You will be working alongside a highly successful team who deliver amazing innovative work in the solar PV industry! The solar industry needs a global end-of-life partner to restore, renew and ultimately recycle yesterday’s solar panels for tomorrow’s clean energy projects. SOLARCYCLE aims to be the partner of choice for solar asset owners looking for a responsible solution to their end-of-life system needs.

Solar power is one of the most powerful tools humanity has in our fight against climate change. But for solar to truly scale to its full potential, we need to create renewable supply chains and a vibrant secondary market for upcycled panels and recycled materials. SOLARCYCLE was founded by experts and advocates in solar, climate and circular economy. Our investors come from the frontlines of the solar industry, including the founders of SolarCity, SunPower and Nextracker. This is the next frontier - ensuring a cleaner, more sustainable and domestic supply of the critical minerals needed for the next wave of solar. We exist to make clean energy massively scalable and even more sustainable by radically advancing recycling technology and infrastructure for the solar industry. If this resonates with you, we really want to meet you.
