Learn how to install solar panels yourself with this video of how to wire solar panels together in parallel using a combiner box and breakers. https://www.altestore.com/store/Enclosures-Electrical-Safety/Electrical-Enclosures/Combiner-Pass-Through-Boxes/Midnite-Solar-MNPV3-Combiner-Box/p4567/ By combining the positive wires together and the negative wires together, you keep the voltage the same, but increase the current (amps). You would wire in parallel when the solar panels’ voltage matches the battery bank voltage, and you are using a PWM solar charge controller, which requires the solar array and battery bank voltages to match.
