I work for an outdoors company and we are setting up a shed to be used for an office. There is no power at the shed site, so we'll be installing an 1800 watt Solar Panel system. I am having trouble finding lighting for the inside of the shed. It's easy to find outdoor patio lighting, but not indoor lighting. Would it be better to simply plug lamps into the inverter? Or are there lights that have their own solar panels that are powerful enough to light up the inside of a shipping container?
