Yeah, it's rough about Solaire... but you need to realize his power didn't come from his equipment. The running theory is that Solaire is actually the exiled son of Gwen that is mentioned on a few items, returning home. It explains his powers and his strength at any rate. Also, you should have picked up the Sunlight bug in there. You ever need to do Tomb of Giants, you can wear that on your head to light up the area like the light spell.
However, it IS possible to save Solaire by doing a certain sequence of events BEFORE fighting the Centipede boss in Lost Izalith.
- You need to join the Chaos Servant covenant located in the room directly beneath the Blighttown Bell. There is a false wall there you can hit to reveal Qualag's sick sister and her attendant Engi. Simple approach him, say you are a new servant, and then talk to her to join. Equip the Witch's Ring if you have it (you can get it by trading with the crow in the asylum or by picking it as your gift in a new game) to understand her speech, but it's not required.
- Joining up gives you Great Chaos Fireball. It's 3 uses, does excellent damage, and leaves a lava pool where it strikes for a bit. Also, if you've encountered a certain red phantom in 3 locations (Sewers, the path leading down into the demon area, and in Lost Izalith right before the boss) and defeated him all three times, there is a body here that gives you the Barbed Armor Set, which causes contact with you (such as via a roll) to cause damage. The story of WHY it's in this room is both sad and amazing.
- Now here's the hard part: leveling up in Chaos Servant requires you to use humanity items (or liquid humanity you get for helping other players with a boss) and then donate it to the sick drider girl. You need to give her -30- humanity. This takes you to +2 Chaos Servant, gives you Chaos Storm (a rocking pyromancy for PVP) and unlocks the shortcut to Lost Izalith.
- Now go through the demon area until you get to the area right before the fog door to the Demon Fire Sage. If you look to the right, there is an area full of thick roots. Climb down and open the shortcut.
- You are now in the area where you fought Solaire. Kill ALL OF THE BUGS (especially the red eye one) and be sure to pick up the Sunlight Bug. Since you got here before Solaire did, the Sunlight Bug won't drive him crazy.
- Finish Lost Izalith.
- You'll see Solaire one more time now. He's a bit distraught since he cannot find a sun... but he promises to help you again if you need it.
So why would anyone go through all of that (other than to save our Sunbro)? This unlocks Solaire's sign in the Kiln of the First Flame, enabling him to help you with the final boss. 30 humanity to skip two simple bosses, a crappy area, and to get a summon isn't a great deal, but it's there if you want it.

So what do you have left? You did Lost Izalith, New Londo, and Duke's Archives. Did you do Tomb of the Giants and Nito yet? If you have, then all that's left are the DLC areas and the Kiln of the First Flame.
