The solar Lighting is again a photovoltaic (PV) module that collects energy from the sun and stores it in batteries to operate the required wattage of light at night. This is generally used for energy savings, cost
savings, and environmental reasons. These systems are called grid free or stand-alone meaning that they generate their own electricity at that specific site. This cuts down on constructions costs of
underground wiring. This is also common in countries where the grid is not available or is unreliable. These types of systems are also used for security purposes as if the gird fails at specific locations the
lighting will still be available.
Without light , all environment are uninhabitable , without light, no architectural feature can emerge from darkness , a landscape can't find full expression if it isn't properly illuminated . Today , lighting must be blended in with the environment and become an added value , never play the lead .
