Ahead of the results season for the renewable energy sector Nomura Securities has topped the solar sector to shine brightest."We expect a strong Q2 [second quarter] in the solar sector, while the US market weakness is set to continue to affect Q2 in the wind sector. Europe will make up some of the weakness. Centrotherm, PV Crystalox, Q-Cells stand out as offering a positive risk/reward balance," suggests Nomura analyst Catharina Saponar."We expect improved order flow and a positive impact from euro weakness across the solar equipment segment, but rather than leading to guidance upgrades, we think this will fully underpin 2010 guidance that up to Q1 has not been covered through backlog in all cases. We also see PV Crystalox benefitting from strong wafer markets," the broker said.
