How Sungold Anti-hotspot Solar Panels Can Help
Hot spots can lead to substantial power loss, module damage, and even early system failure in conventional solar systems. Sungold’s cutting-edge technology solves this problem with precision, allowing for optimal module performance across a variety of conditions.
Cell-level shadow management technology
The Sungold Anti-shading technology continues to generate power in partial shading where traditional panels stop working altogether.
Reduced Hotspots
In conventional panels, debris or shading can cause hot and cool spots which lead to micro-cracks within the cell, this new design minimizes this problem and contributes to a longer lifespan.
Environmental Durability
Using advanced materials this panel can handle snow, rain, and even small hail for decades (aka, ≥IP67 protection). The sturdy 1.2mm aluminum frame provides enhanced impact resistance.

Outstanding performance even in the shade
We carefully manage hotspot batteries to reduce the number of batteries affected by hotspots and ensure consistent performance is delivered throughout the day.
No more worrying about shadows
Performs well in changing sunlight angles and provides consistent power output to ensure you get value for your investment.
Enhanced hot-spot resistance
By embedding components inside the module, Sungold carefully manages hotspot cells and reduces the number affected by hotspots. At the same time, our innovative process technology ensures that the module stack diode temperature remains below 85°C during peak current output, increasing module output and safety.
The Ideal Solution for Shading in Any Scenario
The anti-shading solar panels are engineered to perform exceptionally well under varying sunlight angles, ensuring consistent power generation throughout the day. Unlike conventional panels that can suffer from partial shading or low-angle sunlight, these panels maintain high efficiency even when the sun’s position changes or when partial shading occurs from trees, buildings, or other obstructions.
Solar Tracking Systems
Tracking systems adjust the position of the solar panels throughout the day to follow the path of the sun, maximising exposure to direct sunlight and minimising the incidence of shadows.
Although they represent a more significant initial investment, they can offer a considerable increase in energy production.
Adaptive Technologies for Shaded Roofs
Solar panels designed for shaded roofs use specialised technologies, such as split solar cells or energy optimising modules, which generate electricity even in sub-optimal conditions.
These systems are ideal for installations in urban areas where shadows are unavoidable.

Frequently Asked Questions about shading in solar panels
Thank you for your interest in our flexible solar panels. Here are some frequently asked questions that may be of interest to you:
What happens to solar panels when they are partially shaded?
When a solar panel is partially shaded, the shaded cells generate less current, which can reduce the output of the entire string. Unshaded cells continue to produce electricity, but the current may be blocked or redirected, causing power loss and even hot spots. Without protection like bypass diodes, shading can seriously degrade performance.
Can solar panels still work efficiently in shaded areas?
Standard solar panels lose efficiency under shade. However, anti-shading solar panels with bypass diodes or cell-level shadow management technology can reroute current around shaded cells. This allows the rest of the panel to continue producing power efficiently, making them suitable for partially shaded environments like rooftops or RVs.
What are anti-shading solar panels and how do they work?
Anti-shading solar panels are specially designed to reduce energy loss caused by shading. They use bypass diodes or advanced circuit design to redirect current away from shaded cells, preventing overheating and maintaining output. Technologies like Sungold’s 863 offer cell-level shadow management for even better protection.
What is cell-level shadow management in solar panels?
Cell-level shadow management refers to dividing a solar panel into smaller segments, each with its own bypass path. This design ensures only the shaded area is bypassed, while the rest remains active. It enhances shading tolerance and is key to high-efficiency anti-shading panels like those using Sungold’s 863 technology.
How can I avoid hot spots caused by shading on solar panels?
To avoid hot spots, use solar panels with integrated bypass diodes or anti-shading technology. These systems automatically reroute current when shading occurs, preventing overheating. Proper installation, regular cleaning, and choosing high-quality, shade-tolerant panels are essential to protect against thermal damage.
Are shade-tolerant solar panels worth the investment?
Yes. In areas with trees, chimneys, or nearby buildings, shade-tolerant solar panels offer better long-term energy yield. While slightly more expensive, they reduce performance losses, prevent damage, and lower maintenance costs—leading to a higher return on investment over time.
Which solar panels perform best under partial shading?
Panels with advanced anti-shading features, such as cell-level bypass architecture, perform best under partial shading. Brands like Sungold offer panels with 863 circuit design, enabling better energy retention and thermal protection. Look for “shade-tolerant” or “anti-shading” in product specs.
Do bypass diodes prevent shading losses in solar panels?
Yes. Bypass diodes allow current to flow around shaded or faulty cells instead of through them. This avoids voltage drops and hot spots. While traditional diodes cover larger cell groups, modern panels like Sungold’s use more refined zones for faster, localized response and reduced shading loss.
