Mixing Different Size Solar Panels

In order to get the results you are looking for though you must take all the fa.

Mixing different size solar panels.

Typically the mixing of solar modules from different manufacturers and of dissimilar voltages wattages and amperages is not recommended. However if you take certain factors into careful consideration you can easily achieve this goal. So they usually put a diode between the panel and the battery. A common question asked by many itechworld customers.

Also read why solar power panels are necessary for you. When you intend to wire two panels produced by different vendors the vendors are not the problem. This diode does lose about 5 percent of the power 5 volt drop so more with a 6 volt system less in a 24 volt 5 6 about 15 percent 5 24 about 2 percent. Can i mix different size solar panels.

Can i join one of your 120w solar panels with my existing 200w solar panel on my roof to get 320w mixing and matching solar panels can be done. Completely discharging it over time. But at night the solar panel looks like a resistor and will slightly discharge the battery. 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.

Your solar controller must be big enough to handle the combined amps. If you connect same voltage panels together in parallel you just add the amperage together to get the total amps available.
