FAQ
Is there a difference between solar thermal and photovoltaic?
Yes. In fact the only thing they have in common is that both use the sun.*
But just as in the applications we use a thermal collectors that heat water and have a very simple technology, photovoltaic applications they do is produce electricity from modules built silicon semiconductor complex and advanced technology.
How does one actually installing solar photovoltaics connected to the network?
Photovoltaic modules produce electricity when they receive the sun’s radiation. This electricity is current, has a stable polarity, like a battery.
The current generated by the modules is converted into alternating current frequency and voltage of the same stage as the public distribution network through a set of converters.
Once converted, solar electricity is counted and injected into the network, being available to be consumed in the same place of production or any other consumer nearby.
Why in a country with so much sun there are so few facilities?
Mainly by low-cost so far have protected forms of energy by the government. While the canister of butane, diesel or heating electricity prices have state control of inflation has been difficult to compete with teams that require a high initial investment in exchange for years of clean production.
Similarly, countries with expensive conventional energy such as Greece, Turkey and even China has become customary production equipment for solar hot water on the roofs of buildings.
Another reason has been hesitant and erratic actions of the administration. Until we began to implement the ordinance and now the solar Technical Building Code makes it mandatory that these facilities in all new buildings had not begun to grow the fleet of solar thermal.
Is it profitable to invest in solar energy?
Finally, our government has laid the foundation, by paying a premium for the production of solar power, which provides a return of between 7 and 10% for those who invest in solar energy to help the country meet the Kyoto Protocol, the EU’s objectives and ultimately improving our sustainability.
If we add to that the return we get a guarantee from the kind of treasury bills for Sustainability.
Can you define “biomass”?
Biomass is the name we give to all fuels from organic matter. From the wood to gas that emerges from a garbage dump via biofuels which are now more fashionable as biodiesel or ethanol to replace gasoline or diesel.
Does the use of renewable energy will prevent global climate change?
Given that climate change has already begun and therefore we can not avoid the use of solar energy, wind energy, biomass, hydro, geothermal and energy from the sea (waves, tides and currents) is the only option we have to try to minimize its effects.
You can always find a combination of renewable energy that would serve any area, if it does not mean that the ecological footprint of this area is excessive and should reduce their consumption level to be sustainable.
