Mixing Solar Panels Mppt

The principle of mppt is squeezing the maximum possible solar generated power from a solar panel by making it operate at the most efficient combination of voltage and current also known as maximum power point.

Mixing solar panels mppt.

One is 2x325w 72 cell panels in series feeding a victron 100 50 mppt. Mixing solar panels of various voltage or wattage or produced by different manufacturers is a frequently asked question by most diyers. The other array is a single 250w 60 cell panel feeding a separate victron 100 30 mppt. When connecting modules of dissimilar electrical characteristics in series it is each module s current that plays a heavy role in how the string is going to perform in the solar power system.

When mixing solar modules is important to remember that it is not the wattage of the modules that is important to consider. Though mixing different solar panels is not recommended it s not forbidden and things would be ok as long as each panel s electrical parameters voltage wattage amps are carefully considered. The result of the multiplication must not be higher than the maximum pv open circuit voltage as listed on the mppt datasheet. First look at the datasheets of the solar panels to see what their maximum open circuit voltage is.

Not planning on touching that one. Then multiply that by the number of panels that are in series in the array. Mixing solar panels in parallel total connected power 150w 150w 150w 150w 600w unlike connection in series if among modules connected in parallel there is a module of power output lower than the output of the other modules this might not affect seriously the total power output of the array provided that this module has equal to the other modules rated voltage. This allows you to add additional panels to an existing battery based system and still maximize the output of both sub arrays.
