SUBSTANCE: Solar energy has become an important green energy and lighting resource in homes especially, in rural areas. However, the challenge is to efficiently and optimally use the available solar energy stored in the battery. This invention and system provides a cost-effective solution to the challenge of managing variable solar energy inputs. The system consists of central energy manager, the controllable intelligent lights and the three-wire bus system. The novelty of the invention is optimal and efficient use of energy by using sub interval ON time (SIOT), Sub interval dim time (SIDT) with the intelligent utilization factor which is calculated using real time data from the points. EFFECT: Optimal utilization of energy using intelligent communication link.
