Kyocera. A trio of KD Series solar modules uses a larger and more powerful solar cell to deliver a higher output per module and achieve an STC maximum power rating of 135 to 205 W, depending on the model, says the firm. The MyGen Grid-tie Photovoltaic Power System offers a complete package of modules, inverter, wire and lightning protection, and mounting and mechanical support that hastens installation and meets most code and utility requirements. 800.223.9580. www.kyocerasolar.com.
Evergreen Solar. ES-Series poly-crystalline solar panels feature String Ribbon wafer technology. The panel’s design consists of 108 poly-crystalline silicon solar cells, anti-reflective tempered solar glass, EVA encapsulant, polymer backskin, and a double-walled anodized aluminum frame. Each panel measures 371/2 by 61.8 inches and weighs 40.1 pounds. Three panel options achieve an STC maximum power rating of 180 to 195 W; multiple mounting options enable installation versatility. 508.357.2221. www.evergreensolar.com.
Ready Solar. The Solar in a Box system is a factory-assembled, 2-kW standardized solution for residential applications. Each racking system accommodates a PV module measuring 10 by 6 feet to deliver 0.5 kWh of electricity. The turnkey solution (including modules from one of several manufacturers) consists of panels, an inverter, mounting system and hardware, and roof jacks and flashing. The homeowner can monitor the system’s performance online, and battery backup is available as an optional upgrade. 877.817.3239. www.readysolar.com.
Luma Resources. This residential roof-mounted solar kit, invented by a roofing contractor, uses thin-film PV technology and consists of 60 solar shingles, a DC-AC inverter, and all flashing and fastening components. Each interlocking shingle measures 51.125 by 15.625 inches and achieves an STC maximum power rating of 31 W. The system is designed to integrate with common horizontal roof shingle layouts. 888.733.5862. www.lumaresources.com.
EcoTechnologies. PVL-136 FlexLight is a flexible, lightweight, laminate PV panel that adheres directly to the roof finish without nullifying the roof’s warranty. The panel’s laminated design captures the complete solar spectrum more efficiently than traditional systems, says the manufacturer, to produce more electricity per watt; the top layer minimizes power loss when the panel is shaded. Each panel measures 216 by 151/2 inches, achieves an STC maximum power rating of 136 W, and is code-approved for use in Miami-Dade County, Fla. 888.522.3626. www.ecotechnousa.com.
Sanyo. HIT Series photovoltaic panels for residential, grid-connected systems feature a proprietary hybrid of single crystalline silicon surrounded by ultra-thin, amorphous silicon layers to reach greater cell and module efficiencies. Panels measure 51.2 by 35.2 inches, achieve an STC maximum power rating of 180 to 205 W, and boast conversion efficiencies up to 17.4%. Bifacial models also generate electricity from ambient light that has passed through the panel or is reflected off surrounding surfaces. 469.362.5645. www.us.sanyo.com/solar.
Fronius. Grid-tied (utility interactive) photovoltaic panel DC-to-AC inverters use a high-frequency design to deliver higher reliability and performance at a reduced size, weight, and installation cost. The inverters accommodate crystalline, poly, or thin-film solar cell technology, and they lock onto the array’s maximum power point to optimize the energy output. The units actively and automatically cool to maintain efficient operation and maximize switching efficiency. Large LCD displays enable easy monitoring of several functions and performance. 810.220.4414. www3.fronius.com.
PV Powered. PVP series DC-to-AC grid-tied (utility interactive) PV system inverters provide maximum energy harvest for residential-scaled installations. Compatible with common solar cell technologies, the inverters may let homeowners expand their PV systems over time. The units are available in extended and standard voltage range versions to accommodate next-generation and traditional modules. Units offer a code-compliant integration platform for both indoor and outdoor installations, and site-specific configurations that reduce permitting and inspection issues and reduce installation time. 541.312.3832. www.pvpowered.com.
SMA. Sunny Boy DC-to-AC grid-tied (utility interactive) inverters are designed for use with almost any type of PV system as well as other alternative energy options, including wind technologies. Units employ an optimized, active cooling concept and rugged cast-aluminum housings that make them ideal for outdoor installations. The inverter’s peak-power-point tracker results in maximum energy capture and a high electricity yield. Series consists of more than a dozen models designed for the U.S. solar market. 916.625.0870. www.sma-america.com.
