Details Of Polycrystalline Solar Panel (25W—310W)

CNBM Solar photovoltaic (PV)module is designed for large electrical power requirements.

It is the optimal choice for both on-grid and off-grid power systems.

CNBM Solar panel offers high performance of power per square foot of solar array.

Poly- or multicrystalline silicon(poly-Si or mc-Si): made from cast square ingots — large blocks of molten silicon carefully cooled and solidified.

Poly-Si cells are less expensive to produce than single crystal silicon cells, but are less efficient.

US DOE data shows that there were a higher number of multicrystalline sales than monocrystalline silicon sales.

 

Main Features of Polycrystalline Solar Panel (25W—310W)

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

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

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

IV  AI frame: Without screw, corner connection. 6 holes on the frame can be installed easily.

V Junction box: Multi function junction box with water proof.

VI Long lifetime: ≥25 years; Less power decrease.

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

Q:Air conditioner 25 volt 5 amps: how many solar panels and batteries to run 24/7?
You are probably going to need about 60 panles and 60 batteries....you will also need a very good power inverter. Also consider the power it takes to invert 2 volt DC battery power in to 20 volts AC power required for an air conditioner. You might consider also trying to find a 2 or a 24 volt unit cooler. You would be better off buying a generator. Solar panels and batteries are not going to run an air conditioner for long if at all.....it might be cheaper to have the power company run the power.
Q:What ever happened to solar powered panels?
they still make them,i have them on my camper to charge the batteries, they are not cheap, however. you can get them at r.v. supply stores. in fact the ones they make now, are quite efficient, many people in the countryside use them for their homes, i dont know why the development for cars is so slow, though.
Q:Why should people use solar panels more for houses?
Right now, the U.S. government and some state governments (like California) are offering subsidies on solar panels for businesses and houses. With these subsidies, anyone infesting in solar power today will have their investment returned in less than 0 years. This means that with these subsidies, solar panels are basically paying for themselves; they're free. In addition, excess power generated on solar panels can be added to the local power grid and, if you're lucky and can set it up with your local power distributor, the power company will pay you for the power you generate. This are just financial reasons. Their is also the reduction of power generated by fossil fuels when using solar power which mitigates climate change.
Q:Need Help, 2v Solar Panel for Emergency?
You don't have much power to work with there. You could hook it up to a car battery to give it a sloooooow trickle charge. One amp will take like 60 hours of sunlight to completely charge a car battery. You'll be able to power small radios, ones that need nine to twelve volts or so. Just position the panel a bit away from the direct to the sun angle for your 9-volt radios, right at the sun for 2-volt radios. I would not try to power any AC adapters. You'd have to buy a DC to AC inverter, a very small one, and the inverter would steal about half the energy.
Q:Pls is it ok to connect a 0watt and 20watt solar panel together into a charge controller port?
Tobi, generally yes, solar panels are like beer, all the europeans get along fine, you can put two Belgiums in the same room as one German and three Englishman. As long as the panels have roughly the same open circuit voltage, usually around 8 volts, then go for it. If you're not sure about this, or the panels voltage disagrees dramatically, then they can still work through the same charge controller, the only other thing you need is a bypass diode in the junction box on the back of each panel. Most modern panels come with these already installed. They are simply electrical check valves, allowing current flow in one direction but not the other. The reason these matter is when the sun is first coming up, the higher voltage panel can force its power backwards through the lower voltage panel, at least until they both reach a voltage higher than the charge controller is set at. This is not a desirable thing to have happen, the 20 watt panel, if its voltage is higher, can damage the 0 watt panel without these diodes if the 20 watt has a much higher open circuit voltage, or Vmax. Look on the back of the panel for these ratings. The only other concern is maximum current. A charge controller has a maximum current it can handle, they are generally model numbered this way, a Xantrex C-60 for example has a 60 amp rating. Add up the Imax numbers on the back of all your panels, this is the maximum amperage the panel should put out. As long as it is not above 80% of your charger controllers maximum amperage, your good. Take care, Rudydoo
Q:Solar panels........................?
Solar panels are one of today's best investments! With a lifespan of 25 to 30 years minimum, and a payback period of 0 year or less, the economics are a no-brainer. There are often state loan programs giving you low interest or no interest for a length of time. There are also tax credits and rebates that take care of a lot of the up front money. Calculate for yourself what you will pay to your utility over the next 30 years. Then see how the cost of a solar electric system compares. My company has helped scores of homeowners and business owners claim Independence and take control of their energy costs for the next few decades. Contact us to have a site evaluation and payback analysis for your particular situation.
Q:What kind of batteries to use for a solar panel?
If you will be storing them outdoors, you can use auto batteries. Indoors, use sealed marine batteries. Number and size depends on your needs. You will need a charge controller between the solar panels and the batteries to get the maximum power out of the array and to avoid damage to the batteries. And you will need an inverter to convert the 2 or 24 volts to 20 or 240 VAC. One large lead acid battery will supply about 000 watt-hours of energy, enough for 200 watts for 5 hours. You have to look at your loads and decide on how many batteries you need. Frequently it is cheaper to buy new appliances that use less power, as that power difference can save a lot of money in batteries, inverter, charge controller and solar panels. But it sounds like a few thousand watt-hours will be enough, or 2 large batteries. The real limiting factor is how much money you want to spend for the solar panels themselves. .
Q:Is there any way I can get solar panels with my restrictions?
The big problem is that you cannot force the homeowners association to do anything. I live in a condo with a HOA. We have outside parking spaces. The goonies won't let people run electric lines to parking spaces to charge electric cars. Several years ago, residents had to sue the HOA in court because they would not allow satellite dishes on buildings. The HOA lost. You don't have money to pay an attorney so you are out of luck.
Q:Solar Panel: Watts, Amps, Volts? mA?
mA means milliamps, i.e. 200 mA is the same thing as .2 amps. Amps refers to current and is the unit of measure for electrical current... Anyway, my point is, you are NOT going to be running ANY small appliance with a single solar cell. You might be able to run a small device that would normally run with a battery, but that is about all.
