There are three types of solar panels used in residential buildings: monocrystalline, polycrystalline, and thin film. Below we provide an overview of each type.

Monocrystalline (mono) panels: Monocrystalline solar panels are the most common. Although these are the most expensive options, they offer the best long-term benefits. They have the highest average efficiency range of 15-20% and the longest service life of 25 years or more. Monocrystalline panels are black and easily fit into most roofs.

Polycrystalline panels: These panels are a cheaper alternative to mono panels, but they are less efficient. They have an average efficiency of 15-17% and can last up to 25 years. Polycrystalline plates are blue, which makes them easier to spot. Because of their lower efficiency, you may need more polycrystalline panels to run your home efficiently.

Thin film panels: These panels offer the lowest efficiency of 7-11%. They work best in homes that cannot handle the extra weight of conventional solar panels. Their installation is less labor-intensive, which reduces installation costs. However, they are not as durable as other types of panels and usually last 10 to 20 years. As the name suggests, these are thin sheet metal plates and can be blue or black.

Country of origin, durability, efficiency and panel type determine the final price of a solar panel.

According to Tatjana Boronjikova, business manager and senior editor at A1 SolarStore, cheaper solar panels come from China. “The most famous Chinese brands with cheap panels are Jinko Solar, Trina Solar, JA Solar and LONGi Solar.” In contrast, he noted, panels from North American brands are slightly more expensive, including Silfab, Mission Solar and Canadian Solar.

The difference in price usually means a difference in warranties. “Chinese panels have a shorter product warranty – usually 10-15 years, and 12 years is [standard],” he added. North American panels can also offer better performance. “Expensive boards have better conversion efficiency.”

Top brands like Panasonic and SunPower have design features that make their panels more durable, but also more expensive. For example, Panasonic panels have an aluminum frame that can withstand winds of 210 mph, and SunPower panels have
