Product Description:
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.
Specification of Solar Polycrystalline
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.
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.
- Q: Hi. I need to build a solar panel for a project. it should be able to light a 60 watt light bulb. also, it should be about 3x3 ft if it is 50% efficient. if anyone knows any websites or can help me, please answer! thanks.
- Making your own photovoltaic (solar electric) panel is a nontrivial matter if you want to get 60 watts out of it. If this is a science fair project, there are some possible paths that I'd suggest: ) Make your own cupric oxide panel. With just one square foot, you can harvest perhaps 0.5 mW in bright sun - enough to power a solar calculator; -or- 2) Buy a panel to light your 60 watt bulb. You could probably get away with a panel that is 6 square feet, but would use a car headlight as the lamp. If you wanted to light a regular household bulb, you would need electronics to step up the voltage, and you would lose a sizeable fraction of the energy just in the conversion. -or- 3) Buy broken solar cell pieces, or individual solar cells, and solder them together into your own panel. This is a LOT of trouble, and is a finicky process to get working and keep working. And it may not end up being cheaper than buying a ready-made panel. But you can claim that you made it! By the way, crystalline silicon panels are in the ballpark of 5% efficient, and a 3' x 3' one would produce in the neighborhood of 20 watts.
- Q: this solar panel i saw was for 500 dollars(i get a 25% discount)and i was curious will they produce electricity? or just heat?what do they do?is it a good investment?here is a link to the one i would like, no reviews but it looks new to the site.
- This is a photovoltaic panel...it produces electricity from incident solar radiation. Solar thermal panels produce heat, and they are usually assists for hot water heating systems. Solar thermal panels have piping in them instead of semiconductor cells like photovoltaics do.
- Q: how much do you think it would cost for installation?i heard that solar panels can store electricity and any excess electricity gets sold back to the electric company. how much money can a home owner make from doing this?do you think solar panels are worth it?
- Almost sure that you will discover everything related solar power at www.okorder .
- Q: Can solar panels be installed on a garage or carport?
- Yes, solar panels can be installed on a garage or carport. In fact, these structures often provide ideal locations for solar panel installations, as they typically have sufficient space and exposure to sunlight. Adding solar panels to a garage or carport can help generate clean energy, reduce electricity bills, and provide shade or shelter for vehicles or outdoor activities.
- Q: If a solar panel has a power rate of 80 Watts and efficiency of lets say 30%. Does that mean the maximum power this solar panel can generate is (30/00)*80=54 Watts or its just 80 Watts?
- If it says STC or Standard Test Conditions on the nameplate or documentation, then that means 80 watts under bright sun at an unrealistically cool temperature. It is rare to see that power in real life, except when the perfect storm of conditions come together. There is also a PTC rating for some panels, which is more realistic. If the panel does not say STC or PTC, the manufacturer is free to make up whatever test they feel like, which generally leads to ridiculously overstated power. As for efficiency, for residential panels, that's generally only of academic interest. A 80-watt panel is 80 watts, regardless of the efficiency. A more efficient panel will take up slightly less space, but most people are more interested in the total price, since roof space is generally not an issue.
- Q: our school spends around $0,000 dollars on energy.we want to know how much money would installing solar panels on the roof save our school.
- Your school spend $0,000 per month or per year?? Photovoltaic (Solar Panel) panels have a really large initial capital investment. If you live in a location (e.g. West Coast Desert, SoCal) where there are many sunny days so you might be able to break even quicker. Also note ,there are state and federal grants that can help ease the capital cost. Energy demand keeps going up so expect our current rates to double. People who have alternative forms like wind and solar will have the advantage when this time comes. Just think of when the US had it's oil crisis in summer of 2008, people with small efficient vehicles such as Prius's didn't feel the price increase like the people who bought cheaper large SUV's.
- Q: Can solar panels be installed on churches or religious buildings?
- Yes, solar panels can be installed on churches or religious buildings. In fact, many religious institutions have embraced solar energy as a sustainable and cost-effective solution to reduce their carbon footprint and lower energy bills. Installing solar panels on churches not only aligns with their commitment to environmental stewardship but also allows them to set an example for their community by promoting clean energy and sustainability.
- Q: I'm going to pitch an idead to my school about switching to Solar Energy. What are positive and negative effects of the solar panels?Also what is the cost for installing them into a highschool?How much would the electricity bill decline afterwards?
- If you hope to get a solar panel that can run appliances and air conditioning.. then you are not even close to being realistic about what solar panels can do. If you really want to install a solar panel array on your home, then you need to talk to a company in your area that designes and installes them because every installation is different.. so you won't get an answer here on Yahoo. You can expect to spend $20,000 to $30,000 that will provide enough solar power for the average home.
- Q: How do solar panels affect the roof warranty?
- Solar panels generally do not void a roof warranty, but they may have some impact on it. The installation process of solar panels involves drilling holes in the roof, which can potentially cause leaks if not done properly. Therefore, it is important to hire a reputable installer who is experienced in working with solar panels and understands the intricacies of a roof. Some roofing manufacturers may require specific mounting systems to be used, and failure to comply with these requirements may void the warranty. It is advisable to consult with both the solar installer and the roofing manufacturer to understand any potential impact on the roof warranty before installing solar panels.
- Q: I have this question for extracredit and I dont get it?How many 2V,2W PV panels would be required to supply a load that requires a 48-volt supply that can push at least 2.8 amps of current, if you assume each panel puts out A at 2 V? And how are the panels configured to supply the power requirements of the load?
- i agree with Liz but have a diffrent point i think u have not calculated for the roof mounted solar panels i am giving youy a bsic understanding hope that will help you Roof Mounted solar power systems consist of solar panels held in place by racks or frames which are attached to roof based mounting supports. Roof based mounting supports include: Pole mounts which are attached directly to the roof structure and may use additional rails for attaching the panel racking or frames. Ballasted footing mounts such as concrete or steel bases that use weight to secure the panel system in position and do not require through penetration. This mounting method allows for decommisison or relocation of solar panel systems with no impact on the roof structure.
