275W Poly Solar Panel for Small Solar System Stock Information
- Q: During the summer my house uses about .47 kw/h I am wondering what solar panel do I need to cover most or all the electric bill. A link would be helpful too :)
- The correct answer depends on how much total energy you use during the day and whether or not your utility allows something called net-metering. In net-metering, if you make more power during daylight hours than you consume, the meter goes backwards. Then at night the meter goes forward again. With net-metering you only pay for the difference.
- Q: looking for a solar panel to charge my laptop on the road, macbook is 60 watt 6.v 3.5a, what should i be looking for in a solar panel?
- Well that's a good idea,,,here's what ya need..First you need an array that will overcome the drain effect created by the in use or sleeping laptop...that is best solved by averaging out the real use of the machine in terms of watt/minutes...If you check your transformer you'll see it has a capacity which you have cited however the true use of the computer is about 40-50 percent of that in watt/minutes..but only while your using it and when in the sleep mode the watt/minute value drops even more to about 5%.... So if your actual use consists of 2 hours of use per day at 50% and 2 hours at 5% percent the actual wattage draw is only averaged out at 34watts/minute. optimally your panel should supply all your power from its photovoltaic conversion ,but in the real world application the panel only recharges ,over a period of time, the used power. So if you had a 5 watt (@ 2vdc) panel working 480 minutes and used up 35 x2=700 and 9 x2=8 for a total of 78 watts you would have 5 x 480 = 7200 watts input and a parasitic load of 78 watts in the two hours...well within the recharge state required.. For a little safety I would permanently wire a cigarette lighter type plug to the end of the panel this will keep the polarity correct and serve as a quick disconnet means...Also add a fuse at .5 amp... a good place to get these are on the internet....some are very expensive some a very cheap --go for a middle of the roader...Have a good one from the E...
- Q: im making an energy efficiant house for science class and i need to price the house. im putting solar pannels on the roof and would u please tell me how much they are per like 2 sq. feet of a pannel?
- It is tough to answer that question since efficiency is something u pay for thus the price can varies greatly but here is a few web sites you could check out and most would probably be happy to help with any info if you contacted them and the last one has allot of other info that could help like handling waste and water usage in this home
- Q: I want to be more green and if I get the panels will I still have a regular electric bill?
- The most cost-effective solution, which the vast majority of new installs use today, is solar alongside the regular power company. That way, you need no batteries, and if the solar array isn't producing enough at any given time, you draw from the electric company. When the array is producing more than you need, instead of just throwing that power away, the power company buys it (usually). In short, yes, you will still have an electric bill, but a smaller one. On our house, the electric bill was a little less than $5 a month, with an end-of-year settlement of an additional $2. How much does it cost? Unfortunately, that's like asking how much personal transportation costs. Some people need a van to transport the kids to soccer, some may get by with a motorcycle, others may need only a bicycle. The best thing is to contact a professional installer to get a quote based on your location and electrical usage. Solar electric does not make financial sense in all areas. Our array cost $2,000 but don't use that as a guide. Yours might be 0 times that, or half that, depending on your area and needs.
- Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be
- Yes its true! electric bills are getting higher and higher. That's why a lot of people or businesses turn to alternative sources of energy. It is a little cheaper but can still provide the same level of energy. It is even good for the environment. If you are considering a switch for your energy provider, learn first about the different alternative sources of energy at businessswitchonline .uk. It might be helpful in making up your decision. Also, solar panels will depend on how large your house is or if it is really qualified for solar energy. You need an energy provider to have an evaluation of your house before you set up a solar panel.
- 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: Can solar panels be used to power a restaurant?
- Yes, solar panels can be used to power a restaurant. By installing solar panels on the rooftop or in a nearby area, the restaurant can generate clean and renewable energy to meet its electricity needs. These panels convert sunlight into electricity, which can power various appliances, lighting, and other electrical systems within the restaurant. Additionally, solar panels can help reduce the restaurant's reliance on the traditional power grid, leading to potential cost savings and environmental benefits.
- Q: How do solar panels impact the local job market?
- Solar panels can have a positive impact on the local job market by creating new employment opportunities. The installation and maintenance of solar panels require skilled workers, thus generating jobs in the renewable energy sector. Additionally, the growth of solar energy can stimulate the development of related industries, such as manufacturing and research, further boosting employment prospects in the local area.
- Q: Are solar panels fire hazards?
- Solar panels are generally not considered fire hazards. While there have been some isolated incidents of fires related to solar panels, they are extremely rare and typically caused by faulty installations, damaged equipment, or external factors. When installed properly and maintained regularly, solar panels pose no significant fire risk.
- Q: trees vs solar panels who would win?
- If it was a physical battle, solar panels. It's like burning ants with a magnifying glass. Aim the solar panel at the trees and you have a forest fire.
