Solar panels produce Direct Current (DC) voltage. They can be built to provide nearly any DC voltage. The voltage of the panel is impacted by cell size, cell construction, number of cells, panel size, and panel wiring. The result is panels from 0.5 volts to near 50 volts. Each volt range has a use.
For better protection, connect a 2.7V zener diode between SBAT pin and ground to maintain 2.7V if the solar cell voltage goes above 2.7V. A 1.5V, 100mA solar cell is sufficient to charge the battery and light the LED. It can be mono-crystalline or polycrystalline. The nominal current of the solar cell should not be more than 800mA.
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.
Resistor wattage = 2.1 x 0.3 = 0.63 watts or 1 watt. The solar panel can be rated at 18V, 3 amp. The battery specification is 12V, 7 Ah. The solar panel output voltage is regulated using the LM338 voltage regulator. Make sure that the 5K pot of the LM338 circuit is precisely adjusted to produce 14V for charging the 12V battery.
The 4V level ensures that the battery is never overcharged (at 4.2V) and this also allows the circuit charge the battery without a constant current supply. The following solar powered garden light was designed by Mr. Guido which includes additional features such over charge and low charge cut off for the battery and with a Schmidt trigger.

The solar panel supplies the peak voltage of 6 V, at 500 ma during daytime, which charges the battery as long as this voltage is available from the solar panel. The resistor Rx keeps the charging current to a safe lower level so that even after the battery is fully charged, the minimal current does not harm the battery.
Step 3: Calculate the capacity of the Solar Battery Bank. In the absence of backup power sources like the grid or a generator, the battery bank should have enough energy capacity (measured in Watt-hours) to sustain operation for several days during periods of low input from the solar array.
A higher voltage solar system, stepped down to match your battery bank, can increase efficiency and has the added benefit of reducing wire size and power loss, particularly over longer distances. Yet, it''s crucial to remember that a suitable charge controller is needed to safely regulate this voltage step-down and guard your battery bank ...

Therefore, giving a random figure to the voltage produced by the solar lights in your garden is not possible. But a general calculation states that the maximum voltage produced by a single solar cell is 0.45 volts.

Portable solar panels can be set up in a garden to power small electric devices. Solar-powered garden lights usually cost between £30 and £200. Large roof-mounted solar panels cost a lot of money, and not everyone has the finances or roof-space for them.
In a parallel connection, if one panel is shaded or not working, it won''t affect the performance of the other panels significantly. Understanding the effects of series and parallel connections is crucial when designing your solar panel system. Depending on your energy needs and the available sunlight, you can determine the optimal configuration that ensures maximum …

By using a single cell, it is only necessary for the solar panel to produce a voltage above 1.2v for charging to occur. This can be achieved with 3 cells, but if an additional cell is included, the voltage from the panel will rise above 1.2v when the day is not very sunny and thus the battery will be charged almost all the time during the day.
