加拿大Enertopia公司获得美国专利商标局颁发的热回收技术专利，该技术旨在解决太阳能电池板过热问题。过热会导致电力输出降低和面板寿命缩短。Enertopia的热回收系统通过收集空气中的水分并将其保持在露点温度，从而提高太阳能电池板的效率。该系统包含一个水分收集层，可促进热量从面板到液体传输系统的快速传递。在缺乏自然水分的情况下，系统可控制水的排放，以确保水分收集层饱和。第三方评估表明，该系统可使能源年发电量提高高达13.8%，月发电量提高高达19.9%。此外，收集的水分还可用于农业灌溉。

☀️Enertopia的热回收系统旨在解决太阳能行业中普遍存在的电池板过热问题，过热会导致电力输出降低和面板寿命缩短。该技术的核心在于维持面板的最佳工作温度。

💧该系统通过在太阳能板背面增加水分收集层，利用水分蒸发吸热的原理，将面板产生的热量快速转移到液体传输系统，从而降低面板温度。在干燥环境下，系统还能控制水的释放，确保水分收集层饱和，提高散热效率。

📈第三方评估机构Thermal Energy System Specialists的评估结果显示，Enertopia的热回收系统能使能源年发电量提高高达13.8%，月发电量提高高达19.9%。这一数据表明该技术在提高太阳能发电效率方面具有显著效果。

Canada-headquartered environmental solutions company Enertopia Corporation says it has been issued patent number 12224704 for its heat recovery technology or heat extractor for solar PV panels from the United States Patent Trademark Office (USPTO).  Enertopia says, “Our Heat Recovery System uniquely addresses a systematic problem in the solar industry; the overheating of panels, which leads to lower electrical output and shorter panel lifetimes.”  It explains that the optimal temperature for the face of a photovoltaic panel is 77°F, and for every degree above or below 77 degrees the current output of the panel is reduced by approximately 0.26%. Of the extra heat that is produced, half of it dissipates off the face of the panel, while the remaining half is transferred to the back of the panel, where temperatures can exceed 140°F. According to the Canadian company, its heat recovery technology captures moisture from the air and retains it at dew point temperatures to improve the efficiency of solar panels. The moisture collection layer is positioned between the panel and the liquid transfer system to facilitate the rapid transfer of heat from the panel to the liquid transfer system. In the absence of moisture not forming naturally, Enertopia’s heat recovery system can employ a controlled water emitting to ensure the saturation of the moisture collection layer. In this way, explains Enertopia, its heat recovery system can facilitate and improve heat transfer from the PV panel thereby improving its efficiency, increasing its lifespan and reducing its degradation. It also helps prevent or limit thermal shock for the PV panels. This moisture collection layer may also feed an agricultural or drip system that allows for irrigation of plants in areas with water scarcity, it adds. Assessed by a 3rd party, Thermal Energy System Specialists, Enertopia says its heat recovery system was found to have prompted up to 13.8%/year increase in energy generation, and up to 19.9% on a monthly basis.
