FAQ

Common Questions

Do I need an inverter if I only want to charge my battery?

No — an inverter isn't needed just to charge a battery. You'll only need one if you plan to run AC appliances like a TV or refrigerator directly off the battery.

Will this panel work in winter?

Yes — cooler temperatures can actually improve panel performance. Just keep it clear of snow buildup, shade, or other obstructions to maintain output.

Can the panel drain my battery at night?

No, as long as a solar charge controller is installed in the system — it prevents reverse current from flowing back into the battery after dark.

How long will the panel last?

It carries a 25-year performance warranty: at least 95% of rated output after 5 years, 90% after 10 years, and 80% after 25 years.

What color options are available?

The MEGA 100 is available in Silver or Onyx (Black) finish.
