- 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 store excess energy?
- No, solar panels cannot store excess energy.
- Q: Can solar panels be used for air conditioning?
- Yes, solar panels can be used for air conditioning. Solar panels generate electricity from sunlight, which can be used to power air conditioning units. By using solar energy, homeowners and businesses can reduce their reliance on traditional electricity sources and decrease their carbon footprint. However, the efficiency and effectiveness of using solar panels for air conditioning may vary depending on factors such as the size of the solar system, location, and energy requirements of the air conditioning unit.
- Q: solar panels or light parts
- They make lights that have solar panels built into them. Due to the solar cell, they can sense when it gets dark and thus switch on the light automatically. Look at Northern Tool or Harbor Freight web sites for ideas.
- Q: If a solar panel is a .5kW system, what length of time is it putting out that much power? Every hour?
- I think it refers to the maximum power it is capable of. Of course, it won't really have this output because it's energy output (kWh) is dependent on it's energy input...
- Q: What is the difference between Photovoltaic Panels and Solar Panels?
- Dear friend, Photovoltaic Panels and Solar Panels are the same products.
- Q: Why are they placed there? How come they aren't placed on the floor or window.My fiance and I are interested in putting solar panels on our new home. I was really curious and google wasn't giving me the answer. My roof is pretty small in our new house and I don't think it would fit there. Why is it usually placed there and is there another place? You will be chosen as best answer if you answer all my questions. Thanks in advance, and I would appreciate if nobody is rude. Otherwise, I will have to report abuse.
- Solar panels are placed on the roof because many times the roof has good exposure to the sun providing the roof is not blocked by trees or something else so that sufficient sunlight wouldn't be absorbed. Also the panels would more likely not get damaged on the roof opposed to being in the yard. If they were mounted on the windows, how could you see? And, the windows could easily break and then what would happen to the panels? Placing the solar panels on the floor would not be practical. A lot of sunlight is needed for the cells to produce electricity and how much goes on the floor? Most roofs are at an angle which could perhaps improve the amount of sunlight the panels would get, and roofs provide a lot of unused space. The roof is the best place. Furthermore, roof solar panels are available now to blend in better with the roof so that they are more pleasing to the eye. Even if you have a small roof, some panels could be placed there provided the roof is not blocked so that the sunlight it gets would be sufficient (about 4 or 5 hours of sunlight a day is needed). And, if you needed addition panels, they could be mounted in your yard as long as the mount was close to your power box and received sufficient sunlight. I applaud your desire to use solar panels. You could possibly save 50 - 90% on your electric bill and help your environment at the same time! A Win - Win situation!!
- Q: Can I add reflectors or mirrors around the solar panels to increase the power they generate?
- In the 70's when silicon was really expensive, they played with using fresnel lenses to focus the sunlight on small solar cells but these panels had to be on heliostats and aimed directly at the Sun. These days, with nano-technology, there's a renewed interest in the concept but the fundamental weakness is that there are diminishing returns, at some point, it's just less expensive to have more solar cells.
- Q: thinking of getting a portable solar panel laptop charger...may be a stupid question but may be a very intelligent one as well ;)
- small solar panels will produce some electricity under artificial light, but not nearly as much as in sunlight. Is that enough to charge your laptop? probably not, but you would have to try it to be certain. Of course you would have to orient it to get the maximum light, and that may not be possible in the tight confines of an airline seat. don't forget they dim the lights at night. Bottom line, won't work. Some aircraft have a connector to allow you to power (and charge) your laptop. It you have that, you need to get the right cable. .
- Q: Can solar panels be used to power electric vehicles?
- Yes, solar panels can be used to power electric vehicles. Solar power can be harnessed to charge the batteries of electric vehicles, providing a renewable and sustainable source of energy. This allows electric vehicles to operate with reduced reliance on traditional grid electricity and contributes to a greener transportation system.
