The George R. Brown Convention Center

The George R. Brown Convention Center (GRB) Solar Pilot Program, managed by the Houston Advanced Research Center (HARC) is part of the Solar Houston Initiative (SHI), a Department of Energy (DOE) Solar America Cities (SAC) program. The DOE SAC program is a federal program to accelerate the adoption of solar energy technologies for a cleaner, more secure energy future. Sponsorship and funding for the GRB Solar Pilot Program was provided by the City of Houston, GRB, HARC, Houston Endowment Inc., Standard Renewable Energy (SRE), The American Institute of Architects, Houston Architecture Foundation, BP and CenterPoint Energy.

The system consists of  51.3 kW DC STC crystalline module array  and a 49.0 kW DC STC amorphous thin film array. The crystalline module array consists of 270 BP modules, rated at 190 watt (W) DC STC, located on the I-beam along the south side of the building, mounted on supports painted to match the color of the existing beams. The amorphous silicon (a-Si) thin film array consists of 360 Uni-Solar Photovoltaic (PV) flexible thin film panels, rated at 136 W DC STC, installed on the southern portion of the GRB roof adhered with Green Lock membrane adhesive. Each array is connected to a Satcon Photovoltaic PowerGate Plus 50 kW 480V 3ph 60Hz Nema 3R inverter system (Model # PVS-50-4UL-10 Years). The inverters are connected to the building’s electrical distribution system.

New kind of 'tandem' solar cell: Two types of photovoltaic material combined to make a cell that harnesses more sunlight
Researchers have developed a new kind of solar cell that combines two different layers of sunlight-absorbing material in order to harvest a broader range of the sun's energy. The development could lead to photovoltaic cells that are more efficient than those currently used in solar-power installations, the researchers say.
