When you’re comparing solar quotes, there are a few things to look out for to get the best solar panels possible:
|Solar panel type
|There are three main types of solar panels: Monocrystalline, polycrystalline, and thin-film
|The power output rating of a panel describes how much power a solar panel can produce in ideal conditions
|Efficiency rating measures how much sunlight a solar panel can turn into electricity
|19% - 21%
|The temperature coefficient is the rate at which power output drops as a solar panel gets hotter.
|-0.3% to -0.5%/ °C
|A product warranty covers damages to panels caused by manufacturing or workmanship. A performance warranty ensures a panel will perform at a certain level over time.
|12-year product warranty, 25-year linear performance warranty with a 0.50% degradation rate
There are three main types of solar panels: monocrystalline, polycrystalline, and thin-film.
Today, almost all home solar panels are monocrystalline because of their superior performance and comparable cost to other solar panels. Monocrystalline panels consist of solar cells made from a single silicon crystal, allowing electrons to move easily through the cell and increase efficiency.
In contrast, polycrystalline solar panels feature cells made of multiple silicon crystals, limiting electron movement. Due to their less powerful structure, polycrystalline panels are rarely used in modern home solar installations.
Thin-film solar panels, characterized by their construction from thin layers of various materials, are nearly 300 times thinner than conventional solar panels. While their slim profile makes them easy to install, their efficiency is lower, requiring more space to generate the same amount of energy as monocrystalline and polycrystalline panels.
"The power output, or wattage, of a solar panel is the amount of power it can produce under Standard Test Conditions (STC), a lab setting designed for consistent testing. Most solar panels installed in 2023 have a power output between 370 and 400 watts.
When you install high-wattage solar panels, you need fewer solar panels to generate the electricity needed to power your home. The average home needs between 15 and 19 panels to cover its electricity usage, but it will vary from home to home!
Solar panel efficiency indicates how effectively a solar panel can convert sunlight into electricity. Panels with higher efficiency ratings can harness more sunlight, translating into more usable power than panels with lower efficiency ratings.
Today, most solar panels have efficiency ratings between 19% and 21%, offering excellent performance for most homeowners. These panels tend to strike a balance between efficiency and cost-effectiveness.
These high-efficiency panels can generate more electricity in a smaller space, making them ideal for homes with limited roof space. However, it's essential to note that the enhanced performance often comes with a premium price tag. Homeowners considering super high-efficiency panels should be prepared for a higher upfront investment.
The temperature coefficient describes how a solar panel’s output decreases as surface temperature increases. That’s right - solar panels generate electricity from the sun, but they operate worse the hotter they get, but the losses are pretty minimal.
The average temperature coefficient is -0.3% to -0.5%/ °C. For each degree the panel’s surface temperature goes above 25°C, the power output drops by 0.3%.
When choosing solar panels, aim for temperature coefficients within this average range. The lower the temperature coefficient, the better the panels will withstand temperature variations. Panasonic stands out with one of the best temperature coefficients at 0.26%, showcasing superior performance even in changing environmental conditions.
Solar panels typically come with two warranties: a product warranty and a performance warranty.
A solar panel product warranty safeguards against defects that may have arisen during manufacturing. While the average product warranty lasts 12 years, many reputable solar brands now provide extended 25-year product warrantings.
A solar performance warranty outlines how a panel is expected to perform over time. As solar panels age, their power output naturally decreases. The average performance warranty spans 25 years and outlines the rate at which a solar panel degrades, usually 2% after the first year and 0.50% annually for the remainder of the warranty period.
If the panel degrades at a rate faster than 0.50% per year, it won’t produce as much energy as other panels on the market over time. Try and find panels with a degradation rate of 0.50% or lower. Longer product warranties and lower degradation rates contribute to solar panels' long-term reliability and cost-effectiveness, making them an ideal choice for homeowners.
When it comes down to it, many companies today are producing extremely high-quality solar panels that will reliably make energy for decades to come.
What truly matters is choosing the right solar installer. The company you choose is the key player in your solar journey—they'll be on your roof, drilling through shingles, running wires, and the ones you'll turn to if issues arise. Selecting a company that will be around to support you is crucial.
We recommend opting for a local solar company with at least five years of experience, its own crews, and a track record of consistently positive customer reviews. Local installers typically possess a deep understanding of solar in your area, offer fair prices, and provide top-notch customer service.
The trust you place in your installer extends to the equipment they carry. Reputable installers are likely to offer high-quality equipment. If you’ve picked the right installer, you should feel confident in what they’re installing on your roof.

SolarReviews’ team of solar experts has over two decades of experience in the solar industry. Using that expertise, we’ve created a way to rate solar panel brands based on more than just how the panels perform and how much they cost. We also look at the company’s financial performance and its availability. Solar is a long-term investment, so you want to know about the equipment that is accessible, and that is sold by a company that supports you for the long haul.
The value of a solar panel is evaluated by looking at the wholesale cost per watt of a brand’s flagship solar model. The lower the price-per-watt, the more points were awarded.
When comparing solar panels, our team identified panel efficiency and temperature coefficient as two of the most important specifications. Panels with high-efficiency ratings received more points. Panels with the lowest temperature coefficient were awarded more points than those with higher temperature coefficients.
Company financial performance is the best indicator of whether a company will be around to provide customers with support in 25 years. We reviewed available financial statements and profitability, among other factors, to determine overall financial performance.
Investing in the U.S. shows a company’s commitment to the solar industry. Also, consumers are becoming more conscientious of where they purchase goods from. To reflect this, we awarded points to companies with headquarters or regional offices in the United States and points for U.S. manufacturing and attendance at American trade shows and events.
Points were awarded based on the length of both the product and performance warranties, with longer warranties receiving the most points. Performance warranties were also evaluated by degradation rate, with lower degradation rates receiving higher scores.
It doesn’t matter how great a solar panel is if homeowners can’t access it. To reflect a brand’s availability, we reviewed market share data from California’s Distributed Generation Statistics database for solar installations 20 kilowatts or less in size in 2022 and awarded points accordingly.
