Sunnova Energy International Inc. recently purchased the SunStreet Energy subsidiary from Lennar Group in April and entered into a partnership agreement with the national homebuilder to provide integrated solar power system installations. Sunnova has partnered with 30 quality homebuilders nationwide and installed more than 45,000 solar power systems across 600 communities. New homebuyers have an option to either lease the power generated by the solar panels on their rooftop or own the panels and power system outright as part of the overall price of the home. Under a Sunnova LeasePlus agreement, there are no upfront costs for the solar panel system installation. The homeowner pays a flat monthly fee to Sunnova for the power provided by the panels and maintenance and remote-monitoring services that are included.
