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 cells?
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.
- Q:Solar Panels, anyone?
- You can attempt to install your own solar panels...just do the homework first! I suggest looking at ways to decrease your overall energy consumption first even if installing solar panels. Doing this will save on the amount of panels you need. Have included a reference that may be of use to you.

- Q:i have three 30 watt solar panel and 6 battery cells of 2 volts 550AH. but my batteries are never fully charg?
- Well you are stating the solar panel powers but no mention of their voltage??. Yes, they should do the job. I suspect the lack of blocking diodes may be your problem, assuming you have done the homework. You have 6 battery cells at 2 volts each, that is ...err..2 volts, assuming you have them connected in series. Count the number of cells on the solar panels and maybe we have a starting point. One solar cell is 0.6 v, in this case you would need a minimum of around 30 cells (physically it will probably be 32 to make it 'square'), you need a fair bit of over- sizing in that direction. Solar panels are resistive when not illuminated so must have a blocking diode included to prevent the batteries from discharging into the solar panels at night. Check that each array has a blocking diode included, if not add them. Solar power is pretty useless unless you have loads of sunshine. You seem to have gone through a bit of trouble and expense on this one, so give me some basic facts and I will help you through it. Update 7 Dec If the batteries take 20 hours to fully charge and there are 0 hours of sun each day then the batteries will be fully charged in 2 days. The question was, can the battery be charged, answer is yes, it can. There is no mention of load. If the batteries are not charging there is something wrong.
- Q:Solar Panels heat absorption?
- Solar panels . Are you talking about solar cells or panels ? Solar panels can be either for hot water or electricity but i take it your talking about solar cells that make electricity . Heat has nothing to do with making electricity . In fact when they heat up they give out less so its good to keep them cool . With size they give out equal amounts of volts but less amp the larger the more amp you get. Solar cells work with white light that knock the electrons around that produce electricity . To much such as putting a magnifying glass on them will burn them up but will kick out twice the volt but only for a short amount of time before they burn up . If you can keep them cool with an intense light like that im not sure what they will do but to much heat will destroy them. Edit: Yep you got that right . As far as the desert to make up for the loss of volts because of the heat they just add a few more cells . Say there going for 2 volt it takes 24 cells because each gives you /2 volt but most use around 36 cells if not more . That would give you 8 volt then a regulator regulates the amount going into the battery . Most will put 3 volt into the battery to 4 volt . Freezing temps aren't going to do a thing to them as long as the sun hits them without snow covering them . I build mine with 40 cells getting 20 volt and a bit more on some . That way if its a cloudy day i still get over 3 volt and plenty of amps .
- Q:Need isntructions for solar panel diy?
- Hi Igor, this is a very simplified version of the system I'm implementing in my shed. I used a guide found on an Answers! member's website, you may find what you're looking for there. Check out the sources section.
- Q:How do you hook up solar panels to your electricity?
- Backwoods Home Magazine had a great step by step section in one of their magazines on solar energy, panels, hook-up, etc. You can go to their website, pull that issue up and order the magazine and I believe they offer it on CD. This way you would have a reference guide at the ready when you tackle this project. Godd Luck!
- Q:Choosing right wattage solar panel?
- o work out the wattage correctly, the panel needs to be sized according to how much power you are going to use. (Later on you're going to need a bit of info on each electrical item you need to be solar powered).
- Q:Why won't my solar panels drive a motor?
- The solar cells you have are not providing enough current to operate the motor. There are special low power motors which can operate directly from a solar cell but it sounds like you do not have one of these. Instead you have a common .5V DC hobby motor which requires substantially more current to operate. You can use the original circuit to charge the batteries and use the charged batteries to run the motor. The batteries would be able to supply enough current to operate the motor, but for a limited time. 8 hours of charging might give you less than 5 minutes of motor operation. An LED will draw about 20ma. In a solar light such a small current draw from an LED or two can provide hours of light. A Small DC motor might easily require 300ma to run and over 500ma to start. Running a motor from the same battery at over 5 times the current draw will result in less than /5 of the run time compared to the low current LED. So if an LED operates for 300 minutes the motor would run for less than 20.... The small solar cell size cannot provide enough current to operate the motor directly. Only by slowly charging a battery first would you be able to use the collected and stored Solar energy to operate your motor.
