I have had a solar system for about 8 years and it's always worked perfectly well until a month or two ago. The electricity bill suddenly shot up and it turns out the reading on the inverter has shot up too. Around 3500 units produced by a 4kw system in winter. I'm assuming these two things are related but wondering if anyone has seen this problem before and can explain it?
The system is on a rental flat and the tenants recently left so I'm not ruling out foul play although can't imagine how....
