JUST Small Modules 100-250W
Small-format mono modules 100W to 250W — off-grid, caravans, boats, signage, IoT, rural telecom
Small-format monocrystalline modules from 100W up to 250W, customisable to buyer spec. Built for off-grid and DC-load applications where standard 500W+ panels are oversized — rooftop caravans, river boats, telecom base stations, solar streetlights, rural water pumping, IoT sensor grids, solar-powered signage. All use the same JUST cell and lamination lines so quality matches our utility modules. Frame colour, cell count, dimensions, and junction box can be tuned per project.
