How Feston’s Rooftop Solar Systems Stay Resilient During Monsoons and Heatwaves
Engineered for India’s Real-World Weather
In India, the weather isn’t just a backdrop — it’s a challenge.
From blistering 45°C summers to week-long monsoon rains, your solar system needs more than just sunshine — it needs stamina. At Feston, we’ve built every product with India’s climate in mind, because reliability isn’t a feature — it’s a necessity.
Let’s take a closer look at how Feston’s rooftop solar solutions stay resilient, safe, and smart — rain or shine.
🌦️ Weather in India Isn’t Friendly to Electronics
If you’ve lived through a Tamil Nadu thunderstorm or a Delhi heatwave, you know the elements can be brutal. For solar systems, this means:
- Water ingress during heavy rains
- Voltage surges from lightning
- Overheating during peak summer
- Dust build-up on panels and connections
While panels on their own are weatherproof, the real test lies in the components you don’t see every day — the inverter, ACDB/DCDB, cables, isolators, and mounts.
🔐 Built for Monsoon: How Feston Handles the Rains
- IP-Rated Enclosures (IP65 and above):
Feston inverters and junction boxes are sealed against dust and water spray. That means you don’t have to panic every time it rains.
“Even during the October downpour in Kerala, the system never shut down. We’ve had no leakage or inverter fault.”
– Rajesh P., Installer in Kochi
- Weatherproof Mounting Structures:
Our rooftop mounts use rust-resistant galvanized steel, designed to withstand high humidity and coastal corrosion. - Proper Water Drainage Planning:
We guide installers to leave drainage gaps and maintain panel tilt — no water pooling, no hotspots.
🔥 Beating the Heat: Solar That Doesn’t Sweat
- Thermal-Resistant Inverter Design:
Feston inverters are tested for high ambient temperatures. With built-in cooling fans and heat-sinking enclosures, they keep operating smoothly — even when your rooftop feels like a tandoor. - Over-Temperature Protection:
The inverter auto-adjusts load and gives you alerts if it ever gets too hot — thanks to smart firmware logic. - Low-Voltage Battery Compatibility:
Our LiFePO₄ batteries are ideal for India’s thermal range, with built-in BMS to handle charge-discharge safely, even during power-hungry summers.
⚡ Lightning & Surge? No Worries.
With monsoon comes lightning — and with it, power surges that can damage equipment. That’s why Feston systems include:
- Surge Protection Devices (SPDs) inside ACDB/DCDB
- Proper Earthing Guidance as per IS 3043
- DC Isolators placed close to panels — to cut risk during faults
“In a lightning-prone area like Nagpur, the ACDB box design saved us during a surge. The MCB tripped, but the system stayed intact.”
– Deepak T., EPC contractor
