If you''re combining two or more panels, the voltage or amperage is going to increase, which should also be taken into account.
Get a quoteTypically, a single solar cell produces around 0.5 to 0.6 volts. When multiple cells are connected in series within a solar panel, their voltages add up. For example, a 60-cell solar panel commonly used in residential settings can produce around 30 to 36 volts under standard test conditions.

Get a quoteA solar panel will need to provide a minimum of 5 watts when charging. Ideally 10 to 15 watts of charging power is recommended. A lower wattage means that you will need more time to charge your phone. In order to fully charge the phone battery, the solar panel charger voltage must at least match the voltage of a fully charged phone battery.
Solar panels produce DC voltage that ranges from 12 volts to 24 volts (typical). Solar panels convert sunlight to electricity, with voltages depending on the number of cells in the panel. Batteries store the energy produced in the form of direct current (DC), and their voltage should match the solar panel’s voltage.
With solar panels, we can charge batteries, and batteries usually have 12V, 24V, or 48V input and output voltage. It is the job of the charge controller to produce a 12V DC current that charges the battery. Open circuit 20.88V voltage is the voltage that comes directly from the 36-cell solar panel.
Most common solar panels include 32 cells, 36 cells, 48 cells, 60 cells, 72 cells, or 96 cells. Each PV cell produces anywhere between 0.5V and 0.6V, according to Wikipedia; this is known as Open-Circuit Voltage or V OC for short. To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C).
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.
Maximum Power Voltage: The voltage at which your panel produces the most power typically falls between 18V to 36V. So, when you’re thinking about solar panel voltage, just remember that it’s the driving force that contributes to your energy production.
