Free solar for Africa?
The African continent is not homogeneous. The constant gap between the way we perceive the north of the continent and the harsh reality that the South is going through is often surprising. Many start to see and praise the "African miracle” progresses. However, many obstacles remain for Africa to impose its way. The sun, is a natural, free and abundant wealth in the African land, would it ...

Solar Inverter versus Regular Inverter
Difference between a Solar Inverter and a Regular Inverter Something that is often asked is what exactly is a solar inverter and how does it differ from a regular inverter we use ...

CSP Thermal Energy Storage vital for utilities and grid operators
The modern age of CSP can arguably be traced back to the 354MW Solar Energy Generating Systems (SEGS) in the Mojave desert, which now make up the oldest operating plant in the world, as well as one of the largest. However, recent developments in the industry will see SEGS eclipsed by 5 projects that are scheduled to come online in 2013-14, with a combined total of 1312MW. The five plants in ...

Micro Power to the People
A letter to the editor alerted me to my chance to finally see a microhydro system. On January 18, Vivian Stockman and I visited Mickey and Jennifer Janowski, who live at an elevation of 2,250 feet in Webster County, W.Va. We didn’t go to admire their log home, which they built themselves — but we did that, too, while we were there. They’ve had an off-grid solar power system ...

Learning curve proving steep for the Indian CSP industry
Phase 1 of the National Solar Mission aimed to provide India with a learning curve for its first steps into CSP, with recent developments suggesting that there are many lessons to take into the next phase. In a recent interview Tarun Kapoor, Joint Secretary at the Ministry of New and Renewable Energy (MNRE), attributed delays in CSP project development to problems in the supply of critical ...

Asia–Pacific Analysis: The slow road to green energy
More Asia–Pacific countries need to embrace renewable energy and follow the first tentative steps of some governments, says Crispin Maslog. The South-East Asia and Pacific region is blessed with abundant sources of 'green' energy — including sun, wind, water, biomass and geothermal — but governments are still not doing enough to harness them. The 30 countries in this part of ...

MENA set to spearhead Solar developments as CSP & PV grind to a halt in the western world
The solar community in the Western world is undergoing radical change in 2012. Falling PV prices and the ending of the DOE loan guarantees in the US have hit the CSP industry hard, making it difficult to secure the necessary political and financial support to continue development. The PV market is also on the brink of collapse, with damaging effects from government incentive programmes set to ...

How to make energy efficiency affordable
Energy efficiency is a tortoise in the green energy race. Not glamorous like solar, wind or smart grid, it tends to plod along in the back of the pack, attracting little media attention. But being last can be a good thing; you learn from the frontrunners. Such is the case when it comes to financing. EE is beginning to borrow from strategies that have spurred tremendous growth for solar and other ...

How well is clean energy weathering the recession?
The clean energy industry may not be popping the champagne cork, but it is at least holding the bottle in hand. While not unscathed by the recession, the industry sees growth in several sectors, according to recent reports. For example, use of smart meters—a key technology for better energy management and efficiency – is increasing at a rapid clip. A study by ABI Research, “Advanced Metering ...

Artificial neural network based models for forecasting electricity generation of grid connected solar PV power plant
This paper presents an artificial neural network (ANN) approach for forecasting the performance of electric energy generated output from a working 25-kWp grid connected solar PV system and a 100-kWp grid connected PV system installed at Minicoy Island of Union Territory of Lakshadweep Islands. The ANN interpolates among the solar PV generation output and relevant parameters such as solar ...
