Quick answer: A 1KW solar system of this configuration produces about 6.3KWH per day from 3x350W monocrystalline panels and driven by a 1KW/1.5KVA inverter. Built by Mars Solar (factory since 2008), CE/ROHS certified, 25-year panel life, shipped factory-direct to 130+ countries.
Recently, the Biden administration in the United States suspended tariffs on photovoltaic panels imported from four Southeast Asian countries. This is in fact part of a longstanding dispute between the United States and China. Proponents say the decision will speed up the U.S. transition to renewable Solar System Panels energy -- and, at the same time, will certainly help industries in the Southeast Asian nation. In fact, U.S. consumers now install imported photovoltaic panels on their homes or commercial buildings, most likely from Southeast Asian countries.

More than 85 percent of all PV panels entering the U.S. market last year came from four Southeast Asian countries: Malaysia, Vietnam, Thailand and Cambodia, according to U.S. consultancy Rystad Energy. Trade data shows that Malaysia and Vietnam top the list with $2.5 billion worth of PV exports to the US in 2021. Thailand exported more than $1 billion of photovoltaic panels to U.S. customers last year, while Cambodia's exports were about a quarter of Thailand's, or $250 million. U.S. Commerce Department investigators suspect that Chinese companies have been using Southeast Asian factories to circumvent U.S. import tariffs on Chinese PV products — in some cases by simply assembling products that are actually made in China in Southeast Asia. The Commerce Department investigation will continue — the Biden administration is also using the U.S. Defense Production Act to kick-start the production of photovoltaic panels in the U.S. — but it will undoubtedly take some time. A statement from the White House said that photovoltaic products from Southeast Asian countries will not increase new tariffs for the next two years. At the same time, the United States will accelerate the establishment of a domestic photovoltaic industry chain."

It is expected that by 2030, photovoltaic modules and cells produced in the United States will be able to enjoy the SEMA (US Photovoltaic Industry Promotion Act), which provides tax subsidies and relief. .
