Solar Illuminations offers a large selection of commercial solar lighting systems. Most of the products we offer are commercial grade kits that are designed specifically for your requirements. One-size-fits-all solar lights can be a useful option for some applications, but if you want a solar light that performs reliably year-round, rain or shine, then you’ll want a heavy duty commercial option. When you purchase a system from us, if you desire dusk to dawn illumination, that means dusk to dawn. We’ll determine the longest night of the year (which can be up to 16 hours) and the weather conditions in your location. We pick the worst case scenario and base your system around it, along with providing additional battery back-up.
