Solar Panels Are Getting Cheaper

The solar industry shakeout continues as rock-bottom solar panel prices have forced a difficult decision at yet another high-tech California solar firm. SolFocus, a San Jose-based manufacturer of concentrating photovoltaic modules, has announced it's looking for a company to buy it after failing to secure new rounds of venture capital investment.

Concentrating PV (CPV) modules are similar to the standard photovoltaic panels you see on more and more rooftops in California, except that CPV uses an optical system -- lenses or mirrors -- to focus extra sunlight on each square inch of photovoltaic surface. CPV systems can reach efficiency levels well above standard PV. As evidence, consider SolFocus' competitors in the sector, Seal Beach-based Amonix, whose modules have reached about 35% efficiency for their commercially available units, and the Bay Area's Solar Junction, which has reached 44% efficiency in the lab. However, the optics needed to focus the sun's light add significantly to the overall cost of a unit. That's a problem when prices of vanilla PV are falling through the floor: CPV just has trouble competing. Amonix itself is an example: the firm closed its Nevada factory earlier this fall.
That said, long-term prospects for the CPV sector appear to be rosier than they are in the short term. Industry analysts at Lux Research forecast growth in the CPV sector that by 2017 will outstrip conventional PV by about 25%. CPV seems to perform better than flat-panel PV in extreme temperatures, such as those encountered in utility-scale desert power stations. CPV may well prove to be the long-term technology of choice for installations in desert cities.
Nonetheless, prospective income from 2017 or later doesn't pay the bills now, and so SolFocus -- which has deployed 15 megawatts of CPV projects in the last two years, and had just announced a new 450 megawatt project across the Mexican border in Tecate -- a project that may get put on hold as the company restructures itself for acquisition. SolFocus has laid off all but a core staff to maintain existing projects and prepare the company for sale, according to a release by the company. Just another day in the continuing bottoming out of the solar PV market.

Solar Vacuum Tube Copper Heat Pipe

Features:1) Higher heat efficiency: Advanced heat transferring style of the heat pipe
Heat transfer speed above the 10, 000 multiple of copper
2) Working without water inner tubes
3) Made of New tr-element vacuum tube .
high pipe copper vacuum tube
different between common vacuum tube and copper heat hipe:1).higher heating efficiency:Heat transferring can be started quickly even under cloudy day. It can work normally even -30 below degree. As no water in the vacuum tube, it can effectively prevent lowing of heating efficiency due to frost cracking or scaling.
2). Each individual tube can work independently, and the whole machine can still work if individual tube is damaged. The service life of the heat pipe can be longer than 15 years.
3). The unique connection between the heat pipe and the vacuum tube can ensure both sealing and replace of damaged glass vacuum tube.

Split Solar Water Heater

Feature:can be put on the inclined roof or flat place. Collector separates with storage tank. The tank can be put in any place of house. And the collector Module design, arbitrary combination, harmony with the building perfectly; Intelligent control and automatic operation; Anti-freeze: No water inside the tubes when it works. The system controller has the anti-freezing function is that the temperature circulation will operate while it reaches the fixed temperature. Multifunction: Bathing, washing, domestic heating etc; Work at anytime and enjoyable. Structure: The split solar water heater is composed by heat collector, storage tank, controller, working station and installation parts. Model No: 100L 150L 200L 300L 400L 500L 600L 800L 1000L
