The voltage of a solar panel is the result of individual solar cell voltage, the number of those cells, and how the cells are connected within the panel. Every cell and panel has two voltage ratings. The Voc is the amount of voltage the device can produce with no load at 25º C.
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).
If you know the number of PV cells in a solar panel, you can, by using 0.58V per PV cell voltage, calculate the total solar panel output voltage for a 36-cell panel, for example. You only need to sum up all the voltages of the individual photovoltaic cells (since they are wired in series, instead of wires in parallel). Here is this calculation:
36-Cell Solar Panel Output Voltage = 36 × 0.58V = 20.88V What is especially confusing, however, is that this 36-cell solar panel will usually have a nominal voltage rating of 12V. Despite the output voltage being 18.56 volts, we still consider this a 12-volt solar panel.
To be more accurate, a typical open circuit voltage of a solar cell is 0.58 volts (at 77°F or 25°C). All the PV cells in all solar panels have the same 0.58V voltage. Because we connect them in series, the total output voltage is the sum of the voltages of individual PV cells. Within the solar panel, the PV cells are wired in series.
A typical 60-cell solar panel can generate a DC voltage between 20 and 40 volts. Just like that – you’ve calculated your solar panel voltage! Follow these steps, and you’ll be a solar measuring and calculating pro in no time. To get the most out of your solar panels, you need to orient them correctly.

Keep in mind that the volt meter has a practically non-existent load on the cell, so after the cell rests for a few moments, it''s open circuit voltage can rebound to around 3.0V, but as soon as you put a real load on it, it can drop to a fraction of a volt.

Planning for more than 10 years is silly. To me it''s not reasonable to pay for 40% extra capacity and not use it, but 20% extra is much more reasonable. 3.4V is a resting open circuit voltage of a fully charged cell, but it is too low for a charge voltage. In my experience 3.5V is the minimum charge voltage, even for very long cell life.
