We have a complete line of pre-packaged solar lighting kits for off-grid cabins, sign lighting, underground shelters, and remote out-buildings. These are not based on those inexpensive solar walk lights being sold at a garden supply center. These solar lighting systems use only commercial quality components and are designed to light large areas for many hours each night. The size of the solar array and battery required will depend on the wattage and number of lights needed, and how many hours they operate. We use very high efficiency lighting fixtures that maximize the light output from energy saving compact fluorescent and LED type lamps.†
