The Hidden Risk in Farm-Based Solar: Ammonia Corrosion
As agriculture embraces clean energy, solar power is becoming a staple on farms, powering everything from irrigation systems to full-scale agrivoltaics. But there’s a silent threat that many overlook when installing solar panels near livestock or crops: ammonia corrosion.
Ammonia (NH₃), a byproduct of animal waste and fertilizers, can severely degrade solar panels if not properly addressed. Over time, it eats away at key components of PV modules, leading to performance drops and costly replacements.
What Is Ammonia and Where Does It Come From?
Ammonia is a pungent, colorless gas produced from:
- Livestock waste (e.g., poultry, pigs, cattle)
- Fertilizer use in greenhouses and fields
- Manure storage areas
- Poorly ventilated barns or confined animal spaces
In enclosed or semi-enclosed agricultural buildings, ammonia levels can rise significantly — especially dangerous for sensitive solar panel components.
How Ammonia Damages Solar Panels
Without proper protection, ammonia can cause:
- Backsheet cracking – compromising weather resistance and electrical safety
- Encapsulant yellowing – reducing sunlight transmission
- Corrosion of metal frames, junction boxes, and solder points
- Sealant breakdown – allowing moisture to enter and cause short-circuits
📉 Studies show panels exposed to high ammonia can lose 10–15% of output in just a few years.
The Solution: IEC 62716 Certified Panels
The global solar industry recognizes this issue — and addresses it with IEC 62716, the ammonia resistance standard for PV modules.
To pass this test, panels must withstand prolonged ammonia exposure under simulated farm conditions without showing electrical or mechanical failure.
💡 Tip: Always check if your solar panels are IEC 62716 certified, especially if you’re installing near livestock, fertilizer use, or manure zones.
Real-World Cases: What Happens Without Ammonia Protection?
- 🚨 A poultry farm in Spain saw significant power loss in 2 years due to backsheet damage.
- ✅ A French agrivoltaic site using IEC 62716-certified panels maintained >95% output after 5 years.
- ⚠️ A pig farm in the U.S. had to replace 20% of its panels early due to yellowing and delamination.

How to Protect Your Solar Investment on Farms
Here are 5 essential tips to safeguard your PV systems in agricultural settings:
- ✅ Use only IEC 62716 certified solar modules
- 💨 Ensure good barn or greenhouse ventilation
- 🧪 Opt for panels with ammonia-resistant backsheets and sealants
- 🔍 Conduct regular inspections for cracks, discoloration, or power dips
- 🛠️ Work with experts like EcoSync who understand agricultural solar
Conclusion: Ammonia Resistance Is Not Optional
Ammonia corrosion is a silent but serious risk for any solar project near agriculture. Without protection, systems degrade faster, underperform, and cost more in the long run.
With IEC 62716 certified panels from EcoSync, you get a solution built to endure — keeping your energy yields high and your farm operations sustainable.
