Buyer’s Guide

Now let’s delve into the buyer’s guide to help you make an informed purchase. The choice of the best solar powered generators can be daunting among hundreds of products on the market. This buyer’s guide should help you stay alert to avoid regrettable purchases.

What makes a good solar generator?

Choosing a solar-powered generator that fits your needs should be done with a sharp eye. There are many factors to take into account, and these include the output, battery capacity, size and weight, warranty, and the types of solar panels.

Generator’s Output Vs. Battery’s Capacity

Output, measured in Watts, refers to the maximum power that the generator can output at once. A 400-Watt generator, for example, is more powerful compared with a generator of 300 Watts. Simply put, you can charge 80 iPhone devices with the 400-Watt generator. In contrast, a 300-Watt generator can charge 60 iPhone devices altogether. An iPhone charger delivers 5 Watts (5 volts at 1000 mA).

On the other hand, the capacity of a battery, measured in Watts-hours, is the maximum amount of energy it can store. For instance, a 400 Watts-hours battery (fully charged) can power 40 light bulbs of 10-Watt each, for one full hour, 20 light bulbs for 2 hours, etc.

You may have wondered, why bringing up both factors in one place?

Well, since we’re talking about solar powered generators with built-in batteries, it makes sense to consider both.

Let’s pick two generators from our list;  Goal Zero Yeti (Buy it on Amazon)  versus Chafon Portable UPS Generator (Buy it on Amazon). If you need to use one as an emergency backup, then Chafon, with 500 Watts and 346 Watts-hours, is your best bet. In other words, the power outage may not last for days and your only concern is to power as many devices as it can. Conversely, Goal Zero Yeti, with 300 Watts and 400 Watts-hours, is capable of powering much time longer but fewer devices than what Chafon can deliver. For this reason, Goal Zero is perfect for outdoors and camping while Chafon is considered as an emergency backup generator.

It’s worth noticing that some customers would prefer one solar-powered generator over another. Others might complain about these generators. In fact, they are not aware of what best fit for their needs. As a result, they fell victims paying for products which are not up to their expectations.

Size and Weight

If you plan on traveling with these solar generators, then you should consider the size and the weight. There is no standard size or weight, but your instincts should help you select the right size and weight. These parameters define the portability of the generator. Also look for other convenient features such as wheels and the handles or the foldability of the generator.


Warranty is also an important factor to look at. It helps to know how long the company sticks with you while experiencing some faults. The minimum warranty as seen in our products is 12 months. The solar panels, however, should come with longer warranties depending on the brand. On average, their performance lasts for 25 years.

Types of Panels

Many of these solar generators come with built-in solar panels. Nonetheless, some can be replaced. Others give you the flexibility to actually buy your favorite solar panel. In your purchases, take note of the types of solar panels, viz. mono-crystalline, thin film, and polycrystalline. In order of efficiency, mono-crystalline comes first, followed by poly-crystalline then lastly the thin film.

Battery Capacity

The crux of solar powered generators is the battery capacity. The higher the capacity is the more devices to power. The capacity of these batteries is measured with watt-hours And the choice of the capacity is often influenced by the types of devices to charge. In some generators, you can expand the number of batteries or replace the provided one.

We expressed our dissatisfaction in a little warranty of 1 year for Goal Zero solar panels and battery’s warranty of 6 months. But, considering that the generator requires little maintenance, this shouldn’t be a deal breaker to replace the components while enjoying a sustainable energy.
