As someone who’s been in the solar industry for years, I’ve seen firsthand how a well-maintained solar system can deliver incredible performance—and how small issues, if ignored, can lead to big problems. At DH Electrical, we believe in empowering our clients with knowledge, so here are 5 key signs that your solar system might be due for a check-up.
1. ⚡ Your Energy Production Has Dropped
If you’ve noticed your electricity savings aren’t what they used to be, or your system isn’t producing as much power—even on sunny days—it’s a red flag. This could be due to dirty panels, shading, or even a malfunctioning inverter. Regular monitoring helps catch these dips early.
2. 🚨 Your Inverter Is Flashing Warnings
Your inverter is the brain of your solar system. If it’s showing error codes, flashing red lights, or making unusual sounds, don’t ignore it. These alerts are often the first sign that something’s not working as it should.
3. 🔋 Your Battery Isn’t Holding Charge
If your battery drains too quickly or doesn’t seem to charge fully, it could be a sign of aging batteries, poor connections, or a faulty charge controller. A healthy battery should comfortably carry you through load shedding and nighttime usage.
4. 🧼 Your Panels Are Dirty or Damaged
It might sound simple, but dirt, bird droppings, or even small cracks can drastically reduce your system’s efficiency. I always recommend a visual inspection every few months—especially after storms or dusty seasons.
5. 🔌 You Hear Strange Noises or Feel Excessive Heat
If your inverter or other components are unusually hot to the touch or making buzzing sounds, it could indicate electrical faults or internal wear. These issues should be addressed immediately to avoid further damage or safety risks.
Final Thoughts
Solar systems are built to last, but like any investment, they need a little TLC to keep performing at their best. At DH Electrical, we offer comprehensive maintenance checks to ensure your system stays efficient, safe, and reliable—year after year.
If you’re unsure about your system’s performance or just want peace of mind, give us a call. We’re here to help you stay powered, no matter what Eskom throws your way.
