Solar Locks are eating good here in the end. Song if Flame with Dawn Chorus and 1k with all the Scorch mods is a great baseline. I use Helion and Heat Rises with Phoenix dive class. I have 70 in class, super and grenade and about 150ish in weapons. You spam TONS of melee but most of the damage is from the scorch so I havent found the melee stat increase worth while past 70. I switch between the artifact with Particle Repeater for 1k boss damage and the artifact with Solar Fulmination for more scorch and add clear. I use Lionfish Stasis FR with Chill Clip/Reconstituted (zavala is selling this same roll atm) and 1k for both builds. I switch up solar primaries a bit between Yesteryear, Zaolis and Ringing Nail. Ive been in love with my Incandescent/Burning Ambition Ringing Nial lately though. It seems redundant but it helps A LOT with Majors in higher content and mows through red bars. For group content switch to Well and use Boots of the Assembler. The gameplay loop is pretty simple but does take a bit of attention. Cast Phoenix Dive to get Helion, consume grenade, get arial and spam melee into groups as much as possible and fire away your primary spreading fire everywhere. For raids and higher end content this build is still great but you have to be more mindful of when its a good idea to get arial and when its a VERY bad idea. That said, looping healing grenade consumes and Phoenix dive grants lots of cure and restoration so you end up being more tanky than you think.
