Let's learn, elevate and sustain together! Brief #11 : ?????????????? ?????????????????????? ?????? ???????????????? ???? ?????????? ???? ??????????????? In trend, the manufacturers' performance/power warranty is typically 25 years and is absolutely based on type of the cell technology and making process. This standard term might deviate when the product is getting used. The following factors are those involving in the lifespan deviation. ?The manufacturer provide the performance warranty chart which depicts the annual degradation. This factor is similar to the wear and tear losses in mechanical systems & self-discharge in batteries, or called as aging. ?The efficiency drop due to losses like Potential Induced Degradation(PID), Light Induced Degradation(LID) etc. are ultimately deviating the span of usage which are getting considered by the R&Ds to reduce them. ?Stringing - Improper string lengths and improper parallel arrangement can affect the power efficiency equally adding the degradation. - Designing the string with different type of modules, even though having same V-I characters, without an optimization affects each modules performance. - Choosing cable size other than the required one will derive losses in multiple ways. ?The environmental factors like temperature, wind loads, pressure are considered before selecting the module for the system. When the modules don't follow the geographic situation, will get affected later like voltage and current drops due to temperature variations. ?Irregular maintenance - Due to particle accumulation over the surface, the power generation gets worst increasing the degradation over the time. - Cable connections especially the MC4 should be analyzed - Fixations of the solar structure and their stability.

NexWafe The manufacturing process to turn high-purity polycrystalline silicon into silicon wafers is by far the most energy-intensive and time-consuming part of the value-added chain of silicon-based PV modules. The epitaxial growth of wafers directly from the vapor phase can skip over this chain and therefore offers considerable energy saving potential and, currently, often the chance to cut down on carbon emissions. This also significantly reduces manufacturing costs. NexWafe has developed this process to industrial maturity. EpiNex wafers have a very high material quality, which enables the same solar cell efficiency as high-quality, conventional monocrystalline wafers. The proprietary process also enables the production of very thin wafers less than 100 μm thick. https://lnkd.in/diuu-dkd ? ?????????????????? ???? ArcelorMittal Construction The French building materials company produces heat-insulating standing seam sheet metal roof elements, also known as sandwich roof panels, which are equipped with high-performance PV modules with plastic covers and TOPCon cells. These panels can be used to efficiently build or replace entire roofs for heated residential and commercial premises up to a length of 11 meters with an output of 2.2 kW. The additional weight of this BIPV solution contributes just 2.5 kg/sqm, compared to 12 kg/sqm in the case of conventional PV modules including their required substructure. Likewise, the lack of glass and substructure reduces the carbon footprint by 25%. https://lnkd.in/dMMZgy6T ? ?????????? ?????????????? ???????? ???? SMA Solar Technology AG With the Sunny Central FLEX, SMA has developed a modular platform that brings together a DC-DC converter, inverter, medium-voltage transformer and switchgear in one 40-foot container. The platform makes it possible to carry out grid connections for large photovoltaic installations, batteries or fuel cells/electrolyzers. SiC-MOSFETs are used as semiconductor switches, resulting in high system efficiency. https://lnkd.in/d_vGyiud #TheSmarterE #Intersolar #AWARD

Let's learn, elevate and sustain together! Brief #2 : ???????????????????????? ?????????????? ?Usually called as Solar Panels, made after a number of manufacturing processes of the most abundant element 'silicon'. Rated in watts like 440W, 500W, 540W etc. ?A single cell is produced, then combined in series and parallel to design a single module, that provides desired electrical characteristics (voltage and current), applicable in real-time. ?Based on cell crystalline structure and technology on how it is made, differentiated as Mono, Poly, Thin-film and PERC, TOP-CON, HJT etc. respectively. ?It is nothing but a huge (say.6 feet tall) photo-diode, pushing the electrons of the crystalline atoms to make current flow when photons from the sun's radiation hits on its surface, with such electro-chemistry the solar energy is converted into electricity. ?Brought up with an conversion efficiency between 15-25% and this gets increased/varied as per technologies like bi-faciality. Also this efficiency will be improved as researches being conducted on elements used with Si and its alternatives. All is well!

Am humbly proposing and update to the design of the turbine blades at #MeroweDam to a helical design. This update could help increase the current production efficiency of 48%, leading to an expected increase of up to 20%. ?? Expectations: - Current Production: 600 MW - Expected Increase: 20% - Production After Update: 720 MW? This improvement will not only enhance efficiency but also provide more electricity, which will have a significant impact on the market. Increased availability of electricity implies lower prices, fostering a well-managed and directed rise in consumption, particularly in industrial and agricultural sectors. Moreover, improving electricity efficiency can lead to reduced production costs for businesses. Lower energy costs can translate into lower product prices, making them more competitive in the market. This can stimulate demand and contribute to sustainable growth.

What Is the Hotspot Effect on Solar Panels? What Causes It and its Impact The hotspot effect refers to?localized areas of overheating?on the surface of individual solar cells within a solar panel. This phenomenon occurs when certain cells in a panel generate less electricity than other cells, leading to an?imbalanced?circuit of the panel.? Inside the imbalanced circuit, typically in series connection, the underperforming cells become ‘reverse-biased’, which?dissipate part of the energy from adjacent cells as heat instead of?converting it into electricity. Several factors contribute to the formation of hotspots on solar panels: Shading: This is a very common cause. Objects like trees, buildings or other tall structures can cast shadows on parts of a panel. This results in?lower generation in shaded cells, then the hotspots. Accumulation of Dirt and Dust: When various residues accumulate on the surface of solar panels and block sunlight from reaching the cells, the cells would function inefficiently, leading to increased temperature and hotspot formation. Material & Manufacturing Defects: If there are deviations in the manufacturing materials of the cells and imperfections during the manufacturing process such as poor soldering, hotspot effect can occur. Poor Cooling Design & Extreme Weather: A solar power system should be integrated with proper ventilation or cooling mechanisms to maintain an appropriate ambient temperature for the efficient operation of the panels. Poor cooling design when accompanied with extreme weather, e.g.,?‘hotweaves’, can exacerbate the formation of hotspots Impacts of the Hotspot Effect? Reduced Efficiency & Output: Following the working principle of series connections, hotspots can straightforwardly significantly lower the efficiency and output of the solar panel, as the performance of the panel is impacted by the affected cells. From a broader perspective, the affected cells and panels will subsequently influence the performance of the system, especially if not equipped with?optimizers?or microinverters. Physical Damage: It is not only a cause of hotspot effect, but also an impact of the effect itself. Prolonged exposure to high heat can lead to physical damage to the cells and the panel structure, including the melting of solder and cracking of the protective glass. In certain cases, it could induce permanent faults in the panel. Accelerated Aging: The higher temperature caused by hotspots can result in a faster degradation of the materials of the cells and panels. For example, the polymer used in the encapsulation layer or the silicon in the cells can degrade faster. #HotspotEffect #SolarHotspots #SolarEnergy #Photovoltaics #RenewableEnergy #SolarPower
