High voltage solar panels have a nominal voltage output of 20V and require thinner copper wire to connect the array, the charge controller, and the battery bank. Ideal for grid-tied solar, a total of twelve panels in series will be below the grid-feed threshold of 600V.
High Voltage vs. Low Voltage Solar Panels: What’s The Difference? A standard off-the-shelf solar panel will have about 18 to 30 volts output, whereas a higher voltage output would be 60 or 72-volt panels. 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 just a homeowner who needs to power their home and connect it to the grid, then the standard voltage is usually best as it’s cheaper and easier. However, if you want an off-the-grid system or need higher power output per panel with a smaller number of panels, then a higher voltage solar panel will be better.
The performance of your solar energy system is also an essential consideration. 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.
However, if you want an off-the-grid system or need higher power output per panel with a smaller number of panels, then a higher voltage solar panel will be better. The size and output requirements determine what type you need…so just make sure to do your research before making a decision!
A low-voltage solar panel has much lower start-up costs than a high-voltage panel, which means that you can save money on the initial purchase. It’s always a great idea to strongly consider what your solar needs are going to be and then discuss these needs with your solar professional.
