“We are committed to developing and operating utility-scale solar PV projects that provide clean, infinitely renewable solar energy to the homes, businesses and schools in the communities that we serve,” said Sean McCloskey at Penn Energy Renewables Ltd. “As a developer and long-term investor in solar PV projects, we were impressed with Canadian Solar’s full array of offerings, which include modules manufactured in Ontario, EPC services and the provision of long-term operations and maintenance services.”
