 2.5 kW-hr energy storage system that can be expanded up to a 20 kW-hr system for household needs. Mercedes-Benz already has energy storage products available in the more developed European market, which puts it in a good place as the American market grows. Last but not least, SunPower will launch its home energy storage system under its Equinox product line in 2018. Because they are geared towards high-end customers, those with the most funds to invest in new technology, it may see more rapid growth than its competitors. Regardless of the commercial success of any individual company, the flurry of activity in the American residential energy storage is a welcome sign as the United States, like the rest of the world, must move forward towards a clean energy economy.

Beijing-based firm META-Project just unveiled a triangular cabin overlooking Songhua Lake in China’s northeastern Ji Lin province. Located at the top of a steep ski slope, the Stage of Forest lookout – which is clad in Shou-Sugi-Ban wood – peers out over the amazing landscape, and provides a respite for skiers who need a break before swishing down the mountain. The building is located on the edge of a forested hillside overlooking the Songhua Lake Resort – a popular winter destination. Jutting out over the landscape, the wood and concrete structure is a solemn presence against the snow-covered mountains in wintertime and it’s camouflaged by lush vegetation in the summer months. In addition to providing a place to rest on the slopes, the building will also be used year-round for exhibitions, conferences, workshops, and public and private events. Related: ‘Top of Tyrol’ Lookout Platform Offers a Bird’s-Eye View of Austria’s Stubai Glacier The building’s “floating” design minimizes its footprint as much as possible. The compact concrete base occupies minimal square footage, while the larger volume provides a spacious interior to enjoy the stunning views. The building consists of a concrete shell topped with charred cedar shingles, which emit a silvery tone under the sunlight. From the first floor, visitors can climb to an open-air viewing platform clad in untreated red cedar . Oval windows in the ceiling and the floor allow optimal sunlight to enter the structure, while providing a playful peak at what’s “underneath the stage,” as described by the architects. + META-Project Via Archinect Photography by Su Shengliang

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

Comments Off on 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.
