FAQ
1. Q: Do you have your own factory?
A: Yes, we have. Our factory located in Jiangsu province.
2. Q: How can I visit your factory?
A: Before you take off from your country, please let us know. We will show you the way, or arrange time to pick you up if possible.
3. Q: Do you provide free sample?
A: Usually we do not offer free sample
4. Q: Could you print our company LOGO on the nameplate and package?
A: Yes, we can do that.
- Q: Can solar panels be installed on a south-facing wall?
- Yes, solar panels can be installed on a south-facing wall. In fact, a south-facing wall is often the most ideal location for solar panel installation as it receives the most direct sunlight throughout the day, maximizing energy production.
- Q: can this amount of solar charge these batteries.
- 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: I have an inverter and a battery 20 Amperes.Daily sun shine approx. 7 Hours.Do I need to buy anything or should I connect the solar panel to the Battery direct?
- connect the solar panel to the Battery direct during the day time that's how it works in ALL situations !
- Q: The battery is 9ah and the solar panel is 20w
- You need a switch mode voltage converter, made to input 2 to 20 volts, and output around 7 volts. Some cell phone chargers can do that, or be modified for that voltage. Option B is to get another battery and use the system at 2V, and regulate that to 6 or 5 volts for charging (you can directly use your car charger), with switch mode regulators. I would find that system to be more flexible. Getting an 8Ah would leave extra capacity. BTW, for a 9AH battery, 20W is kid of big. I have a 36Ah battery and a 20W panel, and that is good for it.
- Q: Is there a material that is capable of absorbing enough UV radiation to make it worth using as a flexible solar cell?Not flexible as in aluminum, but a material such as plastic (polycarbonate).

- Q: I was thinking of having some installed on our rooftop and was wondering if it would be worth the cost? The house is located in Sac, Cali. The panels would face the sun 2 months out of the year and in the summer roughly 4 hours of straight sun.
- Solar is too expensive system. It is relatively new. Everything new is top dollar. When the market gets flooded the cost will dramatically go down as everything like cell phones, computers etc.
- Q: Can solar panels be installed in urban areas?
- Yes, solar panels can be installed in urban areas. In fact, urban areas provide great opportunities for solar panel installations due to the abundance of rooftop space and potential to generate clean energy in densely populated areas.
- Q: Has anyone had any experience building their own solar panels for home use? I have seen on the news lately that people are utilizing solar panels to power their hot water heaters to save on their power bill.
- Hey David, yes, we have built plenty of them. If you are into the do it yourself world, the easiest type to build is the Batch Preheater type. What you need is an old water heater, something small, like an under counter model, 0 to 30 gallons in size. It has to be one that hasn't rusted out yet and started leaking. We stopped at a local plumbing place in town, they are always throwing out units they have removed from homes because the new owner wants a larger unit, or gas versus electric, and so on. He sold us a pretty recent model for $0. Take the water heater home, and strip off the outer metal housing and all the insualtion so all you have left is the tank. Clean it up, and paint it with black paint. Now build a wood enclosure, something the size of a dog house that your tank will fit inside of. Use a glass panel for one side of the roof. What works best is an old window pane someone is throwing out that is about the right size, then build your dog house to fit it. When it's done, put some styrofoam insulation panels around the back and side walls to keep the heat in when the sun shines on it, then mount your tank inside. Put your dog house someplace in the sun, run the cold water that normally feeds into your water heater into the tank (in the cold inlet side), then run a pipe from the outlet of the tank to your regular water heater. We have one just like this installed in the northern midwest, it works great about 7 months of the year. Usually in the summer if it's about 75 degrees outside, the water comes into the house at around 00 degrees, then the regular water heater only needs to add another 25 degrees to the water to finish it off. Since the water starts out at about 56 degrees, the solar preheater ends up doing about 65% of the work. In the winter, we simply drain the tank and lines to and from it, and route the cold water directly to the regular water heater. There are some designs on line, try googling, Batch Water Preheater. Take care, Rudydoo
- Q: Can solar panels be used in agriculture?
- Yes, solar panels can be used in agriculture. They can provide clean and renewable energy to power various agricultural processes such as irrigation systems, livestock operations, and crop drying. Additionally, solar panels can be installed on farm buildings or in open fields, helping farmers reduce their reliance on traditional energy sources and lower their carbon footprint.
- Q: Can solar panels be installed on a community center or social gathering place?
- Yes, solar panels can be installed on a community center or social gathering place. Solar panels are versatile and can be installed on various types of buildings, including community centers, to harness solar energy and reduce dependence on traditional energy sources. This can help make the community center more sustainable, reduce its carbon footprint, and potentially save on energy costs.
