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.
Can you mix different solar panels?
Mixing solar panels of various voltage or wattage, or produced by different manufacturers, is a frequently asked question by most DIYers. 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.
Are all solar panels the same?
Therefore it's not easy to find an exact panel match of different solar vendors. 'Exact match' means both almost similar ratings and ratings degradation. For panels connected in series, voltage is additive while current is the same, provided however that all the panels have equal current rating.
Before we talk about mixing solar panel sizes, lets have a refresher for some, or a crash course for others on how wiring solar panels in parallel vs series affects their voltage and amperage. Wiring solar panels in series adds their voltages while their amperages stay the same.
Can solar panels be used together?
From sailboat solar panel installation to residential panels to installing solar panels on a van, certain basic electrical rules apply. So yes, they can be used together. But to mix different wattage solar panels, it's crucial that you first understand the correct way to do it. A solar panel's wiring is connected either in series or parallel.
Are solar panels connected in series?
When you connect solar panels in series, the total output current of the solar array is the same as the current passing through a single panel, while the total output voltage is a sum of the voltage drops on each solar panel. The latter is only valid provided that the panels connected are of the same type and power rating.
Can I connect different solar panels in a solar array?
Connect only in series panels of the different brands and of the same current. Connect in parallel panels of different brands and of the same voltage. Connecting different solar panels in a solar array is not recommended since either the voltage or the current might get reduced.
