How Much Does a Solar Generator Cost? | Real 2026 Price Bands

A solar generator costs $200 to $900 for small portable units, $1,000 to $3,000 for mid-size home backup, and $5,000 to $15,000+ for whole-home systems.

If you’re shopping for backup power, the wide price range for a solar generator comes down to three things: battery capacity, inverter wattage, and whether solar panels are included. A 300Wh unit for camping costs a few hundred dollars, while a system that can run your refrigerator during an outage runs into the thousands. Here’s what each price tier actually buys.

Why Solar Generator Prices Vary So Much

The single biggest driver of cost is battery capacity, measured in watt-hours (Wh). Small units with 300–800Wh batteries handle phones, laptops, and small appliances and typically cost $400–$900. Mid-range systems with 1–3kWh of storage and 1,000–2,000W inverters run $900–$2,500. Whole-home setups with 3–15kWh or more and 3,000W+ inverters cost $2,500–$10,000+.

Whether panels are bundled matters just as much. The same power station can appear at two very different prices depending on whether it ships alone or as a kit with solar panels. EcoFlow’s US store, for example, lists solar generators at $669, $1,499, and $2,899 on its collection page — a spread that reflects both capacity and bundle contents.

For budget buyers, our tested roundup of the best budget solar generator options breaks down which affordable models actually deliver reliable power.

Solar Generator Cost by Size and Use

These bundles pair a power station with the panels needed to recharge it.

What Does a Solar Generator Cost Per kWh Over Time?

Looking at lifetime cost per kilowatt-hour gives a fairer comparison than sticker price. The EcoFlow Delta 2 with 400W of panels came in lowest at about $0.30/kWh — competitive with grid power in many regions and well below gas generator fuel costs.

These figures use “levelized cost of electricity” (LCOE), which spreads the upfront purchase across the total energy the system will produce over its lifespan. The math favors systems with larger battery capacity and more panel wattage, since the panels keep working for decades while the battery is the component that eventually wears out.

Home Backup and Whole-Home Solar Generator Costs

For serious home backup, the price climbs fast. The 30% federal solar tax credit can cut those figures meaningfully.

More modest home-backup configurations are far cheaper. Unit-only solar generators typically run $500–$5,000, while systems with panels rise to about $1,200–$6,000. High-capacity off-grid builds can exceed $8,000. The wide spread comes down to whether you need to power a refrigerator for a few hours or run an entire household indefinitely.

One caution: don’t confuse portable solar generator pricing with whole-home solar panel installation.

Jackery’s solar generator cost comparison provides the detailed breakdown behind these home-backup figures.

Before you buy, decide what you actually need to power. A $400 portable unit keeps your phone and laptop alive during a short outage. A $2,000 mid-size system runs your refrigerator, lights, and a sump pump for days. A $20,000 whole-home setup replaces grid dependence almost entirely. Matching the system to the job is the difference between overspending and being stranded.
