Like all solar technology, SOLTECH’s solar lights require sun exposure to charge the lights’ batteries. This railroad car traveled their system and needed light inside to access tools and safely find and start the generator. The project’s main concern was exposing the solar panel to the sun while lighting the inside of the container. Luckily, the COSMO‘s design allowed the customer to mount the solar panels on the outside of the container and feed the cable to the light modules inside. The COSMO solar LED light has become the perfect solar solution for any shelter, canopy, or interior lighting application.
