1.Structure of Solar Module Description

Solar panel refers either to a solar hot water panel, a common type of a solar thermal collector, or to one or more solar photovoltaics (PV) modules, electrically connected and mounted on a supporting structure.

A PV module is a packaged, connected assembly of typically 6×10 solar cells. Solar PV panels constitute the solar array of a photovoltaic systemthat generates and supplies solar electricity in commercial and residential applications. Each module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16% efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency. A single solar module can produce only a limited amount of power; most installations contain multiple modules. A photovoltaic system typically includes a panel or an array of solar modules, an inverter, and sometimes a battery and/or solar tracker and interconnection wiring.

2.Main Features of the Solar Module

 1).High conversion efficiencies resulting in superior power output performance.

 3).Optimized design for ease of soldering and lamination

 4).Long-term stability,reliability and performance

Specification of  Solar Polycrystalline(270W-290W)

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.

GENERAL SAFETY

1.    Consult local codes and other applicable laws concerning required permits on regulations concerning installation and inspection requirements.

2.    Before installation a PV module, contact appropriate authorities to determine permit, installation and inspection requirements that should be followed.

3.    Install PV modules and ground frames in accordance with applicable rules and regulations

4.    PV modules should be installed and maintained by qualified personnel. Only installer/service personnel should have access to the PV module installation site.

5.    No matter where the PV modules are installed, either roof mounted construction or any other type of structures above the ground, appropriate safety practices should be followed and required safety equipment should be used in order to avoid possible safety hazards. Note that the installation of some PV modules on roofs may require the addition of fireproofing, depending on local building / fire codes.

6.    Please use PV modules with same cell size within series.

Q:What ever happened to solar powered panels?
I saw a commercial the other night for a fan you hook onto the top of your car window, and it's solar-powered. (supposedly cools off your car while gone...as opposed to just cracking the windows some). Also, I've seen traffic lights and emergency beacons on the highway powered by solar panels.
Q:How much power does a solar panel generate?
That site tells you somewhat about the cost of solar panels and their MAXIMUM output. Now some who have these panels claim output, in daily terms, 8 times as great as maximum output, which says they are counting on 8 hours of effective sunlight. In California Desert that is sound. You will discover that Ontario Power grid is planning for 3 hours to 4 hours of maximum output . Based on that 3 to 4 hours of maximum output, it would take close to 20 years to recover your cost at the price Ontario pays for solar power. The deal locks you in so that you can not get more money as electricity prices go up, and do not lose if electricity prices go down over that 20 years.
Q:what is the best solar panels to buy?
It Can produce enough energy to run fans and yes keep the house cool. And if you also want to make one try it out. Good luck and save energy
Q:Can you lease your property for solar panels?
Hi, In the UK solar companies will fit them for nothing. The company gets the government allowance (called feed in tarrif FIT) and you get the benefit of the reduction in your power bills. The solar company make better money than the householder,BUT if the householder is in most of the day it could be most beneficial if the energy is used while the panels are generating, this means the householder is not paying for the power from the grid. If the householder works normally from 9 to 5 then there is less advantage in terms of getting free power from the panels. Best Wishes.
Q:Solarcity free solar panels?

Q:How much does a race car that uses solar panel cost?
thats an oxymoron/race car with solar power/forget it/by the by if they start to really harvest the available sources for power the retail price of gas will be 25cents a gallon/
Q:How many LED's can power a solar panel?

Q:Im a bit confused about what a solar panel is?
A two KW system would be made up of a number of solar panels. Panels used in residential and commercial systems usually run in the range 50 watts to about 200 watts. There is a HUGE amount of information available on the internet about solar panels and all the components of solar electric systems. All you have to do is search on the internet under solar panel. It's very safe and easy. So just do it.
Q:Connecting solar panel help?
No. You can only hook them up as one or the other. Attempting to do both would simply short circuit the panels and you'd get no output at all. Your panels should produce an open circuit voltage in full sun that is almost twice the voltage of the battery you want to charge (it's because solar panels produce the most power at their maximum power point, which is usually about 60% of the open circuit voltage). If a parallel connection does that, then use it, otherwise you'll need to use series. You didn't say what the capacity and voltage of the panels or the size of the battery was. It's quite possible you don't have enough panel - you need panels that will put 5% (at least) of the ampere hours capacity of the battery in as current. For example, if you have a 00 amp-hour battery, you'll need enough panel to put 5 amps in at the voltage of the battery. DK
Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
OK your math on the solar panel looks correct, but you are missing some critical information. What is the load on your batteries and for how long is this load being applied. Calculate the amp-hour load to see if your solar panel can recharge your batteries with the amount of sun light available. A safe engineering standard is to have twice as much capability as required. If you have a 200 amp load for 7.5 minutes, this would be a 25 amp-hour discharge and will take your solar panel over 7 hours to recharge your batteries. Your solar panel can easily charge the batteries up to full capacity with out any load on the batteries, if the batteries are 50% discharged, this will take about 32 hours. CAUTION! I am assuming that you are hooking the batteries up in a parallel connection, that will give you over 200 amps of current. You should charge each battery up to full charge before you connect them together, if they are not at the same exact voltage when you connect them together, they will self adjust so that each battery is at the same voltage level, at 55 amps this could be a very large spark. Each cell, there are six (6) cells in a 2 volt battery, should be at 2.7 to 2.2 volts DC per cell at full charge. Make sure your battery has a voltage 3.02 to 3.26 volts open circuit or no load. This should be full charge if your batteries do not have this voltage level, say one battery is at 0 volts DC, it could have a dead or shorted cell. DO NOT use this battery until you can get it to hold a 3.02 to 3.26 volt DC level.
