The power produced by solar panels will depend on how much sunlight can get. The ideal output for this kit will be 500Wh every day(Calculated based on 100Wx5h expected sunlight availability).
7. Can I use this suitcase to charging my 120v receptacles directly?
The suitcase is not able to charging 120V power receptacles directly. Plus a 12v battery and inverter would give 120v output you would want. The panel would recharge the battery, the battery will storage the power, and the inverter would be able to supply the 120v power that you need.
8. Why is my solar panel underproducing?
Solar panel performance may be hindered for a number of reasons. Most commonly environmental conditions such as indirect sunlight, temperature rise, cloudy sky, and dirt and stain build up on the top glass will cause a reduced power output. This is a portable suitcase, you may try to move it in place or adjust the kickstands angels to get better sunshine. The ideal output of it will be around 500 Watt-hours per day (Calculated based on 100Wx5h expected sunlight availability).
