India is a promising market for solar energy due to its abundant sunlight. But a common question among potential users is: Are solar panels efficient in cloudy and dusty environments? The answer is yes, but with a few crucial considerations. Here is a look at how solar panels perform under such conditions and how they can be optimized to maximize their efficiency.
Solar Panels on Cloudy Days: Do They Still Generate Power?
It is true that solar panels generate electricity even when it is cloudy
Days. Although sunlight intensity is reduced due to cloud cover,
Modern solar PV systems are designed to capture diffused sunlight—the
Sunlight that is scattered in the atmosphere even when the sun isn’t directly
Visible.
On a cloudy day, solar panels typically operate at 10% to 25% of their
Capacity,Capacity, depending on the thickness of the clouds.In regions like Kerala, which experience monsoons and overcast days, high-quality solar panels with advanced cell technology (like PERC, bi-facial, or
Half-cutting can still ensure a decent output.
Impact of dust on solar panel efficiency
Dust accumulation is more common in dry and arid regions like Rajasthan, Gujarat, and parts of Maharashtra. Even in cities, pollution and construction activities contribute to dusty conditions.
Layers of dust can reduce solar efficiency by 5% to 15%, and in
Severe cases, up to 30%.The loss is gradual and often goes unnoticed until production starts dropping
Significantly.
Solutions and Tips to Overcome Cloudy and Dusty
Challenges
1. Choose High-Efficiency Panels
Bifacial and monocrystalline panels work best in diffused light.
Panels with an anti-soiling coating help reduce dust buildup.
2. Tilt Angle and Installation Design
The correct tilt helps natural rainwater clean off dust.
A customized structure ensures maximum exposure during different seasons.
3. Regular cleaning and maintenance
Monthly cleaning in dusty areas is a must.
Bodhie Solar provides Annual Maintenance Contracts (AMC) with scheduled
Visits and performance tracking.
4. Remote monitoring systems.
Identify drops in performance instantly using real-time monitoring apps.
5. Location-Based Planning
Systems : In coastal or humid areas, they are designed to tackle corrosion and salt mist.
Dust-prone Systems : Are equipped with high-rated IP junction boxes and
Cleaning accessible.
