Based on the housing information and PV demands you provided, we can provide you with the most complete solar consulting expertise.

1. Site and lighting analysis: You only need to provide the area where the equipment is installed, and we will understand the local natural lighting conditions based on your coordinate position. At the same time, based on the comprehensive analysis of the site conditions you have installed, such as property morphology, presence of tree shade and chimney obstructions, actual available site area, and roof inclination angle, our PV data model can provide a preliminary calculation plan for the installation indicators.

2. Calculation of wiring size: Based on the height of the floor, size of the house, number of rooms and installation information points, as well as other specific electricity consumption information provided by you, we can calculate the required bus length, average line length, and line consumption for your PV distribution equipment. I recommend choosing the appropriate cable type and specification for you. And design reasonable wiring paths to reduce losses and provide you with relatively accurate wiring costs.

3. System capacity estimation: By understanding your local lighting conditions and intended product packages, our PV data model can accurately provide the system capacity and cumulative power generation of PV power equipment within a certain period of time, accurately measuring the power carrying capacity of your equipment. Based on the historical data of your electricity bill and equipment investment cost, a cost-benefit analysis can be conducted on this investment to further calculate the investment payback period, investment output, and cumulative net income. From a financial management perspective, we will demonstrate the economic benefits of installing PV equipment to you.

4. Grid connection design: In the design of grid connection, you need to consider the operability of the equipment, whether it complies with regional standards and specifications, the safety and economic benefits of the system. We can provide professional consulting suggestions in the following three aspects:

(1) Regulatory standard consultation: Ensure that the system design meets relevant regulatory requirements and obtain necessary certifications. The system design should also comply with local power grid regulations and standards. When designing, consideration should be given to the matching of the output voltage and current of the PV system with grid parameters to ensure stable operation of the system.

(2) Electricity protection and monitoring: Design necessary electricity protection measures, etc. In the event of a power outage in the power grid, the PV system can automatically cut off its connection to the grid, prevent backflow, and ensure system safety. Ensure that the PV system will not cause power quality issues to the grid after being connected to the grid. Design necessary communication interfaces for grid operators to monitor and control the operation of PV systems.

(3) Equipment selection suggestion: PV equipment should have the ability to convert direct current into alternating current synchronized with the power grid. We recommend the most suitable inverter and other equipment for you; Design energy metering equipment to accurately measure the electrical energy transmitted by PV systems to the grid.
