The Best Solar Panels Options

Types of Solar Panels

There are three primary types of solar panels: monocrystalline, polycrystalline, and thin film. All solar panels capture the sun’s rays and convert them into electricity, but each type differs slightly.

Monocrystalline Solar Panels

Monocrystalline panels are manufactured from a single (mono) silicon crystal, and they’re easy to identify because they’re dark black. This single-crystal technology is highly efficient and compact, meaning smaller monocrystalline panels can produce more energy than other types of panels of a similar size. Unfortunately, monocrystalline panels are also more expensive than other types.

Within the monocrystalline category are a couple of varieties, including passivated emitter and rear contact (PERC) cells that increase the panel’s efficiency, and bifacial solar cells that capture sunlight on both sides of the panel.

Polycrystalline Solar Panels

The main difference between monocrystalline and polycrystalline solar panels is that the latter is made from multiple silicon crystals, rather than a large single crystal. This type of panel is less expensive to produce, so it also costs less to purchase.

Another factor that sets these panels apart is their color: Polycrystalline solar panels come with a blue surface rather than a black one. Unfortunately, they’re slightly less efficient, so more of these panels are necessary to generate the same amount of electricity as monocrystalline panels.

Thin-Film Solar Panels

The relatively new kids on the block—thin-film solar panels—do not contain silicon crystals. Instead, they feature a thin layer of a photovoltaic substance such as amorphous silicon or cadmium telluride that is affixed to a solid sheet material. Thin-film panels are lighter in weight and beneficial for creating portable panels.

However, this type of solar panel isn’t all that efficient, and its use is generally reserved for the commercial solar installation industry. Thin-film panels are considered to be more visually pleasing, however, because the other two types of panels have lines running through them, while thin-film panels typically feature a flat, unblemished surface.

What to Consider When Choosing the Best Solar Panels

A solar panel’s wattage can be a top consideration for most buyers, and the best solar panels can vary in strength based on users’ needs. Panels available for charging digital devices and running small appliances such as blenders, fans, and RV refrigerators usually offer an average of 100 to 150 watts.

However, keep in mind that solar panels—unless they’re standalone—must be connected to a battery or to a generator that stores the energy until something is plugged in. The more efficient the solar panel, the more quickly it will charge a battery or generator. This means less time waiting for power to be available to use.


When comparing solar panels, note that the more-efficient ones can convert a higher percentage of sunshine into electricity—this is called the panel’s solar cell efficiency. Not all sellers list their panel’s solar cell efficiency, but there are typical ranges for panel types.

  • Monocrystalline: These popular black panels are known to be the most efficient, topping the list at more than 19 percent solar cell efficiency.
  • Polycrystalline: With solar cell efficiency ranging from 15 to 17 percent, polycrystalline panels are slightly less efficient than monocrystalline. However, they’re often more affordable.
  • Thin film: The least efficient type of all the panels, thin-film options fall below 15 percent solar cell efficiency. They’re also the least expensive.

Efficiency can increase by situating the panel in the best direction for solar panels, typically facing south. It also depends on the panel’s open-circuit voltage (VOC). When selecting a panel, make sure the listed VOC does not exceed the maximum voltage input for the generator or charge controller that will be used.

Temperature Coefficient

Also known as its ability to tolerate heat, a solar panel’s temperature coefficient indicates its relationship between power production and outdoor temperature. It’s the amount of reduced power output for every degree of temperature increase. Therefore, the hotter it is outside, the less efficient a solar panel will be.

Although thin-film panels are the underdogs in many aspects, they’re on top when it comes to temperature coefficient. Thin-film panels experience an output loss of just 0.2 percent. Compare that with monocrystalline and polycrystalline panels that experience output losses of between 0.3 to 0.5 percent.

Temperature coefficient is worth considering if the panels are to be used in a hot climate where summer temperatures are frequently at or above 90 degrees, but unfortunately, the makers of user-friendly solar panels rarely list the products’ temperature coefficients.

Region and Climate

Solar panels can still operate in cold climates because it’s not the sun’s heat that generates electricity but its light. Even in regions that see a lot of snow—as long as the snow is brushed off the surface of the panels—they will continue to produce electricity. Interestingly, when the sun comes out and reflects off the white snow, it creates additional light that can benefit solar panels. This is called the “albedo effect.”

Regions that experience a lot of sunny days are good options for solar panel use. Rainy and cloudy climates reduce the amount of sunlight that reaches the panels, so less energy is produced. However, solar panels will still produce some power on cloudy days, just not as much.


Solar panels don’t come with moving parts, so they’re relatively durable. Of course, they’re not indestructible, so dropping something heavy on a panel could break it. Polycrystalline and monocrystalline panels are thicker and more durable than thin-film panels.

During the developmental phase of solar panel design, manufacturers subject the panels to rigorous tests, then use the results to improve the products. Some of the tests include the following:

  • Damp heat test: This involves subjecting the panels to temperatures up to 185 degrees Fahrenheit and 85 percent humidity for more than a month. This high level of heat and humidity simulates years of outdoor use, and it is helpful to determine whether a panel will withstand years of typical heat and humidity.
  • Thermal cycling: This test exposes the panels to extreme heat and cold in cycles to determine their resistance to environmental stress.
  • Dynamic loading: Solar panels are often subjected to strong winds, so manufacturers test them during the developmental stage using vacuum cups attached to the panel surfaces that exert an alternating pull-and-push force that mimics high-wind situations.
