Q:how much power do i need from my solar panels?
Very simple. Look at your bills from the past year and calculate how much power you used and see what you need to cover that usage. How are we supposed to know how much power you use? Maybe you live in a bdrm trailer or a 6000 sg ft house with 20 kids. Oh and remember a few things. There is more to ' going off the grid ' than just solar panels. When the panels work depends a lot on your climate. They kind of suck on cloudy days or if you live in the artic with 6 months of darkness.Also , you need an area for the (not so cheap) storage batteries. Learn to live by cooking with gas or wood as hydro is limited , so is heat. How do you plan on heating your home /water/ refrigerators and freezers? Off the grid means a lot of compromise. Even the amount of time you can spend on the computer asking these questions. You may be limited to no more than hr per day. Off the grid also includes removing any electronic influence. No cell phones , tv (cable/sat) internet. Grow your own food and live off the land. The amount of solar panels you would need to maintain even a current lifestyle as most of us know it would probably require at least /2 acre and the cost would take at least 5-25 yrs to recover. You really need to spend more time into looking at what the cost versus return is. Like I said before. Look at what you use and see what it takes to get that from your panels. You will be shocked. Currently the panels are very good. But they cannot produce what the average home needs per day every day, they are support systems. Much like a fire place. Now they are nice to have and are very efficient. 50 yrs ago you used to toss in 2-3' logs about 6 around into the only heat source in your home. A fireplace. And it sucked more cold air into the house than the heat it produced. History has a way of repeating itself. This stuff was out almost a decade ago, they just didn`t have batteries then
Q:Solar Panels!!???!!!?
Solar Power. There is no denying it, solar power works. Not only is it energy efficient, it is also safe and extremely clean. Whether it may be for a home, business or a community, there are no limits to the energy that the best solar panels are able to offer.It is a guarantee that once this medium is applied, you would easily slash your greenhouse gas emissions and electricity bill.
Q:who knows about tax credits for solar panels?
Congratulations okorder.com/
Q:A more efficient solar panel?
yes it is being done. i've seen adds for such a system. on the other hand, if you had a 5 sq in Lens focused on a small cell, and a 5 sq in cell, they'd be about the same. in fact, the cell might be a bit better because (A) there wouldn't be any loss in the Lens, and (B) it might be that the solar cell would use some frequencies to which the Lens was opaque. in addition, the cost of solar cells is dropping, making the cost of the mirrors or lenses uneconomical by comparison.
Q:How energy-productive are solar panels, compared to natural gas?
Solar panels are not nearly as energy productive as natural gas. Case in point how many natural gas fired calculators do you have on your desk? or how many solar fired fireplaces do you know of? Solar panels are a great complement to natural gas/fossil fuel burning sources of fuel though. The more energy you consume from renewable sources of energy (i.e solar, wind, etc) the less you are consuming from non-renewable sources such as natural gas. Solar panel's rate of producing electricity depends on many different variables. Are the panels in direct sunlight? (with no trees or shrubs blocking the panels) There are panels out there made by Kyocera for example that are 85 watts, 65 watts, 50 watts. You should talk with a Professional about this. Look into Sun Electronics as I know that their website has a solar calculator and other helpful tools for interested parties. Good Luck
Q:can I connect my pool pump to a solar panel?
You will need several panels and it will be expensive.. That's if you are running your pump for 4 hours each day.. You will really need a battery bank to give you Amps and or Watts.. The motor when starting will need up to 5 amps at once if not more... Too much for a solar panel by it's self and even 4.. maybe five would do it At watt per solar panel.. I am not a genius on this issue but there are base lines..
Q:What do I need to do to run my dehumidifier from solar panels?
This Site Might Help You. RE: What do I need to do to run my dehumidifier from solar panels? First of all is it possible? I do not know how much electricity my dehumidifier but could someone give me an idea of how much this would cost to do? A link to a solar panel or equipment that would do the job would be nice too. Thanks in advance.
Q:Solar Power...........?
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:where do you get little solar panels?
You could build them yourself? Depending on the time you have.... They are having a special at the moment....
