With a 12 or 24-panel solar array (4 to 8 kWp), 3-stage water purification system, lithium battery storage, multiple output ports, and an optional cellular router/modem, it's amazing we fit it all into a 6ft (2m) shipping container.
Key specifications to consider when evaluating solar panels are the wattage or power rating, efficiency percentage, operating voltage, current output, and the temperature coefficient that indicates how the panel's performance is affected by temperature changes.
