4 Frequently Asked Questions about "Reasons for excessively high voltage on photovoltaic panels"

What causes a high voltage in a multi-phase solar system?

When grid voltage is already high, even a small additional rise from solar generation can push the total voltage above acceptable limits. In multi-phase systems, unbalanced loads across different phases can contribute to voltage rise. This is particularly relevant when single-phase solar systems are added to multi-phase electrical installations.

Does solar analytics detect over-voltage issues?

Depending on how long the system is turned off due to the over-voltage issue, Solar Analytics will detect it either as a zero production fault or an under performance issue. In both cases, we will notify you depending on its severity. Some examples of over voltage issues will look like on your dashboard can be seen below.

Why is voltage drop important for solar panels?

Addressing voltage drop issues can maximise the efficiency and performance of your solar power system, ensuring optimal energy production and longevity of the installation.
