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: 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:How many solar panels does it take to run a house?
A:An average home needs between 17 and 21 solar panels to fully offset utility bills with solar. The number of solar panels you need depends on a few key factors, including your geographic location and individual panel specifications.
Q:Do I need permission to install solar?
A:You need only apply for full planning permission (flats) or householder planning permission (houses) to install a solar panel when any of the following apply: it would protrude more than 20cm from the external surface of the wall or roof slope, when measured perpendicularly.
Q:Can I buy solar panels and install myself?
A:The answer is yes. If you can drive lag bolts and assemble prefabricated parts, and if you're willing to spend a day or two on your roof (or not, if you're mounting your panels on the ground), you can install your own solar system.
Q:Is solar panel expensive?
A:Having solar panels installed on your home involves a significant investment upfront. The average homeowner will spend $3 – $5 per watt on their solar panels, resulting in a total price tag between $15,000 – $25,000, though there may be incentives and tax credits available to help lower the overall cost.
