- Q:how much energy does a kilowatt solar panel produce in a year? (average)
- You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.
- Q:quot;Does it take more energy to produce a solar panel than what the same solar panel can generate in its useful lifetime?quot;
- No. That lie is put out there by people who would lose out if solar panels ever became widely used. It does take about as much power to produce them as the panels make in 2 years in a good location, but considering their useful lifetime is at least 20-30 years, that isn't much. Wind power produces as much power as is used to create the windmill in 7-9 months in a decent location. Neither will ever produce as much power as they required to be made if placed in the wrong location, like in the shade or a non- windy area. No coal plant would ever make as much energy as it took to build it if no coal were provided either.
- Q:why don't we take a cue from mother nature and make our soar panels like trees? thousands of leaves or needle (like a pine tree) instead of one big flat panel? I mean it seems to work pretty good for all the plants i see why would it not work for us. It would be aesthetically pleasing and with the right engineering wouldn't it make them not have to worry about tracking the sun? i already have some ideas about the process of making them just no available labratory.
- Because we and the trees are trying to solve a different problem. We want electricity, a tree wants light (and some heat) for photosynthesis. In getting the electricity we use Silicon for solar panels. (Sometimes Gallium Arsenide). And we exploit the same thing in Silicon that allows them to be computer chips. The fact that they conduct differently when voltage is applied. But for a solar panel that is done essentially in reverse. We GET a voltage difference (electricity) from shoving energy through it. Look up junction bias on google or yahoo for explanation. But the DESIGN problem is: You have to couple these panels together the right way - according to their bias. You can't string them up willy nilly. There is a pattern. And when one breaks in this pattern. (I mean when the actual panel cracks, which they do easily as they are brittle). It can change the overall bias. This can make even be worse than if it was removed, it can actually fight against the working ones. The efficiency is there in arranging them like a tree, but the practicality of maintenance would be daunting.
- Q:how fast does a 25watt solar panel generate power to a battery? trying to figure out a conversion factor here to get a rough estimate of how many i would need to power my house, please help?
- To figure our how many you need, take a look at your power bill. It will tell you how many kilowatt/hours you used during the month. My bill says I use about 2000 kilowatt/hours per month, or about 2000 kwh /30 days=67 kw/h hours per day. That is 67,000 watt hours. To supply that with solar panels, you have to generate at least 67,000 watt hours, but you don't have a full day to do it, since you have to do it while the sun is up. So you put the energy into batteries during the day, so you can use it at night. A 25 watt panel generates about 25 watts when fully illuminated by the sun. If you fully illuminate it for an hour, you get 25 watt hours. If you get 2 hours of sunlight a day, that would seem to imply that I need 67000 watt hours/25 watts /2 hours=45 panels. But for most of the day, the sun isn't hitting the panel fully, so it isn't going to generate the full 25 watts. When the sun is 45 degrees to the side, you only get about 70%. When the sun is 60 deg to the side, you only get 50%. And what do you do on cloudy days? And the shorter days in the winter? To make up for this, you have to increase the number of panels to make up for the loss. So in reality, I might need double this number of panels, for realiable solar power throughout the year. That works out to about 90 panels, or ,250 watts worth for my house.
- Q:Can solar panels be installed on data centers?
- Yes, solar panels can be installed on data centers. In fact, many data centers are incorporating solar power as a sustainable energy source to reduce their carbon footprint and lower energy costs. The large, flat rooftops of data centers provide ample space for solar panel installations, making it a viable option for generating clean and renewable energy for these facilities.
- Q:How can solar panels be used for heating water?
- Solar panels can be used for heating water by capturing sunlight and converting it into electricity. This electricity can then be used to power heating elements or heat pumps that warm up water for various purposes, such as domestic use or swimming pools.
- Q:Can solar panels be installed on a university or college campus?
- Yes, solar panels can be installed on a university or college campus. In fact, many educational institutions have already embraced solar energy as a way to reduce their carbon footprint and promote sustainability. Installing solar panels on campus buildings can provide clean, renewable energy, reduce electricity costs, and serve as an educational tool for students to learn about renewable energy technologies.
- Q:I need to know where I can buy the parts or find them as scrap to make my own solar panels. Is there a cheap way of buying the panels or can I make them myself.
- You can buy a box broken cells and solder them together and save big bucks.
- Q:I need a solar panel which can light up 4 full loaded 5 rooms appartment houses
- good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
- Q:I'm curious to know if the small solar panels on a calculator (ie TI-32) could produce a voltage similar to what is used in a single-use (disposable) camera, approximately 4V.
