Compare a 15 W monocrystalline solar panel offered alone or with a charge controller. The listed panel measures 380 × 280 × 3 mm, with 18 V working output and 21.6 V open-circuit voltage. Both packing lists include a photovoltaic connector; only the controller kit lists a controller. Confirm battery chemistry and electrical limits before connecting a nominal 12 V battery. Generic dual-USB and flexible-mounting claims need actual component specifications.
