How do I know if my solar panel is bad?

Solar panel fault-finding guide including examples and how to inspect and troubleshoot poorly performing solar systems. Common issues include solar cells shaded by dirt, leaves or mould. Check all isolators are all on, and the circuit breakers have not tripped off. Check the grid voltage on the inverter display or app for over-voltage issues.

Why are warning labels and signs important to PV systems?

Maintenance and repair workers rely on up-to-date and accurate labels to ensure their safety and help them work efficiently. We’ve established that warning labels and signs are important to PV systems. Now, we can explain where they belong.

What are the advantages and disadvantages of solar PV power generation?

Most homeowners had no idea their PV system had a fault. Your electricity bill should tell you if your system's producing expected generation.

How do I know if my solar system has a fault?

Most homeowners had no idea their PV system had a fault. Your electricity bill should tell you if your system's producing expected generation. A large, unexplained increase in electricity costs could indicate a reduction in solar power. Also, comparing last years solar generation figures with this years will help spot if there's a problem.
