Note: You've achieved the technical ability for the construction of the system. In the future, I would like to see the wiring tidied up please. And a quick point aboit your calculation, multiplying by 60 and then divig by 3600 converted minutes to seconds to hours, (90*25)/60 would have been sufficient.
Discussion is ongoing behind the scenes about this BB submission... Unapproving it for the moment...
Someone flagged this submission as an edge case BB.
BBV price: 0
Note: Sorry. A 100 watt bulb requires 8.333 amps at 12 volts. 8.333 x 6 hours = almost exactly 50 amp hours. It appears your battery is a little too small to meet this posted requirement "Explain how the battery(s) will put out 100W for 6 hours." Using an inverter would introduce losses that would increase the overall power needs even more.

BBV price: 1
Note: Please include a picture of the 12 volt outlet. It appears that the phone is charging from a different USB outlet than the one built into the controller. The panel needs to be fully installed for this BB so include a picture if it mounted on the platform.

Note: Allowing a little leeway due to the long delay. The required pix are shown in the links.

BBV price: 1
Note: You can't not use the same work for two BBs in the same Badge. You got the points for installing the DC outlet, the requirement for the DC outlet in this badge needs to be another outlet.

To complete this BB, the minimum requirements are:
o choose one of the following systems to build:
- small solar music cart and phone charging station
o includes 12v bluetooth speakers hard wired
o must have at least one 12v outlet
o must have at least one 5v USB outlet
o must include a charge controller
o must include a battery
- must be able to put out 100 watts for 6 hours.
Provide photos or video (< 2 minutes) of the following:
- Description of the system, power and capacity. Explain how the battery(s) will put out 100W for 6 hours
- Area where the system will be installed
- Parts before you install/assemble them
- Completed installation
- Evidence of a phone charging
Side Notes:
If you have an alternative solar installation that you'd like to do of a similar complexity, post below and ask if it could be added as an option.

I love that Rocket Mass Heaters are Carbon-Nuetral. In Erica's and Ernies Art of Fire Presentation, Erica explains the chemistry of how that's possible!
I attended Helen's Garden Master Course in January 2022 and give the lectures 10/10 acorns! Fortunately for you, you can also see the Garden Master recordings but unfortunately you'll miss out on the fruit Helen grew and shared. It was the tastiest fruit I've ever had!
