What a solar generator actually is
The term is marketing rather than a product category. A "solar generator" is a portable power station plus one or more solar panels, usually sold as a bundle.
Nothing about the battery is special. The same unit sold without a panel is the same unit. What the bundle buys you is a matched connector and a single purchase decision, and sometimes a discount.
That matters at this budget, because it means you can and often should buy the two halves separately and choose each on its merits.
How to split a thousand dollars
The common mistake is buying the largest battery the budget allows and adding a token 60W or 100W panel. That produces a large store of energy you cannot refill.
| Split | Behaves like | Good for |
|---|
| All battery, one small panel | A big store with a trickle refill | A single long outage, then nothing |
|---|
| Mid battery, 200W of panel | A daily budget you can actually live on | Multi-day outages, camping, off-grid weekends |
|---|
| Small battery, 300W of panel | A generation-led system | Sunny climates and daytime loads |
|---|
The middle row is right for most people. Roughly half the budget on a 400-550Wh LiFePO4 battery and half on 200W of panel produces a system that genuinely refills day to day.
The number that governs everything
A 100W panel does not produce 100 watt-hours per hour of daylight. Across a good summer day it returns something like 400 to 500 watt-hours, once you account for sun angle, temperature, cloud and controller losses.
| Array | Good summer day | Overcast or winter |
|---|
| 100 W | 400-500 Wh | Often under 150 Wh |
|---|
| 200 W | 800-1,000 Wh | Often under 300 Wh |
|---|
| 300 W | 1,200-1,500 Wh | Often under 450 Wh |
|---|
Figures use the 400-500Wh per 100W per good summer day convention used across this site. Winter and overcast figures vary enormously with latitude and weather — the cloudy day page covers how far output falls.
Read the middle row against the battery you are considering. 200W of panel refills a 572Wh pack roughly twice over on a good day and not at all on a bad one, which is the honest shape of solar at this budget.
Check the input limit before buying panels
Every power station publishes a maximum solar input in watts and a voltage range, and exceeding either does nothing useful — the controller simply clips.
The units in this band typically accept 110W to 220W. Buying 400W of panel for a 110W input wastes most of it, and that is a genuinely common and expensive mistake.
Check the maximum input watts, the maximum voltage, and whether panels should be wired in series or parallel to stay inside both. The connector guide covers the wiring side.
Folding or rigid?
This is the decision that most affects value at this budget.
Folding panels cost considerably more per watt and are the right choice if the panel travels — camping, a balcony you bring it in from, a battery you carry.
Rigid panels are the cheapest honest watts available. If the panel has a permanent home on a shed, a fence or a flat roof, you get substantially more generation for the same money.
A lot of the best value at this budget is a mid-size battery plus two rigid panels semi-permanently mounted, rather than a bundle. The portable panel page covers the folding side properly.
What this budget will not do
Being clear saves disappointment.
- It will not run a refrigerator through a long outage. That needs the 1,000Wh band and more panel — the home backup page covers those combinations.
- It will not run anything that makes heat. A kettle, a heater, a hair dryer — all of them exceed the inverter, and none of them are within a day's generation anyway.
- It will not reach a hardwired circuit. No 240V, no transfer switch, no furnace or well pump.
- It will not produce much in winter. Output in December at northern latitudes can be a quarter of the July figure.
What it will do, reliably: keep phones, laptops, lighting, a router and a CPAP running indefinitely as long as the sun comes out every few days. For a lot of households that is the whole requirement.
The short version
- Split the budget roughly evenly. The panel is the half that gets skimped.
- 200W of panel is the threshold where a small battery becomes a daily budget.
- Check the input limit first. Panels beyond it are wasted money.
- Rigid panels if they have a home, folding if they travel.
