Distributed photovoltaic adoption in rural Shandong, China: status, challenges, and influential factors

Distributed photovoltaic systems (distributed PV) enable rural households to replace traditional energy sources, reduce their household carbon footprint, and generate additional income. Due to the multiple benefits, China increasingly prioritizes developing distributed PV in its rural areas. However, the overall status, primary challenges of distributed PV in rural China, and how regional social and economic factors contribute to adoption choices of distributed PV remain largely uninvestigated. Here, we aim to provide insights into the above issues and offer a basis for policy recommendations that can facilitate the adoption of distributed PV, drawing from Shandong Province’s experience. This study is based on a survey conducted in 2023, encompassing a total of 169 households across 36 villages in Shandong Province. Our results show that 43% of the households have embraced distributed PV with various system standards employed. We also find that rural households in Shandong Province encounter challenges engaging in distributed PV systems, such as inadequate policy support, significant heterogeneity of policy promotion among villages, a predominant emphasis on construction rather than management, and an extended payback period. We suggest that future attention should be paid to households that have not experienced extreme weather events and those that have not yet engaged in related low-carbon environmental activities. Local village officials should take the lead in spearheading policy promotion activities to enhance villagers’ awareness and enthusiasm. Besides, efforts should be directed towards guaranteeing the availability of high-quality distributed PV systems with consistent standards.
