Solar panels have been a renewable energy option for homeowners for decades. But technology advancements have made the best solar panels a reliable and cost-saving asset to many homeowners. When it comes to choosing the right solar panels for your lifestyle, there are a lot of factors to consider, but our top recommendation is the Renogy 400-Watt 12-Volt Off-Grid Solar Premium Kits— a durable option with impressive energy output.
Nature Power’s 440-watt kit features four 110-watt panels, along with a 750-watt power inverter, a ... [+] 30-amp charge controller and wiring to get your home up and running on solar energy.

If you’re installing these panels yourself, you’ll need to have at least some level of technical know-how. If you’re relying on someone else, “you want to know who will be installing the project, how long they’ve been around for and are they reputable,” Horwitz says. It’s also important to make sure you have a roof warranty in place, given that the panels are often installed on top of your home and can be heavy, Horwitz says.
From there, you’ll usually invest in the solar panels themselves, which you can either purchase from the company who will be installing your panels or on your own. “You should be thinking about the whole system, and that includes batteries [to store your excess solar power] and panels,” says Muhammad Ashraful Alam, Ph.D., a professor of electrical and computer engineering at Purdue University. Not all panels are alike or even work for every home or climate, making it important to consider your personal needs when choosing panels, Alam says.
It sounds like a big effort—and it is. But while solar panels are a big financial investment for your home, federal and state tax credits can dramatically lower the cost of your project. Consider this expertly curated list of the best solar panels in your switch to solar energy.

Grape Solar’s 200-Watt panels are made of monocrystalline (a single piece of silicon that makes it easier for electricity to flow through) and designed for residents with smaller roofs, like cabins. At 28 x 62 inches, the panels are on the more petite side, allowing you to fit a few on your roof. These panels have 0 to 3% positive output power tolerance, along with multilayer sheet lamination to enhance cell performance over time. It’s also designed to work in weaker light conditions, as well as high temperatures. This panel can hold up to 50 pounds per square foot of wind and snow, making it a good choice for a range of climates, plus built-in mounting holes make it easy to install.

With a 100-watt capacity, the Topsolar Solar Panel Kit isn’t your best bet for serving the power needs of a large home. But it’s a good choice for powering up RVs, boats, vans and smaller residences, or for experimenting with solar power to see what you do and don’t like. The kit has all the elements to get you set up, including Z mounting brackets, cables and a controller. The panels have pre-drilled holes for easy installation and are designed to stand up to higher winds and moderate snow loads. Keep in mind that, while this particular kit is 100 watts, Topsolar also has panels that go up to 340 watts to give you options.

Choosing the best solar panels for your needs, whether it’s your home or to enhance your camping experience, requires some thought and planning. To choose the best options on the market, we consulted with four solar energy experts—including some who have been through this process as consumers—for their input on the best materials to look for in solar panels, as well as ideal features and considerations.
From there, we looked at the top solar panels on the market and narrowed the field by output, construction, durability and value. Reviews from real owners were also taken into consideration to ensure we had the best sense of how these panels perform across a range of homes and needs. Only solar panels with average reviews of four or more stars were featured.
Solar panels all have a specified performance. This is typically listed in terms of wattage (the electrical output they can provide for your home), along with efficiency (the percentage of sunlight they can turn into power). The right performance for your solar panels depends on what you’re using it for. If you want portable panels that can juice up your phone and operate a hot plate while camping, you’ll need a lower performance than if you’re planning to power your home with panels.
Durability is important in solar panels, given that they’re an investment. Many panels have built-in technology to protect the panel’s cells (which actually convert sunlight into energy), along with sturdy frames. However, the manufacturer will often state what kind of load these panels can support, usually in the form of wind and snow. You’ll want to ensure that the panels you choose make sense for the climate in which you plan to use them, as well as your needs.
Whether you’re relying on solar panels for your main energy source or are using it to supplement more traditional forms of energy, it’s important to have panels that are reliable. Most solar panels will have a warranty that allows you to return them for a refund if they’re not working as intended. However, elements like cloudiness and shade can influence how well they work. If direct light is limited, consider investing in panels that use half-cell technology—this helps harness more power, even in dimmer conditions.
It depends. Solar energy for your home tends to cost a significant amount of money upfront. “They don’t save you money right away,” says Paulina Jaramillo, a Ph.D. energy fellow at the Wilton E. Scott Institute for Energy Innovation at Carnegie Mellon University. “But the market is increasingly competitive. When you add the subsidies that are available and consider the cost over a lifetime, they make economic sense.” Some energy companies have what’s known as a “buyback plan,” where solar panel owners can sell excess electricity they create back to the electric grid, explains Daniel Richmond, senior manager of Cross Serve and core product development at renewable energy company Green Mountain Energy. These can allow you to get a good financial return on your investment, especially if you generate more energy than you use.
There are mainly four different types of solar panels to consider. Monocrystalline panels, which are black, are considered the most efficient type of panel. As a result, you’ll need less panels to generate as much electricity as other types, Alam says. “These are considered the Rolls Royce of solar panels,” he adds. “They’re very reliable and are easy to maintain, but they’re more expensive.” Polycrystalline solar panels have a blueish tint and are less efficient than monocrystalline panels. “They’re also lower in cost,” Alam notes. Thin-film solar cells are less efficient than the others, but they may be helpful for smaller projects. “They’re more flexible, but the cost is lower and they’re easy to install,” he says. Solar shingles are also becoming popular, Alam says. “They’re completely flexible and embedded in the shingles to do the same function as a panel,” he says. These tend to be less efficient than monocrystalline panels, but have a better aesthetic, Alam says.
There are a lot of potential uses for solar panels. These handy tools can generate power for you when there is no plug in sight, like at a campsite. But they can also create energy when your power source is unreliable or when you want to make your own. “If you’re someone that is dealing with reliability problems—say, you have storms and the power goes out—solar panels with battery storage can give you increased reliability,” Jaramillo says. But home installation is typically a big investment, and it’s not something you’ll typically see a return on for a few years, Alam says. Local legislation can also be a factor. “The economics vary depending on what state you're in,” Horwitz says. Overall, though, experts agree that solar panels will save you money over time. “It’s a big investment and a good investment,” Horwitz adds. “Some homes have a better valuation having had solar energy.”
