However, if you want a smaller, less expensive option, consider the Jackery Explorer 500W. It’s always good to have a backup in life, especially when the power goes out. Gas-powered generators can do the trick, but they’re loud, emit smelly fumes, and require a place for storing gasoline safely. They also contribute to climate change. Solar generators, on the other hand, are clean, easy to use, don't require fossil fuels, and are becoming more and more affordable as solar technology improves. They can be particularly useful in emergency situations where other fuel supplies are cut off or difficult to access. Solar generators typically capture the sun’s energy via stationary or portable solar panels that are sold separately, convert it into electrical power, and store it in a battery for later use. What’s the best generator for you? First, estimate how much power you need to run appliances, laptops, and televisions in your home should a power outage occur or for whatever you’ll need to power up while you’re camping, living off the grid, or traveling in an RV. Once you know how many watts you’ll need; consider the other features you want such as USB charging ports and rechargeable batteries. You can avoid blowing your budget by selecting a generator with features that make the unit more efficient rather than more expensive. We researched the market to recommend the best generators that are compatible with solar panels.

What To Look for in a Solar Generator When deciding what solar powered generator is right for you, consider which types of appliances, tools, and devices you need to charge and how often you’ll be without a traditional power source. Here are some other tips to help guide your decision-making. Solar Panels There are three common types of solar panels—monocrystalline panels, polycrystalline solar cells, and thin film, or amorphous crystal panels. They each offer different efficiency levels. Monocrystalline panels are most common and slightly more efficient than polycrystalline cells. Thin film panels are a newer technology and are light, flexible, durable, and more affordable than the others, but about half as efficient as the other types. Sometimes they’re included with the generator and sometimes they’re sold separately. ITEHIL Power Station and solar panels. LLoyd Alter Battery Capacity and Power Rating Solar generators run on stored energy so you’ll want to consider the battery’s capacity (the total amount of electricity stored). You’ll also want to know the power rating (how much power is delivered at a time). A battery with a high capacity, but low power rating typically delivers less electricity for a longer period of time. Battery Type Lead-acid and lithium-ion are the most common options. Lead acid are used to power things like automobiles, while lithium-ion options are often used to run power tools. They’re increasingly used in solar-powered generators because they’re lightweight. While they tend to be more expensive than lead-acid varieties, they typically have a longer lifespan which saves money on replacement batteries and keeps them out of landfills. Charge Controllers In order to regulate the current between the solar panels and the battery, the simplest controllers cut the power when maximum voltage is reached. This isn’t as efficient as models that use three- power point tracking (MPPT). Inverter Converting direct current (DC) from solar panels to alternating current (AC), inverters carry a watt rating to show the maximum output of power they can generate. Pure sine wave inverters are more expensive, but more efficient. But they’re not necessarily a cost-effective option if you only plan on using the generator occasionally. Weight Will you be using your solar generator in your home or on the go? For portability, look for units that are easier to carry and maneuver, and that house parts in a sturdy box rather than as separate pieces. Other Features Note presence of multiple USB ports and AC outlets, replaceable batteries, and LED panels that help you monitor your system when it’s dark. Finally, consider units with warranties and made by companies with a solid solar industry credentials. Frequently Asked Questions What size solar generator should I get? When determining the size of generator, you’ll want to look at output measured in watts, as well as storage capacity measured in watt hours (Wh). As a general rule of thumb, generators with under 1000 Wh can keep electronics charged, and are great for camping. To power many devices in your home for longer, you’ll want a large generator with around 1500 Wh capacity. To determine exactly how many watts you need, figure out the devices you want to plug in at once, how many watts they draw, and add it up. An average household refrigerator requires 100 to 400 watts. Most devices manuals will say how many watt they require) or use this handy calculator offers info on the watts needed to power other commonly used items.To determine the number of watt hours you’ll want, take the total watts and multiply it by the number of hours you want to keep those devices charged. For example, let’s say you want to keep a 25 watt cell phone and a 60 watt laptop plugged in at the same time:25 watts + 60 watts = 85 watts of output total If you want to keep those devices charging and in use for five hours:(25 watts + 60 watts) x 5 hours = 425 watt hours (Wh)So, in this case you’d want a generator with at least 85 watts of output and 425 Wh of capacity. When in doubt, round up. For another way to calculate your needs, you may find this explainer from the manufacturer Jackery helpful.Keep in mind that most solar generators do not connect to your home’s electrical panel, so they won’t power hard-wired devices like your hot water heater or ceiling lights; for that type of power you’ll want to consider a home battery system. How many years will a solar generator last? Solar generators should last at least 20 to 25 years. Many manufacturers offer warranties that cover repairs and replacements should anything malfunction within the first few years of use. How much do solar generators cost? Most high-capacity solar generators cost between $1000 and $2000. Generally speaking, larger generators cost more than smaller, portable devices. The generators on the list range from between $140 and $3,400 without taking into account sales or discounts. Why Trust Treehugger?
