The country of origin, durability, efficiency, and panel type determine the final cost of a solar panel. According to a survey we conducted of 1,000 homeowners who use solar energy, Cost of solar panels Between $15,000 to $20,000 on average per home.
country of origin
The cheapest solar panels come from China, says Tatiana Boronnikova, business director and senior editor at A1 solar shop. “The most popular Chinese brands with cheap panels are Jinko Solar, Trina Solar, JA Solar and LONGi Solar.” In contrast, she noted, panels from North American brands are slightly more expensive, including Silfab, Mission Solar and Canadian Solar.
A difference in cost usually means a difference in warranties. “Chinese panels have shorter product warranties – typically, 10 to 15 years, with 12 years (standard),” she added. North American panels may also offer better performance. “Expensive panels tend to have better conversion efficiency.”
durability
Higher-end brands like Panasonic and SunPower have design features that make their panels more durable, but they’re also more expensive. For example, Panasonic panels have an aluminum frame that can withstand 210 mph winds, and SunPower panels have a copper core that makes them crack-resistant.
efficiency
If you have limited roof space, High efficiency panels Such as those offered by SunPower will help you increase the power output of your solar power system and reduce the number of panels you need. However, high-quality, high-efficiency panels are usually more expensive, and getting the most efficient panels on the market is not necessary if you have ample roof space. Making sure your solar panels are routinely cleaned and maintained can also help improve the efficiency of your system.
Plate type
There are three main ones Types of solar panels: monocrystalline, polycrystalline and thin films. Monocrystalline panels are the three most popular, efficient and long-lasting panels. It is also the most expensive. However, because polycrystalline panels and thin films are less efficient, polycrystalline panels are usually reserved for large commercial installations where roof space is not a limiting factor, and thin films are mostly used for smaller applications such as boats and recreational vehicles.
