10 Best Solar Generators 2025 in the United States

The EF ECOFLOW Solar Generator DELTA2 is a robust solution for those seeking clean and portable power, perfect for camping, RVs, or as a backup at home. One of its standout features is the impressive 1800W output, which allows it to power most household appliances without any emissions or noise, making it a great alternative to traditional generators. Its LFP battery offers a significant lifespan of over 3000 charge cycles, which means this unit will last for years with proper care. The ability to expand its capacity from 1kWh to 3kWh by adding extra batteries is a great plus for users with greater power needs.

Portability is another strong point, as the DELTA2 and its 220W bifacial solar panel are designed to be mobile, making them suitable for outdoor activities. The solar panel's ability to capture up to 25% more energy thanks to its bifacial design enhances its efficiency significantly.

The EF ECOFLOW Solar Generator DELTA2 is an excellent choice for individuals or families who need reliable, eco-friendly power for outdoor adventures or backup during outages.

The Jackery Explorer 1000 v2 is a portable solar generator featuring a solid 1,070Wh lithium iron phosphate (LiFePO4) battery, providing a reliable power source that lasts over 10 years with more than 4,000 charge cycles. It delivers up to 1,500W of continuous power with a surge capacity of 3,000W, sufficient to run appliances like fridges, AC units, or electric pots. The unit is relatively lightweight at 23.8 pounds and includes a foldable handle, making it reasonably easy to carry for camping or emergency use.

It supports multiple output options, including three AC outlets, two USB-C ports (one with fast 100W charging), one USB-A, and a car DC port, allowing you to charge several devices simultaneously. A standout feature is its fast recharge capability, able to fully charge in as little as one hour using AC power with an emergency mode activated via the Jackery app, though it typically defaults to a safer 1.7-hour charge time. The generator is compatible only with Jackery-brand solar panels, which limits solar input options if you already have other panels. It also offers useful smart app controls to optimize charging modes and noise levels, but the solar panel is sold separately, adding to the total investment.

Thanks to its durable and safe LFP battery, the device provides good longevity, though it might feel a bit heavy compared to smaller models if ultra-portability is a priority. This power station is well-suited for users seeking a powerful, durable, and quick-charging solar generator primarily for camping, RV use, or backup emergency power, while keeping in mind the need to purchase compatible solar panels separately.

The Jackery HomePower 3000 is a powerful solar generator designed to provide reliable backup power for your home and outdoor activities. It features a large 3,072Wh lithium iron phosphate (LiFePO4) battery, known for long life and safety, which can handle up to 3,600 watts of continuous power and surges up to 7,200 watts. This means it can keep essential appliances like refrigerators, fans, and lights running smoothly during power outages for hours or even days. The built-in UPS switches power within 20 milliseconds, ensuring important devices like security systems or medical equipment don't lose power unexpectedly.

The generator supports charging through various methods including AC outlets, car chargers, gas generators, and solar panels (two included 200W panels), providing flexibility whether you're at home or traveling. It can recharge quickly—fully in about 1.7 hours with hybrid AC/DC charging, or up to 80% in 9 hours with solar panels. While it is the lightest and smallest in its class, weighing about 60 pounds, it’s still somewhat bulky for casual carrying but manageable for those prioritizing home backup or RV use. Jackery’s AI-driven ChargeShield 2.0 technology helps speed up charging and extends battery life, promising around 4,000 cycles. The device's build quality is solid with a honeycomb bottom shell for added strength.

Despite its portability improvements, it remains heavier than smaller power stations, and the solar charging time may be longer than some users want for emergency use. Also, the initial cost might be higher than simpler models, but the tax credit could help offset this. This solar generator is well-suited for homeowners looking for dependable, high-capacity backup power and RV users needing versatile, clean energy on the go.
