To support the potential contributions of ordinary citizens, this research analyzes the factors influencing the deployment of residential and small-scale solar PV systems in Japanese municipalities, providing local government units with data-driven insights to formulate strategies for expanding solar energy. A Random Forest Regression model assesses each factor’s impact on municipal solar PV capacity share. SHAP values highlight feature importance and visualize the most influential independent variables. Results indicate that local energy demand is the primary driver of solar PV installations. For residential systems, economic factors such as taxable income serve as secondary drivers, while high land values impede growth. In the case of small-scale installations, land availability becomes a critical limiting factor, particularly in regions with limited land, even when energy demand remains high. The study demonstrates that proactive local governments can overcome economic and land-use challenges through targeted subsidies, strategic partnerships, innovative use of public spaces, and strict enforcement of land-use regulations. By highlighting the significance of local energy demand and citizen involvement, this study offers valuable insights for policymakers to prioritize areas with lower energy demand and implement targeted supportive policies, thereby fostering a more balanced distribution of solar PV installations. Japan’s case may serve as a reference for optimizing solar PV deployment strategies globally, contributing to the broader discourse on small-scale renewable energy expansion.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"287 ","pages":"Article 113175"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143093300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"工程技术","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The concentration of the melanin was constant at 0.1 mg/ml of dimethyl sulfoxide (DMSO). Three different amounts of PSP were added 3, 9 and 20 mg in 1 ml of melanin to obtain three colloidal solutions of melanin/PSP.

The PL spectra have different intensities due to the each concentration of the PSP and under UV radiation three distinct colors could be appreciated. However, the emission is correlated to the down conversion effect of the PSi and the high intensity luminescence corresponds to the Melanin UV absorption and the passivation of the PSi particles due to the chelant property which is appreciated with the transmission electron microscope micrographs.
