The rule of thumb is to size your inverter 1.25 bigger than your solar array. In some cases, you may need to use multiple inverters to meet your power needs or increase your system’s voltage. This practice, known as inverter stacking, involves connecting multiple inverters in parallel or series. [pdf]

A general rule of thumb is that you’ll need one watt of solar power for every hour that you want to run your lights. So, if you want to run your lights for 8 hours per day, you’ll need an 8-watt solar panel. [pdf]
[FAQS about How many watts of solar energy is bright enough]
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. 1. Open Circuit Voltage (Voc) 2. Voltage at Maximum Power (Vmp) .
To calculate the power (watts) provided by a solar panel we need to know the size of the electrical wave (volts) and the force of the current(amps) behind the wave. Most solar panels list two. .
Watts is a measure of work. It is the amount of energy the panel can provide to your system at maximum solar exposure at 25º C. It is calculated by multiplying Volts at Maximum Power (Vmp) and the Current at Maximum Power (Ipm). This calculation. Most 72 cell panels are wired in series to produce 24 volts, but could also have pairs of strings wired in parallel to produce more current at 12 volts. When looking at a panel of a given nominal voltage, a good rule of thumb for estimating the Vmp is to add about 20% to the nominal voltage. [pdf]
