Q:solar panels and wind power help?
Both wind and solar take many years to break even economically, even with government subsidies (Using someones hard-earned tax dollars for your use). If purchased and installed with your own money, they will never pay for themselves because they will need replacement long before you save enough to pay the cost.
Q:What are the limits of solar panels?
I believe solar panels gather enough energy from the sun in the daytime.I don't own one therefore I AM not a 00% sure unless it runs on batteries,generator or alternator.Who knows it just may plug up at night.
Q:how many solar panels needed for Heater and AC?
There are many, upon many variations of equipment needed for a complete solar home. I would call several contractors in your area that deals with it and get estimates. You have to look at what your wattage diet is at your home. How many watts are you using for your AC and heat. Which can vary by age, efficiency, insulation of home, etc. Look at your electric bill for a normal summer month and a normal winter month, then estimate your heating and cooling (Sometimes can be as much as 70% of the bill). You will see on your bill your toal kilowatt hours. ( Kilowat = 000 Watts) Solar systems can start as low as $2.00/watt, but can rapidly approach $20.00/watt depending on the difficulty of application etc.... Here is the great thing, in many areas of the country there may be rebates from the county or state. And what you don't use can be fed back into the grid, and you get paid for it. But as always - Call a quailified contractor and get the right system for your home.
Q:How many LED's can I hook up to my mini-solar panel?
Typically LED's run off low voltage and 20mA or so of power (it depends what kind of led you have). That being said if one of your solar panels only provides 22mA of power then your circuit would have to be a series circuit for you to connect more than one. In a series circuit the current supplied of 22mA will go through each LED whereas a parallel circuit the current would be divided for each subsequential led. So in your case i can see you getting away with 3 or so led's before the voltage drop across each led will cause the voltage to be insufficient enough to drive anymore. Keep in mind the LED's will turn on but the first one will be bright then next one not as bright and so on. If you opted out and bought a solar panel with 200mA and 4V you could wire the led's in parallel and get 0 led's to turn on with the same brightness or intensity. Hoped that helped!
Q:energy and solar panels?
It depends on the size of the solar panels and the intensity of the solar-light. So, there's difference in every place. It's impossible to answer unless there's detail of panel size, panel quantities, average rainfall, average solar days, etc.
Q:Anyone here have residential solar panels?
Check out what someone did in Oakley, California - Contra Costa Times 22 June 2007 Going Solar Can Pay Off On The Long Run PGE Electric Power Monthly Bill Before Solar = $,200. Home: 2,900 sq. ft. Installation Cost for 6.7 Kilowatt 36-solar cells $46,000 (minus $7,60 State rebate). New Resources Bank, a “green” bank in San Francisco, lend them a, no-fee, no-points, second mortgage at $200 a month less than their previous monthly payments because of their plan to install solar panels. PGE Current Electricity Monthly Bill After Solar = $7.63 after deductions for any excess power produced by solar cell which PGE.is legally required to buy. PGE has not build any new electric power plants in California for years and their profits do not depend on sales volume, Sen. Feinstein introduced a bill to make this a National Law. Poweful interests are against this, perhaps they are foreign companies that hate Americans? Surely, they are not bona fide, red blooded Americans that love all the people in the U. S. of America, you think?
Q:Solar panel trouble?
Most solar panels convert the energy collect from the sun directly into usable DC current. So no, you do not need a capacitor to test a light if you are in sunlight. You will need a capacitor or rechargeable battery if you plan on testing the solar panel away from a light source after the capacitor or battery has charged. Solar panels cannot store electricity.
Q:Does anyone know a company that will make custom solar panels?
Make okorder.com
Q:Good Idea To Install A Solar Power Energy On A Restaurant?
Different solar companies install these panels. Check your local area for a free quote. If you don't already have a solar panels for a hot water system yet, consider a thermosiphon design, then you need no electricity to produce hot water. All the other designs require some electricity.
Q:Will my off the shelf deep cycle battery I purchased at autozone work well with solar panels?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
