What Is a Solar Generator?

Solar generators absorb sunlight through solar (PV) panels, and the balance of system converts the solar power into AC (household) electricity. The electricity is stored in a solar battery. The electricity storage (Wh or kWh) and AC power output (W or kW) capacity determine what kind of appliances and devices you can run — and for how long. 

Generators that use photovoltaic (PV) panels tend to operate in similar ways, but not all solar generators are created equal. 

There are substantial variations, all of which should impact your purchase decision.

The most crucial factors include:

  • Electricity storage capacity (wH/kWh)
  • Maximum power output (watts/kilowatts)
  • Solar input capacity (indicates how many solar panels you can connect)
  • Charging methods (in addition to solar)
  • Recharge times (using solar panels and other charging methods)
  • Solar battery chemistry
  • Quality
  • Lifespan
  • Weight and size
  • Price

What To Consider When Buying a Solar Generator

Before purchasing a solar generator, there are numerous crucial factors to consider to ensure you get the right model for your needs and the best value for your money. 

Purchasing a solar generator with insufficient storage or AC output capacity can be an expensive mistake. 

Keep reading to learn about critical factors you’ll want to consider when buying a new solar generator.

Battery Capacity

Solar generators have varying electricity storage capacities, typically measured in Wh/kWh. Choosing one that can power the appliances you need, for as long as you need, between charges is crucial.

For example, a smaller model like the RIVER 2 Max with a 160W solar panel is highly compact but only has 512Wh storage. Its small, lightweight build is perfect for backpacking or camping, but you can’t use it to power multiple high-wattage appliances simultaneously. 

If you’re looking for a home backup solution that can run appliances like your washing machine and fridge, consider a solar generator with expandable storage capacity, such as the DELTA Pro with a 400W solar panel

With enough battery capacity and solar panels for electricity generation, you’ll never run out of power when you need it most. 

Battery Type (Chemistry)

Solar generators typically use lithium-ion (Li-on), nickel-cadmium (Ni-Cad), or lead acid batteries to store electricity. 

The most advanced subset of lithium-ion batteries is lithium ferrous phosphate (LFP/LiFePO4). All the solar generators reviewed here — except the DELTA Max — use this leading-edge battery chemistry. 

LiFePO4 batteries can pack more electricity into a confined space, giving a solar generator higher capacity while maintaining its compact size. 

Additionally, LFP batteries support deep discharging and have an exceptionally long lifespan — making them an excellent long-term investment.

LiFePO4 batteries charge fast and require little to no maintenance. EcoFlow’s lithium-iron phosphate batteries can charge from 0-100% in an hour using AC electricity (depending on storage capacity) and in as little as a few hours using solar panels. 

By contrast, lead-acid batteries may take up to eight hours to charge. 

The only advantage of lead-acid batteries is that they’re cheap. But they also require regular maintenance and must be monitored for proper voltage levels and topped up with distilled water to prevent damage or safety hazards

With a much shorter lifespan, greater sensitivity to environmental factors like temperature, and longer recharge times, lead acid gets beat hands down by LiFePO4 on everything but price.

Charging Time

How long it takes to recharge your solar generator depends on the charging method, the wattage of the power source (such as a 400W solar panel), and the battery’s capacity. 

Since larger batteries hold more electricity, they generally take longer to recharge than smaller units of the same battery type.

The fastest recharging method for EcoFlow’s portable power stations/solar generators is to plug into an AC (household) electrical outlet. Fast-charging units like the RIVER 2 series can charge in about an hour (or less) when plugged into a wall outlet.

Solar Charging Time

How long it takes to recharge using solar panels depends on numerous factors — some of which are beyond your control. Here are some of the most crucial:

  • Number of solar panels
  • Rated power output and efficiency of the PV solar panel(s)
  • Solar input (charging) capacity
  • Peak sunlight hours (in most parts of the world, the sun’s highest irradiance occurs from around noon to 3 or 4 pm). Technically, a peak sunlight hour = 1000 W/m2.
  • Temperature: Solar panels actually get less efficient once they get hotter than 25°C (77°C). Extreme cold can also adversely affect efficiency.
  • Clouds/Snow/Rain: Contrary to a common misconception, solar panels still capture energy on overcast or rainy days. However, they may produce significantly less electricity than on a sunny day.
  • Shade and Debris: It’s a best practice to keep your solar panels clean and free of debris (or snow). You should also position panels where they won’t be cast in shade from overhanging trees or other buildings whenever possible.
  • Positioning and Orientation: The direction, placement, and angle at which you install your panels to maximise electricity generation vary by geographical location. In the northern hemisphere, your PV panels should face true south at an angle perpendicular to the sun’s position during peak sunlight hours.

    Optimising electricity generation from solar panels is a science in itself, which is one reason why many people opt to work with professional installers for fixed PV panel installations. One advantage of EcoFlow’s portable solar panels is that you can quickly change the position and angle of the panel to follow the sun throughout the day.

Charging Options

Looking for a solar generator with multiple charging methods is always a good idea. 

Solar power is a reliable method of electricity generation — It’s the fastest-growing source of electricity worldwide! In 2022, solar — and other renewable energy sources like wind and hydro — surpassed coal and nuclear power as generators of electricity. 

Nevertheless, you can’t generate electricity using PV panels at night, and environmental factors (as outlined above) can negatively impact energy production.

Ideally, you want a unit you can recharge via an AC outlet, a car adapter, USB-C charging, and solar panels — just like all the solar generators reviewed here.

Additionally, DELTA Pro is one of the only portable power stations supporting EV charging, meaning you can recharge at any of the thousands of EV stations nationwide. 

AC Power Output — What Appliances Can You Run?

Every family’s electricity requirements are different. The average UK household consumes just over 2,900 kWh to 3,731 kWh a year (about 8-10 kWh per day). But you may use much more — or less. 

How much power output you need in a solar generator also depends on your use case. If you want an off-grid power supply for camping, your electricity needs will be much lower than if you want to run your whole house.

If you’re looking to take your home completely off-grid, you can get a ballpark estimate of your consumption by averaging out a year’s worth of electricity bills. Electricity consumption tends to vary widely from month to month, so just looking at one bill is not a great idea.

However, a better way to do it is to calculate the total wattage of all the devices and appliances you want your solar generator to run. If your primary goal is home backup power, you may only need to run essential appliances — like a refrigerator and stove — during a blackout. 

Here’s how you do it…

  1. Identify the wattage requirements of your appliances. Survey the starting and running wattage requirements of the appliances and devices you plan to plug into the generator. You can usually find the wattage requirements labelled on the appliance, but we’ve also compiled the starting and running watts of typical household appliances in the table below. 
  2. Convert volts/amps to watts. If your appliance’s power requirements are in volts or amps, calculate an appliance’s running watts with this formula: Volts (V) x Amps (A) = ​​Watts (W)
  3. Count the running watts of your appliances. Add up the running watts of the appliances you plan to use — does the total exceed the running watts listed on your generator? If so, consider buying a generator with more output capacity.
  4. Factor in starting watts (surge power) requirements. Identify the appliance with the highest starting wattage. Add that appliance’s starting wattage to the running wattage total.
  5. Calculate the sum. That final number is the total starting watts you need from your generator. As discussed above, to avoid overloading your generator, do not exceed its starting watts rating.

Peak Power (X-Boost)

As mentioned above, the generator’s peak power output, also known as the starting watts or surge power, indicates the brief burst of extra electricity to get appliances started before settling into the running output. 

Essentially, peak power is the maximum amount of electricity a generator can deliver in a short burst. 

If starting watts are noted on your appliance, the electricity required to turn the device on is higher than the running watts. Devices with electric motors, such as refrigerators, washing machines, or air conditioners, typically require additional power to start. 

If you need to run high-wattage appliances like dishwashers or HVAC systems, make sure your generator’s peak power exceeds the starting watts required to get the device up and running. 

EcoFlow’s solar generators all come equipped with proprietary X-Boost technology, enabling them to deliver up to double the starting watts of their operating capacity.

Size

Solar generators come in many different sizes. 

The weight and dimensions affect the portability (and often the capacity) of the device. 

If you’re backpacking an 8-mile trail to your campsite, carrying a 100-lb generator on your back doesn’t make sense. 

A lightweight option like the RIVER 2 weighs only 7.8 lbs (3.5 kg) and can easily fit in your rucksack or be carried handheld.

If you’re looking to power multiple heavy-wattage appliances, portability probably isn’t much of an issue. 

In that case, a high-powered solar generator like the DELTA PRO is your best bet. Even at 99 lbs (45 kg), it’s easy enough to move around with the built-in wheels — kind of like a compact but heavy suitcase.

Looking for something in between? 

The RIVER 2 Pro and DELTA 2 are your best bets.

Assembly and Components 

Getting a DIY solar generator system up and running can be challenging, especially for those who aren’t technically savvy. 

You have to ensure that the solar panels and balance of system (BOS) components are compatible. Otherwise, your off-grid solar solution simply won’t work.

BOS components for off-grid solar generators include:

And more… 

Not to mention wiring everything together with the solar panels!

EcoFlow solar generators are plug-and-play. The portable power station includes all the BOS components, so “assembling” your solar generator essentially just means plugging in the solar panels.

Even if you want to connect the solar generator to your home electrical circuit, you can do so with minimal fuss. EcoFlow’s Smart Home Panel pairs with the DELTA Pro(s) to integrate with your home’s existing wiring — enabling you to monitor and control your off-grid power solution from anywhere with an internet connection using the EcoFlow app

Expandability 

Your power needs may fluctuate depending on the occasion. For example, you may want a versatile solar generator for outdoor trips and in-home use.

The RIVER 2 series solar generators are an excellent choice for camping and other off-grid activities, but they’re not expandable. 

With the DELTA 2, you get portability and expandability — up to triple its 1kWh out-of-the-box storage capacity with a DELTA Max Smart Extra Battery.

For a whole home generator, the DELTA Pro starts at 3.6 kWh but is expandable to 25 kWh. The average UK household consumes about 8-10KwH kWh per day, so you may have to pick and choose which appliances to run. 

Adding extra batteries is a cost-effective way to increase storage capacity. Buying an expandable solar generator is a wise choice if you think your electricity consumption may increase.

FAQs

If you want to learn more about solar generators, we’ve compiled a handy FAQ to help you better understand which one to get. 

Is It Worth Getting a Solar Generator?

Solar generators are an excellent long-term investment — both financially and for the future of our planet. Over the long run, a solar generator can save you a substantial amount of money on your electricity bills (or eliminate them altogether). Once you reach the end of the solar payback period, you’ll see a substantial return on investment. 
Additionally, there are many government tax breaks and incentives for switching to clean, renewable solar power. The upfront cost can be steep, but with generous tax credits and easy financing options, it pays to make the switch.

What Size Solar Generator Should You Get?

When people ask about “size” in reference to generators, they’re usually referring to power output (watts/kilowatts and storage capacity (watt-hours/kilowatt-hours). In that context, the “right size” solar generator almost entirely depends on how much electricity you wish to consume. 
Tally up the wattage requirements of the devices and appliances you want to run simultaneously and make sure you get a solar generator with an AC output (W/kW) that meets or exceeds your needs. 
Estimate appliance run times between charges to estimate your battery capacity requirements (Wh/kWh). To be safe, choose a solar generator with at least 10% more output and storage capacity than your estimated consumption.
Depending on your use case, “actual” size and weight might also be a concern. Balance your desire for portability against your electricity consumption requirements.

How Many Years Does a Solar Generator Last?

Solar generators and solar panels can last for 25 years or more. Solar battery chemistry significantly impacts the lifespan of your portable power station or other balance of system
LiFePO4 batteries last up to 10 times longer than lead acid batteries — which also require regular maintenance.
Ultimately, how long your solar battery lasts depends on how — and how much — you use it. 
All currently available battery types diminish in efficiency as you discharge and recharge them while operating. Li-on battery types, like LiFePO4, just degrade much more slowly. 
EcoFlow portable power stations are warrantied for five years, and you can expect up to 10 years of use (or more), depending on your usage patterns.

Is There a Limit To How Many Solar Panels You Can Add To a Solar Generator?

Yes, there is a limit to how many solar panels you can add to a solar generator. The solar input (or solar charge) capacity determines the maximum number of panels you can connect to your portable power station or balance of system
If you exceed the input wattage, at best, you won’t generate any additional electricity. At worst, you can damage your system — and throw away money on PV panels you can’t use. Or you can upgrade to a solar generator with a higher solar input capacity.

Can Solar Energy Power Your Whole House?

Yes, you can run your house on solar if you have enough solar panels, storage, and output capacity to satisfy your electricity consumption needs. 
EcoFlow’s Smart Home Ecosystem allows you to run your entire house on solar energy.
