FAQ
Q:Can I have a sample order?
A:Yes, we welcome sample order to test and check quality.
Q:What about the lead time?
A:Sample needs 3 days, mass production time needs 5-7 weeks, it depends on order quantity.
Q:How do I know whether you've shipped my order or not?
A: Tracking No. will be offered as soon as your order be shipped out. Before that, our sales will be there to check the packing status, photo you the done order and let you know the forwarder picked it up.
Q:Do solar panels need maintenance?
A:Solar panels only need maintenance two to four times a year, but check your solar companies manual for panel specific maintenance care. Fall and spring serve as good times to perform maintenance work because panels can need cleaning following winter where dust and debris can accumulate.
Q:Can I pressure wash solar panels?
A:It's best to avoid using a pressure washer, scourers or harsh cleaning chemicals when it comes to cleaning your solar panels, as they may damage the system or surface of your panels.
Q:How long does it take for solar to pay for itself?
A:six to ten years
The most common estimate of the average payback period for solar panels is six to ten years. This is a pretty wide range because there are many factors that will influence the number of years it can take to pay off your panels and the monthly savings you can expect.
