China’s solar industry has hitherto been relying upon Himawari and Meteosat-derived surface irradiance products. Despite the maturity of those products, none provides a complete coverage of China, which implies a series of data issues, such as the inconsistency at product boundaries or limited resolution towards the edge of the field-of-view disks. However, data issues are but secondary, and the lack of autonomous capability of performing solar resourcing is what truly troubles those concerned. China’s latest geostationary weather satellite series, Fengyun-4 (FY-4), has the most advanced technology, but its service commenced only fairly recently in 2017. Hence, to meet China’s immediate needs for solar resources under its radical decarbonization target, which cannot afford to wait for FY-4 data to pile with time, soliciting information from its predecessor series, namely, FY-2, is thought to be apt. In this work, a high-resolution (1.25-km, 1-h) satellite-derived surface irradiance product (HelioFY2) over a twelve-year period (2011–2022) is developed, based on the scanning radiometers onboard FY-2E, −2F, and −2G satellites. A series of analysis as to quantifying the interannual and spatial variability of solar irradiance and assessing photovoltaic potential in China, which has rarely been done before, confirm that the current product can suffice most solar resourcing applications.

This study evaluates soiling’s impact on large-scale PV and CSP systems under identical conditions at Green Energy Park (GEP), Morocco. Three PV technologies (Mono-crystalline, Polycrystalline, Cadmium Telluride) and CSP (Fresnel) were examined, with two PV systems per technology—one cleaned every two days and the other left uncleaned. High-precision techniques, including Tracking Cleanliness System (TraCS) and reflectometer systems for CSP and continuous monitoring of maximal power output with an MPP meter card for PV, measured Cleanliness Index over four months.

This paper proposes an innovative radiant heating system that combines solar photovoltaic technology with graphene-based electrothermal coatings. By utilizing photovoltaic power generation to replace traditional high-voltage drive systems for supplying electricity to the electrothermal coatings, the system reduces building energy consumption while ensuring efficient heating. Based on the excellent conductivity and thermal conductivity of graphene, this system can quickly convert electrical energy into thermal energy and achieve efficient heat transfer through far-infrared radiation. The study was conducted from July to August 2022 in Changzhou, China, where an experimental platform was established to investigate the effects of photovoltaic voltage, photovoltaic current, and coating area on the thermal performance of graphene-based electrothermal coatings. The results demonstrate that the graphene-based electrothermal coating exhibits low saturation voltage and saturation current, with voltage having a more pronounced impact on heating performance. Under optimal conditions, the surface temperature of a 20 × 40 cm heating panel reached 63.19 ℃, increasing the ambient temperature to 35 ℃. As the area of the graphene-based electrothermal coating expanded, the proportion of radiant heating significantly improved, with the radiant heat transfer efficiency of a 60 × 60 cm heating panel reaching 71 %. Economic analysis indicates that the system holds good application potential, with a payback period of approximately 3.87 years and a levelized cost of electricity of $0.0742/kWh. The findings of this study are of great significant for exploring a novel radiant heating approach.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"296 ","pages":"Article 113600"},"PeriodicalIF":6.0,"publicationDate":"2025-05-14","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143947689","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}
