Studies show that hotspots are one of the biggest culprits when it comes to low solar panel efficiency.
These hotspots can not only bring down your overall generation but also damage the panels in the long run!
While there are multiple causes of this problem, the top one is shading, especially at the corner of the panels.
In this blog, we will break down the science of hotspots on the panel edges and understand how you can avoid them with a simple solution.
Hotspots on the Solar Panel Edges
Hotspots occur when there is some sort of obstruction in the flow of current in a solar cell. Instead of doing their job of generating energy, these weak cells start leeching power from their neighbors, throwing off the whole energy-producing groove.
Consequently, the generation of the entire string goes down.
An often overlooked cause of these hotspots is shading, primarily due to dust accumulation on the panels. Research indicates that the presence of dust leads to partial shading, resulting in hotspot heating.
Now, you might think, “Just keep those solar panels clean, problem solved!” And you will be right to an extent.
However, there are some cases where you’ll find that though the panels are clean, the edges of the modules remain dirty.
This is because, after cleaning sessions or during rainy seasons, the water tends to collect at the corners of the panels due to their tilted placement. As the water evaporates, it leaves behind a layer of dust that gradually thickens over time.
While robotic or manual cleaning can mitigate this residue to a large extent, the presence of even a few millimeters of residual water and a thin layer of dust can be detrimental.
If you don’t address this promptly, the minor concern can lead to a loss in generation. This, almost insignificant generational loss in a single module, can add up in MW-scale plants. Moreover, this small issue can reduce efficiency, give rise to hotspot effect, and create a potential for burn damage on the solar panel.
But, there is no need to worry. You can avoid the whole problem with just one solution- Aqua Pi.
What is Aqua Pi?
Aqua Pi is a tiny but incredibly powerful water drainage clamp that gets attached to the lower edges of the panel. This made-in-India solution removes the excess water from the modules using the principle of surface tension.
In doing so, Aqua Pi checks the accumulation of dust and dirt on panel edges and prevents the formation of hotspots. Further, the device prevents damage to insulation due to the buildup of moisture and boosts solar generation by up to 10%.
The patented solution is made of high-quality thermoplastic Acrylonitrile Butadiene Styrene and can withstand all weather conditions.
The material is corrosion-proof and has a lifespan of over 25 years. This means, that this one solution can avoid shading at the panel edges and raise efficiency for the entire life of the solar power system.
Advantages of Aqua Pi:
- Enhances panel output by up to 10%, maximizing energy generation.
- Safeguards against dust buildup and inhibits hotspot development along panel edges.
- Corrosion-proof and suitable for all weather conditions.
- A one-time investment that lasts for the entire life of the system
- Cost-effective solution with an aqua pi cost accounting for less than 1% of the price of the panel.
How to Use Aqua Pi?
Every panel requires just two of these clamps. The devices are attached at the lower edges of the panels, at a distance of 10mm from the corner.
There is no need for professional expertise when it comes to installing Aqua Pi. Anybody can snap-fit the clamp manually to the edge of the solar panel.
Once fitted, any collected water will be drained automatically
Frequently Asked Questions
• How does the Aqua Pi prevent shading issues on solar panels?
Aqua Pi drains collected water from the lower edges of the panels and prevents dust accumulation which can act as a shadow on a panel.
• Is the clamp compatible with different types of solar panels?
It seamlessly fits panels with a standard thickness of 35mm, which is commonly found in the majority of solar panels available in the market.
• Can it withstand extreme weather temperatures and other environmental factors?
Certainly. Aqua Pi has undergone rigorous testing to ensure its resilience. Additionally, it is constructed with high-quality ABS material known for its resistance to extreme temperatures, both hot and cold.
• Are there any maintenance requirements for the Aqua Pi?
Aqua Pi does not require regular maintenance. In case you observe a decrease in water drainage efficiency, a quick inspection to clear any accumulated dirt inside the clip is all that is needed.
• Can the Aqua Pi be used in solar installations with tracking systems?
Yes.
• Is there a support system in place for addressing any issues or queries post-purchase?
Absolutely. Ornate Solar has a dedicated in-house technical team ready to assist you with any issues that may arise post-purchase.
