Speak with Loyal about repairing the broken solar array panels.
Repair the broken solar array panels.
If the player has at least 65 Repair they can proceed directly to the Nellis Array and fix each broken unit.
If the player has less than 65 Repair they must proceed to HELIOS One and retrieve the parts. HELIOS One is just north of Gibson Scrap Yard, which is just north of Novac. If you have not yet done the quest That Lucky Old Sun, an NCR Soldier will try to prevent you from entering. Use speech and convince them that you are a soldier or you can use a Stealth Boy to sneak past her (Sneak skill alone doesn't work). Go through the HELIOS One building until you get to the door that leads to the outside fences (if you entered through the main door, it's off to the left of the front desk. Going to the right leads to the doors that lead outside of the fenced in area you need to be in. Go straight past the stairs. The 5 parts are scattered around the perimeter fence, behind the NCR tents and next to the cage that houses a terminal. The parts look like fallen solar panels (you need a Repair skill of 20 to salvage the parts). Once you have all 5, head back to the Nellis Array and install them.
A Science skill of at least 50 will allow the player to upgrade the efficiency of the solar panels when he/she repairs them, netting 50 xp (55 xp when well-rested) instead of 30 xp (33 xp when well-rested) per each array repaired this way. If you have not restarted the generator the computer terminal is not powered, so make sure to complete that part of Ant Misbehavin' before you turn this in to Loyal if you want the extra xp. You cannot get the extra xp after Sunshine Boogie is completed.
Once all of the Solar Arrays are repaired, go back and speak to Loyal for 400 xp (500 xp if efficiency was upgraded) and fame with the Boomers.
Warning: Quest will remain active even if you have negative rep with the Boomers. Loyal will be hostile thus making the quest impossible to complete.
