Humming Noise After Installing The Solar Panel

A slight hum is normal.

Humming noise after installing the solar panel.

Then disconnect the panels one by one. I had the sma sunny boy 2100tl installed with 8 trina honey panels. What solar panel you are using. Solar panels are becoming much more common in australia and around the world.

Consider that even if installed near a bedroom window the inverter switches off during the night. Electrical interference is a problem that might be encountered with solar power system electronics. But this past summer the installation of a new municipal solar array added a new sound to the mix. However as soon as it was working under load the next day my computer psu started to make some very loud high frequency noise.

As soon as the solar project went live inverters the part of the system that converts direct current from the sun to alternating current began emitting. One common question asked is whether solar systems make noise. You most likely don t need to do anything. Look at the product datasheet for noise data.

Solar system inverter noise. If you re talking about a residential solar pv system noise emission data is readily available on inverter spec sheets but generally speaking they re not particularly noisy. So i ve just had my solar system installed by solargain who have been pretty great to deal with so far. This may cause wind noise.

Disconnect the dc side of the pv system from the inverter and try to listen to the noise. Perhaps you should climb up to your roof and try to listen to the humming noise. Noise emissions from inverters are generally reduced by a combination of shielding noise cancellation filtering and noise suppression. Incessant humming that all but drowns out the other sounds at some smith hollow residences.

I had seen something like this possibly one or more of your panel junction box is making that noise. Just so you know the solar panels are not directly attached to the roof itself but to racking that is attached to the roof. Breakers often produce a humming noise from the vibration of the electrical currents. Sma s popular sunny boy inverters for example are about 25db quieter than a refrigerator producing more of a hum.

Luckily for you it s most likely not a problem. As with all new technology people may make assumptions or have questions about how the systems work and what the impact is on their homes and local neighbourhood. Nevertheless for shift workers etc the lesson is buy a quality inverter and try to install the inverter near the switchboard and not direct outside the bedroom window. But depending on how they were installed airways can be created underneath the solar panels or between the solar panels and the shape of your roof.
