LONGi was a company founded in 2000 that specialised in the manufacture of silicon products. It progressed to break world records in solar efficiency multiple times and is now one of the fastest growing photovoltaic companies in the world due to their ability to produce one of the world’s finest panels. Their panels have stood out among the world’s most reliable as reported by the independent PVEL review. LONGi panels are one of our favourite panels to install and to this day we have not had a single complaint or failure from their usage.
