If it is a megawatt photovoltaic power station, it is recommended to directly find EPC contractors, who will find someone to design, and the general units and individuals do not have design qualifications;
If it is a photovoltaic street lamp, household photovoltaic equipment, or
If it is 10 kW ~ 100 kW construction equipment, you can find equipment suppliers, construction departments and EPC contractors to see if it is convenient for you.
Generally speaking, few people will ask someone to design it alone, and the cost will be higher.
