Most shoppers assume that solar panels feed directly into the light source.
This simplistic view works for the science experiment in class, but in a commercial application, a more robust system is needed.
Most modern solar systems use a battery system for storing electricity until it is needed. As it turns out, these charging systems and batteries are every bit as important as the solar panels.
An efficient charge controller will optimize the rate of charging to ensure that as much energy is fed into the battery system as is safely possible, based on the weather and solar conditions of that day
Then, at night, these charge controllers are responsible for using the energy in an efficient manner and providing light.
Solar Lighting International specializes in patent-pending charge controller technology that wastes the least amount of energy possible while still offering the longest battery life. You can read more about this solar street light system, here: https://www.solarlightingitl.com/
An efficient lighting system will use a high-end charge controller, a reliable battery and a low-amperage LED system that still delivers an optimal amount of lumens.
When spec’d appropriately, even small municipalities can afford solar lighting systems. These solar lamps then provide lighting for rural communities with no need to trench for electric lines and no monthly electricity costs.
