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.

even although photograph voltaic panels cost quite some funds up front and don't furnish a hundred% performance, over the existence of the device, a photo voltaic panel array can shop maximum folk funds. producers furnish 25 365 days production guarantee on panels and panels will often proceed to supply after the guaranty has expired. whilst a device is designed to supply 'internet metering' truly producing as a lot power a house makes use of it (the two by way of batteries or pushing it back on the grid the payback on the cost of the panels would be measured by way of dividing the device cost by way of the month-to-month power expenses. With the passage of a 30% federal tax credit on qualified platforms and assorted state classes, platforms will payback often in under a decade consistent with utilization factors and climate.

Q:Most solar panels (the flat ones that go onto roofs of houses) reject electricity produced by the panels if they are too low in voltage. For example, on a cloudy day, although the panels may still get some sunlight to produce some electricity, it is rejected because its too low in voltage. So, does anyone have any ideas?

apart from, the way image voltaic panels are under pressure jointly can impact the voltage output. If the panels are under pressure with the output of one connecting to the enter of the subsequent, or in sequence, the voltages of the panels upload up. case in point, in case you have 4 2 Volt panels under pressure in sequence, the finished voltage of the array could be 40 8 Volts. If the panels are under pressure so as that each and one and all their inputs and outputs are linked, or in parallel, those comparable 4 panels could have a entire voltage of 2 V, however the gadget could have 4 circumstances the present (Amps) of one panel.

Q:My plans are building several solar panels and have a battery bank. I want to be able to power the refriderator and freezer and occationaly an electric grill. How would This work exactly and what would the best way to hook this up to make it work? I want to be able to convert DC to AC. How many batterys would I need to make this work. I know when Civil unrest happens I want to be prepared. How would Wind Power work If I can get the equipment I need?

Solar panels and wind/water turbines all produce the energy and feed it into the batteries. Outfeed from the batteries thru an inverter to an electrical panel. From panel to outlets, into which you plug standard appliances and items. You can also get some appliances that run off of 2volt. Check with r.v. companies and suppliers for these. You can also run low voltage wires straight from batteries to switches to lights, fans, etc if you put in 2v ones. Just like your car has lights, fans (ac blower), and radio. As for how many batteries you need will depend upon how much ebergy you will use. You will need to figure how much all of your items use per hour. Then figure how long your charging device could be down for at a time. Solar panels will not charge at all for the 8-2 hours of nightfall depending on your area. Wind turbines will charge day and night so long as wind is of sufficient speed. Water turbines will charge 24/7 so long as water source(creek, stream, river) doesn't run dry. Neccessity/hr=N, time without charging =T. N times T = the amount of backup power you need to get you thru till charging sysytem kicks back in.

Q:Are solar panels recyclable?

Yes, solar panels are recyclable.

Q:Can solar panels be installed on a condominium or apartment building?

Yes, solar panels can be installed on a condominium or apartment building. However, the feasibility and process may vary depending on factors such as building ownership, structural integrity, and local regulations. It is important to consult with professionals and obtain necessary permissions before proceeding with the installation.

Q:Hi, I bought 50 6X6 inch solar cells, I also bought a 40 amp diode, I still need to buy a battery, and inverter and a voltage controller, could you tell answer me the following questions:) I would like t build a small panel at first, (may be 0 X 0 inch), with that I would like (or at least to try) to power my laptop for the hole day, so I wont receive a very high amperage, yet, all the inverters I saw at e-bay are rated over 400 amp, if I buy a 400 amp inverter, can I use it with such a small amperage?2) what about buying a small car inverter, will it work?3) suggestion about the battery and the voltage controller will be kindly appreciated.Thanks

I'm guessing that each of those solar cells is just 0.5 volt at max power, so if you make a 2-inch square panel, you will get 2 volts - not enough for the inverter. A car inverter is notoriously inefficient, but it would work if you connect it to a 2-volt battery. You cannot generally connect such an inverter to solar panels alone. The battery supplies the peak current that the inverter needs, and the panel charges the battery. To charge a 2-volt battery, you will want 36 cells, generally, which give you an 8-volt panel. You can buy an inexpensive charge controller somewhere. If your laptop will run off 2 volts directly, you can skip the inverter and be much more efficient. Or if the laptop runs of (say) 9 volts, you can use about 40 cells to get 20 volts, get the proper power plug from Radio Shack, and plug the panel directly into the laptop.

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?

how fast? what does speed have to do with? Electricity travels at close to the speed of light. A house requires kW at a minimum, and 2 to 5 kW at peaks. You can do the division, 5000/25 = 40. Plus, solar panels operate only 4 to 8 hours a day in the winter, so you need to multiply that number by about at least 6 to allow for the dark hours. .

Q:Can solar panels be used in areas with high levels of electromagnetic interference?

Yes, solar panels can be used in areas with high levels of electromagnetic interference. However, it is important to ensure proper grounding and shielding techniques are implemented to minimize the impact of electromagnetic interference on the performance and efficiency of the solar panels.

Q:What is the impact of bird droppings on solar panels?

Bird droppings can have a negative impact on solar panels as they can reduce the efficiency of the panels by blocking sunlight. The droppings can create shadows and reduce the amount of sunlight that reaches the panels, leading to decreased energy production. Additionally, the acidic nature of bird droppings can damage the surface of the panels if not cleaned regularly, potentially reducing their lifespan. Therefore, it is important to regularly clean and maintain solar panels to ensure optimal performance and longevity.

Q:In some countries where electric generation is low, they are not available easily.

Believe it or not, solar panels are so expensive in this country because of government subsides. Without market competition, companies have no obligation to compete with each other on price. If our government would stop paying people to buy solar panels and giving solar panel companies tax breaks, companies would be forced to lower their price and raise their quality in order to get you to buy their product. This would be true of oil/gas, corn, soy beans and a number of other companies and products as well.
