The electricity generation of solar photovoltaic systems can vary due to a range of factors, including installation location, orientation, sunlight intensity, efficiency of solar photovoltaic panels, and the design and installation methods of the solar photovoltaic system. Solar photovoltaic systems are generally installed on village rooftops and/or open spaces. The structure at the location should be sturdy and not obstructed by nearby buildings, high-rise apartments, and trees. To achieve the best electricity generation, the installation angle and orientation of the solar photovoltaic panels should be inclined and facing south.
BW Green Power provides customers with comprehensive "one-stop" services, from product design and development, project planning, preparation to construction and installation, managing the entire project process thoroughly. Our projects are strictly reviewed and accepted by professionals in Hong Kong (including structural engineers and authorized personnel from the Buildings Department) to ensure complete compliance with legal and regulatory requirements. We are committed to providing customers with the most complete and optimized solutions, specifically designed to create a legal, comfortable, and efficient solar photovoltaic system for village house rooftop units.
Each of our projects has a project manager who follows up on the solar power generation system throughout the process, ensuring that the project is implemented smoothly and completed on time. We select high-quality metal expansion bolts produced by well-known manufacturers, effectively enhancing the load capacity and stability of the brackets, capable of withstanding wind force of level 22, ensuring that the system can operate normally even under harsh environmental conditions without being affected.
We fully understand that your time is precious, and we need to minimize the impact of the construction process on your daily life as much as possible. Therefore, we have adopted advanced rapid construction techniques, and the entire installation process of the solar system can be completed in just 2-3 days, reducing the disruption to your daily life and work, allowing you to quickly enjoy the economic benefits brought by renewable energy and online electricity rates.

Photovoltaic systems installed on rooftops or stairway canopies of village houses must comply with the regulations specified for small-scale environmental and appropriate facilities, and must be properly installed without affecting the structural safety of the building. Village house owners should regularly check and arrange for maintenance of the photovoltaic systems every year.
Only solar photovoltaic systems installed on the rooftops of village houses are considered compliant facilities. Solar photovoltaic systems installed on the ground level of village houses (such as underground or adjacent open space) do not fall within the scope of small environmental and suitable facilities and are not regarded as compliant facilities.
Solar systems installed on rooftops must not exceed 2.5 meters in height, and solar systems exceeding 1.5 meters in height must be certified by a registered person under the Building Ordinance and submit the relevant safety certificates to the Lands Department for record.
The solar photovoltaic system installed on the rooftop of the building must have an average load not exceeding 150 kilograms per square meter. Therefore, we use lightweight and high-strength materials to manufacture the brackets, ensuring the strength and stability of the brackets while minimizing the total weight of the system and reducing the system load.
The solar photovoltaic system installed on the rooftop of a village house, and any part of it (including solar components, brackets, cables, etc.) must not extend more than 750 millimeters from the edge of the external wall.
According to the regulations, solar photovoltaic systems installed on village house rooftops in a continuous coverage manner must not exceed half of the total rooftop area.
Solar energy systems installed on rooftops must be grouped, with each group's coverage area not exceeding 5 square meters, and there must be at least 1 meter distance maintained between adjacent groups.
The retractable solar photovoltaic system is an innovative solar power generation solution, characterized by its ability to adjust the tilt angle and azimuth of the solar components based on actual demand.
The installation of retractable solar photovoltaic systems on rooftops must not exceed half of the total rooftop area when fully opened. Ensure that it does not excessively occupy rooftop space, impacting accessibility and maintenance.
The solar energy system is installed on the stair canopy, with a height from the stair canopy to the highest point of the system not exceeding 1.5 meters, and the average load not exceeding 75 kilograms per square meter.
Before installing a solar system, all unauthorized structures on the rooftop must be removed, including those that have been declared and confirmed by the Buildings Department. Additionally, there should be no unauthorized structures on the rooftop where the solar system is to be installed.
Before installing the solar photovoltaic system, all unauthorized structures on the rooftop must be removed, including those that have been reported to and confirmed by the Buildings Department, to ensure the compliance and safety of the system.
The solar system's brackets can only be installed within the rooftop area; brackets cannot be installed beyond the outer wall or on the eaves.
The bracket must be fully installed within the rooftop area and must not extend beyond the rooftop boundary or onto other building structures such as the outer wall or eaves.
