Not seeing savings? Let’s talk about how to know if your solar panels are working, because a non-performing system means lost money every single day.
So, you’ve installed solar panels, but your energy bills still seem high and now you’re wondering:
Is my solar system actually working?
Whether your feed-in credits look low or your inverter is flashing red, it can be tricky to tell what’s normal and what’s a warning sign. In this guide, we’ll walk you through how to check your solar panel performance and spot when something’s not right, before you lose more money.
1. Check the Tech: Inverter & Monitoring
Your solar inverter is the easiest place to start.
- Green light? You’re good.
- Red or flashing lights? Something’s wrong.
If your inverter has a screen or an app, it should show your live generation. On sunny days, you should see consistent output. Flat lines or no data? That’s a red flag.
No app or monitoring setup at all? That’s a bigger one – especially if your installer never mentioned it.
2. Look at Your Power Bill
Your electricity bill is a quick reality check. After installing solar, you should see:
- Lower daytime usage charges
- Feed-in credits (for excess power you export)
- A clear drop in your total spend
If none of that’s happening — especially in summer — your system might not be working at all. And if your usage pattern hasn’t changed, it could also be a sign of poor installation or configuration.
3. Don’t Blame the Weather – Get It Checked
Sure, solar output drops in cloudy weather — but not that much. Even in winter, a working system should still offset part of your usage.
If you’re constantly wondering whether your panels are working, it’s time for a system check.
