Fallout: New Vegas/Sunshine Boogie
Sunshine Boogie is a quest for the Boomers. Loyal states that the solar panels are damaged and need to be repaired.
If you have at least 65 points in the Repair skill, you can fix the panels directly. Otherwise, you need to head to Helios One and retrieve all panels that are marked on the map. To access Helios One without engaging the NCR, you must have Accepted reputation (or better), or have sufficient speech or science. However, Helios One has a side door that may be picked.
Once the equipment is repaired, speak with Loyal to complete the quest.
