“Complete Solar Roof” Offers Power and Heat

“Complete Solar Roof” Offers Power and Heat

The Complete Solar Roof by Solarcentury of England offers an alternative to conventional roofing products by combining solar electric and solar thermal in a tile that is installed like a conventional roofing tile. The two technologies are integrated to generate both power and heat from sunlight. The tiles sit flush with the building's roof structure. The Complete Solar Roof is part of Solarcentury's line of Low Carbon Building Products, which aim to integrate solar energy into standard construction practices.

Translucent Roof’s Properties Prove Efficient and Durable

Translucent Roof’s Properties Prove Efficient and Durable

A translucent patent-pending roofing structure allows natural, filtered daylight to penetrate living areas without the energy loss and higher heating and cooling costs associated with ordinary glass roofing inserts. Centerpoint's roofing system, said to offer "museum-quality light into your home," does not compromise in strength or durability. The selection of the new pre-assembled roofing system, according to the company, was based on the product's excellent light transmission; the ability to withstand wind loads of up to 140 mph; superior UV resistance and impact strength; lighter weight and design flexibility than glass; and exceptional sound and energy insulation. The translucent roofing system is also appropriate for roof domes, skylights, walkways, conservatories, and other building applications that need high levels of light while keeping excess heat to a minimum. Company PR follows.
Navy Completes Solar Energy Project in Hawaii

Navy Completes Solar Energy Project in Hawaii

The Hawaiian Islands' abundant sunshine but heavy reliance on imported fuels for energy puts it in a particularly good position to take advantage of solar energy. This week marked the completion of a 309 kW solar array at a US Naval facility, the largest federal deployment of solar energy on the islands.
Landmark Solar Project Takes Cues from Nature

Landmark Solar Project Takes Cues from Nature

One of the most unusual sustainable buildings in the world, designed on nature's architecture and generating energy from daylight, was launched last week in a light show at the Eden Project in Cornwall. True to the Eden Project's principles, the new education and research facility, named The Core, is a superb example of sustainability using building-integrated photovoltaics (PV).
Energy-Efficient Vs Traditional Homes: 4 Strategies for a High-Performance Home

Energy-Efficient Vs Traditional Homes: 4 Strategies for a High-Performance Home

New England has experienced one of the most intense winters in recent history. Relentless snow hampers travel, winter weather advisories are frequent, and huge snow drifts obscure cars. Such weather makes me grateful to live in a high performance house in Belfast Ecovillage, a 36-unit community built to the Passive House standard (but not certified) in Mid-coast Maine. While neighbors in our cold […]
A New Competitive Landscape for Solar PV Racking

A New Competitive Landscape for Solar PV Racking

I've been attending the Intersolar conference in San Francisco for ten years since it was just Semicon, and noticed many of the most interesting trends don't show up in the headlines. This year, I noticed that the exhibit halls were packed with metal (racking) peddlers, far more than in previous years.

Oregon Pepsi Cola Plant Unveils 172 kW Solar Project

It all started when Pepsi Cola General Manager John Bocchi decided to improve the energy efficiency of the lighting systems at one of the company's facilities in Klamath Falls. Instead of simply changing over to more efficient light bulbs, the company installed a 172 kW solar electric system at three separate locations. The system should generate all of the energy that the facilities will use over the course of a year.
