Q: I'm from Toledo, OH about 2 miles from the MI line. We are a foster family and have adopted 5 children. We just moved into a 5400+sq 2 story home. We have (3) 2.5-3 ton AC units to cool this huge house. We got the house cheap...$75k couldn't pass it up! Anyway...I was wondering how many solar panels it would take and of what wattage to power these Central Air Units and maybe the rest of the house. We have 3 people in our home......9 of which are children who leave the lights on and run hot water to beat the band. We have all brand new energy star appliances and front loader washer and dryer. Gas Range and Gas hot water tank. Was thinking of using metal window frames and buying solar cells and making my own panels. Just don't know how much to buy. We face south with no trees. Constant Sun. thanks for your help. An e-mail address to bounce questions off of would be helpful if you experienced. tx.
With your load, the largest system on the page I reference above would not power your entire house, if all the AC units are running. However, how often does that really happen? You need to look at your utility bill and find your actual amoutn of KW hours of electricity used in a year and you hav enot told us that. The base price of top system quoted here without incentives is over $70,000. As you can see, the lions share of incentives is the utility company followed by federal. I have no idea if your local utility company offers incentives or not. You would have to resolve that with them. However, the federal incentives are still there even if your state and local utility has none. However, the price to you goes way up without all of these incentives. And your idea of using windows to mount solar cells is totally impractical. Yes, I know there are web sites that advertize just that, but it is total BS. The first word of advice to anyone looking to do this sort of thing is to FIRST have a complete energy audit done and then do whatever they say to conserve as much energy as possible, thereby reducing your need for solar power. Only then should you look at using solar to cover part of your load. We are a foster family and have adopted 5 children< WOW! I would like to thank you for what you do.
Q: Can solar panels be used during a power outage?
No, solar panels cannot be used during a power outage unless there is a battery backup system in place.
Q: Can I fet free solar panels. This site okorder sells a book that tells how to, but I ordered tha book more then a year a go, and in never came. I even sent them a email a day for more then 3 months and never heard back from them. If anyone knows how to get free pannels, please let me know how. A $300.00 a month bill is slowly killing me.
If you sent payment via the US mail, report them for fraud. Next, solar panels usually have a high upfront cost for the homeowner - but this is usually offset by a tax refund. The amount of refund varies by area. Check out the cost with a local installer - they have the most motivation to know all the tax breaks you can get. Then save for it, and in the mean time switch your bulbs to fluorescents, unplug your coffee pot, computer, VCR, microwave when off, and see if your energy company provides free insulation evaluation services. And reduce your temperature this winter by 2 degrees, and change that furnace filter.
Q: Hello from SO TX.. I would like to know if anyone out there has SOLAR PANELS on their home?I have a 850 sq ft. house. I called Austin to a company that offers panels and installation. The cost $8,000.00, for 0 panels . The rep said we would save about 2 to 25% on our electric bill /mo. We use approximately 980 kw/mo. Our bill is around $40.00 / mo...I really don't think that's a good enough savings. We figure it would take 25 years to recoup our investment.And where we live in TX it does not offer any incentives. The gov. allows you a $2000.00 tx break.
Be glad you didn't buy. The current products are dinosaurs, 50 year old over priced tech. Don't lose hope though. The thin film tech is just now starting production. It's not yet available to the general public ( production for the next year is already sold out), but will be in the near future as production capacity increases. It should drop prices to about /4 of the current price, and your recoup time will be about 7 years. Go ahead and research thin film solar, and be thankful you didn't buy a product the government has to pay you to buy.
Q: The average solar panel produces 0% of the energy that is put into it. What is happening to the other 90%? Is it being reflected or is it being obsorbed by materials that are not a part of the solar cell? Is it possible to one day have near 00% efficient solar cell technology?
intense frequency waves alongside with x-ray or UV are additionally particularly intense lively while in comparison with the soak up-ale wavelength (which i think is many times infra-pink). so if we are able to make panels that soak up those wavelength rather of the warmth of infra-pink waves, we'd in all danger be getting a lots larger performance than 0%. desire it helped
Q: Do solar panels require cleaning?
Yes, solar panels do require cleaning to maintain their efficiency. Dust, dirt, bird droppings, and other debris can accumulate on the surface of the panels, blocking sunlight and reducing their ability to generate electricity. Regular cleaning helps ensure optimal performance and maximizes the energy output of solar panels.
Q: How can I know the right type of solar panel to choose for my small village house in Africa?
The power output of a solar panel uses a formula to determine kilowatts produced per hour per square meter per day. This calculation is important because, if you plan to install a solar power system for your home, you will want to know how many solar panels will be needed. To calculate solar power requirements correctly, you need to gather the data that is needed for the calculation. First you have to find the average amount of solar radiation available for your area. You can use a solar radiation chart. This can range from a 4 to a 7 depending on the area you live in. Write the number down on a piece of paper and indicate it with the letters RA. Next is determine the amount of electricity that you use daily. Add the kilowatt-hours used per month from your utility bill. Multiply this number by ,000 to get the watt hours in a month. Divide the total by 30 for the amount of electricity you use daily. Write this number down and indicate it with the letters DE. Determine the percentage of your home that you want to power with the solar power system. Write this number down and indicate it with the letter P. Determine the system inefficiency factor for the solar power system. You should be able to find this on the brochure for the system or from the manufacturer's web site. Write this number down and indicate it by the letter I. Determine the power or yield that is required for your home. Use the equation P = I x (DE x P) / RA to find the power requirements in kWh. Divide the number from Step 5 by the peak wattage for a single solar panel to determine the number of panels you will need for your home. Goodluck! :)
Q: solar panels are way too expensive to buy, can they be homemade cheaply? i want at least 500 watts. everyone on the web sells these instructions, but i'd like a link to free info, if it is really possible for a non-sciencey person to make. thank you
we can walk you threw the process. Materials you will need… A sheet of copper flashing from the hardware store. This normally costs about $5.00 per square foot. We will need about half a square foot. Two alligator clip leads. A sensitive micro-ammeter that can read currents between 0 50 microamperes. Radio Shack sells small LCD multimeters that will do, but I used a small surplus meter with a needle. An electric stove.
Q: I am planning to run a couple of dc motors on solar current. I have a couple of 450mA 4V, 200mA .5V, 00mA 9V solar panels with me. I need to run a pair of .5A 9V motors. Suggest me a circuit along with other equipments I might require. For your info, I am trying to build a solar powered drone / UAV
I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
Q: Can solar panels be installed in areas with high levels of saltwater exposure?
Yes, solar panels can be installed in areas with high levels of saltwater exposure. However, it is important to choose solar panels that are specifically designed to withstand such conditions. These panels are typically made with corrosion-resistant materials and undergo rigorous testing to ensure durability in marine environments. Regular maintenance and cleaning may also be required to prevent salt buildup and optimize performance.
