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.

 2).Outstanding power output even in low light or high temperature conditions

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.

7.    Follow all safety precautions of other components used in the system.

8.    In order to avoid a risk of injury or electrical shock, do not allow anyone to approach the PV module if the person has little knowledge on PV module or on the measures that should be taken when PV modules are damaged.

9.   Do not clean the glass surface with chemicals. Do not let water stay on the glass surface of PV modules for a long time. This creates a risk of white efflorescence(glass disease) which may result in the deterioration of energy generation.

10. Do not clean the glass surface with chemicals. Do not let water stay on the glass surface of PV modules for a long time. This creates a risk of white efflorescence ( glass disease ) which may result in the deterioration of energy generation.

11.  Do not install the PV module horizontally. It may cause dirt or white efflorescence (glass disease) due to water.

12.  Do not cover the water drain holes of the frame. There is a risk of frost damage when the frame is filled with water copulation.

13.  When sliding snow load has to be considered, an appropriate measure has to be taken so that PV module frames on lower edge of PV modules will not be damaged.

14.  Do not expose PV module to sunlight concentrated with mirrors, lenses or similar means.

15.  Turn off inverters and circuit breakers immediately, should a problem occur.

16.  In case the glass surface of a PV module is broken, wear goggles and tape the glass to keep the broken pieces in place.

17.  A defective PV module may generate power ever if it is removed from the system. It may be dangerous to handle the PV module while exposed to sunlight. Place a defective PV module in a carton so PV cells are completely shaded.

18.  In case of series connection , the maximum open circuit voltage must not be greater than the specified maximum system voltage. The voltage is proportional to the number of series. In case of parallel connection, please be sure to take proper measure to block the reverse current flow. The current may easily flow in a reverse direction.


Q: What are the different applications for solar panels for residential use? How many should I purchase if the avg panel produces 80 watts .
Let me start off by saying we (my family and I) live completely, 00% “off of the grid and are completely self sufficient” The house is built utilizing natures natural elements, in the shape of an octagon with 8ft wide arch doors on every wall to catch every angle of wind (typical 4 sided homes have half the chance as one with 8 sides.
Q: I have noticed how solar panels cause a glare. Since I am not around solar panels all the time I relate it to when the sun reflects off another car and right into my eyes. So I always wonder if solar panels effect birds and/or animals due to the glare. If I am wrong and solar panels aren't this bad please tell me.
mynameismud, you are hilarious. I cried i laughed so hard. Holy crap, how old are you?
Q: I have a home in Manchester Tn and we have been slowly remodeling the home. It is about 200 sq ft of living space. Our normal electric bill is about 50 a month. We would like to add some solar panels to the home to help reduce the amount of the bill. How many panels do I need and what would be the cost? I am not trying to go completely of the grid but I would like to start somewhere and maybe over the years be able to add. What is your recommendation for a reasonable cost of under 2 to 3 k??
Ok, well there are also other alternative energy sources, too, besides solar. There is tidal (but you need an ocean :] ), hydroelectric (river, stream, etc.), biomass/biofuels (burning garabage), geothermal (from within the earth, pipes in the earth), wind (windmills, wind, the sun to get wind), and there are others that don't come to mind. Solar energy would cost alot to be installed, and it would take up alot of space, but once installed it pays for itself and uses little to no labor. They all have positives and negatives. All of these are clean and renewable. Here are some sites that my teacher/professor gave us (we just ended alternative energy lesson.) Well I hoped this helped!
Q: This is the cenario. Your yearly energy use comes by mail and it states that the total amount of energy used your household is 7000kWh.Then you make the decision of switching to get solar panels. The question is what area should your solar panel be given that the average annual length of daylight is 2.0.
It is not that simple. There are 3 main types of solar cells. Monocrystalline silicon is the most efficient and produces the smallest solar cells, and therefore the smallest panels. Poly-crystalline (or multi-crystalline) silicon produces the next most efficient type of cells and are a popular choice. Amorphous (or thin-film) silicon uses the least amount of silicon and also produces the least efficient solar cells. This means thin film system take up more area than the other two; an important factor to consider in relation to possible future upgrades; i.e. if you'll have enough space left to do so. The North (in the Southern hemisphere) or South (in the Northern hemisphere) facing roof collects the most energy. So this biases the roof area required. Your energy usage can be changed. Hot water (a major energy user) could be better using direct solar heating with peak demand boosting, either from mains or solar. There are other possibilities, either to reduce demand or to provide energy from other sources. Not all sunshine hours are equal. Hours around midday are far more productive than hours later in the day. This must be factored in.
Q: im aware i dont fully understand. but with what i do. if P = iv, and current changes with voltage, whats the point of changing either. if in any cicumstance, you end up with the same wattage, how does changing either effect a solar setup. (2v panel vs 24v)thanks in advance. explain in laymans if you can.
The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.
Q: I have purchased a 2 volt LED lantern from argos, it comes with a built in 6 volt 4ah sealed acid battery. What I wanted to know is would I be able to charge it using my 6 volt solar panel?
You okorder /... ] But I would suggest you contact . If you email, be prepared to provide more detailed specifications on your 6 volt solar panel and lantern data. You may just have to purchase a RECHARGEABLE 6V 4ah battery from them. Best of wishes.
Q: What are the benefits of solar panel heating?What does it cost for solar panels?any other important facts about it?
Solar okorder /
Q: Can solar panels be installed on multi-story buildings?
Yes, solar panels can be installed on multi-story buildings. In fact, multi-story buildings often provide ample space on rooftops for solar panel installation.
Q: i am trying to get it to work on solar power They are outdoors and we dont feel like running a few hundred feet of power cables. Thanks and best answer will get 0 points.
Only okorder /... Each battery will will need to be enclosed in a box from the weather to preserve it as well as the charge controllers. All this work can be done with success, but will be costly if that's what you want, and want it done right. You have no short cuts around this unless you want to damage your cameras? I still say it would be much easier to run conduit under ground for your power supply to each camera, and it would cost less money and time.
