Understanding wattage is essential for determining how much energy a solar panel can produce and, consequently, how much power your devices or appliances can draw from it. For example, a solar panel with a voltage of 20V and an …
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.
Much like voltage, there are two important values for current. The first is the short circuit current (Isc). Isc is the maximum amount of current a module can supply and it occurs when the module is shorted and there is no voltage produced by the solar. The second important current is the power point current (Ipp).
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:
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.
This means that when this solar panel is producing 100 Watts of power under Standard Test Conditions, It will be generating 5.62 Amps of current. On the other hand, the Short Circuit Current rating (Isc) on a solar panel, as the name suggests, indicates the amount of current produced by the solar panel when it’s short-circuited.
Control Circuit: The control circuit (Figure 3) is used to control the current drawn from the solar panel, and to condition the current and voltage signals produced during the measurements. The circuit draws about 8 milliamps and can be powered by a 9-volt battery or by any DC voltage typically in the 9 to 12 volt range.
