REPOWERING, in general, can be defined as the set of changes aimed at increasing the power and therefore also increase the energy yield. The convenience of the repowering is in the benefits of technological modernization, which provides solutions for higher power and performance as the technology matures.
This article reviews the recent history of PV monitoring; the shift from single-meter systems to module-level control using highly reliable electronics, and future direction of the industry towards active system management from utility-scale solar farms down to the residential PV system.
One solar PV innovation has largely flown under the radar: pole mounted solar electric panels. That is, mounting solar PV panels on a steel pole anchored in cement, fully capable of adjusting to daily and seasonal sun positions.
Constructing a solar-powered light in a jar is a great project to do with kids. It can be done at home, or in a classroom, with simple materials, and will serve to give them a good understanding of how solar energy is used.

He spent 20 years in various operating management positions in the industry, beginning with Honeywell and culminating as CEO of publicly traded EFTC (now part of Suntron). Jack is a frequent speaker at industry events and oversees Lincoln's publications in the EMS, Power and Solar Energy industries.
Solar PV expert and consultant Kyung Nam Kim, author of the report "The Korean PV Market", is optimistic about his country's solar future. His report provides a unique and comprehensive overview of Korea's PV market and industry, and it is available in English. It includes a detailed description of the market situation, forecasts, regulatory procedures, and a detailed overview of Korea's PV supply chain.
XsunX is combining its thin-film photovoltaic (TFPV) process knowledge and processes with magnetic media thin-film manufacturing technologies used by the hard disc drive industry to mass produce high efficiency, low cost solar cells. Current techniques for the production of CIGS thin-films do not leverage stationary small area, high rate, production technologies which allow for the precise control of thin-film properties.
According to a new poll from Droege & Comp. and Gibbs & Soell, U.S. Solar businesses are poised for strong growth in 2010 and significant growth in 2011. However, respondents indicate that obstacles still remain. Favorable legislation, customer knowledge and heightened marketing will be keys to the expansion of their business. Participants included nearly 100 professionals representing key areas of the solar business value chain. Results from the 2009 Solar Industry Monitor were unveiled at the 2009 Solar Power International Show in Anaheim, Calif.
Interview with Federico Brucciani, independent solar PV expert and author of the report "The Italian PV market". Brucciani is very optimistic about market growth in his country. He says that grid-parity will be reached in all market segments within the next 6 to 8 years. He adds that the market is becoming more sustainable than in Spain and that a new and appealing FiT program can be expected as a follow up to the current program, which has met with so much success.
With Presidential direction and Congressional support, NASA's wellspring of talent could help foster the creation of solar power satellites - spacecraft that circle the Earth and beam the energy they generate down to the ground for distribution as electricity.
As the PV business continues to grow, new backsheet constructions are continually being introduced. But the products we use in our efforts to be more sustainable have a bigger footprint than we think. Currently, there are at least ten commercial manufacturers of traditional PV backsheets, with traditional products in the development stage. Traditional backsheets, the protective covering on solar cells, are produced mainly from polyester and Tedlar films. Polyester is made from petroleum and Tedlar is solvent-cast using DMAC, a highly toxic industrial solvent. Both of these products defeat the purpose of clean, green energy, and as the demand for solar energy increases, so does this issue.
Over the past 10 years, Sheila Davis has played a valuable role at SVTC and in shaping environmental policy in the high-tech industry. She is one of the co-founders of the Computer TakeBack Campaign and sits on its steering committee. In 1996 she researched and developed the first electronic recycling legislation to reach the California Governor's desk and in 1999 spearheaded the first pilot programs in the country to collect and recycle electronic waste from the residential curbside.
In 2007, and during the first half of 2008, all the signs for PV were positive. There was a very attractive feed-in tariff in Spain, credit lines were easy to get, oil prices were rising and economies growing rapidly. Now, the industry faces a strong head wind with oil prices very low, economies in recession, finance hard to obtain and the world's largest market regulated by a cap with a 30% lower feed-in tariff.
India, the world's second-most populous country, is facing a looming energy crisis. Soaring oil prices, and continued dependence on a few countries for oil, has led to the use of renewable energy sources to secure energy.
Federal and state rebates can save you as much as 50% on your total cost, so it is important the company is taking every advantage of available rebates.

The Darfon G320 is the microinverter solution for today's high-power solar modules. The G320 handles 60- and 72-cell modules up to 350W DC and outputs up to 300W AC. The G320's 3-phase configuration accommodates the electrical distribution systems of most commercial buildings and to reduce, if not eliminate, the need for expensive transformers. The G320 comes in four voltage/phase configurations, so it can be installed in residential, commercial or utility applications.
