Digital Inkjet Printing: An Opportunity for Further Reductions in Solar Energy Costs

With solar on the cusp of economic feasibility in many areas, incremental cost reductions such as those offered by digital inkjet printing technologies can make the difference between moving ahead with solar and sticking with electricity from the local utility

Start of test with solar energy generating noise barriers alongside highway

Alongside the A2 highway near Den Bosch, The Netherlands, two test noise barriers are installed that generate solar energy. The aim of this practical test, that was officially launched 18 June is to assess the economic and technical feasibility of this form of energy generating noise barriers. Playing a key role in the test are the LSC panels, developed by researcher Michael Debije at TU/e. The translucent, colored panels are a new type of energy source, developed jointly by TU/e. These 'luminescent solar concentrators' (LSCs) receive sun light and guide it to the side of the panels. There, it lands in concentrated form on traditional solar cells. "Thanks to their many colors the LSC are visually very attractive, which makes them ideal for use in many different situations in the built environment", explains Debije of the Department of Chemical Engineering and Chemistry, who has carried out years of research into these panels. "Further benefits are that the principle used is low cost, they can be produced in any desired, regular color, is robust, and the LSCs will even work when the sky is cloudy. That means it offers tremendous potential." Debije published his latest research findings on this subject last March in Nature. On 18 June a one-year practical test started in 's-Hertogenbosch, led by the building company Heijmans. The researchers intend to assess the feasibility of generating electricity using solar cells integrated in noise barriers or SONOBs (Solar Noise Barriers).   Cont'd...

Is Adding Solar Batteries Worth it?

Seeking to help states better address the value proposition of solar+storage systems, the Interstate Renewable Energy Council, Inc. (IREC) engaged Clean Power Research (CPR) to develop a methodology that could be used to value solar energy coupled with battery storage. The methodology described in the report can be applied in any location. It focuses on Hawaii as an example, as it is likely to be an early adopter of storage regulations.  "The concept of adding batteries alongside a utility customer's solar array intrigues utility customers, solar developers, and utility planners on several levels, but the underlying question for everyone is whether adding batteries is 'worth it,'" says Jason Keyes, Partner at Keyes, Fox & Wiedman LLP, attorney for IREC and report collaborator.  Though still at a nascent stage, the recent rapid growth in the distributed energy storage market suggests that now is an opportune time to take a closer look at distributed energy storage, especially in combination with distributed solar, and the values it has to offer. The new IREC study lays out the methodology to do just that and sets forth a pathway for more robust analysis and dialogue.   Cont'd...

Investment In Renewable Energy Yields More Jobs Than Fossil Fuel Sector

Joshua S Hill for CleanTechnica:  A new report has determined that investments in energy-efficient and renewable energy sources yield more jobs for a set amount of spending than investing in maintaining or expanding the fossil fuel industry. [wind turbine cowboy jobs] The report, Global Green Growth: Clean Energy Industrial Investment and Expanding Job Opportunities, was published earlier this week and presented at the Vienna Energy Forum 2015 by its two authors, the Global Green Growth Institute (GGGI) and the United Nations Industrial Development Organization (UNIDO). “Significant progress has already been made in overcoming the hitherto conventional wisdom that taking steps to cut GHGs is incompatible with economic growth,” said Yvo de Boer, Director-General of GGGI. “This report moves the debate another positive step forward by showing that employment and development result from sustainable, green growth.”

Trina Solar to Invest $500 Million in India-Based Solar Plant

Per a media report, Trina Solar Limited is going to invest $500 million for building a 2-gigawatt solar module plant in India in partnership with Welspun Energy Ltd. The plant's output will be exported to the U.S. and European markets, which have imposed punitive trade duties on solar shipments from China.  The facility will be built in either Gujarat or Andhra Pradesh. Construction of the plant will be completed in two phases over a period of about 18 months.

Why You Should Be Paying Attention To The 'Other' Form Of Solar Power

Joe Romm for ThinkProgress:  Solar photovoltaic (PV) systems have seen explosive growth because of their stunning 99 percent price drop in the past quarter century. As a result, the other form of solar power — concentrating solar thermal power (CSP) — is a small fraction of the solar market. But the International Energy Agency (IEA) says CSP has a very bright future too because it enables cheap, efficient storage, which allows CSP plants to provide electricity long after the sun has set. According to the IEA’s 2014 CSP Technology Roadmap, 11 percent of global electricity will be generated by concentrating solar thermal power in 2050.   Cont'd...
