Energy Policy and Regulation as an Incentive for Internationalization
Politics is the art of the feasible. Energy Policy certainly follows the same rule. Setting an energy policy is a tough exercise of selecting one among endless options by wisely combining the following three key independent aspects: 1) Energy Security, 2) Economic Efficiency, 3) Environment Efficiency. These three options constitute the three main pillars in the European Union Energy Policy and so forth in all 27 state members.
Trends in public subsidies and incentives around the solar industry in the world
Miguel Pérez de Lema
The international experts say that attempting to accelerate a transition to a low-carbon economy is expensive and risky. Policymakers need to realize that achieving a transition with governmentaided commercialization programs will require putting billions of taxpayer dollars at risk, often in a high-profile way.
Interview: Winfried Hoffmann, President of the European Photovoltaic Industry Association (EPIA)
“Before the end of this decade PV will offer every European citizen the chance to become a prosumer”.
Interview: RaĂşl Calleja, Manager of MATELEC, the International Trade Fair for the Electrical and Electronics Industry
“We want to position MATELEC within the International Trade Fair Calendar”.
A PV giant alongside the Alps
The Curbans photovoltaic power facility has a total output of 33 MWp with approximately 145,000 photovoltaic panels producing 43,5 million kilowatt hours of renewable energy each year. This is equivalent to the annual electricity consumption of 14,500 households (excluding heating) and, compared with a fuel oil power plant, sparing close to 120, 000 metric tons of CO2 emissions annually. The plant, with an investment of 100 million Euros led by the French giant GDF SUEZ, has been fully executed as an EPC by the Spanish engineering company Maetel, a company belonging to the ACS Group’s industrial division, and it is currently the highest capacity facility built in France.
India: Opportunities and challenges in PV projects and manufacturing
India’s rapidly expanding solar power market represents a wealth of potential opportunities for home grown and foreign PV manufacturers and project developers. It is not all plain sailing, though; like any emerging market, the Indian PV sector has its share of growing pains.
State of energy: South Africa’s Sustainable Energy Situation
Compared to developed countries in Europe and North America, South Africa’s sustainable and renewable energy sector is under-developed. This is the opinion of SESSA acting-CEO, Theo Covary. While South Africa experiences some of the highest levels of solar radiation in the world at anything between 4.5 kWh/m2 and 6.5 kWh/m2 (parts of Europe receive only 2.5 KWh/m2), 90% of its electricity is from coal-fired power stations, ranking it in the top 15 global polluters.
Solar power in the UAE
Adrian Wood
On a per capita basis, UAE residents consume more electricity than almost anyone else on the planet – certainly much more than people in Europe, Asia or North America. Alarmingly, our consumption is climbing higher and higher. In 2011, peak electricity demand in Abu Dhabi grew by almost 14%, one of the highest in the world. And according to official government forecasts, demand is expected to continue growing by over 10% until at least 2019.
Energy Storage Systems integration into PV Power Plants
New challenges are growing currently in the field of operation of electrical power system, which includes the increasing level of distributed generation from new energy sources, especially renewable sources. Energy storage will soon become a key element of smart grids, especially as more power generation from inherently intermittent sources such as solar and wind come online.
The path to your own power distribution grid
Off-grid systems on AC basis open up new possibilities for providing a stable and powerful energy supply independent of the power distribution grid. This kind of stand-alone network not only provides the customary supply quality usually associated with power distribution grids. Due to its modular structure, it is also very simple to install and can be expanded freely. Through the integration of renewable energy sources which avoid fuel costs and are steadily becoming more economically viable, such systems are today already more cost-effective than conventional systems running on diesel generators.
Rural PV micro-grid with individual energy allowance scheme powers a 60 homes village in Santo AntĂŁo (Cabo Verde)
The 60-family community of Monte Trigo, a village in the Cape Verdean island of Santo Antão, is only reachable by boat and is completely dependent on fishing and its trade with nearby villages. The need for ice to preserve fish is vital, and villagers have frequent five-hour boat trips to purchase it. It was to respond to this need that local entities, with the support of the ACP-EU Energy Facility programme, came together to finance and develop an off-grid solar energy project that consists of a rural Multi-user Solar micro-Grid (MSG) based on a photovoltaic generator mounted on a special wooden pergola that also provides shade to the village’s schoolyard.
Arcs in Photovoltaics
Over the last few years, the number of PV system installations has grown enormously in certain parts of the world. As a result, safety and quality standards have been continuously updated in order to ensure that today’s systems are as safe and reliable as possible. It is vital that these standards continue to evolve and that any potential system weaknesses continue to be identified and resolved. One current topic of discussion is the occurrence of arcs in PV systems and the ways to eliminate this risk. Read on to find out more...
New technologies for the management of renewable assets
The introduction of new technologies to Renewable asset management is already underway. These systems named Asset management systems (AMS) or Assets intelligence systems are changing rapidly the way of doing business in the renewable energy sector.
Solar so good
In a relatively short time the small PV systems of only a few watts have developed first to a few kilowatts and more recently to as large as 10MW. During this time a number of key changes have occurred to the topography and dimensions of the basic components and indeed the types of components themselves, especially those whose primary function is overcurrent protection.
International harmonization of standards for solar thermal collectors
Alberto García de Jalón, Marcelino Sánchez
The testing and characterization procedures for solar thermal (ST) collectors and components have been investigated since the beginning of the International Energy Agency (IEA) Solar Heating & Cooling Programme (SHC). Since then, the developed performance tests and short-term tests to predict long term durability have been mainly focused on low temperature collectors, like flat plate and evacuated tube, under well-defined standard test conditions.
TRESERT – Sustainable concept of decentralized clean energy supply in South East Asia
The project demonstrates how a decentralized supply of electrical energy, heat and refrigeration can be created from solar thermal energy and biomass.
