So you’ve gone solar—congrats! You’re generating clean, renewable energy, slashing your utility bills, and reducing your carbon footprint. But here’s the truth: solar power isn’t invincible. When the grid goes down or the sun hides behind the clouds for days, what keeps the lights on?
That’s where backup generators come in. In this article, we’ll explore why even solar-powered homes benefit from having a reliable backup generator in place.
Solar panels capture sunlight and convert it into electricity. This electricity can be used immediately or stored in batteries. The process involves:
Photovoltaic (PV) panels that capture sunlight
Inverters that convert DC to usable AC power
Battery banks for energy storage (if installed)
Inverters regulate the electricity flow, while batteries store excess energy for later use—like at night or during cloudy days. However, both systems have limits.
Solar panels depend on the sun. On overcast days or during storms, power generation drops significantly.
Batteries are expensive and have limited capacity. Once they’re drained, you’re out of luck unless the sun comes back—or you’ve got a generator.
Unless you’ve invested in a robust battery system, your solar setup can’t generate power at night. If your batteries are empty, you’re back to relying on the grid—or a generator.
Most residential systems are grid-tied, meaning they shut down when the utility grid is down—for safety. Yes, even if the sun is shining!
Net metering lets you sell extra power back to the grid. But if the grid fails, so does this system. You can’t draw from net metering credits during a blackout.
A generator ensures that your lights, fridge, and critical appliances stay running—even when the solar panels aren’t producing.
Medical equipment, security systems, internet routers—many homes rely on always-on devices. A generator fills in the gaps when solar can't.
Think hurricanes, wildfires, or ice storms. In these high-stress moments, reliable backup power can be a lifeline.
Ideal for temporary use or emergencies, these are affordable and versatile. Just roll them out, fire them up, and you’ve got power.
Permanently installed and often paired with an automatic switch. These kick in automatically during an outage and can power your whole house.
For eco-conscious users, solar generators with battery backups are a silent, green option—but they still may not match diesel's power output.
An ATS detects when the grid goes down and automatically switches to generator power. Seamless and fast.
You flip the switch manually. More budget-friendly but requires someone to be home during outages.
These systems combine solar, battery, and generator capabilities. They offer maximum uptime and energy efficiency.
Size your generator based on:
Total wattage of essential devices
Duration of expected outages
Future expansion
Diesel: Long shelf life, reliable, high power
Gasoline: Easy to find but degrades faster
Propane/Natural Gas: Clean burning, less maintenance
Some generators are whisper-quiet, others roar like a lawnmower. Consider noise ordinances, neighbors, and your own sanity.
Run your generator monthly (even if you don’t need it)
Change oil and filters regularly
Check fuel quality and battery charge
Clean air intakes and exhausts
Inspect connections between solar inverter and generator
Having a solar home is awesome—it’s sustainable, efficient, and forward-thinking. But relying on sunlight alone can leave you in the dark when you need power most.
That’s why a backup generator is not just an accessory; it’s a necessity.
Whether it’s powering your essentials at night, supporting you during grid failures, or keeping your home secure during storms, a generator complements your solar system like peanut butter complements jelly.
Don’t wait for the next blackout to make the switch—empower your solar home with backup today.
