Solar Polycrystalline Series Panels

Introduction of Solar Polycrystalline Series Panels

CNBM Solar photovoltaic (PV) Panel 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. Monocrystalline silicon(c-Si): often made using the Czochralski process. Single-crystal wafer cells tend to be expensive, and because they are cut from cylindrical ingots, do not completely cover a square solar cell module without a substantial waste of refined silicon. Hence most c-Si panels have uncovered gaps at the four corners of the cells.

Q:how many solar panels?
dozens at a huge cost which only run in sunlight so not ideal for running lights, solar panels are just not economical or reliable, probably around $5000?
Q:Solar Panels!!???!!!?
Solar Panels are collections of solar cells. These panels basically collect the incoming sun's electromagnetic radiation and convert it into electrical energy. A solar cell is any device that directly converts the energy in light into electrical energy through the process of photovoltaics. The development of solar cell technology begins with the 839 research of French physicist Antoine-César Becquerel. Becquerel observed the photovoltaic effect while experimenting with a solid electrode in an electrolyte solution when he saw a voltage develop when light fell upon the electrode.
Q:Solar panel setup?
I hope you have some instructions. You need safety switches and fuses in the circuit. What voltage/currents are you running? Don't burn the house down or get electrocuted please. DC can be very dangerous.
Q:It's all about Solar Panels?
here's lot of articles about the questions you just asked about solar panels, enjoy renewableenergyarticles.blogspot....
Q:How to select solar panel for this application?
First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
Q:SunPower Solar Panels?
You should get the highest efficiency at the lowest price. Typically, the Sunpower brand panels have the industry best 23% efficiency depending on the model. You have to look at the specification very closely and if you don't see it, ask. There are two types of solar cells Polycrystalline and Monocrystalline. Polycrystalline cells are inferior to Monocrystalline. You will also see that different kinds of panels have different output voltages.Since you will be wiring your panels together and connecting them to either a power inverter or a charge controller (if you have battery backup), you need to make sure the panels and controller work together for maximum efficiency. Be very careful when engaging an installer especially when they are trying to sell you the equipment too. Mostly, these are not engineers and you will end up with whatever they have in stock without regard for the most optimal design.
Q:Making a Charger out of small solar panels?
The first item is whether the psp charger output is ac or dc. IF, AC then you are stuck as the panels put out DC. (Increasing the voltage enough to cover invertor losses is not practical in this instance!) IF DC, then you need to combine panels to produce 2 Amps, after which it is run through the 3 terminal VOLTAGE regulator to limit the voltage to 5v. That is 8 panels in parallel in 2 groups placed in series = 2amps at 8 volts, then add regulator for 2 amps at 5v. (Parallel increases amps, series increases volts.) Total panels required is 6 panels.
Q:How do you hook up solar panels to your electricity?
nowing what to do with unused renewable electricity is always a dilemma – hooking up to the grid has to be the preferred option. If your residential home is grid tied, i.e. connected the electricity grid as opposed to off-grid and you are using solar panels to generate electricity. Then it makes a lot of sense to hook your solar panels to the grid, because instead of losing the unused electricity or having to maintain a bank of deep cycle batteries, you simply feed it back to the grid. You feed electricity back to the grid via your electric meter which measures the electricity in Kilowatt per hour. This has the effect of reversing your meter which in turn reduces your electricity bills and if you are generating a lot of electricity you could find the utility company owing you money! The Solar Powered System Therefore, your solar powered installation would look like this. The solar panel will connect to an “array disconnect” – you need an array disconnect for system maintenance because it allows you to easily shut off the power. The array disconnect is connected to an “inverter”. The solar panel generates DC power and the electricity from the grid is AC power. Therefore, you need an inverter to convert DC power to AC power. The inverter is connected to an “AC breaker panel”. This is the interface where your solar generated electricity meets the electric meter and allows you to feed electricity back to the grid. Now in most countries and states you are not allowed to tamper with the electric meter so at this point you should contact your local electricity energy supplier and ask them to supply an engineer to hook you up to the grid. If you have anything to add to this article or you have connected your system to the grid – tell us how you did it by writing a comment below.
Q:solar panels and hurricanes?
depends on what light bulbs you have in watts.depends on how many you want on. for the power equation you take P which equals watts x I which equals amps and E which equals volts and you multiply the amps and the volts together to get the watts which the solar panel is generating. for example if you had 7 60 watt light bulbs you would need 420 watts generated. which if you got 50 watt panels each you would need 9 panels. and for what your talking about if you want the stuff to work when the power goes out you are going to need an inverter. not to be confused with a grid ti inverter. and a few batteries i recommend deep cycle batteries that are meant for solar panels. depends on what fan you have.
Q:what kind of rays are used in solar panels?
Electromagnetic...meaning light rays, primarily in the visible spectrum. Ultraviolet and infrared light rays actually degrade most types of solar panels, limiting their useful lifetime. That said, your question is not stated well...so I'm not sure if that's the information you were looking for. Rays are not used in solar panels...rather solar panels are used to collect sunlight and convert it to energy--either directly into heat in the case of passive solar, or into electricity by the use of photovoltaic cells.
