For now try to navigate the vast landscape of manufacturers of photovoltaic modules is very useful to compare a card that gives an overview of the characteristics and significant numbers of the various modules on the market in this site:

  • Type :

    monocrystalline coefficient calculation = 1

    Polycrystalline (processing of waste from different mergers) calculation coefficient = 0.98

    micro-amorphous ratio calculation = 0.96

    amorphous coefficient calculation = 0.94

  • Tolerance:

    The difficulty in processing silicon module makes any different, even if they belong to the same merger. The manufacturer claims € / W for a value in W, then delivery (if honest) an average close to that value. If the tolerance is> 1.5%, obliges us to unpack all the modules and split strings in 3 groups, the highest performers, the middle and the poor, gaining the customer for 20 years 5% avoiding more losses smish smash: In the connection string in a series of poorly performing module throttle the performance of valid modules. coefficient calculation = (100-toll) / 100 (the smaller the tolerance the greater the convenience)

  • % Efficiency:

    watts per square meter in percentage when the sun shines 1000W per square meter, the most significant for Quality

  • Temperature Coefficient:

    watts less per degree centigrade more. coefficient calculation Watt = 75 ° C / W AT 25 ° C (STC standard test condition). This builds the true value of the coefficient of performance, not that of "showcase", as 1000W per square meter of sunlight with the temperature of a nearly black exceeds 65 ° C. In the calculation we used 75 ° to give due weight to this figure.

  • warranty against manufacturing defects :

    coefficient calculation = (year + 200) / 200. (A value of 200 is used to enforce the guarantee each year half a percentage point).

  • warranty on power output:

    not counted because equal for all, 80% after 25 years

TECHNICAL

The spurious calculation produces a number (without the sense of a unit of measure), but directly proportional to the quality technique. To understand this better make an example: Aleo 225 poly to 75 degrees = P AT 75°C / Pmax AT 25 °C (STC) efficiency% x (100-toll) / 100 x coeff. Type = (-0.48% of 225 is 1.08 W / °C x (75-25 °C) = 1.08 x50 = 54, which 225-54 = 171/225 x 13.7 x 0.97 x 0.98 = 9.90 a number that by itself means nothing, but compared with the other gives us the ranking of technical convenience.

ABSOLUTE

The calculation takes into account: technical quality coefficient x Warranty / euro/Watt . In the above example would be: 9.90 x (10 +200) / 200: 2.12 € / W = 4.9 (value of 200 is used to enforce each year warranty half a percentage point).
