Q:Ok, so my homework was to research and write about how solar panels and solar furnaces work and about their construction. We didn't even take one lesson on it in class and we are not allowed to copy and paste much and have to keep it simple wtf? Its soo annoying as we have hardly took it in class. Please can someone help.
Well solar panels conduct electricity from the suns waves and turns it into dc current then it is either put into a grid tie inverter to change it to AC and it makes you meter go backwards instead of forwards. or if its not a grid tie inverter it is just put into batteries as dc then changed into AC from the inverter and then used for household appliances. nothing really does run on DC that is why it has to be changed. and for solar furnaces if you mean a water heater that works by a substance here in Pa its antifreeze is heated up by the sun in the panel it is in a continous loop and that is what gets heated up the water then flows over tow of the tube that contains what ever substance such as antifreeze and heats the water.were the water and the tube that changes the water from cold to hot is called the heat exchanger. the substance is actually get heated first then the water. solar heating for water accounts for 29% of water heating in the us. Now if you mean solar furnace as in passive solar thats completely different because here in Pa if we want it our houses have to face to south to get the suns rays. (alot more windows) and there is a cement slab placed only on the south side of the house and it has insulation covering it. There is a certain type of glass that is used for this that will allow the suns rays to come in and let the heat in for the summer and also for the winter. the main place for that would mostly be the first floor of the house due to the height of the windows and the angle of the sun(pa in the summer is 73 degrees and in the winter its 27 degrees) thats when the second floor would be ok to heat the rooms. Hopefully i helped and i explained it in a way that you can understand.
Q:
Yes, solar panels can be used in developing countries. In fact, they can be a highly effective and sustainable solution for providing electricity in areas where access to energy is limited. Solar panels are easy to install, require minimal maintenance, and can harness the abundant sunlight available in these regions. Additionally, solar energy can help reduce reliance on expensive and polluting fossil fuels, improve access to electricity for schools, hospitals, and homes, and contribute to the overall development of these countries.
Q:I've been figuring ways to keep water thawed out this winter, and this bucket seems to be the easiest thing. What kind of set up (solar panel) would I need to feed this 260 watt heated bucket?
Unfortunately solar panels are low output,generally only 2 volt and very low amperage,so you would need to build a multi panel array with a DC-AC converter all together costing several hundred dollars which would only work during sunlight.Just roughly figuring,about $800. Plan2-Solar charger,battery bank,and DC-AC inverter so it would work 24hrs a day,also several hundred $$. Solar power does just not seem feasible(to me)in this application.By far the cheapest set up here would be an extension cord fromhouse to the bucket.260 watts per hr is a fairly lightweight draw,even not figuring the thermostat's cycling it on and off as needed.Electricity is sold in kilowatt hours(000W/hr).This bucket would use(not allowing for thermostats control lowering it)appx 6000watts or 6KW per day.Depending on your electrical cost per Kwh it would cost very little to run.(In my location appx 50cents a day) or appx the same amount as my computer(325watts total)) Note that that would be a maximum rate,and would actually be less due to thermostat cycling off and on as needed.
Q:
Solar panels can still be installed in shaded areas, but they may not be as effective in generating electricity compared to panels installed in direct sunlight. The amount of shade and duration of shading throughout the day will impact the overall energy output of the solar panels.
Q:Im looking at making a self build iPad solar panel charger, Is it possible to get a small solar panel, a battery to hold charge and then a USB output? nothing fancy, just power in and power out?
Homemade okorder
Q:i want to join multiple solar panels into a bank so i only need one length of wire, i am going to use diodes to stop them sending power back into the one before it. is this ok or do i need something else?
Check out some of the videos on YouTube on this subject.
Q:What sort of maintenance is required for solar panels....?
New sunlight panels are easy and shiny they usually look cool. Then they get dirty with dirt and particles caught on the wind and residues left in the back of by rain and birds. Solar panels need to be by and large cleaned and maintained to be able to hold them running effectively and maximize the quantity of sunlight they convert into electricity. Unlike home windows your sun procedure wants to have a clean and clear surface to make sure they are working at their highest efficiency. If they are not at their surest performance it approach they are not producing the amount of electrical energy that they might be. Sun panels will attract filth, dirt, soot, pollen, tree sap and salt crystals in coastal areas creating a nice layer of dust. This sediment reduces the amount of light reaching the silicon cells underneath the glass floor and reduces the panel's effectiveness. A solar panel that has on no account been cleaned would be producing almost a 3rd less power than it or else could be. Some have mentioned a ten to fifteen percentage lack of sun output as a result of dirty panels. From the ground the panels may just appear to be clean, similar to your windows. Up close nevertheless you will see the grime that has built up from the grime and pollution within the air. A extra visible deposit that can be left on panels is fowl droppings. These tend to wholly block the sunshine from areas of the photovoltaic panel and may colossal scale back its effectiveness. See much more about sun panels preservation beneath link
Q:Has anyone actually used those kits online like energy4green or earth4energy to build their own solar panels or windmills? I'm so tempted but with my budget can't afford to waste any money. They have a 60 day money back policy but that doesn't include the money used to buy the supplies to try and build the things. My electric bill is almost $300 a month due to my stay at home disabled veteran husband who went from Utah snow to Florida sun and he has to have the AC on really cold. If anyone has actually built one can you tell me of your experience and if it actually is worth the money? I do lots of D.I.Y. projects but am a novice with electric besides installing a ceiling fan and changing out a light switch.
Electric panels are not feasible for most people. They are two super thin layers of polarized material. When the sun hits them electrons move from the first to the second layer with an amount of force. You can't duplicate that at home. What you could do is setup solar heating panels and run them against a Stirling engine. This technique is typically more efficient than normal electric panels anyway in industry. They have heat on one side and cold on the other to generate force. Hook that to any generator to produce electricity. If you are successful building a home system, blog about it, others will want to know precisely how you did it.
Q:So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
Q:I'm part of the Sustainability group at school, the school principal is a d**k and doesn't care about the environment, he only cares about money.Me and the group will be talking in front of him and the school council (the people in-charge of the school's money) To convince them to put solar panels on the school roofs.I know that it definitely will help the school save on electricity bills, but it WILL cost a lot of money to put them in.In the end we just wanna reduce carbon emissions!HELP :)
Unfortunately installing Photoelectric Solar panels on your school would probably cost more than the entire school budget. In order to make this sort of proposal you would need to have some hard numbers to show exact dollar amounts of costs and benefits. You would need multiple quotes from companies that install solar panels and information from the electrical company that would have to tie the system into their grid. This is a HUGE undertaking. If you really want to reduce carbon emissions, suggest ways to reduce the energy use within the school instead of converting to solar. Better windows, doors, and roof insulation. If you have a leaky roof, fixing that would get rid of water damage and better insulate the school thus saving energy. Suggest plans to reduce electrical usage like having computers go into Hibernate mode after 0 minutes, turning off lights in rooms that aren't getting used, etc... Many people are fooled into thinking that solar power is this awesome free energy source. IT is NOT. Solar panels are great for powering small items or for getting power when you have no other way of getting connected. However it takes MORE electricity to create a solar panel than the solar panel will ever produce in it's ENTIRE lifetime. Do some research into the production of silicon crystal and semiconductors and find out how solar panels are made. Until the technology improves greatly, solar is not a green power source other than generating money.
