First of all, the price of a solar folding package and a solar panel is about the same. The first thing you need to know is what type of solar folding bag you're making, whether it's a sewn bag or an all-in-one laminated bag. As the name suggests, the solar panels inside the bag are separated from the cloth. The solar panels are made first and then sewn together with the fabric. An integrated laminated solar folding bag is a sheet of solar cells and cloth that is laminated in a laminator. The waterproof performance of the integrated lamination will be better than that of the sewing bag. The integrated lamination generally does not carry the storage bag, and the price will be higher than that of the sewing bag.
The second thing to choose is the battery you use inside the solar folding bag, single crystal, polycrystal or Sunpower, 4mm twin solar cable. In terms of conversion efficiency, Sunpower> single crystal > polycrystal. In terms of price, Sunpower> single crystal > polycrystal. Then you have to consider the size of the power of the solar folding bag. The greater the power, the higher the price of the solar folding bag will naturally be. Choose how much power. This is according to your choice of charging equipment to determine if you charge the phone, then you choose a 10-20W folding bag fully enough, if you use a 100 W solar folding bag that is a bit of waste. So if you are charging 500W of energy storage, then 100 W of solar folding bag is OK, 10 W of folding bag is not enough.
There is also related to the accessories brought by the solar folding bag, whether it is necessary to bring a handle, the integrated lamination belt handle should consider the way of solar folding bag out, its installation will be more complex, because once the design of lamination can not be changed. Just sew the bag according to the solar panel, and then sew it. Do you need a storage bag? Is it directly outside the folding bag holder or a whole storage bag? Take ECOFLOW for example, its storage bag can be stored, and can be used as a bracket (it is an integrated lamination, as said before, in the integrated lamination bag itself to do the storage bag will be time-consuming, naturally cost money). This is a relatively high point. It is wire finally, wire appears to consider MC4 to go out or other, whether need to match other interface. It's a matter of what you charge, what you store. If you store for Jackery, it's Andersion.
After considering these, the demand to tell the business will naturally give you a quote. Or you can directly go to a treasure search, look at the details page, will be written, basic will meet daily needs. If you are a business, then you can find the manufacturer to tell you the needs, can be customized. Generally, this will have a minimum order quantity demand.
