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:How big is a 400w solar panel?
A:The dimensions of an average 400 Watt solar panel are about 79” X 39” X 1.4”. The 400 watt solar panel size and power output ratio make it a good option for solar installations with space constraints.
Q:Is solar a good investment?
A:Solar panels are a good investment for many US households, especially those with ample sunshine and high utility rates. Going solar can lead to hundreds of thousands in energy savings over the 25-year lifespan of a system and can increase your home value.
Q:Do solar panels work at night?
A:Do solar panels work at night? No, they do not. However, there are a few ways that your nighttime power usage can be offset by solar produced during the day, including net metering and battery storage.
Q:Which one is better solar or electric?
A:The solar power system is less space-consuming and can be installed on the rooftops of houses, buildings, businesses. Solar power is usually the best choice for urban and suburban areas.
