Solar panels installed without Circut Breakers
Had four paneles installed, and I provided the equipment, they left out circuit breakers (2). I am bringing it back to installer, is this a big problem

On the panel side it is not necessary as the solar will self limit the current. You can short the panel and no harm is done. Switch is nice if service is needed.
On the battery side you should have a fuse as the full capability of the battery is in play. s/b within 18" of B+ and rated 125% of controller output rating and not higher than wire ampacity. Although if the wire is short, fully visible and low risk of damage maybe it can be skipped. But again very convenient to have a service switch to disconnect.
