A: 15-30 days, depend on the order quantity.

A: Sample is free, but freight cost should be paid by clients.

A: We accept L/C, T/T, Western Union

A: The operating life of the photovoltaic system is 25 years. The household system is inspected once or twice a year, mainly to check whether the circuit is damaged to ensure the system's safety and normal operation.

A: Generally, the components do not need to be replaced if they are not damaged in 25 years. The system will still be operational after 25 years, and the replacement depends on the customer's wishes.

A: It depends on the specific project, the main area is photovoltaic array. Under normal conditions, the entire system equipment is placed as centralized as possible to save costs, and the equipment installation location can be determined according to the project site. Inverter electric boxes, etc. can generally be wall-monted, and equipment can be mounted on walls or prefabricated brackets in idle locations which may be not necessary to add equipment rooms. Besides, if some projects only need one or two inverters and one junction box, there is no need to set up a machine room. Inverters and DC parts can be placed next to the photovoltaic array or other free locations. The grid-connected box/cabinet is generally placed near the grid-connection point or in the electric room. For commercial buildings or factories, etc., the devices can be placed as long as the electrical room has a place. However, we will be pleasured to share our professional advices with you.

A: Solar photovoltaic systems can be divided into the following three systems according to the installed capacity of the system:
1.1 Small system, a system with installed capacity not greater than 20kW;
1.2 Medium-sized systems, systems with installed capacity between 20kW and 100kW;
1.3 Large systems, systems with installed capacity greater than 100kW.
