Product Description:

1. Structure of  Polycrystalline Silicon Solar Modules 60Cell-240W Description

Solar panel refers either to a photovoltaics (PV) module, a solar hot water panel, or to a set of solar photovoltaics modules electrically

connected and mounted on a supporting structure. A PV module is a packaged, connected assembly of solar cells. Solar panels can be

used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Each

module is rated by its DC output power under standard test conditions, and typically ranges from 100 to 320 watts. The efficiency of a

module determines the area of a module given the same rated output – an 8% efficient 230 watt module will have twice the area of a 16%

efficient 230 watt module. There are a few solar panels available that are exceeding 19% efficiency.

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:How much maintenance do solar panels require?
New solar panels are clean and shiny and they look cool. Then they get dirty with dust and debris caught on the wind and residues left behind by rain and birds. Solar panels must be regularly cleaned and maintained in order to keep them operating efficiently and maximize the amount of sunlight they convert into electricity. Unlike windows your solar system needs to have a clean and clear surface to ensure they are working at their maximum efficiency. If they are not at their optimum performance it means they are not producing the amount of electricity that they could be. Solar panels will attract dirt, dust, soot, pollen, tree sap and salt crystals in coastal regions creating a fine layer of grime. This layer reduces the amount of light reaching the silicon cells under the glass surface and reduces the panel's effectiveness. A solar panel that has never been cleaned could be producing almost a third less power than it otherwise could be. Some have reported a ten to fifteen percent loss of solar output due to dirty panels. From the ground the panels may appear to be clean, just like your windows. Up close however you can see the grime that has built up from the dirt and pollution in the air. A more noticeable deposit that can be left on panels is bird droppings. These tend to completely block the light from areas of the photovoltaic panel and can considerable reduce its effectiveness. See much more about solar panels maintenance below link
Q:The effect of colored light on a solar panel?
It is based on what the solar panel is made out of. Many of them will generate electric into the NIR region.
Q:How many solar panels would I need to power my washer machine?
P(Watts) = I(Amps) x V(Volts) Power = 9.6 x 20 Power = ,52 Watts. Therefore you would require 6 x 208Watt solar panels to power the machine on a clear bright day, many more on a cloudy or dull day. Sorry to be a little rain cloud!
Q:What are your opinions on solar energy?
I have had my system for almost a year and love it. I got a 3.74 kwh/dc system, my highest electric bill was $35 in the dead of winter and last month was $6.. I paid $6K for the system and was told I would break even in my 6th year, that was factoring in a 5% annual rate increase. In my area the last few rate increased have been well over 5% and they are talking up to 2% next year. Just keep in mind the amount of energy you use will determine how large of a system will work best for you. My system is tied to the grid, so I don't need a storage system. My utility has net metering, so I sell them my excess during the day and buy back what I need at night.
Q:Solar Panel watts needed?
With you up to solar panel, then things go downhill. Your Water pump will be rated at gal/hr but how about the air pump? 600watt LED? What you need to know in order to select your solar panel is how much current you will be draining. You can work this out if you know how much power and how long they need to run. Please, a bit more information (that is relevant!).
Q:DIY home solar panels?

Q:Photodiode vs solar panels?
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:Solar panel question
Hi, okorder.com/ having good batteries like this one make save you the hassel to buy controllers. You can control your own charge buy different tips
Q:Solar Panel Help, Trying to go green.?
Ideally, you should not be trying to run individual appliances off of a solar panel. What you should be doing is selling the power harvested from these panels back to the power company as a savings from your power bill. Here in southern California I have heard of people actually receiving monthly checks from the power companies.
