A clear sky detection method using the pyranometer GHI measurements is employed to enable forecast validation not just for overall performance but also for cloudy and clear sky periods separately. To potentially improve GHI forecasts, the WRF-Solar GHI values were postprocessed using a Kalman filter (KF) tested for different training days (i.e., from 3 to 42 days) to determine the optimal number of training days that minimize the RMSE. KF post-processing, with the shortest number of training periods (3 days), already provides an MBE (RMSE) reduction of 70 to 94 % (8 to 12 %). The optimal training period (14 for JJA; 42 for JFM) for filtered WRF-Solar GHI forecasts leads to an MBE (RMSE) reduction of at least 64 % (17 %) during cloudy periods. However, KF underestimates GHI values for clear sky periods because of reducing the bias of the dominantly cloudy periods over the site. Results from the study, the first of its kind to assess performance of WRF-Solar and KF over the Philippines, will serve as a basis for a computationally efficient alternative to more expensive higher resolution and multiple ensemble member solar forecasts. Future work intends to focus on applying this method over different topographies in the Philippines, given the availability of irradiance data.</div></div>","PeriodicalId":428,"journal":{"name":"Solar Energy","volume":"283 ","pages":"Article 113050"},"PeriodicalIF":6.0,"publicationDate":"2024-10-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142553752","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}

Real-case boundary conditions are derived through the thorough examination of the overall system, encompassing user demands and operational dynamics. In particular, the study evaluates two distinct building scenarios, <em>i.e.,</em> modern, and outdated buildings, considering both existing and new structures, to assess the flexibility and adaptability of the LHTES system to varying cooling demands. The preliminary system analysis gives a set of boundary conditions for the subsequent storage sizing and numerical simulations. Building upon these insights, the manuscript introduces a novel storage design inspired by tree-shaped configurations. This design – numerically simulated through a finite element code – aims to enhance heat spreading throughout the solid–solid PCM and maximize latent heat exploitation, thereby improving overall system efficiency and performance. The sizing of the storage system results in 487.8 kg, and 382.0 kg, for the modern and outdated building, respectively, and storage efficiency reaches a value of 86.15 % and 71.84 % for the charging phase and 97.70 % and 98.21 % for the discharging one, respectively.

However, limitations such as viewing angle and soiling can affect measurements and decision-making processes. This study investigates the directional emissivity and reflectivity of a poly-Si module under clean and contaminated conditions, using both urban and mineral dirt. A custom experimental setup enabled thermographic inspections using a FLIR SC660 thermal camera across a range of viewing angles (0°to 70°) and temperatures (25 °C to 60 °C). The results demonstrate that emissivity decreases and reflectivity increases with larger viewing angles, with surface temperature exerting minimal impact. Soiling made the surface less reflective, with overall optical trends remaining consistent. These findings contribute to existing literature by addressing the gap in available data on the directional optical properties of poly-Si modules. The results have practical implications for thermal inspections, emphasizing the importance of viewing angles in data interpretation and suggesting adjustments to enhance the rigor of assessments.
