How to Shield Your Solar Panels from Harsh Coastal Conditions.
If you live near the coast, you’ve probably wondered: Can solar panels really handle all that salty sea air? With the promise of lower energy bills and a more sustainable lifestyle, solar power is a no-brainer for many people here in Cornwall and the South West. But with the sea breeze comes salt, and that raises a good question—how well do solar panels stand up to coastal conditions?
The Short Answer: Yes—But with Conditions
Most modern solar panels are designed to be weather-resistant, including resistance to salt mist and corrosion. High-quality panels are rigorously tested under standards such as IEC 61701, which simulates the effects of salt mist on photovoltaic panels. If your panels are certified under this standard, they’re suitable for coastal installations.
However, even with this resistance, constant exposure to salty air and humidity can take a toll over time—particularly on mounting hardware, wiring, and inverter components, which may not always have the same level of protection.
Where Problems Can Arise
Corrosion of Metal Components: Mounts, frames, and connectors are vulnerable to salt-induced corrosion if not properly treated or maintained.
Reduced Efficiency Over Time: Build-up of salt residue on the panel surface can reduce sunlight absorption.
Damage to Electrical Components: Salt can infiltrate small openings and impact wiring or junction boxes, leading to performance issues or safety concerns.
Why Regular Maintenance Is Crucial
This is where Green Tech Solar Ltd comes in. As solar maintenance experts based in Cornwall, we serve customers throughout the South West, including Devon and Somerset. We know that a well-installed system is just the beginning. In coastal environments like ours, your panels face more aggressive conditions, and without routine maintenance, even high-quality systems can degrade faster than expected.
With regular checks and servicing, we help ensure:
Corrosion is detected early and addressed
Salt and grime are cleaned off panels to maintain peak efficiency
Seals, wiring, and connectors remain secure and safe
Your system’s performance is optimised year-round
