Climatic changes continue to impact our ecosystems and livelihoods globally. In the past few decades, have experienced an increase in unpredictable and extreme weather events, precipitating to the three planetary crises of biodiversity loss, climate change and pollution. Embu County in Kenya has not been spared from the resultant climate change impacts. Although globally solar energy is promoted as a sustainable source of energy, its uptake in Embu County remains low. The study sought to assess the uptake of solar photovoltaic technology by households in climate change mitigation and identify the determinants of solar photovoltaic technology uptake. Cross sectional data from a sample size of 395 households in Mbeere- north Sub County in Embu County was collected using data collection tools including questionnaires, interviews, and observations. Purposive and simple random sampling was employed to select the respondents for inclusion in the study. After data collection, qualitative and quantitative data analysis methods were employed to analyze the data including SPSS (statistical package for the social sciences). The results indicate an overall increasing temperature and overall decreasing rainfall in Embu County. Income demonstrated a greater influence compared to other factors in determining the decision to adopt solar appliances at p =0.397. A significant proportion of respondents (36.9%) reported having limited awareness of climate change and its impacts. Social and mass media were main sources of climate information. There was a positive significant correlation between respondents who displayed awareness of climate change and its impacts and the adoption of solar energy and awareness on solar energy adoption as a solution to climate change at p values of 0.348 and 0.140. The results assisted in assessing the uptake of solar photovoltaic in climate change mitigation in Embu County and identify the determinants driving households on the uptake of solar photovoltaic technology.
