Onsite checks had been carried out in line with IEC 61724: Photovoltaic System Efficiency Monitoring. The take a look at result’s as follows:
As proven, the all-time highest precise PR was 82.44%, and the seven-day weighted common was 80.39%. Based on the PV system report submitted to the supervisor for overview, the simulated PR for July was 76.6%. The precise PR is 3.8% larger than simulated.
How did this PV plant exceed expectations so dramatically? The undertaking makes use of Risen Power 330 W polycrystalline PV modules, Huawei SUN2000-185KTL string inverters, and Arctech Photo voltaic Skyline 1V84 trackers. The string inverters work with the trackers, and the PV modules transfer by monitoring the solar, making certain the optimum standing of every PV string within the plant. The undertaking proprietor stated Huawei’s string inverters offered excellent efficiency in making certain the environment friendly and dependable operation of the plant.
Huawei inverter’s multi-MPPT characteristic may also help reduce the impression of PV string mismatch throughout dusty and cloudy climate. A 3.5 MW PV array helps 170 MPPT routes to make sure that every PV string works at its optimum, which in flip brings larger power yields. Not solely this, however Huawei SUN2000 sequence string inverters can function over a large temperature vary, which is befitting to environments with each extremes of cold and hot similar to Kazakhstan. They’ll run stably within the temperature vary of –40°C to 60°C, with the provision reaching over 99.996%. Extraordinarily scorching or chilly circumstances would normally pose extreme challenges on elements. Huawei employs excessive element choice requirements and patented warmth dissipation applied sciences to make sure the reliability of all elements, even in tough or extreme environments.
As well as, Huawei string inverters use low energy consumption management expertise, energy provide expertise with a large enter voltage vary, and energy element shutdown peak suppression expertise. In addition they help an working voltage vary as huge as 500–1500 V. A decrease working voltage decrease restrict allows inverters to start out early and shut down late on daily basis, which permits them to generate extra electrical energy.
The success of this undertaking is inseparable from the meticulous design and optimization of Risen Power’s Abroad Challenge Technical Workforce based mostly in China. Jeff Lv, Technical Director, was on website personally for inspection and analysis. Below his steering, the technical group of Risen Power compares greater than 100 system design options with automated configuration and loss algorithms, and analyzes the price and profit sensitivity. The group optimizes and selects the price construction of every undertaking. The modular, highly effective, and succesful answer design ensures a steadiness in undertaking price and high quality. The corresponding steadiness created between price and power yield is the important thing to the excessive power yield of the undertaking.
Based on knowledge from the Ministry of Power of Kazakhstan, within the first quarter of 2020, the nation generated 548.4 million kWh of electrical energy utilizing renewable power, 35.7% of it generated from PV. Within the Idea of Transition in direction of Inexperienced Economic system, the Kazakhstan authorities proposed to extend the proportion of electrical energy generated from renewable power to three% by 2020. We imagine that extra PV crops with sudden PR will make the way forward for Kazakhstan’s PV market panorama brighter.
