FEATURES: In 2006 it is obligatory to install solar energy
Photovoltaic Solar Energy to sell electricity
anyone currently
or entity can install solar energy to sell electricity to utilities, which have the obligation to buy. Furthermore current legislation sets a higher price than 575% of the average electricity tariff.
photovoltaic solar energy requires installation connected to the mains. These systems are very reliable and manufacturers usually guarantee 90% of power during the first 10 years of life of the collectors, while subsequently provides 80% power to 25 years. In addition, the average life expectancy of photovoltaic modules exceed 40 years.
Comparison of technologies to produce electricity:
Photovoltaic Static
consists of panels with a static orientation and inclination. The return depends on an optimal orientation of the modules and solar radiation receiving the locality in which it is installed. Its main advantage is that they are cheaper and can be fully integrated in roofs of buildings or houses. These facilities can be made in all types of roofs, covered both industrial and country houses in urban buildings.
tracked Photovoltaic Solar
1 - Follow-up spot of the panels with the sun all day long (from east to west during the day). Increased performance by 29% compared to static system.
2 - Monitoring the seasonal tilt year-round (spherical zenith) (Solsiticio from winter to summer and vice versa). Increase performance by 39% if you combine the two types of monitoring. Called dual-axis solar tracker or two axes. In addition, there are supports motorized or electrical systems operated by gravity.
With these systems, ensures that the photovoltaic panels have a high energy collection throughout the day as well as change the position of the sun at the stations. In conclusion, increased profitability is up to 10% higher than a static, given that the payoff is much greater than the increased cost. In addition trackers take up less space than a photovoltaic system for the same installed capacity.
