For over a decade, Renogy has been at the forefront of solar technology, dedicated to providing sustainable, clean energy solutions. Our journey has always revolved around the pursuit of perfection and refining scenarios. With each exploration comes new inspiration, embodying our philosophy of continuous refinement.

Renogy has long employed state-of-the-art C-Si (Crystalline Silicon) technology in our solar panel product line. Now, we're thrilled to unveil a groundbreaking addition: CIGS solar panels.

Let's delve deeper into what sets CIGS panels apart and how they differ from our Flexible Monocrystalline Solar Panels.

CIGS Solar Panel

Renogy 150W CIGS Solar Panel represents a pinnacle of meticulous development, showcasing unparalleled adaptability across various outdoor settings. It emerges as the ultimate ultra-flexible solar panel, boasting unmatched shockproof and pressure-resistant qualities, resilient against severe weather, corrosion, and even microcracks caused by incidental impacts. This 150W CIGS solar panel stands out for its exceptional anti-shading capabilities, delivering remarkable output even in partial shading scenarios. Its 360° flexibility seamlessly conforms to diverse roof shapes, ensuring effortless integration. Furthermore, the adhesive tapes on its back streamline the installation process, minimizing wear and tear, and enhancing user convenience.

Flexibility and Durability

CIGS, short for Copper Indium Gallium Selenide, is a game-changer in outdoor scenarios. Its mind-blowing 360° flexibility and durability redefine installation possibilities. While our versatile flexible monocrystalline solar panels suit 95% of installations, CIGS shines in specific situations, showcasing incredible resilience.

  • Exceptional Durability: Crafted with superior materials and boasting an impressive IP68 waterproof rating, CIGS panels exhibit exceptional durability, capable of withstanding immense pressure and impacts. They demonstrate remarkable resilience even in the harshest environments.
  • Hailstorm Resilience: For areas in the United States prone to frequent hailstorms, typically those located in the so called "Hail Alley", such as Colorado, Kansas, Nebraska, Texas, and Oklahoma, investing in CIGS solar panels eliminates the risk of hail damage, saving a significant amount on potential replacements.

  • Peel-and-Stick Installation: Renogy 150W CIGS Solar Panel is designed with four adhesive strips on the back, providing a hassle-free installation process without the need for drilling holes in your RV's roof. This preserves the structural integrity while maintaining a sleek and clean aesthetic.

To begin installation, meticulously clean and dry the designated area. Once prepared, gently remove the adhesive tape from the panel's back and firmly attach it to the surface. Allowing the panel to remain undisturbed for a continuous 24-hour period is crucial, ensuring optimal adhesion and stability. This meticulous process guarantees a strong and durable installation, optimizing the panel's performance and longevity.

  • Lightweight Design: The lightweight design of CIGS solar panels is notably impressive, exemplified by their weight distribution. A 150W CIGS panel, weighing just 6.61 pounds, translates to an incredibly low 0.57 pounds per square foot (lb/ft2). This exceptional weight-to-power ratio makes CIGS panels an ideal choice for scenarios requiring high weight-bearing capacity per unit area. In settings like certain yacht canvas canopies and rooftop tents, where specific weight limitations per unit area are crucial, the CIGS solar panel stands out as one of the lightest options available.

  • Shading Efficiency: CIGS panels excel in shaded environments, outperforming C-Si panels with nearly double the efficiency. Their advanced technology allows for enhanced energy production when partially shaded by objects like trees, buildings, or debris.

Integrated bypass diodes are a crucial component of CIGS panels, adeptly mitigating the impact of shading. These diodes ensure uninterrupted power flow, safeguarding energy production even in shaded areas.

Furthermore, the interconnected cell design significantly enhances shading tolerance in CIGS panels. If a single cell gets shaded, the interconnected structure ensures the rest continue functioning, maintaining the panel's overall productivity.

Considering Drawbacks

However, it's important to take into account the considerations:

  • Space Requirement: CIGS panels demand a larger space due to their lower unit area load-bearing capacity. While they offer remarkable flexibility and unique advantages, accommodating their larger space requirement should be considered in the installation planning process.
  • Efficiency Gap: Comparing solar panel efficiencies reveals a substantial difference between CIGS and C-Si panels. While CIGS panels boast commendable efficiency levels, typically ranging between 15-16%, the noticeable efficiency gap becomes evident when compared to C-Si panels, which currently achieve efficiency levels of around 22.5%. This disparity could significantly influence decisions, especially for those prioritizing maximum efficiency in their solar energy setups.
  • Heat Absorption and Cost: The black design of CIGS panels, while aesthetically pleasing, has the potential downside of absorbing more heat, possibly impacting their efficiency. This higher heat absorption might lead to reduced overall energy output. Additionally, it's essential to consider that CIGS panels might have higher prices compared to some alternative options in the market. Understanding these factors in relation to specific project requirements and budget constraints is crucial when choosing the most suitable solar panel.
