If you’ve got solar panels on your roof, you probably check your energy bills now and then. But how often do you check what your system is actually producing? That’s where this solar generation meter guide comes in. Most homes with PV setups have one—it’s usually a little display mounted near your fuse box or inverter, quietly tracking how much electricity your panels are generating. This guide shows you how to read that meter, spot signs of underperformance, and understand what’s normal for your area and system size.
