Q:I want to know how to hook up a Solartech SPM020P-R, 20W Solar Panel to a single outlet that you can but at a store.: That solar panel puts out about amp (in round numbers). If you are talking about a 20vac outlet, you'll have to send the output of the solar panel through an inverter. That brings it up to 20vac. 20 watts at 20 volts means you'll only be able to draw 0.6667 amps. With an inverter at 85% efficiency, you'll only get about 0.4 amps. That would barely light a CFL. 20 watts of power at 7 volts = amp (in round numbers) 20 watts of power at 20vac = 0.6667 amp (in round numbers) Power (watts) = current x voltage. If you increase voltate, you must decrease current to get the same watts. Watts is the common denominator in power measurement.

Q:How do solar panels affect the aesthetics of a building?: Solar panels can have both positive and negative effects on the aesthetics of a building. On one hand, solar panels can enhance the visual appeal of a structure, adding a modern and sustainable element to its design. They can be integrated seamlessly into the architecture, creating a sleek and futuristic look. On the other hand, some people may find solar panels visually unappealing, especially if they are not well-integrated or if they cover a significant portion of the building's surface. Ultimately, the overall impact on aesthetics depends on the design, placement, and integration of the solar panels.

Q:What would it take to make a heater for a small solar panel. I am looking into making a heater for a livestock tank to keep ice melted. I know that heaters take alot of energy to run, but my theory is that if heated mirrors on a car can melt ice with low voltage and im sure not extreme heat (40-60 degrees) then making a heater with just high enough temperature to keep from icing over and melting ice is possible. Where do I start? I would like to use an inexpensive solar panel that will generate enough heat to keep ice from forming and melt it at the beginning of the day. How can you make such a heater and apply Ohms law so that it will function correctly, what Wattage will the pannel need to produce to generate enough heat for the heater. The device will only have to be large enough to melt a spot large enough for an animal to drink.: Homemade okorder

Q:Can anyone give me a link to a website that sells really big solar panels? Enough to run a small cafe on entirely solar power.: Just google search solar panels or pv panels and you should get a long list of them. That's what I did. Most of the sites selling them will also have the inverters etc that you'll need. Most likely you'll put several small or medium sized panels on your roof - as opposed to just one large one. You probably won't be able to run an entire cafe off of photovoltaic panels, even if you have a bank of batteries. Too many appliances running at the same time. Ask your electric utility company about net metering - you'll buy juice from them when your demand is high and sell to them when your demand is low - IF you can find a sunny day when you're not using juice, but if you have a restaraunt-sized refrigerator you probably won't be selling as much as you're buying. In effect, it won't eliminate your elec bill, just make it a bit smaller. Either way, you may be looking at spending $20,000 to cover the roof with PV panels and your savings won't pay that back any time soon. So, PV is not so great for a business. Much better for a home where you'll be at work all day the only appliances running in your house is your frig. Whatever you invest to solar your house will be repaid when you sell it, meanwhile you'll reduce your bills dramatically, especially if you convert all your indoor lighting to LEDs. On the other hand, the Googleplex, Google's office building full of computers, covered their roof with pv panels and claim to have reduced their monthly bill by /3. BUT, that's a huge building with lots of roof space.

Q:What controllers and all that stuff do I need for these solar panels. Oh and the the batteries will be rigged up to a big electric motor so please leave information on how to wire the batteries to the motor...THANKS!!! 0 POINTS!: Many solar panels wired in parallel, 2 volt solar regulator, 2 volt battery e.g. 30 Ah, 240 volt inverter, autotransformer that can go down to 50 volts. There are many parameter to the electric motor missing. AC or DC, current needs for full load. How many watts the motor uses and the number of hours required will influence the solar panel, regulator and inverter specifications.

Q:I found portable solar panels used for boats etc. and was wondering how I could effectly use them for my home instead. If you have used them in the past, please tell how they worked (good or bad).: well i highly dout that solar panels ued for boats and rvs will work the same for your house, because your house requires more energy to run then a solar power can give.

Q:Can solar panels be damaged by hail or strong winds?: Yes, solar panels can be damaged by hail or strong winds. Hailstones can cause cracks or fractures in the glass surface of the panels, affecting their efficiency. Additionally, strong winds can potentially dislodge or break the panels if they are not properly installed or secured.

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.: I'm in the California Foothills and the island of Mindanao... I have both solar panels (electric and water heating) and a single wind-generator since 2000. We actually sell power to PGE in California and are self-sufficient in Mindanao. NOW, I'm confused with YOUR math... you say the Rep. suggests a monthly savings of $35 (25% of $40) which would be $420 / year. If materials / installation are $8,000 less $2000 tax-credit: it would take 35 years to pay off $6,000 at $420 / year. 980 Kwh/ mo is some pretty heavy usage... I'd suggest trying to reduce that. CFT's, lowering your AC setting, no lights if NOT in room, un-plugging stand-by appliances, and upgrading insulation. At our 2000 sq ft California RANCH we only burn 400 Kwh per month, and that includes an 800 sq ft barn (admittedly we heat with a wood-stove). We have 5, Sanyo 200 watt panels (3kw total) and generate an avg 900 kwh / month. SO, we're selling BACK almost 500 kwh mo. to the grid on the photo-cells alone. The kw wind generator averages another 20 kwh / month. I THINK the company YOU are working with is selling the EXCESS electrical-power back to the power-company behind your back !! GOOD LUCK

Q:I have a question about solar panels. What are the benefits of this system if I installed in my home. for example i know it produces electricity but does it do anything else? How many panel would you guys think I would need for 2000 sq ft. do you know if it produces hot water? Thanks for your help: First, solar panels come in two basic types - photovoltaics, which produce electricity (the black cells you normally think of), and solar thermal, which heats water (or some other fluid). It's one or the other, you could install both if you want that. Solar thermal is cost effective today, depending on how you currently heat your water. (The hot water could also be used to create electricity, like in a steam turbine, generally done in larger power plants). Photovoltaics are more expensive, but coming down in price every day. To know how many panels you need, you first have to determine how many kWH your house uses, and do you want to be completely off the grid (which would also require large batteries), or just reduce your electric bill.

Q:can a small solar panel be charged with lamps?: yes, although charged is the wrong term. But for every 00 watts you put into the lamps, you will get well less than 0 watts out of the solar array. Well less. .
