With a projected lifespan generally between 25 to 30 years, the longevity of these cells provides a stable source of energy generation. This lifespan can be affected by several key factors, including environmental conditions, installation quality, and ongoing maintenance practices.

Unlike batteries, solar cells don't have a fixed wattage—it depends on two factors: Voltage (V): In this case, 21 volts. Current (Amps): Measured under standard test conditions (STC). Here's the golden formula: Watts = Volts × Amps. For example, a 21V solar cell producing 5 amps.
