Optimizing solar thermal performance with data loggers
By measuring and monitoring solar thermal system performance, installers can correct mistakes and fine-tune and optimize systems. As a result, US consumers are likely to regain confidence in the technology, spurring what is expected to be a burgeoning market for solar hot water heaters.
MicroCSP (Concentrated Solar Power)
MicroCSP power projects all include sun tracker and thermal storage. The cost is around the same as PV but you generate more electricity per day because of the tracker/storage combination so you have a lower cost of energy.
Weathering the Storm: Fluoropolymer films protect solar modules and ensure performance
Recent advances in materials science have led to the development of innovative new materials that provide enhanced durability to photovoltaic modules. Unique polymeric thin film technologies, such as ethylene-tetrafluoroethylene (ETFE) frontsheets, provide modules with the protection they need to perform at high levels even when exposed to the elements.
LEED Standards and the Global Carbon Market
Research has shown that LEED buildings consume over 25% less energy, have 13% lower maintenance costs, 27% higher occupant satisfaction and a 33% reduction in GHG emissions compared to the average commercial building.
Case Studies from EarthKind Solar
Bard College and Hawthorne Ridge Retirement Community are two examples of down to earth solar energy projects that make a difference.
Solar Power International 2011 Report
Solar Power International 2011 took place in Dallas, Texas, with a goal to generate powerful new ideas, connections and business opportunities for the solar industry. An estimated 24,000 professionals and over 1200 exhibitors from businesses spanning the entire spectrum of the industry will be on hand for four days of product exploration, discussion, professional enrichment and networking.
The AltEnergyMag team has taken some time to put together a list of some of the interesting new products and services seen at this year's show.
Removing the Rare Element Limitations from Solar Energy
Many of the cutting edge thin-film technologies require rare elements that are a finite resource already in short supply. There simply is not enough material on the planet to make these devices for worldwide consumption.
Understanding Solar Power Purchase Agreements
A Guide to Hosting a Solar Energy System
Under the terms of a solar PPA, a solar services provider installs solar equipment at a host business, government site, university, or other organization, and the host agrees to buy the solar electricity generated by the system for a fixed price and term, usually 5-20 years.
On Energy Management, Manufacturing and Factory Automation
I wrote this article for HomeToys.com, our Home Technology website but it applies to Alternative Energy as well. It's not enough to monitor our energy use. We don't really care about that unless it does something to change our lives or save us money. So, let's put a solar system on the roof. Now that can do both of these things and should attract our attention. But let's take it a step further. With that solar system there is a new variable in the mix --- FREE CLEAN ENERGY. What can and should we do with it.
Don't Forget: NREL are the Good Guys. And so is solar energy.
The Denver recently reported the NREL was going to lay off 10 percent of its employees. It took about two light seconds for a popular Washington D.C. news site to pronounce the layoff a "scandal," because NREL had taken federal stimulus money.
That is silly.
NREL, of course, is where the Department of Energy tests and develops new materials and techniques for solar, wind and other kinds of energy.
Harvesting Energy from Organic Materials
Harvest uses a platform of technologies - including advanced composting, anaerobic digestion, and material recovery - to harness the full carbon, energy and nutrient value from discarded organic materials.
The OPDE Group
OPDE is a Spanish corporation with a global vision that specialises in photovoltaic solar energy systems. We have three business lines. OPDE develops, builds, and carries out maintenance of photovoltaic solar plants; PROINSO supplies modules, inverters, trackers, and other equipments for photovoltaic installations; MECASOLAR specialises in the design and manufacture of solar trackers, fixed structures, and foundation screws.
Q and A about Solyndria and the Clean Energy Industry
In 2009, there were 2.2 million green jobs in America, according to the U.S. Bureau of Labor Statistics. By July of this year, the number was 2.7 million, according to the Brookings Institution. That compares with 375,000 jobs mining coal, producing oil and gas and turning fossil fuels into consumer products.
Lithium-ion batteries for efficient storage of renewable energy and mobile power solutions
Lithium-ion technology is currently more economically and environmentally viable than other existing battery technologies. It will likely be both the present and the future of sustainable storage of renewable energy and mobile power solutions.
Iowa Now Gets 20% of Electricity from Wind
Iowa has led the nation in attracting wind energy manufacturers and building a robust supply chain that supports more than 2,300 jobs and involves over 80 Iowa businesses.

Featured Product
HPS EnduraCoilTM Cast Resin Medium Voltage Transformer
HPS EnduraCoil is a high-performance cast resin transformer designed for many demanding and diverse applications while minimizing both installation and maintenance costs. Coils are formed with mineral-filled epoxy, reinforced with fiberglass and cast to provide complete void-free resin impregnation throughout the entire insulation system. HPS EnduraCoil complies with the new NRCan 2019 and DOE 2016 efficiency regulations and is approved by both UL and CSA standards. It is also seismic qualified per IBC 2012/ASCE 7-10/CBC 2013. Cast resin transformers are self-extinguishing in the unlikely event of fire, environmentally friendly and offer greater resistance to short circuits. HPS also offers wide range of accessories for transformer protection and monitoring requirements.
