There are three types of solar panels used for residential homes: monocrystalline , polycrystalline and thin-film . We’ll provide an overview of each type below.

Monocrystalline solar panels are the most common. Although they’re the most expensive option, they offer the best long-term benefits. They have the highest average efficiency range of 15% to 20% and the longest lifespan of 25 or more years. Monocrystalline panels are black and easily blend into most roofs.

These panels are a cheaper alternative to mono panels but are less efficient. They average between 15% to 17% efficiency and can last up to 25 years . Polycrystalline panels are blue, making them easier to notice. Due to their lower efficiency, you may need more polycrystalline panels to effectively run your home.

These panels offer the lowest efficiency rate at 7% to 11%. They work for applications where the base cannot withstand the added weight of standard solar panels, like on RVs , boats and sheds. They’re less labor-intensive to install, reducing installation costs. However, they aren’t as durable as the other panel types and typically last 10 to 20 years. As their name suggests, they are thin sheet panels and can be blue or black.

The country of origin, durability, efficiency and type of panel all determine the final cost of a solar panel. According to a survey that we conducted on 1,000 homeowners with solar, solar panels cost between $15,000-$20,000 on average per home.

The cheapest solar panels come from China, according to Tatiana Boronnikova, Business Manager and Senior Editor at A1 SolarStore . “The most famous Chinese brands with cheap panels are Jinko Solar, Trina Solar, JA Solar and LONGi Solar.” In contrast, she noted that panels from North American brands are slightly more expensive, including Silfab, Mission Solar and Canadian Solar.

The difference in cost typically means a difference in warranties. “Chinese panels have shorter product warranties – usually, 10-15 years, with 12 being [the] standard,” she added. North American panels may also offer better performance. “Expensive panels tend to have a better conversion efficiency.”

High-end brands like Panasonic and SunPower have design features that make their panels more durable, but also more expensive. For instance, Panasonic panels have an aluminum frame that can withstand 210 mph winds, and SunPower panels have a copper foundation that makes them resistant to cracking.

If you have limited roof space, high-efficiency panels like the ones offered by SunPower will help you maximize your solar power system’s energy production and minimize the number of panels you need. However, high-quality, high-efficiency panels are typically more expensive, and having the most efficient panels on the market isn’t necessary if you have ample roof space. Making sure to routinely clean and maintain your solar panels can also help to improve the efficiency of your system.

Temperature coefficient is also an important solar panel efficiency measure, especially if you live in a hot climate. A favorable temperature coefficient is as close to zero as possible, indicating that efficiency doesn’t go down very much in temperatures above 25 degrees Celsius.

There are three main types of solar panels : monocrystalline, polycrystalline and thin-film. Monocrystalline panels are the most popular, efficient and long-lasting panels of the three. They’re also the most expensive. However, because polycrystalline and thin-film panels are less efficient, polycrystalline are usually reserved for large, commercial installations where roof space is not a constricting factor, and thin-film are mostly used for smaller applications like on boats and RVs.

High quality solar panels might be more expensive than other options, but they’re more efficient and come with a longer warranty. Ultimately, that means you can purchase fewer panels to power your home and can rely on your system lasting 25 years or longer.

Although going solar has a high upfront cost , most people who install solar panels on their homes will save thousands of dollars on electricity bills in the long run. However, every solar system is different, and whether or not solar panels are worth it for you can depend on a number of factors.

If one or more of these apply to you, solar panels are likely a smart investment:

“ With home energy costs high and likely to continue increasing in the long and short term, our team firmly believes solar to be a crucial and worthwhile investment,” said Greg Fasullo, the CEO of Elevation Solar . “Not only will you see returns on your installation in the form of lower energy bills and payments for grid services, you’re improving the carbon footprint of your home and increasing its overall value .”

Ultimately, you should speak with a local expert about your energy needs and weigh your options to decide if solar is right for you.

If you have limited space on your roof, we recommend getting higher-efficiency panels like the ones offered by Silfab, SunPower and Panasonic . However, if you’re looking for a value-oriented price point, we recommend panels from Canadian Solar and Trina that offer a good product for the price.

Overall, the solar panel brand you choose depends on your individual home and needs. The solar industry continues to develop increasingly advanced photovoltaic technologies, and there are countless options available. We strongly recommend speaking with a solar professional to discuss what panels and designs will fit best for your roof.
