Comparing Backup Power Options for Solar Systems

Complete & Continue Next Lesson Learn More

One of the most common questions we hear is:
"If the power goes out, will my solar still work?"
The short answer: not unless you have a backup system in place.

In this lesson, we’ll break down the most common backup power options for solar systems—including batteries, generators, and hybrid systems—so you can decide what’s best for your home, your lifestyle, and your peace of mind.

As always, we’re not here to upsell—we’re here to educate so you’re ready before the next outage hits.

IN THIS LESSON

Why Solar Alone Doesn’t Provide Backup During an Outage

Most grid-tied solar systems shut off automatically during a power outage to protect utility workers. This is a safety feature called anti-islanding.

You'll need some form of backup power if you want your lights, fridge, and devices to stay on during a blackout.

Option 1: Solar Battery Backup

How it works:

  • Your solar panels charge your battery during the day

  • The battery stores that power for later use

  • If the grid goes down, your home automatically switches to the battery

    • Clean, quiet, automatic

    • Powers essential circuits or full home (depending on system size)

    • No fuel, no fumes, no noise

    • Can be recharged by your panels daily

    • Higher upfront cost, depending on specific local incentives 

    • Limited power duration depending on usage and battery size

    • Homeowners wanting a seamless backup solution

    • People in areas with frequent outages or time-of-use billing

    • Those prioritizing sustainability and quiet operation

Option 2: Gas or Propane Generator

How it works:

  • A standby or portable generator kicks in when the grid goes down

  • It runs on gasoline, propane, or natural gas and powers part or all of the home

    • Lower initial cost than batteries

    • Can run for days with enough fuel

    • Good for long outages or high-energy needs

    • Noisy and requires regular maintenance

    • Creates emissions

    • Needs manual fueling (unless hardwired to gas line)

    • Doesn’t integrate with solar directly—panels shut off during outages unless paired with special equipment

    • Homes with infrequent but long outages

    • High energy users

    • Those who already have a generator in place

Option 3: Hybrid Solar + Generator System

How it works:

  • Combines solar panels, battery storage, and a generator

  • Battery provides instant power

  • Generator kicks in when battery depletes

    • Best of both worlds: clean power + long-duration backup

    • Can power entire home with proper system sizing

    • Generator preserves battery life during extended outages

    • Most expensive setup

    • Requires smart system integration

    • Needs thoughtful planning and installation

    • Off-grid homes

    • Families with critical energy needs (e.g., medical equipment)

    • Those looking for maximum reliability

Which Backup Option Is Right for You?

Ask yourself:

  • Do you live in an area with frequent blackouts?

  • How long do outages usually last?

  • Do you need whole-home or partial backup?

  • Is quiet, clean energy important to you?

  • Do you already have a generator—or want one?

At SolarShip, we walk you through every option based on your usage, goals, and home layout—so you’re not guessing or overpaying.

Key Takeaway:

Solar is amazing—but without backup, it's not a blackout solution. Whether you choose a battery, a generator, or both, the right system gives you power, protection, and peace of mind when it matters most.
