We had a new PV system installed. Now we can hear cracking noises in the attic very frequently, sometimes every minute. Is this normal?

Which flashlight THW?
Good morning, I think I have this in our OV Flashlight flying around seen: https://www.led-martin.de/nightstick-helmlampe-inkl.-haltersatz-atex-xpp-5418gx-k01.html What puzzles me is the Legendlich 200 lumens. Since dive lights often have around 11,000 lumens, and this one has just a fraction of that, that seems rather odd to me. Now I'm wondering if this is a typo, if…
Power bank not used for 2.5 years?
Does anyone have experience using an old power bank (Anker) when it hasn't been charged for over 2 years? Is it possible to recharge it or is it better to dispose of it?
How do you measure cable thickness?
Hello, how do I measure the circumference of cables that are only a few millimeters thick, or generally? Thank you for your answer.
Inverting operational amplifier?
Bysuppe1
Hello dear community, I am stuck on the following task: The sensor signal from the inverting op-amp is to be converted to analog-to-digital converter (ADC). What is the minimum input resistance of the AD converter so that the voltage is not distorted by more than 0.5 microV? The maximum voltage at the input of the…
AC brushed motors performance difference?
Hello I recently wondered what the difference is between these two motors with almost the same power consumption (around 350W). They differ significantly in size, the smaller one comes from a hand mixer, the larger one is a washing machine motor. What doesn't seem convincing to me is that the washing machine motor is much…
Does anyone know anything about the power supply of LED strips?
ByKlipe
Hello, I'd like to use an LED strip with a controller, but I'm a bit unsure whether the power is sufficient to make all the LEDs glow evenly. I've included images below showing the voltage and wattage specifications. I've already found the controller for the LED strip, but I need help finding the power supply….
These are probably voltage cracking because the PV system expands and contracts.
Thanks for the star.
Let me guess it’s cracking around the more the more the sun’s on it?
Then you have forgotten to move the panels at a distance and “floating”!
Thank you very much for the answer! I don’t know. It’s cracking at night. We let it be done by a recognized company, there was also a Statiker. How do you know if it was laid floating and is it bad if not, can something happen?
Possibly tap because the parts were mounted too tightly more quickly.
Normal is never that.
Thanks for all the answers! We haven’t asked yet. And if the company itself is the best contact person, I don’t know, I have self-interest. What I wanted to add:the plant is not yet in operation
Hello,
I fear that the roof load has not been taken into account.
