Developing a System for Climate, Light Frequency Control in Economical Off-grid Vertical Farm using MPPT Solar Charge Controller

Abstract

The goal of this research is to design and build an off-grid smart vertical hydroponic farm. Where Plants are grown in vertical stacks, and specialized nutrient water has been used in the absence of soil. The ideal climate for plants and the amount of sunlight required for photosynthesis were completely artificially controlled. For climate control, the structure has been designed with highly insulating but cost-effective materials. A solar air conditioning system was developed to ensure controlled temperature and relative humidity. To provide the optimal light frequency, led strips were placed on top of the vertical stacks to generate light, which is absorbed by the plant during photosynthesis. A microcontroller controls the frequency of the lights. Because this is an off-grid system, an MPPT (Maximum Power Point Tracking) was also designed to maximize solar panel charging efficiency. Using controlled-environment agriculture (CEA), some tomato plants growth was observed under the artificial light generation where temperature and humidity have been checked periodically. Nevertheless, a survey was conducted on different professional people about the impact of this project on society.
