Two Goal Zero Boulder 15 Ver 2 15 watt solar panels with carry case. Chain multiple together or use separately. Connects directly to Sherpa 50, Yeti 150, Yeti 400 Power Pack. Has a built-in USB port to charge small devices directly from the solar panel.
The Boulder 15 (Version 2 with USB ports) is a solar panel with versatility. Because of its strong tempered glass and the aluminum frame, it can be installed, but it's light enough to take with you in the carry case provided with the kit. Great for RV, cabin, camping, and trickle charging.
NOTE: These solar panels are designed to connect to other Goal Zero products like the Yeti 150, Yeti 400, and Yeti 1250.
Two Boulder 15 solar panels come with this kit giving you a total of 30 watts of charging power. The nice thing about Boulder 15 Solar Panels is that each of them has their own USB port and chaining cable. This allows you to use each panel individually to charge a USB device or you can chain them together for double the charging power.
Two Goal Zero Quick Clips are included with the kit. These clips are used to attach the panels together. Under certain conditions it may be easier to position both panels attached together. The solar panels have holes on all sides for quick clips.
Powerful Products has designed a carry case specifically for the Goal Zero Boulder 15 solar panel. This rugged case safely carries two solar panels. A huge side pocket allows you to carry other cords, cables, devices etc.

I bought 3 kits which will yield 90 watts. This will be teemed with a charge controller connected to a 100 amp hour gelcell battery. This combination will give about 60 amp hours (or more) charge when the photo voltaic cells are exposed to the sun for eight hous.
The cells can be assembled into a single unit using the clips provided. I did have a problem with the clips not fitting in the slots in the aluminum frame. It was nessary to enlarge the slots slightly to allow the clips to pass trough them.
When not in use, the cells can be stored in their heavy duty case and stored or transported. The cells are well made and have a socket on their backs so that they can be connected in parallel. Be sure to get an extension cable when you order the cells so that you can connect them to whatever you want to power especially if you are not using Goal Zero products.
If you want to do your thing and buy your own components, the rule for charging a battery is to have at least two amps of charging current per 100 amp hours if battery capacity. Of course, the higher the charge rate the faster the battery will be charged.
