When I bought my first solar panel set three years ago, I knew nothing about them. You stick them in the sun, and they make electricity. I was clueless about cost, equipment needed, how to hook the solar panel to the battery storage. Nothing, I knew nothing.

Luckily, the clerk at my local hardware store was very knowledgeable. He told me what equipment I needed and explained how to connect everything. He also made sure that the system I bought would do what I needed it to do: power my Keurig coffee maker during an eight-day rustic retreat. That solar panel purchase was one of the best things I ever bought for camping. Ah, blessed coffee!

Essential Facts About Solar Panel Sets

Before understanding solar panel functions, it helps to learn some of the words that you will frequently hear during the entire process. Rather than explain volts, watts, and amps, this short video explains them well:

How a solar panel works

By collecting photoelectric light, a solar panel set can convert the power of the sun into usable electricity. But how does the entire process work?

The first step is the collection of sunlight. Photovoltaic (PV) cells collect, or capture, the energy from the sun. Next, as the photons, or particles of light, reach the solar cells, that energy is absorbed by electrons. Through the interaction of the photons and electrons, a difference in voltage occurs.

Because solar panels create energy known as direct current (DC), and standard appliances use alternating current (AC), a conversion process must take place. This mechanism requires a power inverter. In a portable solar panel system, the charge controller regulates how fast the batteries fill up. Appliances plug directly into outlets on the power inverter.

What equipment does a solar panel need?

So, you now know the basics of how solar panels collect and convert energy. The equipment necessary to perform this function is relatively simple. You can purchase entire sets that are ready for use. You can also buy separate components to configure your system.

The components needed are:

  • Solar panels
  • Inverter
  • Net meter (for home-based systems)
  • Charge controller (for off-grid systems)
  • Storage battery or batteries
  • Wiring and cables

Solar panel configurations can be one single panel or a series of connected panels. They can utilize one 12V deep cycle cell or a set of batteries linked to store energy.

Price Range for Basic Solar Panel Kits

Pricing varies depending on your needs. If you are purchasing just the solar panel, your cost will be less than if you need all the components for a complete assembly.

Pricing for individual 100-watt solar cells with connectors generally ranges from $100 to $200. Some of these panels have charge controllers installed while some have plug-ins to connect them.

Pricing for simple controllers begins at around $15 to $20. Controllers with higher rated capacities start at $50 and can go up to several hundred dollars.

Small power inverters with one or two AC outlets and a couple of USB outlets start at around $50 to $70. These are fine for most applications during camping use. If you need more, larger inverters can cost anywhere from $100 to $500.

A 12V deep cycle marine lead-acid battery will range in price from $100 to $300. You can pay more for a lithium storage battery, but please research them thoroughly as they are not all the same. Determine how many cells you need in your set and budget appropriately.

A pre-assembled kit will cost from $300 to well over $1,000. If you purchase one, make sure that all the components will produce the amount of power you need. They say that something is only as good as its weakest part, so it makes sense to conduct due diligence.

Finding the Best of the Best: How We Reviewed

When we reviewed solar panel sets, we researched many units that didn’t make our list. Our research included what components the kit had, how powerful it was, customer reviews, and professional ratings.

Most of the items presented are just solar panel assemblies, but one is a complete kit with all the components included. Determine your needs before spending great gobs of money. While more is usually better, in portable solar power units, just enough is often enough.

Top Portable Solar Panels

Based on our research and personal experience, we compiled what we consider the best solar panel kits for your money. Before you shop, determine what you want your rig to power.

All appliances should have a usage label that tells you how much power they need. A coffee pot will draw more amperage during the brew cycle than just keeping the pot warm.¬†Cell phones, computers, tablets, and other smaller electronics don’t need a lot of power. Once you know this, you are ready to shop.

1. Renogy 100 Watt 12 Volts Monocrystalline Solar Panel

This product includes only the solar panel with no extras. You will need separate items to construct a camping solar power station. It provides up to 100 watts of power. With a junction box and MC4 leads on the back, it is easy to connect a charge controller or other solar collectors. At prices ranging between $110 and $135, it is affordable.

One of the downsides to this panel is that it does not have a stand. It does, however, include pre-drilled holes for easy mounting. Customers who left poor reviews mentioned problems with shipping and receiving damaged items or mismatched panels from separate orders. Others with complaints about the product say that the rated power of 100 watts doesn’t match the actual, which often measured under 50 watts.

This product received very high marks on the Renogy site at 4.9 out of 5 stars. This panel is also available at local retailers, which makes it appealing if you can’t wait for shipping. Look at local chains like The Home Depot.

Because this unit is just the solar panel, you would also need to purchase a charge controller, power inverter, and storage battery to use this completely off-grid. This panel would need to be mounted to provide an angled face for maximum solar absorption.

If you need replacement solar panels for an existing system, this is an outstanding choice.
