Q: The Physics club in our school is trying to convince the Board of Ed to install solar panels in our school, and i was just wondering if anyone with some experience or real expertise in solar energy. I need some points about their usefulness some real pros and cons on maintenance, etc. Anything will help. Personally i would be perfectly for the idea, but i heard that the overall cost of installing them is much higher than the cost of the energy saved and government subsidies, but ive only heard about this.: nan

Q: i want to go off grid with solar panels but i need to know how many vots and watts i need to power my house: Complex question.... Let me try to simplify it some: Make a list of every electrical device you MUST have. Add to the list how many hours a day it is actually ON. Add to the list how many watts (listed on the label or Volts times Amps) the device uses. (If you have a measuring device, use it.) For each item, multiply volts times hours = watt-hours (this is total energy used per day). Also, add the watts column for all the devices (this is the maximum instantaneous power to be used). Your solar panels should be able to provide power for your total load, so your panel's output power should equal the maximum instantaneous power used. If you can limit how many devices are used at a time, you may be able to reduce the panel size. Look at the total watt-hours. This is the total energy. Your panels generate maximum output when they are perpendicular to the sun at noon on a clear day. They generate reduced output in the morning and afternoon. They also generate substantially reduced output on cloudy days. Also, did you want electricity at night? On cloudy days? You will need batteries.. lots of batteries. And batteries are inefficient.. figure about 50% efficiency after a few years. Basically, here is a very rough formula: Panel_watts = Load_watthours / hours_sun_daily / 60%_angle_efficiency / 50%_battery_inverter_efficiency Once you've figured out the panel's watts, watts/volts=amps. Your system can be 2V with more amps, or 48V with /4 the amps... but the watts are the same. Just the wiring is different. For the battery bank, you need to determine how much backup power you will need for nights and cloudy days. Look at the watt-hours needed at nite, multiply it by the number of days and then by 2, to allow for battery aging. Unless you only have a couple devices and an LED light or 2, it is going to be VERY expensive.

Q: discription how does solar panels save energy: Solar panels don't save energy, they just utilize a different source of energy. To the extent that it replaces energy from sources which are limited themselves (such as fossil fuels), solar energy does save those resources.* The main benefits of solar energy are environmental in the sense that it is nonpolluting,* but using solar energy doesn't reduce actual power consumption. *Excludes environmental costs of producing the solar panels themselves, but these are much smaller than the environmental benefits of solar vs. fossil fuel (which has infrastructure costs of its own).

Q: I have made a 5v dc 52watt solar panel and I going to be trying to charger 4 2v dc 55ah batteries. I get about 6 hours of sun on my panel. Spec below, is that a big enough panel to charge the batteries???I have 30 3x6 solar cells wired together Cell Specifications: (Watts): .75 Wp (Amps): 3.5 Imax (Volts): 0.5 V max which is where I got my 5g 52watt max (if math is wrong plz tell me) The Battery type: 2Volt 55.0ah NB Sealed Lead Acid Battery. I am using a mppt solar charger.: I don't think so, but if it did, it would take a very long time. You need enough wattage or amps to push the power in the battery and 3w may not be enough. You would be better off with a small 2v battery, maybe the type they use for emergency lights. I would use a sealed battery for this type of setup because car batteries are designed for heavy charging with alternators from 60 amps and up.

Q: our school spends around $0,000 dollars on energy.we want to know how much money would installing solar panels on the roof save our school.: Where do you live? In almost all areas, solar power is currently really expensive. It looks like it'll be 0-5 years before they're cost effective... sorry to tell you! If your school is a tall building with few similarly tall buildings/trees around it then mini-wind turbines might be worth a look. You'd have to measure the wind for a year or so to get an idea of whether it's worth it though - in most cases mini wind turbines aren't very good either!

Q: Which kit did you use?How easy was it to build? How much did it cost to build the panels?How many kw or watts does it produce?Any other info on the kit or panels you built would be helpful.Thanks!: Firstly, forget about making your own PV panels, while you can (if your chemistry is up to it and the home lab well tooled up) make a small PV cell, the efficiency will suck and you will never make enough to produce a reasonable amount of power. What you can do is to build your own solar thermal system to produce hot water (solar thermal makes better sense then PV in most domestic situations anyway), black painted central heating radiators under perspex, rockwool behind, small pump running a water/glycol mix through a heat exchanger controlled by some trivial electronics... Job done. As long as you don't try to run too hot, you can get a hundred watts or so of heat per square meter from such a solar thermal plant. Regards, Dan.

Q: Hi,I am thinking about getting solar panels installed. # I like to cut my electric bill. #2 I like to eliminate my oil boiler and use some sort of electric boiler.I use about 5000-30000 KW per hour( winter-summer). My oil bill is around 600 month winter time. Over all i pay around 4000 a year. My electric bil now is around 2000-2500 year. Is this possible? I live in NY. I heard you can get up to $35000 rebate from LIPA( Electric company) and 2k from federal and 5k from State( is the state or federal every year?, how does that work). Any help is appreciated.: There is a variety of information available on the internet regarding solar panels. You didn't say if you were interested in installing a photo-voltaic system to generate electricity, or if you wanted a passive solar system. From what I've read, the method that would give you the greatest payback for your investment is the passive solar heater. I can't give you exact instructions on how to construct one of these units, but there are many websites with instructions. My older brother had one of these mounted on his old farmhouse. He said his furnace didn't run all day during the cold Wisconsin winters. The government rebates or tax credits are usually a one time deal. They may pay for part of your installation, but they won't cover the whole cost. The only thing I've heard of that will pay you every year is a wind generator tied into the electric grid, but thats another posting. I'm including a link to a site that will show you how to build a cheap solar heater that you can try yourself.

Q: Do solar panels require a specific type of wiring or electrical setup?: Yes, solar panels require a specific type of wiring and electrical setup. They need to be connected in series or parallel to form an array, and the wiring should be designed to handle the direct current (DC) generated by the panels. Additionally, an inverter is typically used to convert the DC electricity into alternating current (AC) for use in the electrical system of a building or to be fed back into the grid. It is important to follow electrical code requirements and consult with professionals when installing solar panels to ensure a safe and efficient setup.

Q: How do solar panels affect my electricity bill?: Solar panels can significantly reduce your electricity bill by generating clean and renewable energy from the sun. By harnessing solar power, you can generate your own electricity, thus reducing reliance on the grid and lowering your monthly utility costs. In some cases, solar panels can even result in net metering, allowing you to receive credits or payments for surplus energy that you feed back into the grid.

Q: How are solar panels made?: Solar panels are made through a complex manufacturing process that involves several steps. It starts with the production of silicon wafers, which are sliced from silicon ingots. These wafers are then treated with various chemicals to create a semiconductor material. The next step involves creating a sandwich-like structure by placing a layer of phosphorus-doped silicon on top of a layer of boron-doped silicon. Metal contacts are added to both sides to collect the generated electricity. Finally, the solar cells are encapsulated in a protective layer and assembled into a panel, ready for installation and use.
