As a result of advances in manufacturing techniques and battery longevity, photovoltaic system costs have decreased while efficiency of solar panels has increased. Cost reduction in both conventional and renewable energy systems depend on effective energy management. To determine how an energy management system for solar systems affects cost-reduction, this study introduces one. Starting by researching and analyzing the solar energy systems and find the parameters that affecting the high cost of the systems, trying to control the parameter that could be controlled, that leads to reduction will be around 30% of use1 saving day as a replacement for 1.5, 46.5% when 1 instead of 2 days, and 62.9% of uses 1 instead of 3 days. To further decrease solar energy system costs, this project utilizes weather forecasting to predict energy production. It implements energy management techniques to optimize energy usage and minimize the need for storage. By optimizing energy consumption, the goal is to enhance solar energy accessibility and affordability for consumers.
