FAQ

We have organized several common questions for our clients,may help you sincerely:

1). What’s price per watt?

A: It’s depends on the quantity, delivery date and payment terms of the order. We can talk further about the detail price issue. Our products is high quality with lower price level.

2). Can you tell me the parameter of your solar panels?

We have different series of cells with different power output, both from c-si to a-si. Please take our specification sheet for your reference.

3). How do you pack your products?

We have rich experience on how to pack the panels to make sure the safety on shipment when it arrives at the destination.

4). How long can we receive the product after purchase?

In the purchase of product within three working days, We will arrange the factory delivery as soon as possible. The perfect time of receiving is related to the state and position of customers. Commonly 7 to 10 working days can be served.

Q:what is the best solar panels to use on my new house(tube or flat)?

Q:Power Point on solar panels?
Refuse to do the work on the grounds that it is not good for your school to switch. If the teacher tries to give you an F, escalate the problem to the principle and then the local news agency. Teachers are not allowed to force brainwashing.
Q:are flexible solar panels possible?

Q:how efficient are flexible solar panels?
Up to now, it has very poor efficiency, about 5% to 23%.
Q:What is a good solar panel to buy?

Q:DIY kit for solar panel?
Have okorder.com . This can immediately instruct each and every one!
Q:Joule Thief vs Solar Panel?
Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
Q:Im looking at getting solar panels.
Most major cities have construction signs and other public things powered by solar panels. We have parking meter stands, USGS meters, street lights, etc. when these lose efficiency, they need to be replaced. They still work at about 60 percent efficiency. Learn who services these items and ask how to get them at a reduced rate or even for free. Be personable and nice and go to the source physically, not via e-mail. You can get a solar panel to run just about anything
Q:Solar panel, Home office and Tax write off?
The solar panels are a capital improvement. You can deduct 5% of the depreciable portion of the property as part of the home office deduction. You'd have to depreciate the solar on the same 39 year straight line schedule as the house itself. (The land value is never depreciated so you'll have to break that out separately.) Since this is business use of real estate, the depreciation is over 39 years, not the 27.5 years for residential rental real estate. That crunches out to a whopping $38 deduction per year for the depreciation on the solar panels. ($0,000 x .5) / 39 = $38.46 which rounds down to $38. If you're in a 25% tax bracket, that will save you a whopping $0 in taxes. Keep in mind that when you sell the home, the depreciation allowed or allowable will be subject to recapture. That is taxable income subject to a maximum tax rate of 28% even if you can exclude the gain on the sale under Section 2. For that reason you might wish to consider the safe harbor deduction new for tax year 203. You may deduct a flat $5 per square foot up to 300 square feet for a maximum deduction of $,500. That won't trigger the depreciation recapture (for the years that you use it, you can switch off year for year if you wish) and may reduce the likelihood of an audit as well.
