SR20 is a solar radiation sensor of the highest category in the ISO 9060 classification system: secondary standard. SR20 pyranometer is designed for PV system performance monitoring and scientific meteorological observations. It was released February 2013 after a thorough program of acceptance tests
Alta Devices today disclosed that it has reached 30.8% solar cell efficiency. This new NREL (National Renewable Energy Laboratory) verified record has resulted from the company's first implementation of a new generation "dual junction" solar cell technology which augments the company's "single junction" technology. Higher efficiency directly translates into more electricity generated from smaller surface areas. Therefore, applying Alta's highly efficient, very thin and flexible mobile power technology to consumer devices can extend the battery life of everyday products such as smartphones, tablets, keyboards, mice, remote controls, and more. "We are changing the way solar technology is used," said Chris Norris, president and CEO of Alta Devices. "With our technology, enough energy can be generated from sunlight to effectively power devices in ways not previously possible. We are working with a number of customers who are designing their mobile products to increase battery life; and in some cases, we can provide enough energy to eliminate the need to plug into the electric grid."
Ballard Power Systems has announced signing of a definitive agreement with Anglo American Platinum Limited.
The continued accumulation of solar project portfolios drove much of the M&A activity in 2012, as transaction activity was strongest among targets categorized as producers of solar energy and EPC integrators/developers.
As a result, of being in this higher risk environment we have to think defensively and make sure to protect some of these incredible profits.
I live in the middle of the woods out in the country in Ohio; far enough out where there is no cable service, no gas, no piped-in water, no sewers, cell phones don't work, the grid provides reasonable power most of the time, and the one analog-POTs telephone line works if there is not too much water in the crick.
Many homeowners want security and protection in case the grid goes down, and battery backup systems are a great solution to bring this peace of mind.
In Part 1 we examined the energy bank, and the loads upon it. Next, we will explore some of the energy harvesting needs and capabilities.
Three months of experimental validation allowed us to refine the technique to the point we could pursue grant funding from the National Science Foundation (NSF) Small Business Innovation Research (SBIR) program and submit a provisional patent application.
Over the past few years we've seen a real interest from schools, commercial sites, and homeowners. Local and federal governments are also seeing the benefit in on-site energy generation.
The platform uses unique social media, gamification and other features to drive engagement, uses automatic rebate submissions, vendor marketplaces and other features to make taking action easy, and has functionality to cover the full breadth of utility engagement programs (web portals, out-bound messaging, field staff ops., reporting, etc.).
Unique, global risks—whether a disastrous tsunami, puzzling regulations or unpredictable foreign travel mishaps—are a formidable reality as the clean tech industry continues to expand. Awareness of these risks and working with partners that can offer proactive guidance and cost-effective risk transfer solutions can help ensure the industry's continued success.
Schletter and Strata Solar reach agreement for 100 MW (installed PV capacity) of solar mounting systems for 2013
Envelope for Green Buildings • Participation from more than 70 exhibitors and around 5,000 visitors • Special session by Prof Dr. Werner Lang, Technical University of Munich • Construction industry expected to grow by 20 per cent annually
The United Kingdom (UK) has set high targets for the development of offshore wind farms. Sceptics have claimed that such targets are unobtainable, but with the current investments being made and deals being signed within the UK, the future looks to be brighter than previously thought.
