The photovoltaic panels are vital?

photovoltaic modules or solar panels are undoubtedly the sustainable energy solution for homes that offer lower operating costs. With the '/ SEI program of micro-generation CER is now ready to be difficult to implement the installation of photovoltaic panels on the right plays in the area.

Photovoltaic cells have been there for centuries, but now the search is for the latest technologies. Since the conversion efficiency of solar energy tradeThe photovoltaic modules are available not more than 13 -15% in actual use. The nice thing is though, every watt generated in this way is free and can be extended. About 80% of photovoltaic modules for terrestrial applications have already done the first generation of crystalline.

If all the solar panels the same?

Of course not! Similarly there are many different materials are used, there are several performance disparate elements. Quality standards is anotherMatter at all. Unless you have at least basic knowledge of electricity and distribution of property you would do better to leave everything to a professional. But for those more experienced are some facts to consider if you buy solar panels.

Quality Standards

Like all other devices imported to the EU market for solar PV modules should also aim to meet the EC, ISI, BS EN or in connection with '.Quality Management ISO 9000 and ISO 14000 environmental management system, and so are the other rules relating to its manufacturing process and the complex. It is necessary to ensure standard certificates meet the manufacturer's model and year of manufacture of the device you intend to buy. (The validity should be replaced regularly).

In an evaluation of the services listed above andspecial features that allow you to make an apple to apples comparison of the variety of styles and brands of solar modules available today. As expected, when it comes to a technician, we recommend the assistance of a specialist, the solar panel (when all other failed Avenue) are still available with suppliers and manufacturers have agents. This assessment technique must obviously precede any assessment of the costs for your important investment to protect.
