- Q: What is the main material for making solar panels?
- You can also according to their own needs, according to the power to buy a good package of solar photovoltaic products.
- Q: Science homework! I need to explain how a solar panel works and draw a Sankey Diagram for the solar panel, can anyone show me a sankey diagram for a solar panel or explain how a solar panel works?? ILL GIVE U BEST ANSWER IF U HELP WITH BOTH =]
- Build okorder /
- Q: HIToday i was using my BB gun and shot my dads solar panel. I want to fix it for him because he spent a lot of time trying to get the solar panels. All i broke was the glass on the front, what is the glass and where can i buy new glass for it?
- Even if you can buy solar glass, you CAN'T properly repair the panel for the cost of having a professional do the work.
- Q: I need a new roof soon and I was wondering what the difference in cost would be from a standard shingle roof to a roof including solar panels. Does anyone know the cost difference?
- The solar panels are very expensive to provide much power. If u go that way do not skimp on the support as a high wind will blow them away. In Ecuador I put in a remote site for communications. It was working good when a Strong wind blew $0.000 worth of solar panels all over the jungle.
- Q: im interested in starting a solar panel manufacturing company. ive researched on how to make them and it doesnt look too hard, and is definitely something i can figure out. i would be starting from nothing so my question is what are the chances of me actually selling a lot of panels and the business actually succeding?thanks
- At this very moment, most of the people already have an idea on how to create their own solar panels, And creating your own company takes a lot of necessities such as permits ans other stuffs like that,.
- 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.
- in case you had 2 mind cells to rub at the same time, think about nicely-known that at present's image voltaic panels are more suitable in each thanks to the antiquated, out of date, artifacts you're blathering and spewing about. If any image voltaic panels are happening the white domicile, they're going to be cutting-side. once again, technological awareness and expertise have moved on and left you choking of their dirt, scratching your azz and furrowing your neanderthal little foreheadin a futile attempt to understand what has occurred.............
- Q: Can solar panels power an entire home?
- Yes, solar panels can indeed power an entire home. With advancements in technology and improved efficiency of solar panels, it is possible to generate enough electricity to meet the energy demands of a typical household. Additionally, by installing a battery storage system, excess energy generated during the day can be stored and used during nighttime or cloudy periods, ensuring uninterrupted power supply.
- Q: Can I add reflectors or mirrors around the solar panels to increase the power they generate?
- You could (an example of concentrating sunlight is called cloud gain, where the edge of a cloud will intensify sunlight as it passes between the sun and your panels), but that will make your panels run hotter and will probably reduce their life. It's better from a system design standpoint to simply get another panel or two. DK
- Q: but is that per day, per hour or minute?How much watts does the average AC unit use?How much does an energy efficient lightbulb use?All in all let's hypothetically say we no longer use the electric company for our energy source, How many of these panels do you estimate it would take to supply our small home?
- Some great answers 23 max watts is per hour I live in an area that has 5.5 average sun hours per the solar insolation data which would give me a base of 676 watts produced per day for one panel. That 23 watts is most likely STC or standard test conditions which is far from standard it is ideal 70 degrees Farenheit with a 000 set flash PTC or physical test conditions are not always on labels and are not always accurate because of varied conditions. Heat has a huge factor on PV production. The panels should be derated by for the following reason ampacity correction or line loss Temperature correction PTC correction Inverter loss these corrections account for about 5 % on standard panels Our 676 watts per day has been dropped to 574 watts per day per panel Lets start with the light bulb. a standard 60 watt bulb uses 60 watts per hour. With the one panel we have chosen it would produce 5 hours and 45 minutes of illumination If we switch to a 5w CFL we get 38 and one half hours of illumination quite a difference yes Central Air will use about 2000 to 2500 watts per hour.This rule is not hard and fast as units will vary as well as conditions Lets use 2000 per hour times 8 hours of use is 6,000 watts we need 28 panels just for the ac. Probably another 28 for the rest of the house Of course these panel must be true south at 5 degrees mounted With a years worth of electric bills and a site visit I could come allot closer but lets say you need 60 of these panels this system would provide 973kHw per month at my location of 5.5 sun hours per day This would be a grid tied system as most state rebates require a grid tied system to qualify for rebates
- Q: Can solar panels be used for powering wireless charging stations?
- Yes, solar panels can be used to power wireless charging stations. Solar panels convert sunlight into electricity, which can be used to charge batteries or directly power electronic devices, including wireless charging stations. This allows for clean and sustainable energy to be used for wireless charging.
