NorSun provides low CO 2 footprint value NorSun with industry leading CO 2 -footprint French market (grams CO 2 /Watt) French tenders at about 2GW per year, increasing to 3GW - New energy policy announced to expand PV from 8.5 GW installed capacity in 2018 to over 40 GW by 2030 - Installations to increase to over 3.5 GW per year until 2030 French tenders score CO 2 footprint of the modules in addition to price - CO 2 footprint/Watt = 20%-30% of score Other countries to follow EU is evaluating to introduce environmental policy such as ECO-label and green public procurement NorSun in unique position with unprecedented Korea is planning similar program as CO 2 footprint , based on Lifecycle Analysis (LCA) France certified by French authority (ADEME) More countries expected to follow as part of the global push for environmentally friendly solutions - STRICTLY PRIVATE AND CONFIDENTIAL -

NorSun with best CO 2 footprint The French system incentivizes environmental and process improvements. It has created awareness in NorSun to become the greenest possible producer of ingot and wafer. NorSun is working closely with ENOVA (Norwegian Government energy saving agency) to reduce waste, save energy and introduce new energy efficient processes. High quality wafers for highest cell efficiency => improving silicon per Watt Efficient recycling process for silicon off-cut in ingot manufacturing (such as ingot tops, tails, side-cuts and off-spec material) Readily available cooling water reduces electricity consumption for chillers Efficient sawing process with thin diamond wire Thin wafers down to 130µm Minimal use of chemicals - STRICTLY PRIVATE AND CONFIDENTIAL -

Carbon Foot Print roadmap NorSun has developed a CFP roadmap, reducing waste and improving resource efficiency Technical cooperation and development with customers to improve efficiency improving silicon per Watt (currently just 2.7 g/Wp, in the future < 2.0 g/Wp possible) The main CFP activities include High ingot utilization High wafer quality for highest cell efficiency Slicing with 40µm core diamond wire Ultra thin wafer road map Recycling/reuse of silicon kerf (saw dust). Applications include metallurgical industry, feedstock in poly production and the possibility for use in battery anodes. New slicing fluid with low CFP Recycling of slicing fluid NorSun is piloting Argon recycling with good results NorSun is designing their own future hot zone with estimated 15% reduced energy consumption Recycling of potscrap from ingot pulling First 40µm core wire test cut • 125mm wafer, 140µm thickness • MeyerBurger 291 DW saw - STRICTLY PRIVATE AND CONFIDENTIAL - 8
