Abstract: This study assessed the impact, usability, and sustainability of the Solar-Powered Irrigation System (SPIS) among 33 farmers in Tabuk City, Kalinga, and Quezon-Mallig, Isabela. Using a quantitative descriptive design, the research found that SPIS significantly improved crop yield, quality, and farm income, while reducing irrigation and energy costs. Most respondents were male, aged 51–60, with modest incomes and limited formal education, highlighting the need for targeted training. Land ownership was high, and crop farming dominated, but many previously relied on costly diesel pumps or rainfed agriculture. While SPIS was rated highly for energy efficiency and integration with existing infrastructure, moderate ratings for ease of use, system reliability, and low scores for training and technical support revealed operational gaps. Institutional and community support was strong, with widespread willingness to recommend SPIS and confidence in government investment. The study concludes that SPIS offers substantial benefits for smallholder farmers but recommends enhanced technical training, local support hubs, improved financial access, infrastructure upgrades, stronger policy support, and greater community engagement to ensure long-term sustainability and equitable access.
