Solar energy is a renewable resource which is inexhaustible until the sun sets. Even though it plays a major role in generating green electricity, solar module cleaning is a water intensive process. Cleaning of solar panels is essential for efficient power generation. In its efforts to make green energy generation sustainable, Adani Green Energy Limited (AGEL), is focusing on lowering the water footprint of its solar portfolio by introducing advanced technologies.
AGEL is deploying water-free robotic cleaning system to minimize water consumption for the maintenance of the solar modules. AGEL plans to implement this across its operational solar, hybrid sites (solar capacity of hybrid) and its future projects, especially in arid and dry regions like Rajasthan & Kutch in Gujarat, where renewable water sources are scarce. This will reduce water usage for solar module maintenance to zero.
Currently, the robotic cleaning technology has already been adopted at ~30% of AGEL’s operational solar and hybrid plants i.e., 2,070 MW of 7,043 MW (solar + solar component of hybrid plants). This will save ~283 million litres of water annually, which is equivalent to water requirement of ~2.7 million households every year.
AGEL is likely to ink an agreement of ~0.80 million USD with an Israeli firm for supply and installation of robots. The order to be placed will be for a 150 MW under construction site in Phalodi, near Jodhpur. Installation work has already started at the hybrid plant in Jaisalmer.
Over the years, AGEL has engaged robots to counter dust accumulation on solar panels and modules. These robots use water-free technology that is both environmentally friendly and enhances the energy output of solar panels. Keeping in mind the growing concerns around scarcity of freshwater resources, AGEL has been undertaking several water stewardship activities, aligned with UN sustainable development goals (SDG) 6 on sustainable management of water.
During the recent H1 FY24 earnings announcement, Amit Singh, the CEO, Adani Green Energy said: “In line with India’s decarbonisation goals, we remain committed to deliver in excess of 45 GW by 2030. Adani Green continues to have the largest operating renewable portfolio in India with 8.4 GW capacity. We are ramping up our execution capabilities as we prepare for our next phase of growth.”
