Production description
Most solar modules are currently produced from crystalline silicon (c-Si) solar cells made of multicrystalline andmonocrystalline silicon. In 2013, crystalline silicon accounted for more than 90 percent of worldwide PV production, while the rest of the overall market is made up of thin-film technologies using cadmium telluride, CIGS and amorphous silicon[7]Emerging, third generation solar technologies use advanced thin-film cells. They produce a relatively high-efficiency conversion for the low cost compared to other solar technologies. Also, high-cost, high-efficiency, and close-packed rectangular multi-junction (MJ) cells are preferably used in solar panels on spacecraft, as they offer the highest ratio of generated power per kilogram lifted into space. MJ-cells are compound semiconductors and made of gallium arsenide (GaAs) and other semiconductor materials. Another emerging PV technology using MJ-cells is concentrator photovoltaics (CPV).

- Q: I need to use solar panels to charge lead acid batteries in an off-grid application. I understand that solar panels have a open circuit maximum voltage and an maximum amperage under no resistance, and that one can optimize the power output by regulating the load (resistance). If so, is just connecting 2 -volt solar panels to a lead-acid battery inefficient? Are there devices that will maximize 2 volt output power (by varying the resistance)? Am I on the right track here? Thanks for any help.
- The answer is actually quite complicated, but if you're planning on building just a very small system, most likely, the panel will be small and weak. In this case, connecting a panel that is 8 volts open circuit directly to a lead-acid battery is probably the most efficient way to charge. There are charge controllers that you can buy, some of which actively track the maximum power point for charging your battery. Unfortunately, those controllers might eat 5 or 0 watts, just to get you another few percent of charging efficiency. If your panel is only 50 watts in the first place, you can see that this is not a good deal. If you're getting serious panels (clue: price $500 each), then you may very well benefit from a charge controller with MPPT (max power point tracking). Lead-acid, either a flooded cell like your car battery, or AGM, are the standard for solar energy storage. Lithium ion is better in many ways, being less sensitive to temperature, state of discharge, and they are also lighter. Charging them is also more straightforward with the right circuitry. The problem is, they cost like $500 per kWh, compared with less than a tenth that price for lead-acid.
- Q: I am curious about how much of the energy that a solar panel of a given size and capacity will produce in it's lifetime, and what fraction of that energy was required to produce it in the first place?
- At present the technology to create silicon solar cells is incredibly energy intensive. It is not logical to compare the cost of oil to the cost of a solar cell because they are not priced according to energy input. Oil has a strong advantage in that it is concentrated solar and geothermal chemical energy that has accumulated over millions of years. The price of oil does not reflect its energy content, but the cost to retreive it. Electrical energy used to produce a Photovoltaic cell is not priced in any proportion to oil. By some calculations it will take about 50,000 KWh of energy produced by the PV cell before it can recover the energy used to manufacture it.
- Q: Can solar panels be used in areas with high humidity?
- Yes, solar panels can be used in areas with high humidity. While high humidity may affect the efficiency of solar panels to some extent, they can still generate electricity. The performance of solar panels in humid environments can be optimized by using materials that are resistant to moisture and by ensuring proper installation and maintenance.
- 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?
- If you're in a sunny area, and the cost of electricity is high, solar panels can be worth it. But it's not a big moneymaker, it's something that pays back over long timeframes. We live in northern California, and our system is about break even, but that's because our electricity usage was low to begin with. If you want to see our system, look at the web page in my profile. Are panels worth it in your area? The only way to know for sure is to find a local installer in your phone book, and then ask for local references. If you can't find a local installer, that's a clue, and if they can't give you any references that are nearby, that's another clue. The panels don't actually store energy, the energy is sold back to the power company when what you produce is more than you consume, driving the meter backwards. Again, this is not a big moneymaker, and in fact, it may be impossible to make a profit, depending on your local laws.
- Q: I am completely ignorant on this subject. I was just wondering out of curiosity of how many solar panels and equipment that it would take to run a central ac for a 2500 sq ft home and a pump for a medium sized pool. I'm talking running ac for like 8 hours a day to keep around 65-70 degrees and running the pump 24/7. Just looking for a general ballpark answer.
- Solar panels are not going to be able to run a pool pump 24/7. They will only produce their rated electricity for 4 to 8 hours a day. For the balance you will need a grid connection or a battery backup. Running the AC would require different power levels depending upon humidity, outside temperature levels, solar gain for the house, and insulation levels. An underground house in Maine will be much easier to AC than a Glass house in Arizona. First find the power requirements. If you had the existing equipment they will have a label with the power requirements or the minimum breaker required if nothing else. For example the pool pump may require a 0 amp 240 breaker while the AC may require a 30 amp 240 breaker. That would be 2400 watts for the pump and (30 x 240) 7200 watts for the AC or a total of 9.6kW each hour of operation. (max) You will next need to find the rated capacity of the solar panels. If each panel were rated at 300 watts then you would need 32 panels for the daytime use and perhaps more to fill in a battery backup. All the numbers are very rough estimates.
- Q: Plz also label the price for the panel. I want a small panel but can produce a sufficent amount of energy. thank you :)
- This one.
- Q: Where can I find the info (sites) that clearly gives the anatomy of a solar panel?Likewise, I want to know where can I find (sites) the solar panel that produces 3.75 v? Thank you very much!!!
- You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
- Q: Can solar panels be used for irrigation systems?
- Yes, solar panels can be used for irrigation systems. Solar energy can power the pumps and other electrical components required for irrigation, reducing the reliance on fossil fuels and making the system more sustainable and cost-effective.
- Q: So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
- solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
- Q: I want to purchase some or one solar panel for my home. I don't know where to buy them from. I've loooked online and if i could buy them online that would be best, but if you knew of a website that has good prices than that would be great!Thanks
- Are you aware of the complications that go along with installing a solar system? A solar panel might put out about 00 watts at 24 volts DC. What would you use it for. The typical solar system has a lot of panels connected in series. The output is connected to an inverter to make 20-240 volts AC. This is connected to the power grid if it is to be used. Also if it is felt that the system should provide power during an electrical outage, there will be batteries. How big would you wan it to be? Mine has forty panels with two inverters. It supplies all the electricity for the house, with some left over to supplement my gas heat. Read the Q and A in the Search box at the upper right of this page, by searching for solar panel. Also study all you can get your hands on.
