156*156mm Poly Cell Poly Panel China High Quality Module Price from China Factory

 

product description

 

Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or solar photovoltaic module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. Solar cells are usually connected in series in modules, creating an additive voltage. Connecting cells in parallel yields a higher current; however, problems such as shadow effects can shut down the weaker (less illuminated) parallel string (a number of series connected cells) causing substantial power loss and possible damage because of the reverse bias applied to the shadowed cells by their illuminated partners. Strings of series cells are usually handled independently and not connected in parallel, though (as of 2014) individual power boxes are often supplied for each module, and are connected in parallel. Although modules can be interconnected to create an array with the desired peak DC voltage and loading current capacity, using independent MPPTs (maximum power point trackers) is preferable. Otherwise, shunt diodes can reduce shadowing power loss in arrays with series/parallel connected cells.

Q:time till a solar panel pays itself off?
lots of info about solar panels, perhaps you'll find answer to your question renewableenergyarticles.blogspot....
Q:Solar panel setup?
The solar panel wires go to the charge controller. The charge controller wires go to the battery. You can also run wires from battery to a load ONLY IF it is DC load. If any AC loads, then you need a inverter to change dc to ac.
Q:environmental benefit of solar panels?
Hi there, as a great starting point take a look here okorder Should give you most of what you require
Q:I am doing a Solar Panel DIY?
Sounds like fun. A -watt panel doesn't need a charge controller, though. In fact, it may take more than watt to power the charge controller. With a low-wattage panel, you can just connect the panel directly to the battery. A 7 amp-hour gel cell (the kind used in burglar alarms) would be good for this purpose. The panel is too small to charge a car battery. The gel cell should power that inverter, but only for a few minutes. If you want to be more impressive, look for a low power, 2-volt device. An iPod plus a 2-volt car adapter would be an example.
Q:Solar panel for laptop?
laptop don't get enough power.
Q:can i join multiple solar panels?
It sounds like you intend to put them all in parallel, since you mention blocking diodes. If the panels are all roughly the same voltage, that should work. Mismatched panels will also work, but there may be little to no contribution from the lowest voltage ones if they are severely mismatched.
Q:how can i build my own, cheap, solar panels at home?
The idea behind building your own was to get defective and broken solar cells from the manufacturer, preferably for free though many now charge for them. These are cells that are either cosmetically blemished, cracked or otherwise broken during manufacturing and transportation. As each cell fragment could have very different voltage and current characteristics, you have to manually measure the voltage and current characteristics, sort them and then wire them in parallel or in serial to achieve the desired voltage and current characteristics for the panel. Wiring in parallel increases the current while wiring in series increases the voltage, the current capacity of cells in series will be that of the lowest current capacity cell in that series hence you need to match fragments up to wire in parallel till you have enough current capacity to participate as a cell in the series. Cell fragments can only be wired in parallel if they have the same voltage output. It's painstaking work and it's difficult to place all the irregular shaped cells onto the solar panel in a layout that efficiently uses the space so your solar panels will likely be much larger than commercial ones. You could augment them with Fresnel lenses since the cells don't occupy as much of the available surface area hence focusing the light onto the cells rather than the board will help with efficiency. Practice your soldering skills cause you don't want to have to go back in to figure out where that cold solder joint is. If you're real lucky you can get a supply of blemished cells but the cheapest ones are the broken cells.
Q:Could solar panels contribute to global warming?
As far as any albedo effects from solar panels, the entire USA only occupies a little over 2% of the worlds surface, if you painted the USA black, it would have a minimal effect on globally averaged temperatures. The mining of the resources alone required to cover the entire USA with solar panels would devastate the planets ecosystem. . .

Q:Questions about charging batteries via solar panel...?
Charging voltage = 2*3.8 = 27.6V Current regulated to AH rating divided by 0 Charging time = 0 hours
