Portable Solar Panel Buying Guide

Deciding what portable solar panel to buy can seem overwhelming especially if you have never bought one before. Fortunately, choosing what to buy is easier than you think. It all comes down to knowing what you will use the solar panels for.

What Devices and Appliances Will You be Using on the Solar Panel?

Will you be using it to charge mobile phones, tablets, LED lights, maybe a radio, GPS or a laptop? Portable solar panels can handle that, though not all at the same time and only for limited periods. It depends on the size (watts) of the solar panel. Of course you can always increase the power by chaining multiple solar panels.

How Long Will You Use Each Device?

The more appliances and devices you want to run simultaneously and for long periods, the more power is required.

If you’re going to camp for a couple of days and charge only a phone, laptop and lights, a 100W+ solar panel will be fine. If you’re going to camp for 3 days or more and run several appliances, you have to calculate how much solar power you need.

There are solar calculators available, but it’s easy enough to do it yourself.

1. Add the total number of watts used by each device you will use.
2. Multiply each device watt total by the number of hours you expect to use them.
3. Add the total and that should give you an idea what solar panel size you need.

If you’re a heavy solar power user, you’ll need a battery to pair up with the panel. With a battery you can still run your devices even when the sun goes down. You should get more power than your computations show you’ll use, just to be safe.

To find out what battery size you need, go on a trip in your RV. Run all the appliances like you normally would. Check how long it takes before the battery needs to recharge (for lead acid that is at the 50% level, for lithium ion it is 35-40%).

If your 100 amp hour battery runs out, you need 200 amps to last a day. Remember you’ll only get to use 50% of its capacity (for lead acid), so get extra power.

How Important is Portability to You?

If you’re a backpacker, there are plenty of solar panels that weigh less than 5 lbs. A flexible solar panel is a good option as you can fold and carry it like a briefcase. You can also strap the solar panel on your backpack and it will charge as you hike. For hikers and backpackers, there are a lot of options you can buy. Since you’re likely to carry only a few gadgets, power isn’t an issue.

If you have an RV, the best option is to install 100W to 200W solar panels on the roof. This provides your vehicle with plenty of power to run several appliances without taking up space. These panels are also suited for emergency power.

A flexible solar panel is preferable for backpackers, but for RVs it is not required. RV solar panels should have aluminum or steel frames, waterproof, corrosion resistant and not too heavy. There are portable solar panel kits for RVs that include the inverter, controller and other necessary components. The battery needs to be purchased separately.

How Long is the Charge Time?

Solar panel efficiency ratings range from 17% to 25%. The higher the rating the better the output. But rating isn’t the only factor as size (in watts) matters. The higher the wattage the more powerful the solar panel is. Portable solar panels usually max out at 300W but you can link multiple panels for more power.

All solar panels can produce sunlight during the summer, but during cloudy days, that’s where quality solar panels distinguish themselves. High quality solar power systems can still produce electricity though not at the same level during sunny days. That’s why you have to buy solar panels with solid specifications.

What Features to Look for in a Portable Solar Panel

The following are some of the most important features you may want to consider before buying. Remember that it all comes down to what you need.

• USB Ports: the solar panel should have at least one USB port to charge your phone, laptop or other USB compatible device.
• Weatherproof: you’ll be exposing the solar panel to different kinds of weather, so it must be prepared for it.
• Waterproof: waterproof / water resistant is essential if you’re going to use the solar panels in a boat or anywhere near rivers, streams or bodies of water.
• Kickstand; a solidly built, adjustable kickstand makes setting up easy.
• MC4 connectors and wires: the package should include all the required connectors, wires and cables.
• High Efficiency Rating: the higher the rating the better.
• Flexibility: this is optional. For hiking and backpacking it definitely helps. If you have a vehicle it may not be as necessary but it’s still convenient.
• Warranty: the longer the warranty, the better.
