How would you like to buy a solar electric (photovoltaic) system for your home or business, and cut the payback time almost in half? PV/T (photovoltaic thermal) systems may offer a way to improve solar payback times by capturing the waste heat energy from the Photovoltaic (PV) system for your building’s water and space heating needs. Of the sun’s energy that falls on the PV modules, about 15% is converted to useful electricity, which leaves 85% of the sun’s energy available as heat. This excess heating of the PV module is wasted and also decreases PV module efficiency.
Frank Asbeck, SolarWorld's chief executive, spoke with workers and board members in Hillsboro during a visit earlier this month. The German company has invested more than $500 million in its Hillsboro plant, built originally by Japan’s Komatsu as a semiconductor wafer factory. Nearly 1,000 people now work in the plant
Spire Solar recently won a contract with Federal Prison Industries (FPI) to install photovoltaic module systems for UNICOR, FPI’s inmate employment division. The contract is on an Indefinite Delivery, Indefinite Quantity (IDIQ) basis for the engineering, procurement and construction (EPC) work on systems for UNICOR
Preservationists say case-by-case reviews of residential solar installations within historic and conservation districts are necessary to maintain neighborhoods' characters. Solar hot-water panels are visible on this home within the Piedmont Conservation District, but the addition of solar panels would require review
Harvesting energy from the sun is hardly a new idea, but in the past year Pendleton has seen a marked increase in solarized homes, thanks in large part to a push by the city of Pendleton to promote solar power.
The goal for the pilot program: Solar energy for 50 new homes by Aug. 31. Four months later, Solar Beaverton didn't quite hit its goal of 50 -- 45 homes signed contracts, with a few others still in negotiations -- but city officials who sponsored the project say they're pleased with the results nonetheless.
With a background in green building and community development, James Santana has been a part of the Pringle Creek development team since the property was purchased in 2005, helping plan and design Oregon’s first LEED Platinum home, the Pringle Creek cottage; and Painters Hall, Oregon’s first LEED Platinum net-zero-energy commercial building.
A code developed by the Oregon Building Codes Division will establish requirements for installing photovoltaic systems. But the code would limit which parts a solar installer could use to attach solar panels to roofs. That doesn’t sit well with solar installers, solar manufacturers or the people in charge of writing the code.
