The present study was conducted to examine the adoption and impact of solar-based renewable energy technologies in agriculture among farm women of Bikaner district, Rajasthan. The study was carried out in six villages, namely Nokha, Lunkaransar, Kolayat, Sri Dungargarh, Khajuwala, and Chhatargarh, selected on the basis of their geographical location within the district and the presence of solar energy users. The research focused on assessing the use of solar geysers and solar panels for electricity and their impact on agricultural productivity, cost of cultivation, and environmental sustainability. The study was conducted using a survey method with ex-post facto approach employing purposive sampling technique, and primary data were collected from 120 female respondents, with 20 respondents from each village, through a structured interview schedule. The findings revealed that the adoption of solar energy technologies significantly reduced dependency on conventional energy sources and lowered operational costs in agricultural and household-related activities. The study also indicated a positive shift towards eco-friendly practices and improvement in the socio-economic status of the respondents. Major constraints identified were lack of awareness, high initial investment, and inadequate technical support. The study concluded that solar energy played an important role in promoting sustainable agriculture in the arid region of Bikaner district and recommended strengthening awareness programs along with financial and technical assistance to enhance adoption among farm women.
