Full custom solar power solution for lighting up the mailbox. This letter box is a practical choice for darker seasons as it can light up the mailbox cover for more convenient use. Solar solution covered a set of glass / backsheet solar module for which cut solar cells where used, a charger and a battery. Both charger and battery is hidden inside the top of the mailbox. We provided elegant, product design-fit black metal module frame to be used in this case. The placement and angle of solar module was chosen deliberately as the solar letterbox will be used in Scandinavian countries, where snow is a frequent guest.
We provided full solar solution – from custom solar module to personally picked junction box and provided option for integration.
All solar solution parts were tested in our in-house laboratory to maintain technical characteristics during long periods of harsh humidity and rain exposure.
Solar module and all the wiring were tested to meet requirements for longevity in most harsh weather conditions, and temperature peaks.
Cut cell solution enabled us to provide required power characteristics, while minimal gap size between cells allowed to reach maximum efficiency.
