Why You Shouldn’t Buy Cheap Solar Power Panels

Solar panels make up a substantial chunk of the financial investment when it comes to installing a solar power system at your home or office. Naturally, you’d expect a certain amount of reliability and performance satisfaction from your investment. With the solar panel industry becoming an ever-expanding sector in the realm of renewable energy, there are several manufacturers to choose from. While some deliver top quality panels that are destined to exceed your expectations, there are some players in the industry that are essentially trying to rip you off by overselling poor quality solar panels. To avoid potential headaches and imminent financial loss, it is important to understand the risks involved if you opt for cheaper, low-quality solar panels.


Solar panels are made up of individual photovoltaic cells soldered together in series and parallel. Manufacturers of low-quality panels pay little to no attention to the quality of these soldered connections. A single poorly soldered connection can become a point of high resistance, generating sufficient amounts of heat to practically burn that part of the solar cell. These burned spots are known as hotspots. The hotspot not only significantly reduces the performance of the overall solar installation, but also poses a fire risk as well.


Micro-cracks are a result of poorly manufactured solar cells, poor handling of the panels during installation or carelessness during a solar panel service. These cracks impact the performance of the solar panels by a significant percentage and, in some cases, it might require you to replace the whole panel. To avoid such inconvenience, make sure that the manufacturer uses Grade A solar cells and that the packaging of the panels is reasonably sturdy.

Internal Corrosion and Delamination

The way poor quality solar panels are constructed could lead to moisture penetrating the PV module. When this moisture interacts with the internal components of the panel, corrosion occurs. Poor production practices can also lead to delamination, which further reduces the performance of the solar panels.

Structural Damage

The utmost priority of the manufacturers of poor-quality solar panel manufacturers is to use poor quality materials in the construction of the panels to maximize their profits. This includes low-grade aluminium for the frame of the panel and thin, weak glass panels for the front of the panel. This means that the glass is prone to cracking when it hails or something impacts the panel, warranting the need to replace the whole panel.

Warranty issues

Cheap, low-quality solar panels are usually manufactured in under-regulated commercial environments where quality control and customer service are hardly a priority. Though they might, at first, seem appealing with their catchy logos, false certification and warranty claims, and too-good-to-be-true prices, when it comes to claiming the warranty, you’d find yourself stranded at the end of your phone line. Dodgy installers usually oversell such panels to innocent, unsuspecting customers by claiming false warranty periods and other misleading jargon. So it is really necessary to do some research on manufacturers before committing to the installers.

It is also advisable to contact locally based, solar panel installers in Brisbane if you are thinking about installing residential or commercial solar.
