What Is Solar Panel & How Long Does Solar Panel Last?

At Constant Energy, we believe in empowering businesses with clean, reliable, and cost-effective solar solutions. But what exactly is a solar panel, and how does it benefit your business?

What is solar panel?

A solar panel also known as a photovoltaic (PV) panel, is a device that converts sunlight into electricity.  Solar panels consist of several key components:

  • Frames: Typically made of aluminum for durability.
  • Silicon cells: The core component that absorbs sunlight and generates electricity.
  • Conductors: Usually copper-based, facilitating the flow of electricity.
  • Polymer-based materials: Used for the back sheet and protective film.

While the manufacturing process may involve some hazardous chemicals, strict environmental regulations can ensure proper handling and disposal to minimize ecological impact. As businesses owners increasingly adopt solar energy, the shift toward sustainability helps reduce carbon footprints and promotes a cleaner future.

How Long Do Solar Panels Last?

According to SolarPower Europe’s ‘Global Market Outlook for Solar Power’ report, the global solar market is expected to increase by 25% to 203 GW in 2022. This is the first time annual PV installations are forecasted to cross the 200 GW level.

Solar panels are a long-term investment in clean energy. According to industry standards, a solar panel can last from 25 to 30 years. However, this doesn’t mean they stop working entirely after this period. Instead, their efficiency gradually declines due to natural degradation.   With high-quality equipment and expert installation, like those provided by Constant Energy, a leading developer of large-scale solar, wind, and battery storage projects across Asia, your system can maintain 80% efficiency or more even after decades of use. This ensures reliable performance, lower electricity bills, reduced carbon emissions, and energy independence for years to come.

How Much Energy Does One Commercial Solar Panel Produce?

The power output of a commercial solar panel depends on several key factors, including system size, sunlight exposure, and panel efficiency. Larger installations naturally generate more electricity, while optimal positioning such as panels facing true south (in the Northern Hemisphere) with minimal shading to ensure maximum sunlight absorption. Higher-quality solar cells also play a crucial role, as they convert sunlight into energy more effectively. For example, a 120kW commercial solar system can produce enough electricity to power a business using 180,000 kWh per year, significantly reducing energy costs while supporting long-term sustainability.

As a leading developer of high-performance solar projects, Constant Energy understands that transitioning to solar power is a major decision for businesses. That’s why we offer a hassle-free Solar Power Purchase Agreement (PPA) and Battery Energy Storage System (BESS), eliminating upfront costs while maximizing long-term savings.
