Pv Solar Panels
Buying solar panels?
Photovoltaic panels are viable?
Photovoltaic modules or solar panels are definitely sustainable energy solution for homes that provides the operating costs. Program with the SEI / CER generation Micro is now ready for installation of implementation of solar panels will also fight hard in the resort on the right.
Cells PV have been around for centuries, but even now, the search is on newer technologies. This is because the efficiency of energy solar PV modules to convert commercially available is never more than 13 -15% in the field. Beauty is good and each watt generated is free and renewable. About 80% of all PV modules manufactured for terrestrial applications are still the type of generation first crystal.
Solar panels are all equal?
Certainly not! The same so there are many different materials, there are details that differ from the different performances. Quality standards is another matter. Unless you are at least familiar with basic electricity and the distribution of it in houses that you'd better leave everything to a professional. But for those who are technically spirit of these facts to assess when buying solar panels.
- Standards quality
Like all other equipment imported into the EU PV market solar panels should also be consistent with EC ISI BS EN or relating to the item. ISO 9000 quality management series and the ISO 14000, environmental management system etc are other standards relevant to the manufacturing process and installation. You will have to ensure manufacturer's certificate standards for model and year of manufacture of the unit you intend to buy. (These validities must be periodically renewed).
- The performance data – what to look for
Specification: Solar Cell-type, size and profile
Number of cells and how they are connected (series / Parallel)
Typical application Voltage DC
Maximum voltage V DC
Module Size length x width x height (mm)
Module Weight (kg)
Front glass thickness (mm) and if wet.
Temperature range (0 ° C)
Nominal Operating Cell Temperature and tolerance – (0 C)
Safe nominal diameter hail measured at 80 kmph (mm)
Continuous wind pressure safe (kmph)
Size connection cable type / special connector needed or not
Electrical specifications: rated power (in watts)
Tolerance (%)
-Rated current (A)
Rated voltage (V)
Short-circuit Current (A)
Open circuit voltage (V)
Temperature Coefficient Voltage (V / 0 C)
Coefficient, the current temperature (% / 0 C)
Temperature coefficient of power (% / 0 C)
Characteristic voltage VS-Amp
(@ Irradiance 1000W / m 2)
Characteristic curve vs Amps Watts
(@ Irradiance 1000W / m 2)
Conversion efficiency (%)
Characteristic Construction: Type of support frame
Frame material
Method of mounting brackets and the material
The method of sealing water
Warranty: Applicable warranty on critical components such as solar cells and module (Complete), frame and fasteners (if provided by the supplier of the module), cables and connectors, Method of sealing water, etc.
In a performance evaluation over details and features allow you to make an apple to apple comparison of the multitude of types and brands of modules Solar currently on the market. As said earlier if this is too techie, it is prudent to enlist the help of a panel Solar specialist (if all other avenue fails) are still available with suppliers and manufacturing agents. This evaluation should naturally precede any assessment of the price to protect your valuable investment.
