28 COST & ENERGY EFFICIENT PV INVERTERS Panel level electronics Safer systems More energy Easy installation Lower cost

29 Next-generation PV Inverters Solar PV inverters convert DC (from panels) into AC (for the power grid) Optistring PV inverters: 1. Take a game changing, cost efficient, distributed (panel level) approach 2. Are high efficiency, safety-compliant and cost ½ to ¼ of competitors alternatives 3. Enable positive business model change for large panel manufacturers 4. Fits the market trend (rooftop, safety ) and panel manufacturers downstream push 5. Will drive module level electronics penetration beyond current projections Optistring status: Joint development with a major global panel manufacturer Finalising contract manufacturing partners Pilot installations TAM of 4GW or 640M (2016) GW Anually installed capacity & Optimizer power share Historical Forecasted Optimizer power share Optistring history & team: 20 Founded late Based on / spin-off from KTH Power Electronics research 0 8 employees + 4 master students 2 Angel Investors / Board Members; exit experience (Dialog Semiconductor, TranSiC) ,00% 7,00% 6,00% 5,00% 4,00% 3,00% 2,00% 1,00% 0,00%
