Hello,
I am building Solar Guitar™ prototype, an eco-friendly, self-sustained musical instrument solely powered by the Sun:
https://patents.google.com/patent/US9905213B2/en
10-15 watt, 2 speaker stereo guitar amplifier with reverb/chorus/delay/overdrive will be installed into the guitar’s body.
I am looking for a creative specialist to build it. As a reference please view the following link:

Your comments and suggestions will be greatly appreciated.
Best regards,
Aleks

Here's your power-source:

6x10" 3A (15W) @ 5V solar panel- that's max. As your speakers are magnets, your real problem is dynamic response for the magnetics- which may spike in their need for current depending on response.... likely big caps necessary. I imagine the solar-panel shown in the link is 15W _best case/brightest sun_. Mileage may vary. Good luck.

It's not good to leave your instruments out in the sun. Temperature and humidity wreaks havoc on instruments and their ability to stay in tune... it could have lasting effects. Maybe you can have the solar panels elsewhere... on the amp?

It doesn't have to be in the direct sun, just in the comfortable shade. Plus another 12 volt solar panel is on the guitars case, so the guitar could be charged on the move.

Thanks! I'm thinking of using 9 watt, 12 volt durable solar panel:https://voltaicsystems.com/9-watt-18v-panel/
The best I could find.
