Short interest in solar stocks mainly dropped in the final two weeks of September, with two notable exceptions. Yingli attracted some additional short interest, as we suggested it would, and SolarCity’s short interest jumped significantly. While solar PV installations continue to rise in the United States, SolarCity has a lot of competition and that is squeezing both revenues and profits. The company announced on Wednesday that it had acquired a component maker, Zep Solar, and that might help it lower its costs and boost its margins.
