As a professional solar photovoltaic system supplier integrating production, design and sales, we, GREENSUN, was founded in 2003. Earlier, we have been doing OEM for tier 1 brands with excellent product quality and competitive prices. In 2017, we decided to start our own brand and export ourselves. From the beginning of the annual export volume of 500,000 US dollars, it has now exceeded 300 million US dollars. The exporting countries have now exceeded 100 countries from the first 10 countries. The total installed solar system has exceeded 120GW. 1: Solar Panel. Our first factory mainly produces solar photovoltaic modules. Twenty years ago, it was mainly the production of 3BB's polycrystalline solar photovoltaic panels. With the advancement of technology, the production equipment has been continuously upgraded, and it has begun to produce 5BB monocrystalline and polycrystalline solar photovoltaic panels, until the current 9BB, 12BB half-cells solar photovoltaic panels. At present our annual production capacity can reach 5GW. Products have TUV, IEC, CE, ISO, INMETRO, UL and other related certifications. At the same time, it also maintains cooperation with LONGI, RISEN, QCELLS, TRINA, CANADIAN and other companies. 2: Lead Acid Battery. In addition to solar photovoltaic panel production plants, we also have lead-acid battery and lithium battery factories. The lead-acid battery factory currently produces 2V and 12V batteries, including but not limited to AGM, GEL, OPZV, OPZS and other cycle batteries. The current annual production capacity exceeds 1 million units. 3: Lithium Battery. The lithium battery factory currently produces 2V, 12V, 24V, 48V, ...720V and other lithium iron phosphate batteries. Lithium batteries can currently communicate with most inverters on the market, such as Deye, Sungrow, Growatt, Sofar, Invt, and Solar Ark.....etc. Battery certifications include MSDS, CE, ISO, UN38.3, UL and more. Cells come from our partners, including BYD, CATL, ,, etc. Each product has undergone a number of rigorous tests before leaving the factory to ensure that our customers can ensure flawless work after receiving the goods. We can not only provide individual products to customers, but also design and provide a complete set of suitable solar energy system solutions according to the specific requirements of customers.
