Do I need a generator?

For emergencies

If the grid goes down or your off-grid solar system needs a backup charging source, it's nice to have a "Plan B". A properly installed and maintained generator lets your family get through these unexpected occurrences with minimal inconvenience, keeping the power on while you wait it out.

For supplemental off-grid power

On occasion, factors like shading, limited roof space, extended overcast weather, etc. can impact the power you get from solar panels (learn more about maximizing solar panel efficiency). In those cases, a supplemental generator can fill the gap between what the panels produce and what your appliances demand, enabling you to continue living "off-grid" without utility power.

As a sole off-grid power source

Naturally, Wholesale Solar recommends our solar panels as the primary power source for your home, but we understand that's not always a possibility for every customer. We can also sell complete generator packages that are powerful enough to provide electricity to your entire house. An off-grid home can be powered directly by a generator or the generator can be used with an inverter and battery bank.
