The mass production average conversion efficiency of TOPCon cells (PE-poly route) exceeded 26%! On September 3rd, with the superposition application of SE (Selective Emitter) laser doping technology, the mass production average conversion efficiency of DAH Solar TOPCon cells, has reached 26.05%, refreshing the industry record once again, reaching the industry leading level, showing the "DAH speed". On June 9, DAH Solar and SHENZHEN S.C issued the joint announcement, that DAH Solar's TOPCon cells manufacturing base set the climbing record of 97% yield and 25.4% efficiency in just 23 days (not on SE at that time), which attracted high attention from the whole industry. Subsequently, through the continuous optimization of each technical links and materials, by the end of July, the mass production average conversion efficiency of DAH Solar’s TOPCon cells has reached 25.8%. At the beginning of September, with the equiped of laser SE equipment and technology, the conversion efficiency improved by another 0.25%, creating an industry-leading level by 26.05%. DAH Solar has always focused on R&D and organization development.Not only in terms of module and PV system product innovation, we have successfully launched the global patent Full-Screen PV module and the world's first integrated PV system SolarUnit, and also forward-looking developand layout of cells technology, with absolute advantages to achieve the full production of TOPCon cells and the high-speed climbing of conversion efficiency and yield. In addition to that, DAH Solar has also precipitated for many years in terms of crystal pulling and slicing technology, laying a good foundation for further improving the layout of industrial integration.

advantages of ON-Grid solar system -4KW solar power system
1. become money with Our great sun
"Your solar panels will often generate more electricity than what you are capable of consuming. With net metering, homeowners can put this excess electricity onto the utility grid instead of storing it themselves with batteries."
2. utility grid as a virtual battery
"The electric power grid is in many ways also a battery, without the need for maintenance or replacements, and with much better efficiency rates. in other words, more electricity goes to waste with conventional battery systems."
3. higher efficiency
“With power classes up to 325 Wp and up to 16.5% efficiency it’s the most powerful 72-cell standard module on the market, ideally suited for obtaining maximum yield from smaller rooftop areas.”
