SunRun, a leading provider of home solar power announced that the company has received an extra tax investment from a subsidiary unit of US Bancorp. This extra investment is part of the $90 million that is required for the residential solar installations to be carried out in the year 2010. Through this funding, homeowners in various states will be provided with affordable solar energy. US Bancorp has provided this funding after a year of the launching of SunRun’s first residential power purchase agreement.
Bullis School dedicated the largest solar electric power system at a ceremony held at a private school in the DC area. Students, school administrators, federal and state legislators attended the ceremony. This system is owned and operated by Washington Gas Energy Services (WGES). The solar system was installed by Clean Currents Solar and it will provide electricity to Bullis School’s Blair Family Center for the Arts.
The Grundfos SQFlex pump system is capable of functioning at any voltage from 90 to 240V AC and from 30 to 300V DC. It can operate at any voltage without requiring different settings or additional controls. This solar water pump provided by Four Winds Renewable Energy can be operated directly from a battery bank or PV array through DC voltage.
The solar charge controller incorporates battery charge management, MPPT (maximum power point tracking), and charge information and communications, all in one device. The solar charge controller can provide continuous output of 80 amperes. The full rated power can be obtained from the charge controller even at a high ambient temperature of 45 degrees Celsius.
Researchers of Boston College for the very first time have observed “hot electron” effect in a solar cell and the elusive charges have been successfully harvested with the usage of ultra-thin solar cells. This discovery can be utilized for the improvement of solar power efficiency.
LDK Solar announced that it has signed a contract with Enfinity, a Belgium-based company, to supply solar modules. LDK Solar, a top listed manufacturer of solar wafers, made this announcement on 14 December, 2009. An estimated amount of 50 megawatts of solar modules are to be delivered to Enfinity in the year 2010, according to the terms mentioned in the signed contract.
The Soitec Group has acquired Concentrix Solar GmbH, a privately held company, to enter the fast-growing solar energy market. Concentrix Solar is a leading provider of concentrated photovoltaic (CPV) solar systems. Soitec provides engineered substrates to microelectronic companies. Engineered substrates play a vital role in the improvement of solar cell performance and Soitec’s technology is regarded to complement Concentrix’s expertise in CPV systems.
The TSW3224W off-grid true sine wave inverter has 120/240VAC split-phase output and input operation. It requires no external transformers for step-down, step-up or balancing. The output provides 12V for standard circuits and 240V for appliances, well pumps or shop tools. The 200% surge power capacity is available for intermittent loads without disrupting the sensitive computer loads.
The SunWize SW85 solar panel comprises 36 monocrystalline solar cells that are connected in series. The photovoltaic cells are encapsulated in ethylene vinyl acetate layers and laminated at the back with white Tedlar film. This encapsulation protects the solar cells from extreme climatic conditions.
Electricity is now being generated at the recently constructed Loudoun County Homeless Services Center with the help of a 9.5-kilowatt array of solar panels. These solar panels were installed by Standard Solar. This structure with its air-handling systems, passive lighting features and energy efficient appliances, is expected to receive a “Silver” certification from the Leadership in Energy and Environmental Design Green Building Rating System, which is nationally recognized.
