What we mean by energy efficiency Much has been said and talk about energy efficiency, but do we really know what is energy efficiency? Efficiency is the maximization of resources for obtaining a result. We are more efficient when we use fewer resources for the same purpose or when the same resources we get a […]
New record efficiency for photovoltaic
The industry is already able to transform more than 40% of the energy of sunlight directly into useful electricity Recently announced a new record efficiency, in this case the call module efficiency. Usually is separated into cell efficiency, this being achieved only by the cell efficiency, and module efficiency, that which is achieved with the […]
Spain returns to bet on renewable energy
Last week pleasantly surprised us a new document made public prepared by the Ministry of Industry on the planning of the electricity sector for the period 2015-2020, in which, either by the proximity of an election or by the goals set in Europe objectives for 2020, Spain opened the door again to install new renewable […]

The government wants us to pay for the sun
After the biggest cut in the support to the renewable energies sector made by any government in the world, last July 12th, with the approval of the Royal Decree-Law 9/2013, which adopts urgent measures to guarantee the financial stability of the electrical system, the government of this banana monarchy in which we live has proposed […]
What is a solar inverter?
The solar inverter is responsible for transforming the direct current from the solar panels into alternating current for household use. These devices can be connected directly to the grid of housing. When a solar panel is connected to the solar inverter, home power meter will reduce the speed or rotate counterclockwise. Solar inverters use several solar […]

Good news for photovoltaic solar energy!
More solar panels can be purchased! And the “back-up toll” will be stopped further Today the BOE published the Order FOM/1635/2013 updating the Basic Document DB-HE “Energy Saving”, of the Technical Building Code, which establishes a minimum photovoltaic contribution of electrical energy in new buildings. This revision of the DB-HE will lead to the banishment […]
