Renewable energy with adequate utilization can quickly contribute towards the human development and economic sustainability of a country. Solar energy shares a major portion of renewable energy resources and is rapidly becoming a reliable and affordable solution to overcome energy crisis in underdeveloped countries. The solar Photovoltaic (PV) module technology is steadily improving with fast demand from different sectors ranging from home, office, agriculture and industries. The environmental effects on the modules in the form of dust accumulation in countries with high irradiance severely affect energy transmittance and further adds to the overall power loss. The low-cost micro PV systems ($\ll 5$ kW) offered in these countries are further effected by the lack of autonomous cleaning system, resulting in significant drop in the power efficiency. Here, we have developed an Automatic Self Cleaning Mechanism (ASCM), which is cost-effective, efficient and only accounts for $10-15\%$ of the actual installation cost of the PV module. The experimental performance comparison of ASCM shows a $35\%$ enhancement in the output efficiency by avoiding the impact of solar degradation without its use. The designed solution provides an affordable, low-cost automated self cleaning mechanism for micro PV modules.

充分利用可再生能源可以迅速促进一个国家的人类发展和经济可持续性。太阳能占可再生能源的很大一部分，并且正迅速成为克服不发达国家能源危机的可靠且负担得起的解决方案。随着家庭，办公室，农业和工业等不同部门的快速需求，太阳能光伏（PV）模块技术正在稳步提高。在辐照度高的国家，以粉尘积聚的形式对模块产生的环境影响严重影响了能量传输，并进一步增加了总功率损耗。低成本微型光伏系统（$\ll 5$ 在这些国家/地区提供的功率（kW）进一步受到缺乏自动清洁系统的影响，从而导致功率效率大幅下降。在这里，我们开发了一种自动自我清洁机制（ASCM），该机制具有成本效益，高效且仅占$10--15％$光伏组件的实际安装成本。ASCM的实验性能比较显示$35％$通过避免不使用日光降解的影响来提高输出效率。设计的解决方案为微型PV模块提供了一种经济实惠的低成本自动自清洁机制。
