Q:Solar Panels!!???!!!?
Solar power is harnessed through solar panels. These solar panels consist of numerous solar cells. That helps in producing the electricity
Q:Why are solar panels only 0% efficient?
Sunlight comes in many frequencies, that's why it's white. Solar Photovoltaics require a photon to displace an electron from a semiconductor and that only happens at one frequency depending on what the semiconductor material is, therefore only one exact frequency gets turned into power. They are working on using organic dyes or quantum dots to absorb the energy in different frequencies and re-emit the energy in the desired frequency. They also are working on using multiple semiconductor materials to try and capture more frequencies. The rest of the energy becomes heat which also reduces the efficiency of the solar cells. The lab record for solar photovoltaics is 42.8% efficiency and quantum dots promises to be 65% to 75% efficient. Keep in mind that fossil fuels are based on energy collected by photosynthesis over millions of years. The efficiency of photosynthesis with modern plants is about 0.5% and the theoretical maximum efficiency of photosynthesis is 6.6%. All of our current energy use is based upon a small fraction of 0.5% efficiency over millions of years.
Q:Powering my house with solar panels?
Homes vary tremendously in their usage. It will be a factor of 0: between a conservative house, and a heavy use one. To get the answer for your own house, check the electric bills. Also, the answer for the size of solar electric system varies with the location of the house. A Minnesota residence may get only 2/3 or /2 of what an ideal California house gets, even though both are sunny. As a data point, our California house has no air conditioning, no electric heat, no pool, and no big screen TV. We use maybe 5 - 8 kWh a day on average (more in winter, less in summer). We have a 3 kW solar array on the roof, and it roughly keeps up with our usage.
Q:How effective are solar panels?
Well, the maximum amount of energy you can receive with 00 percent efficiency is kilowatt per square meter. This is the energy that hits the Earth's surface. The best commercially available panels are 20-30 percent efficient. Cutting edge technology has gotten this percentage up to 50 percent, but you can't buy these for your home. If you're curious about efficiency, check out a panel's dimensions, find the area in square meters, and use that along with its Watts (divide by 000 to get kilowatts) to get your answer.
Q:How to make 2V 4.5A solar panel from solar cells?
To increase current, you connect the cells in parallel. But I think you really mean you need 4.5 watts rather than 4.5 amps of current. For an RC car, 4.5 amps would be huge, literally a regular car battery. So I think you mean you need a 2v, 4.5w panel. That would make more sense for an RC car battery. I went on OKorder and bought a 2v, 5 watt panel for about $30.
Q:how do i pick out solar panels to match my battery bank?
I don't know where you got the idea you have 8 hours of sunlight. Assuming clear skys and no dust, forest fires, clouds or other impediments, the average sunlight available in North America averages out to approx. kw/sq. meter. That's the maximum available, at midday. Multiply this be the efficiency of the cells (I assume about 0%) and it means about 00 Watts/sq m. Since you have said you have a tracking system, this works out to about 00 * .344 * 2 = 43W/h per day (per sq. meter).
Q:Maintenance for solar panels....?
All panels should be cleaned to function best. Brush or wash off dirt and leaves. They should be checked for structural integrity and lack of rust. Solar Thermal panels should be checked for signs of leaks and/or discharge from pressure relief valves. Solar Photovoltaic should be checked for electrical function and grounding.
Q:Can I power up 2Watt bulb using 2Watt solar panel power?
Hey, okorder.com
Q:Questions about charging batteries via solar panel...?
You did not give the AH rate from your 24V battery pack,therefore , unable to suggest a correct current rate solar panel. The solar panel open voltage rate at least 30V to charge a 24V cell. No harm to controller since the charging current is so small even bike is in running condition.
Q:Question about commercial solar panels?
In my experience working with solar panels, I've found that the panels themselves are robust and can last years. How that energy is transferred from the panel to perform work (sorry for the boffinism) is where the complexity emerges, namely due to the fact solar panels produce DC current, and nearly all of our electrical appliances use AC current. In most cases, solar panels will either send energy through a DC/AC inverter directly to be used for appliances, or stored in deep cycle batteries, then converted to AC using an inverter when the user wants to use his/her appliance. Now to answer your question: the solar panels will be fine, and could conceivably be in fine working order with AC current available IF... and I cannot stress this enough (namely through years of field experience dealing with solar powered scientific instrumentation that was working well and then mysteriously not working)... IF rats and other rodents haven't eaten through the wires. This is probably the most likely reason that a set of solar panels wouldn't be working in your given scenario. Hope this helps, and good luck!!
