The higher voltage of course means more power in one go, which could mean you can run a larger load at the same time. If you are going to be building your own system or have some advanced knowledge of solar panels, then you will want to look for higher voltage as it allows more power output per panel and means fewer panels needed in total.
To these customers, a standard voltage is just fine as long as the wattage meets their needs. The size of your solar panel will also determine the voltage output. The larger the solar panel, the higher its voltage-this means a large system can have high voltage panels with many watts of power!
The voltage on solar panels just rises up to the VOC which is basically an open on the connector and it doesn't heat up or produce any power. The job of the Charge Controller is to find a voltage where the panel produces a maximum amount of power.
When deciding between high voltage and low voltage solar panels, keep in mind that higher voltage systems are more efficient in general for your off-grid solar power system. A 48V system is the most efficient and cost-effective per watt-hour generated as compared to 24V and 12V systems.
High-voltage panels have the potential to improve efficiency, particularly in bigger installations or across long distances. Low-voltage systems may be less efficient, but they may be enough for smaller installations or systems requiring less power. If interested, you can also explore 16 Ways to Increase Solar Panel Efficiency. 3.
Consider a scenario where you have a 200W solar panel with a working voltage of 20V and an amperage of 10A. To charge a 12V battery system, you’re going to need a charge controller to step down the voltage and regulate the current to prevent overcharging.

Online Services Email ContactIf your panels are making 100 amps and your Charge Controller ISC limit is 15 Amps then I do not recommend doing it. The way around it is to put your panels in series which boosts the voltage and also keeps the current low. Wattage is a simple Volts times Current. So if you have 350 volts and 15 amps for the panels then you have 5250 watts.
