In the vast, remote landscapes of the North, where diesel generators have long been the backbone of electricity supply, a new study is challenging the status quo. Researchers, led by Nikolay P. Mestnikov, have been exploring the potential of manual tracker units in photovoltaic (PV) micro-power stations, offering a promising alternative to reduce fuel consumption and carbon emissions.
The study, published in *Известия Томского политехнического университета: Инжиниринг георесурсов* (Tomsk Polytechnic University Journal: Engineering of Georesources), focuses on the practical application of manual trackers in autonomous power systems. These trackers, which adjust the orientation of PV panels to follow the sun’s path, can significantly increase electricity generation. “The capital cost of manual tracker units is 70–80% less than their automatic counterparts,” notes Mestnikov. This cost-effectiveness is a game-changer for remote settlements where budget constraints are a major challenge.
The research reveals that manual tracker units can boost average daily electricity generation by 17–18%, provided the PV panels are adjusted hourly. This increase in efficiency translates to substantial fuel savings. In the village of Toyon-Aryy, for instance, introducing manual tracker units in a 20 kW PV plant could save up to 8.8 tons of diesel fuel annually. The payback period for such an investment is estimated at up to 11.7 years, making it a viable option for long-term energy planning.
Moreover, the environmental benefits are substantial. The study calculates a reduction in CO2 emissions by 27.7 tons per year, a significant step towards mitigating the carbon footprint of remote energy systems. “The obtained results of applied research can be used to update the existing list of technical measures to improve PV-power plants located in the North,” Mestnikov explains.
However, the study also highlights the limitations of manual tracker units. High labor costs make them impractical for small and large-capacity solar energy facilities. This nuance is crucial for energy sector professionals to consider when evaluating the feasibility of implementing such systems.
The findings of this research could shape future developments in the energy sector, particularly in remote and northern regions. As the world shifts towards renewable energy, the integration of cost-effective solutions like manual tracker units could play a pivotal role in reducing reliance on fossil fuels and lowering carbon emissions. The study’s recommendations for sustainable operation of manual tracker units provide a roadmap for energy providers and policymakers to enhance the efficiency and environmental performance of PV power plants.
In an era where sustainability and cost-efficiency are paramount, Mestnikov’s research offers valuable insights and practical solutions for the energy sector. As the industry continues to evolve, such innovations will be key to meeting the challenges of energy supply in remote and environmentally sensitive areas.
