A grid-interactive PV system implies that a PV system is tied to the grid but can stand alone if the grid goes down. Essentially, it offers the best of both off-grid and grid-tied systems.
This new type of architecture has inherent cost and reliability advantages over microinverters: it uses fewer critical components than microinverters, its easy installation and connection to the grid allows for reduced installation and maintenance costs and its connection to the module at a cellular level means the performance and cost of the solar module can be optimized.
Making affordable financing options available to as many people as possible is the key to stimulating widespread adoption of residential solar. That's why Clean Power Finance offers affordable financing options for qualified installers and homeowners as well as our CPF Tools residential solar sales platform to simplify, streamline and speed up the permitting process.
Caught between strong utility-scale project demand, declining solar incentives in distributed generation applications, module over-supply, and significant policy uncertainty, the North American photovoltaic (PV) market is at a crossroads, according to the conclusions of the recently-released NPD Solarbuzz North America PV Markets Quarterly report.
Wind Power - Global Market Size, Turbine Market Share, Installation Prices, Regulations & Investment
Consolidation is on the cards as the US market is undergoing correction and the Chinese wind market is expected to stabilize during the forecast period. Companies have modest expectations of growth for 2011 as major markets have slowed down but are expected to pick up in the second half of year.
We have a long way to go before AV, lighting, HVAC, and appliances come together within a home automation network that will work with smart meters and the utilities' back office system to communicate both ways flawlessly, controlling how and when energy is wisely consumed. Strides are being made in each area and we will see more systems coming together for the perfect balance of energy consumption and energy savings.
The roadmap for biomass is under study in China and may prove a gem for development of the sector. Biomass presently contributes nearly 5% of power generation to the total renewable. The technology has good growth prospects due to available potential in the country.
The prospect of a probable reduction in nuclear in France presents a fantastic opportunity for the photovoltaic industry. And never mind the Chinese competition - the French players have their card to play.
While startup costs and transition problems have yet to be resolved, Germany is betting on its future, and future generations using solar and wind power will not have to bury energy wastes with a half-life of tens of thousands of years.

The South Africa Baviaanspoort site has yielded significant savings in terms of maintenance and repair costs and improved reliability over the duration that the ElectraGen™ ME has been installed.
The European wind energy market is just starting to recover from the economic downturn in 2009. As demand stabilises, steady growth is forecast. At the same time, the market is poised for greater consolidation that will result in the emergence of fewer but stronger participants. New analysis from Frost & Sullivan (http://www.energy.frost.com), European Wind Energy Markets, finds that the market earned revenue of $19.18 billion in 2010 and estimates this to reach $42.48 billion in 2017. The application sectors covered in this research service are offshore and onshore wind energy. "Europe's wind energy market is primarily driven by the European Union's renewable energy agenda to meet 20 per cent of its energy needs through renewable sources by 2020," notes Frost & Sullivan Research Analyst Neelam Patil. "The high growth potential of offshore wind energy, coupled with the emerging markets of Central and Eastern Europe (CEE) are attracting investments in the European market."
A lack of progress for battery technology is (arguably) the single biggest barrier for gadgets, electric vehicles and the power grid. But there continues to be innovation, like last week researchers at Northwestern University unveiled technology that can boost gadget battery life by ten and charge a battery in minutes instead of hours. And there’s hundreds of researchers, entrepreneurs, universities and large companies working on battery breakthroughs. Here’s 25 you should know about:
Ascent Solar Technologies, Inc. a developer of lightweight, flexible, thin-film photovoltaic modules, announced today that itsflexible CIGS solar panels were named one of TIME's 50 Best Inventions of 2011. Ascent's technology was one of six ‘green' inventions to be recognized in this year's list, featured in the Nov. 28 TIME issue. For each of the past 10 years, TIME has recognized the top 50 breakthroughs in science, technology and the arts. Previous honorees have included the iPad, Nissan Leaf, 3-D cameras, and the world's first synthetic cells. "We are honored to be recognized by TIME as one of this year's top 50 inventions," said Ascent Solar President and CEO, Ron Eller. "Our flexible solar panels integrate seamlessly with countless applications across a wide variety of markets. TIME's recognition further validates the transformational aspects of Ascent's technology."
Twenty-one cleantech startups from across the U.S. competed for a grand prize of $250,000 in seed investment and services at this year’s Cleantech Open Business Competition. On Wednesday night, the not-for-profit organization awarded the national grand prize to the winner in the renewable energy category, Atmosphere Recovery, which makes laser-based gas analyzer systems for efficient manufacturing and advanced energy process control.
