Abstract

Alongside advancements in photovoltaics (PV) technology, efficient solar farm operation (e.g., strategic panel cleaning) can help lower electricity generation costs in the field. In this work, we study the effects of season-dependent soiling and cleaning on energy yield, revenue, and profit in four locations – Dhaka (Bangladesh), Oregon City (USA), Berlin (Germany), and Rumah (Saudi Arabia). These locations cover a wide range of soiling rates, season-dependent rainfall, cleaning costs, and tariff rates for a broad techno-economic analysis of soiling-affected solar farms. While a two-month cleaning cycle, for example, apparently seems too long for soiling-prone locations (Dhaka and Rumah) – this is too frequent for Oregon City and Berlin due to their high cleaning costs. Therefore, the optimal strategy for maximum profit for the latter two locations is to never clean the panels. Even at optimal cleaning cycle (maximum revenue/profit), there is a profit-loss of 13.28%, 19.97%, 1.39%, and 42.88%, compared with the respective soiling-free rated farm output at these locations. We also show the sensitivity of output and profit to the variations in soiling rate and cleaning cost; farms in Dhaka and Rumah show strong sensitivity due to the high soiling rate and low cleaning costs.

当地经济和季节性清洁周期对污损太阳能发电场产量和利润的影响

随着光伏（PV）技术的发展，高效的太阳能发电场运营（如战略性的电池板清洁）有助于降低现场发电成本。在这项工作中，我们研究了孟加拉国达卡、美国俄勒冈市、德国柏林和沙特阿拉伯鲁马这四个地点的季节性污损和清洁对发电量、收入和利润的影响。这些地点的污损率、与季节相关的降雨量、清洁成本和关税率范围很广，可对受污损影响的太阳能发电场进行广泛的技术经济分析。举例来说，两个月的清洁周期对于易受污垢影响的地区（达卡和鲁马）来说显然太长，而对于俄勒冈城和柏林来说，由于清洁成本较高，清洁周期则过于频繁。因此，对后两个地点而言，获得最大利润的最佳策略是从不清洁面板。即使在最佳清洁周期（最大收益/利润）下，与这些地点各自的无污渍额定农场产出相比，利润损失分别为 13.28%、19.97%、1.39% 和 42.88%。我们还显示了产出和利润对污损率和清洁成本变化的敏感性；达卡和鲁马的农场因污损率高和清洁成本低而表现出很强的敏感性。

期刊介绍： The IEEE Journal of Photovoltaics is a peer-reviewed, archival publication reporting original and significant research results that advance the field of photovoltaics (PV). The PV field is diverse in its science base ranging from semiconductor and PV device physics to optics and the materials sciences. The journal publishes articles that connect this science base to PV science and technology. The intent is to publish original research results that are of primary interest to the photovoltaic specialist. The scope of the IEEE J. Photovoltaics incorporates: fundamentals and new concepts of PV conversion, including those based on nanostructured materials, low-dimensional physics, multiple charge generation, up/down converters, thermophotovoltaics, hot-carrier effects, plasmonics, metamorphic materials, luminescent concentrators, and rectennas; Si-based PV, including new cell designs, crystalline and non-crystalline Si, passivation, characterization and Si crystal growth; polycrystalline, amorphous and crystalline thin-film solar cell materials, including PV structures and solar cells based on II-VI, chalcopyrite, Si and other thin film absorbers; III-V PV materials, heterostructures, multijunction devices and concentrator PV; optics for light trapping, reflection control and concentration; organic PV including polymer, hybrid and dye sensitized solar cells; space PV including cell materials and PV devices, defects and reliability, environmental effects and protective materials; PV modeling and characterization methods; and other aspects of PV, including modules, power conditioning, inverters, balance-of-systems components, monitoring, analyses and simulations, and supporting PV module standards and measurements. Tutorial and review papers on these subjects are also published and occasionally special issues are published to treat particular areas in more depth and breadth.
