Product Description:

1.Structure of Solar Module Description

CNBM Solar's photovoltaic module is designed for designed for large electrical power requirement. It is the optimal choice for both on-grid and off-grid power systems. CNBM Solar offers high performance of power per square foot of solar array.

 

2.Main Features of the Solar Module

Solar Cell: High efficency crystalline solar cell. Even if under the weak light, the solar module can produce maximum power output.

Tempered glass: Anti-reflecting coating and high transmission rate glass increase the power output and mechanical strength of solar module.

EVA and TPT: Using high quality EVA and TPT to prevent destroying and water.

Strong aluminum frames to strengthen the load hold and to stand against high wind.

Junction box: Multi function junction box with water proof.

Long lifetime:  ≥25 years; Less power decrease.

Good performance of preventing from atrocious weather such as wind and hails.

Resisting moisture and etching effectively, not effected by geology.

The certificate issued by international authority: UL, TUV, IEC, VDE, CE.

Q:Is using a thick cardboard backing for a solar panel ok?
In commercial panels some sort of polymer is often used for backing. With a 2V panel there are 36 cells, which means they can still output about 4V for charging a 2V battery even when hot. The voltage reduces about 2.2mV per degree C per cell. Commercial panels are meant to work up to about 60 degrees C, which is quite normal in the sun. I have found just lying them on the grass the air circulation is reduced, and they get too hot to charge a 2V battery. This means the backing should have good thermal conductivity while being an electrical insulator, as well as mechanical strength. The cells are often encapsulated in a thermosetting plastic first, then laid face down so a liquid polymer can be poured as backing.. I have removed commercial panels from their frames and re-packaged them to work in a very wet environment. I suppose cardboard would work, but it is unlikely to have good cooling so the expected voltage would be lower. As you intend to only operate indoors I suppose it is unlikely you have full sun most of the time anyway, so there could be less heating and less output current accordingly. I think the cardboard is only useful for a short time, and is not strong enough. Temperature wise it is marginal. The link below uses plywood for the backing. The backing is supposed to provide strength too. A sheet of some sort of plastic or laminate (including melamine laminate as in kitchen bench tops) comes to mind too. The cells are supposed to be bonded to the backing for better thermal conductivity. Use silicon RTV to stick cells to the backing, very thinly.
Q:260 watt solar panels on an rv?
It depends on the power you need. There should be a controller between the battery and the solar pv panels.
Q:solar pannels capacity?
You can find a lot on the Internet about how solar panels work. See the links below. I'm not sure how you define capacity. Solar panels are made up of many solar cells. Each cell is capable of generating a low DC voltage while delivering a small current, Several cells are connected in series, making strings to develop the required voltage. Then many of these strings are connected in parallel, so the panel can deliver a usable current. Then the panels are connected in series and/or parallel to deliver a usable voltage and current. My panels are rated at 24 volts. 20 panels are connected in series to develop 480 volts. This is sent to an inverter, which converts the 480 volts DC to 20 volts AC
Q:Benefits of Solar Panels?
Would that be Portland General Electric? I used to live in Beaverton. I think technology has not progressed enough for solar electric panels to be a good deal in that area. Too many clouds. If you were over in Eastern Oregon, that would be clearer. If you meant Pacific Gas and Electric, that's another story. It's a good deal in most places in California. PGE only gives a trivial rebate on panels now, but that's ok.
Q:Info about solar panels?
Good question, but I don't think big oil likes solar panels.
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:Do solar panels keep a structure cooler?
The type depends upon what you want the solar panels to do. Generate electricity ? Heat gain? Makes a big difference. You should probably get a contractor who specialises in solar panels out to at least start your education on this subject or you could throw a lot of money away on something you don't really need or want.
Q:How much power does the solar panel produce?
Area is 4' * 2' * (0.3048m/ft)^2 = 0.743m^2. Incoming solar (assuming optimally oriented panel) averages about kW/m^2, so 743W max gross. 4% efficiency yields 300W. Most panels are about 0% - 5% efficient, which is about W. In either case, figure about /2 the theoretical efficiency for about 2 hrs per day. so, you can run something from 50 to 50W about 2hrs per day. Too small for any appliance except maybe a laptop or light bulb. Panels typically make about 2V, not enough to run household stuff anyway. Normally panels are used to charge batteries, then an inverter takes power from the battery to run your appliances. Good luck!
Q:How effective are solar panels?
it depends on the size of the panel and if it is installed in an optimal location. there are many 00W panels commercially available and they can be ganged for a number of different output configurations.
Q:how efficient are flexible solar panels?
One I got about 3 years ago is about 50% as efficient as a glass panel I got about 0 years ago. Not exactly a scientific study, I know.
