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

3).Optimized design for ease of soldering and lamination

4).Long-term stability,reliability and performance

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: Ok Im trying to power my room using solar panels and I've figure out that I need about 700 watts to do so, but I really only use my electronics at night. I was wondering if I could buy lets say a 200 watt solar panel and let it charge a battery all day would that work? I live in southern california so I dont have to worry to much about cloudy days. also any suggestions on where to buy a panel, inverter, charge regulator, and battery?: You have to look carefully at your battery choice. If you use lead-acid, use only the sealed type. Then you need to select a battery charger that is tailored to that battery type. If you want to run 700 watts for 6 hours, that is 0kwhrs. A 200 watt panel will take 50 hours to charge that, probably more like 70 to allow for losses. Even is S CA you don't get 70 hours of sun per day. Even for 3 hours of nite use, that still needs 25 hours of sun. So you need much more than a 200 watt panel. Bottom line, you need to calculate your needs much more carefully. PS, 700 watts is very large. Check it. Are you using all that stuff at the same time?

Q: How do solar panels affect the electricity bill?: Solar panels can significantly reduce or even eliminate electricity bills by generating renewable energy from the sun, thereby reducing the reliance on grid-supplied electricity. When solar panels produce more energy than is consumed, excess energy can be fed back into the grid, resulting in credits or reducing future bills through net metering programs.

Q: What is the difference between solar panels and light panels?: The production of silicon requires that the stone be heated to become liquid, and the heating becomes gaseous crystals. During the need to burn a lot of fossil fuels and emissions of toxic gases silicon tetrachloride, this material has a corrosive effect on the skin. After pickling, pulling crystal, cut the side, finished a series of processes, more industrial chain. The cost of the finished product is too high. The energy consumption of making a solar cell requires solar cells to be equal in power generation for several years. The cost recovery period is very long.

Q: Hi, I am starting to get curious about the pros/cons of installing solar panels - has anyone done it and is it worth it?: If okorder and I mention them only because they did a retro fit on my Uncle's house in the Florida Keys and a smaller scale system for my in laws outside of Chicago. Both my Uncle and In Laws really are enjoying the cost savings that they are getting each month from their respective systems, and both said that Sun's initial costs were QUITE low. Be sure to have the blessing of your local building zoning departments before installing the panels as some municipalities take issue with solar panels. Also make sure that your roof is strong enough to withstand the weight of not only the panels, but the bracing. Good Luck.

Q: Can solar panels be leased or financed?: Yes, solar panels can be leased or financed. Many solar companies offer leasing options where the panels are installed on your property and you pay a monthly fee for their use. Alternatively, solar panels can also be financed through loans or financing programs, allowing you to purchase and own them over time while making affordable monthly payments.

Q: Can solar panels be used on a backpack or portable device?: Yes, solar panels can be used on a backpack or portable device. These panels are typically lightweight and flexible, making them suitable for integrating into various portable devices. They can capture sunlight and convert it into electrical energy to power or recharge these devices while on the go.

Q: I was hearing that we need silver as a medal for the creation of solar panels, is this true? How much silver would be needed to make one solar panel? (if this is true): Some research has shown that small amounts of silver can improve the efficiency of solar panels. But this appears to be in the research stage and applies to the the thin film solar cells. Some solar panels makes use silver as the wiring in kind of a screen printing process, but you don't need to use silver, you can use copper or aluminum using different techniques instead. Generally the metal used is in small amounts and not a majority of the cost of the solar panel.

Q: Can solar panels be used in areas with high levels of electromagnetic radiation?: Yes, solar panels can be used in areas with high levels of electromagnetic radiation. While electromagnetic radiation can potentially interfere with the efficient functioning of solar panels, proper shielding and design considerations can mitigate such effects. Additionally, solar panels themselves do not emit electromagnetic radiation, making them suitable for deployment in areas with high levels of such radiation.

Q: When people buy small solar panels, what are the steps to making it actually charge or run something.. I'm completely new to this of course and im curious. what kinda of wire and other devices are needed and how do you attach the wire and everything..: It is quite complex from an engineering point of view. If the objective is academic, then it is worth the education for a small system. If it is to save money, whether it is viable depends what are the current rates where U are and a whole bunch of issues. The current technologies available are very far from one size fits all! Hope this answers your question
