PV-Thermal hybrids have recently become popular because these systems make more effective use of valuable solar roof space. The Hybrid collector effectively more than doubles the per square foot power output of PV alone. This is done by producing heat for hot water or space heating as a byproduct, in effect, a solar co-generation process. On its own, Solar Thermal usually produces over 4 times the energy of PV in thermal terms. A thermal collector covered with PV is going to work at lower efficiency because most of the direct sunlight is blocked by the cells. If the thermal portion of the Hybrid collector was working at only 25% efficiency, the gross energy output would be doubled. Now add to that increased PV panel efficiency and decreased cooling load and you have a real winning combination. Read more about this idea.
The global solar energy market in 2008 is expected to grow by 50% compared to 2007. The Chinese solar PV industry is growing rapidly and will soon be the biggest producer of solar cells and modules in the world.

For homeowners interested in reducing their personal carbon footprint through solar power but wanting to start off on a smaller scale than a whole-house option, an exciting, energy-saving solution will be available soon from heating and air conditioning leader Lennox Industries. Expected to be available in 2009, Lennox' new SunSource™ system is the industry's first integrated, solar-assisted residential heating and cooling system - and it uses just a single 190-watt solar panel. Featuring a patent-pending design, the innovative system is currently in full operation at multiple test sites throughout the country. The single 190-watt solar panel provides power to assist the fan motor that moves air across the outdoor coil, a key part of any home comfort system. Read more.

In a typical household, over 12 percent of the power bill goes on the small amounts of power consumed by devices in standby mode. Are you a gamer? Well ratchet that figure up considerably further. TrickleStar have a device to save that waste. The TrickleStar™ Universal Standby Power Saver reduces the standby energy consumed by PC and TV Peripheral equipment. The product has inbuilt current sensing circuitry to sense when a PC or TV is on or Off. When the PC or TV is on the product will switch On all peripheral devices. Conversely when the PC or TV is Off, the product will switch Off all peripheral devices. The product is easy to install and provides simple automation to reduce wasteful standby energy consumption.

The Power Electronics team from Swansea University's School of Engineering has developed one of the world's most advanced Smart Electricity Meters. The Smart Meter is to be the focal point for a consumer's personal energy queries. It monitors their energy consumption, giving information not just through a traditional power reading, but in a user-friendly way by displaying animated graphics of money on a large clear screen on the meter. It also goes one step further than most other potential Smart Meters in that it monitors individual power circuits in the home, including upstairs lighting, downstairs lighting and kitchen sockets. The team believes there is also the possibility to monitor individual appliances when the technology is adopted further. The presentation of consumption information is complemented by the ability to show power generated from micro-renewable technologies in a 'plug and play' manner, similar to the wind turbine currently commercially available, and generic solar panels. This is an effort to provide a simple, easy to set up method for people with no expertise in Power Electronics. Read more .
