- Q:where I can find solar panel the has 4.8 volts? Like those solar walkway light or something that has 4.8 volts solar panel.Do you think I can get it from home depot?
- heres a list of solar companies. perhaps u could browse them
- 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:Are photovoltaic cells the same as solar panels?

- Q:when we say a solar panel has 20% efficiency, do we mean that it converts 20% of sunlight reaching it into electricity or that it converts 20% of visible light(which is only 7% of sunlight) into electricity?
- Photo-voltaic solar cells use the visible light range (photons) for the conversion of sun's rays to electrical energy. The potential of solar radiation is ,353 Watts per square meter, but that is mostly a measure of heat, or infrared radiation. The visible light is actually a small portion of the spectrum. You have struck on a problem associated with photo-voltaic cells. Infrared radiation acts to heat up p-v cells (heat stress), causing them to be much less efficient. It would be interesting to see a hybrid p-v panel that is cooled with fluid or air running through it. This would increase efficiency of the p-v process while providing a heating source. This in turn could be used directly for heating or for production of electricity through a generator system.
- Q:My solar panel is 24long..It is set at 45deg..the arms are 8quot;long to achieve that angle for winter. I need to get to 7deg for summer..how long will the new arms need to be?..in layman's terms please...thx
- You did not give the details of how the legs are attached to the panel. I did some calculations on my right triangle analysis application. Based on an assumption that the legs are vertical and attached to the bottom of the panel top, i calculated the legs must be 6.97 inches long. This compares favorably with the 8 inches you quoted. t If my assumption is true, the leg length for a 7 degree angle is 2.925 inches. The configuration, if my assumption is correct, will be a right triangle. The hypotenuse (longest leg of the triangle) is the panel length and the vertical legs are the supports. If my assumption is incorrect, edit your question to detail the support /panel configuration. TexMav
- Q:A local air conditioning company is advertising combining their (newly installed) central air conditioning system for homes, with roof solar panels. They say that the combination MAY reduce your electric bill. Nothing I can see to back-up their claims. Hmmmmm. And they offer, if you can get it; central air conditioning that runs on natural gas. Again, possibly cheaper than using electricity.Has any one actually tested to find out if solar panels and/or natural gas DOES, or DOES NOT save you any money to make it worth the bother?
- if you use solar panels it will make electric to run anything you want . it depends how much they charge to build the solar system if it makes sense, money wise. but if your asking if solar power makes enough electric to power an A/C the answer is , you bet your azz .. but only when the sun shines Nellie
- Q:When people buy small solar panels, what are the steps to making it actually charge or run something.. I'm completely new to this of course and im curious. what kinda of wire and other devices are needed and how do you attach the wire and everything..

- Q:Can solar panels be installed on a data center or technology facility?
- Yes, solar panels can be installed on a data center or technology facility. Installing solar panels not only helps reduce the environmental impact of these facilities but also provides a sustainable and renewable source of energy. By harnessing the power of the sun, data centers and technology facilities can offset their electricity consumption and potentially even generate surplus energy. This can contribute to cost savings and a greener, more sustainable operation.
- Q:How do solar panels impact the electric bill?
- Solar panels can significantly reduce or even eliminate the electric bill for homeowners. By generating clean and sustainable energy from sunlight, solar panels can offset the amount of electricity needed from the grid. Excess energy produced by solar panels can be fed back into the grid, earning credits or monetary compensation through net metering. Ultimately, solar panels can lead to substantial savings on the electric bill over time.
- 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.
- What I've heard, is that for those sites implying that you can power your house and save money with homemade solar panels, is that if you try to get your money back, there is no response. Maybe if you used a real credit card, you could dispute the charges through your credit card company. Actually, I wouldn't be worried about buying materials and it not working - the more likely scenario is that you would get their instructions, and realize that they're practically worthless. In Florida, you have a chance to save money on your electric long-term, but it will be by investing maybe $0-20k, and then getting that back after 0 or more years. I'd suggest you contact a local solar installer and get a bid, even if it's only to scope out how much it would cost up front. Then you can shop around and see if you could save by installing it yourself. It's a serious project, not to be taken lightly. It took me about 3 months to put it up. It's possible that you will not save money by self-installing, as professionals may get better prices on the panels. The Florida state rebate is subject to availability of funds, and typically, I've heard people wait a long time to get it. The Federal rebate is a credit to your taxes, so you get it the next year.
