The agriculture sector is one of the main driving forces of the economy, yet it is gravely affected by the growing number of industrializations and climate change, resulting in low productivity and food scarcity. This is why innovative farming methods are introduced to farmers to help them slowly adapt and mitigate these problems. Numerous studies regarding aquaponics have been conducted to enhance the quality of food production, but only some of them use renewable energy as source of electricity. This paper discusses how the system, powered by solar energy and has a monitoring website using the Internet of Things (IoT), can help in improving agricultural growth and food security, create entrepreneurial opportunities, and combat the effects of climate change. The growth of the lettuce from the system was compared to the existing aquaponics study from the De La Salle University (DLSU), which resulted in the researchers’ system being ahead by having a 60.89% growth rate in just a week of monitoring. The findings also indicate that insufficient light exposure may result in leggy lettuce and suggest that thorough monitoring of the pH level must be practiced since it plays a vital role in the growth of both lettuce and tilapia.
