There are many solar products available beyond the traditional 60 or 72-cell panels used for rooftop, ground-mounted, commercial, and utility-scale solar panels. For solar shoppers looking for small solar panels, we’ll walk through some of the options available.
Small solar panels for sale
We’ll go over some small solar panel products further below, but first, what are generally your options when it comes to buying and installing “small solar panels“?
If you’re searching for solar panel manufacturers online, you’re likely going to come across a few categories of companies. First, there are manufacturers who specialize in panels designed for residential, commercial, and utility-scale solar projects. These companies (like Panasonic, LG, SunPower, and many more) are usually large, international manufacturers and they make the vast majority of solar panels you’ll see on rooftops and on solar farms. Panels from these companies are usually purchased by solar installers, who then complete installation projects with them.
Second, there are manufacturers like Renogy and Solartech who make more DIY-focused solar panels. These companies often make solar panels that have lower wattages and can be bought easily online from wholesalers by individuals looking to install solar themselves, without an installation company. If you’re looking for “small solar panels” available for purchase to use in a DIY home solar setup, you’re likely best off going with products from companies like these. You can normally buy small solar panels from online stores including Amazon and eBay. Traditional panels from large manufacturers like Panasonic have to be purchased through a distributor or as part of a solar panel installation from a solar installer.
How are small solar panels different?
Small solar panels are physically smaller and produce much less electricity than traditional solar panels. As such, they are most often used in off-grid or portable energy applications. Most manufacturers who produce traditional solar panels do not also produce panels of smaller sizes. Smaller solar panels can be used in many different ways: as a phone charger, for RVs and during camping trips, and for small off-grid solar projects.
If you’re looking to save money by offsetting your home energy use with a solar power system, small panels likely won’t get the job done. In order to generate the electricity needed to power all of your appliances, the best option is to get quotes for a solar system installation that produces much more energy than smaller panels can.
Types of small solar panels
There are two general product categories you can choose from if you’re looking for small panels: low-wattage solar panels and portable solar gadgets.
Low-wattage solar panels
Typically, solar panels used in rooftop and ground-mounted installations are between 250 and 365 watts (W). Panels of 100W and lower are available for purchase from many companies and can be a good solution for small-scale electricity generation projects. For example, using one or more 100W solar panels to provide electricity to a boat or motorhome is a great way to keep electrical appliances and batteries charged up on the go using the sun’s energy.
Low-wattage panels come in several sizes, from around 10W up to 100W. Panels larger than 100W will begin to have more similar dimensions as standard residential solar panels. Here are just a few small panel options you can purchase:
There are several other essential components that you’ll need to have set up in order to generate and use electricity from a small panel. In addition to the panel or panels themselves, you’ll require a solar charge controller, an inverter, and a battery backup system. Solar panels don’t produce usable electricity independently, so you can’t simply plug in an appliance to a panel to power it.
Setting up a functional off-grid solar energy system like this means working with wires and electrical components. Unless you have experience working with photovoltaics and electrical systems, it may be worth your time to hire a trained electrician to set your small panels up for energy generation. When it comes to larger, grid-tied solar panel systems, it’s always a safe bet to hire a certified solar installer to get the job done.
Portable solar gadgets
The second type of smaller solar panels is the general category of solar gadgets. This could include anything from portable phone chargers to solar-powered speakers, keyboards, backpacks, and more. In general, gadgets like solar phone chargers are much smaller than a solar panel, usually handheld or even foldable for easy transportation and use.
There are tons of portable solar gadgets available, so here are just a few examples of what you might find:
Unlike low-wattage solar panels, portable solar gadgets are all-in-one systems, meaning you won’t need to buy and set up charge controllers, batteries, and extra wiring to use your gadget. All that you need to operate a solar phone charger is some sunlight and a low-charged mobile phone.
Solar panel size: what are typical dimensions for solar panels?
Small panels vary in size based on their wattage. On the lower end of the wattage scale, panels can be close to 1 foot by 1 foot, and most 100W solar panels tend to have dimensions of about 2 feet by 4 feet.
Most often, residential solar panels (250W to 365W) are around 5.5 feet by 3.5 feet. Larger, commercial and industrial-scale panels have extra solar cells and can be closer to 6 feet long.
