Using Solar panels for energy conversion?

AI Thread Summary
The discussion focuses on using solar panels to power Bluetooth noise-cancellation headphones, emphasizing the need for clarity on power consumption and voltage requirements. Participants suggest starting with specific power consumption data to determine the appropriate solar panel size and type. Simple photovoltaic cells that produce USB 5V outputs are recommended for their compatibility with charging devices. Understanding how these panels convert variable output voltage into a stable supply is crucial for the project. Overall, the conversation highlights the importance of matching solar panel specifications to the headphones' energy needs.

Hi guys I am working on a project in which i use solar panels to drive a pair of headphones

my main question is what kind of solar panels would you guys recommend? that could help with this kind of project

The question is way too vague for a specific answer. What do the headphones do? Just powering them without some source of sound would be quite pointless.

their basic bluetooth/noise cancellation headphones, the project is to use solar energy as an alternative to charging/powering up the battery without the need for an electrical outlet

So start with your power consumption numbers. What voltage do they require? What power do they consume?

Then look at simple photovoltaic cells, and see how big it will have to be to produce that power in whatever sunlight conditions you expect. I'm guessing you can find some existing panels that produce USB 5V outputs of a few watts in reasonable sunlight conditions. Start by checking them out, and understanding how they convert the variable output voltage of PV cells (for different light levels) into a constant voltage for powering the loads... :smile:
 
I use something like this to recharge my phone and my ipad. If your headphones charge with USB, this might work.

Hi all I have some confusion about piezoelectrical sensors combination. If i have three acoustic piezoelectrical sensors (with same receive sensitivity in dB ref V/1uPa) placed at specific distance, these sensors receive acoustic signal from a sound source placed at far field distance (Plane Wave) and from broadside. I receive output of these sensors through individual preamplifiers, add them through hardware like summer circuit adder or in software after digitization and in this way got an...
I have recently moved into a new (rather ancient) house and had a few trips of my Residual Current breaker. I dug out my old Socket tester which tell me the three pins are correct. But then the Red warning light tells me my socket(s) fail the loop test. I never had this before but my last house had an overhead supply with no Earth from the company. The tester said "get this checked" and the man said the (high but not ridiculous) earth resistance was acceptable. I stuck a new copper earth...
I am not an electrical engineering student, but a lowly apprentice electrician. I learn both on the job and also take classes for my apprenticeship. I recently wired my first transformer and I understand that the neutral and ground are bonded together in the transformer or in the service. What I don't understand is, if the neutral is a current carrying conductor, which is then bonded to the ground conductor, why does current only flow back to its source and not on the ground path...
