The self-consumption of electricity from a photovoltaic system is one of the best solutions to reduce the costs of energy bill. For energy-intensive companies the investment becomes very profitable. The energy bill is usually divided into three components: a variable amount expressed in c€/kWh proportional to energy consumptions a power quota expressed in c€/kW per […]
Industrial rooftop photovoltaic systems can be installed on different types of buildings and bring many benefits to the company that decides to invest in photovoltaic technology. Modularity and wide typology of fastening technologies allow the installation of the PV plant on almost all existing roofs and industrial sheds, including flat roofs, pitched roofs, shed roofs […]
The amount of electricity generated by a sIt is important to understand the project’s purpose and its use case by case.olar photovoltaic panel depends on some factors, such as PV panel technology, dimensions, type of installation, position, location and weather conditions. PV Technology and Efficiency The basic component of every photovoltaic panel is the solar […]
Photovoltaic shelters are sheds covered with photovoltaic panels, used to create protected and shaded areas in spaces such as car parks and/or other parking areas. Enerray, as a leading company in the design, installation and maintenance of industrial photovoltaic systems, is also specialized in the construction of photovoltaic shelters, especially for parking spaces of medium/large size […]
As our communities become more urbanised, our cities need to get smarter to handle in a renewable and sustainable way this large-scale urbanisation to meet citizens’ needs and aspirations for an improved quality of life, reduced pollution, increased efficiency, better services and decreased costs of living. In this context the arab countries are rapidly urbanising, […]
The Shams Dubai initiative, launched by Dubai Electricity and Water Authority (DEWA), encourages households and building owners to install PV panels to generate electricity, and connect them to DEWA’s grid. The electricity is used on site and the surplus is exported to DEWA’s network to be deducted from future energy bills. According to the UAE […]
The Middle East and North Africa (MENA) region is blessed with a quantity of annual sunlight and until recent years it has been more of a liability than an asset, as large areas of the region’s land is too dry for agriculture. As the population continues to grow (in most MENA countries over 50% of […]
The basic component of every photovoltaic system is the solar cell. In most cases the solar photovoltaic cell is made of silicon, a semiconductor that is also used for diodes, transistors and computer chips. With the introduction of foreign atoms (doping) a p-n junction is generated in the cell that “installs” an electrical field in […]
The worldwide requirement for energy is covered today mainly by the fossil fuels: oil, natural gas and coal. But lately, the solar energy technology has been improved: solar cells are six times more efficient today than they were 30 years ago. Solar panels are becoming frequently used by residences and companies. Why? How can solar […]
Solar radiation is the basis for a surprising range of renewable energies. They are practically infinite. Added to this, solar energies are almost free of any emissions and with only few environment effects or hazards. The result of the solar technologies is a market that only tends to increase. Know more about the importance of […]
The push for energy independence, the possibility of saving money and the increase in environmental awareness in recent decades has certainly contributed to a steady increase in the spread of PV plants that create energy from renewable sources. Photovoltaic is certainly one of the protagonists, if not the main, given its extremely flexible nature to […]
