FAQ
Q: What equipment does the commercial solar power system include?
A: Basic configuration: solar panel, inverter, bracket, cable and installation accessories, etc. For large power plants, transformers, distribution cabinets and other auxiliary equipment are also required.
Q: What is the installation area of a solar power system?
A: It depends on the actual area available on your roof. Generally, 10 square meters are required for a 1 kW system.
Q: Can a distributed photovoltaic power generation system be installed in commercial housing?
A: Yes. You need to explain the situation to the residents in your building and the property management department. The application form needs to be signed by the residents and sealed by the property management department.
Q: How is a household photovoltaic system put together?
A: First of all, we need to collect basic information from you, including the type of housing structure (residential or commercial), roof structure, roof area, monthly electricity consumption, and so on. Based on the above information, we will design the most economical system scheme for you to maximize the benefits.
Q: How heavy is the unit, and what are the mounting/installation requirements?
A: The 250kW model weighs under 111 kg, and the 330kW/352kW models weigh under 113 kg, with compact physical dimensions of 1159 × 828 × 366 mm. Given the power density, it is highly compact but requires mechanical lifting equipment or a 3-4 person crew for rack/wall mounting on steel structures.
