Project Background: The owners of a villa in a suburban southern city are environmentally conscious. Their daily electricity needs include high-power appliances like air conditioning and floor heating, and they hope to reduce their electricity bills through a photovoltaic system.
Implementation: A 100,000 yuan small- to medium-power photovoltaic system was installed on the villa’s roof. A professional team customized the mounting angle to maximize sunlight absorption, and completed grid connection procedures, enabling a dual-mode “self-use + grid connection” system.
Application Results: The household’s electricity costs were reduced by over 50%, with annual grid connection revenue of approximately 20,000 yuan and maintenance costs of only 2,000 yuan. Over 25 years of operation, the system will reduce carbon emissions by over 30 tons, making it a model for green housing emulated by neighbors.
