What to Look for in a Solar Generator
When choosing a solar generator, consider these key factors:
- Battery Capacity: Measured in kilowatt-hours (kWh), this determines how much power the generator can store. Higher capacity is better for longer outages.
- Inverter Size: This affects how many devices the generator can power simultaneously and how large of an appliance it can support.
- Portability: Look at the size and weight. For home use, you may prioritize higher capacity over portability, but a balance is ideal.
- Recharging Time: Solar generators charge via solar panels, wall outlets, or car outlets. Choose a generator with fast charging time.
- Expandability: Some generators offer expandable battery options, giving you more flexibility based on your energy needs.
How Do Solar Generators Work?
Solar generators convert energy from solar panels into electricity and store it in a battery for later use. Here’s a basic breakdown:
- Solar Panels capture sunlight and convert it into DC electricity.
- This electricity is sent to the charge controller, which regulates the flow of power and prevents overcharging.
- The battery stores the DC electricity. The larger the battery capacity, the more energy you can store.
- An inverter converts the DC power into AC power, which most household appliances require.
- Finally, you can plug devices directly into the generator’s AC outlets or USB ports to power them during outages or emergencies.

How We Test Solar Generators
We assess solar generators by subjecting them to real-world scenarios to evaluate their performance. First, we measure battery capacity and assess how long each model can sustain critical appliances like refrigerators, lights, and medical devices during a simulated power outage. We test the recharging time, both using solar panels and other methods like wall or car charging, to evaluate how quickly the generator can return to full capacity.
We also check the portability and design to ensure that the unit can be easily moved around your home or even taken on the go if necessary. Durability is tested by placing the units in different weather conditions. Finally, we use different power-drawing devices like laptops, fans, and tools to measure efficiency across the range of power needs.
How to Choose the Best Solar Generator for Your Home
Choosing the best solar generator for your home backup involves understanding your energy needs. Start by estimating your power requirements. Add up the wattage of your essential devices—refrigerators, lights, medical devices, etc.—to determine the minimum battery capacity you’ll need. Aim for at least 2kWh of battery capacity for a small home, and up to 5kWh or more for larger homes with multiple devices.
Look for expandable battery options if you want the flexibility to increase capacity over time. Also, check for charging options—some models offer faster solar panel charging, which is crucial during extended power outages. Finally, consider portability and storage space—larger units may provide more power but are heavier and harder to move.
