- Q:Can anyone give me some info on how to figure how many panels needed for a 0 volt 2 amp pool motor. Thanks/ Run 5 hours a day
- You okorder /
- Q:I've been reading up on Solar panels because I think in the long run this would be beneficial in the long run. My Dad had looked into it before passing and had said it was too expensive. How much does it range for getting them placed on the roof and how exactly does that work? I think I remember being told that PGE has incentives and could possibly even end up paying you for having it? What does having panels cover? I know electricity but does it also heat things up? Sorry I'm kinda dee dee dee on this lol. Any and all information would be greatly appreciated. If anyone has solar panels can I get your experiences with them? Thanks!!
- There's a few different kinds of solar panels. Some of them are only for collecting heat, they're relatively inexpensive and not a bad deal, though installation can be expensive of course. The most sophisticated of these use some pretty high tech collectors to heat up an antifreeze solution that in turn is circulated through a reservoir (how water heater), to supply the house. Your electric producing solar panels are more expensive. You can go on OKorder and do a search on photovoltaic panels and get a pretty good idea real quick. The panels alone can run you 2 or 3 bucks a watt of output or more, and you may need 3 or 4 thousand watts of output to give you reasonable system for your house, depending on how much electricity you use. Then there's installation, for which you may need a professional electrician and so on. If you want a system incorporating deep cycle batteries then that's another expense, but you don't necessarily need those if you're not planning to take yourself completely off the grid. Not that the systems are really complicated. Some people wire panels together themselves from scrap cell components to save money. Of course you'd need to understand the basic wiring involved for that, and you'd almost certainly be required to retain an electrician to tie any system into the grid itself. Although there is such a thing as a plug in grid tie inverter. This is is a gadget that will take your DC solar panel output and feed it into the standard wiring of your house via an ordinary electrical outlet. You'd still need to understand enough to get the DC voltage right no doubt.
- Q:I am in the market for buying a home. There is one for salke that actually has solar panels on top. How are they used? Do you need to pay for gas and electric still. Does it really light up the house and keep it warm. WHat about the AC keeping hte house cool in the summer does it work for that too? Please explain in solar for dummy terms. I haveno clue about solar panels other thatn the fact that it needs sunlight to run.
- I think that rustoria67 bumped his head on some thing. There are thousands of homes using only solar panels to power their homes, and it no way near an acre of them. With the right setup Kw of panels will work. Remember one can't bring a boat to an airplane race and hope to win. Look at this link.
- Q:I live in a higher LATITUDE so in the winter months, there is a limitation in the amount of sunlight available, but will this impediment restrict the ability of solar panels to function due to the lack of sunlight involved?
- Solar panels generate power only during sunshine hours. But they only need sunshine, they don't like the heat, that comes along with the sunshine. So its a trade off, the places that have a lot of sun, also have a lot of heat, and places that do not have a lot of sun are not that hot. But you do need sunlight to run solar panels. There's a lot of tools available which can tell you how much power you are able to generate given your location.
- Q:. Does it really only cost $200 in contrast to $5000 or more?2. How much would it cost to build panels that would energize an entire average household? (washer, dryer, water heater, lights, fans, a/c)3. Is there a place to get the info on how to make them for free instead of paying E4E?4. Are the professional solar panels better? more efficient? 5. Will the electric company in So. Cal. really pay you?6. Do you have to be certified to do this professionally? or an electrician? If so what schools teach it?7. Would wind generators be of any use in So. Cal.? I mean don't you really need to get the fan spinning to get energy?8. Are there any extra unseen costs? (tools, energy converter, ect)9. How much is it to get an electrician to hook you to the grid?0. Is it better to hook to batteries or the grid? Pros, cons, why?
- I believe Earth4Energy to be a bald-faced scam, selling plans that will not do what is implied in the marketing, and imparting no information that is not publicly available on the internet, already. If you were to search for solar panel on torrent sites, most likely, some disgruntled customer has posted the material. It probably violates the E4E copyright, so I'm not suggesting that you get it in this manner. I'm going to skip many of your questions, given my already-stated opinion of Earth4Energy. Professionally-installed panels have a net cost of thousands of dollars in general. While they can save money (and Southern Cal is an ideal place for this), consider that it generally takes 0 years or more to get your money back. If you're on S Cal Edison, or SD Gas and Electric, you can go on net metering. They don't really pay you, they credit your electric bill. After a year, if you used more electricity than you generated, you pay them. If you generated more than you used, they reset the balance to zero and say thanks for your donation. You never really get a check, like in some other states. But you should have lower electric bills. You can put up panels for your own use without any certification. To put up panels professionally, you'll need a C-0 contractor's license from the state, or will need to be under the supervision of someone with such a license. But if it's the latter, you might just be the grunt that carries the panels off the truck and up the ladder, for minimum wage. I'd say better than 95% of residentail solar is connected to the grid, if the grid is available. It's a clear winner. Who wants to pay 50% more for their system, just to have batteries that need their water and acid checked all the time? Below is one of many unsatisfied customers from Earth4Energy. Be careful in your search, people selling these reports have bought up the keywords such as scam and ripoff to direct you back to sites selling the product.
- Q:I have seen DIY software which explains everything for novices. Specifically, how to build your own solar panels and tie them into your home electrical system for about $00 in parts.Has anyone tried doing this? Was it easy?
- Hi Mitch, Yes they are legitimate ans so much so the government will actually help you pay for them. Someone has already mentioned if you purchase them from your local solar panel installer they will not be cheap.They have come down in price a lot over the last couple of years. Yes you can build your own and no its not too difficult.You need to know in your own mind whether you just want to reduce your utility bill or come off the grid completly. The best solution is a combination of wind and solar power and yes you can build your own windmill as well and at the bottom her I will show you where to go to get easy non technical plans. Naturally the sun does not shine at night so your solar panels would not work then but windmills function 24/7 as long as there is wind. If you have nearby neigbours please be aware windmills do make some noise which might upset your neighbours and of course see if you need planning permission from the town. The solar panel plans show you how to set an 80w solar panel which of course would not be able to power your whole house,but once you have built one why not build loads more and each one will get easier to build. Wish you all the best.
- Silicon, simular to aluminum foil. When assembled correctly will produce electricity. This is a prosition process to construct. Check out DIY sites on the internet. I hope this was helpful?
- Q:Can I use a regulator from a car to regulate the voltage from a solar panel to a battery?
- solar panels will naturally produce a certain DC voltage which is what your battery needs - the current will vary based on the sun light. You need probably 4V to have some over voltage. So based on your specs look at having at least 4 V but not too much over that (tells you how many panels you need in series) I would have blocking diodes (probably the solar cell has them built in) to insure the battery does not discharge thru the panel.
- Q:are solar panels just a photodiode?A Photodiode converts light into either current or voltage? Right?
- yes. Any semiconductor junction will convert light into electrical energy, just shine a light at an LED (connect LED to voltmeter) and you'll see a small voltage produced (if you configure the meter as an ammeter it will develop a very small current). Solar panels are just VERY large surface photodiodes.
- Q:can anyone help me? i was thinking of installing solar panels to cut bills but would it be a waste considering its gonna need a circulating pump running almost 24/7 (which will use electricity) and even still will only provide me with quot;warmwater? also would it be possible to install the solar panels for the sole purpose of providing sufficient power to run electric heaters instead of using gas/oil? this way allowing me to have a warm house without the expensive bills. brobably talking about running 7 heaters/electric radiators.
- A thermal solar panel to feed your water heater is the most efficient. But you need a classic heater system too when there is no or little sun. Solar panels to heat a home is not at all recommended. First of all, you get less day light and less sun in winter, so you won't get much electricity. They work best in summer, but electric panels have poor yields and are a very long term investment. You will need to wait years before saving money. Natural gas, a well isolated home, and a good old sweater is the best way to cut bills.
