Q:how do you make solar panel?
well... I'm not sure how you can make a solar panel that you can store electricity off of. But a simple solar panel is... Take a pane of class a bunch of pop cans and a fan... color the bottoms of the pop cans black and attach them to a board of some sort (black side up) put the pane of glass over the cans (with about 5 inches of space between) and put the fan blowing away from the cans you can set this in a window that gets lots of sun and it will use the solar energy to heat your house (its pretty efficient and warm)
Q:Solar panels with snow?
If you have an electrical backup you could install something to melt the show where the solar panels are installed. You might try installing them near a fireplace chimney if you have one. My thinking tells me if you have a clear raised bubble or pyramid over the panels it might help.
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-Cell-panel help please?
I hope this will help you choose your charge controller / battery charger more effectively. Good luck!
Q:Solar panel setup?
I okorder.com/ for excellent inspirational info within my blog to help not only our world and its creatures, but to also open peoples hearts and minds to many amazing wonders that life has to offer. I also have lots of info in my blog to help fuel peoples imaginations to many possibilities that can be found only in the minds eye. Along with lots of environmental info, amazing environmental pictures and videos (These videos show the beauty of this world and what life can be like if people take the time to appreciate life’s true beauty). Let us all strive for a greener/brighter future by helping to create a solid foundation for future generations to build upon, so we can hand them a beautiful world, filled with never ending awe and wonders!! Where peoples differences and uniqueness are accepted, where we all live as one, helping one another so that we can all play our own mysteriously beautiful melodies in the never ending, awe inspiring, song of life :-) I truly have faith in humanity and believe that someday our lives and the world in which we live will truly be transformed for the better.
Q:rooftop pool solar panel leaks?
This Site Might Help You. RE: rooftop pool solar panel leaks? Rooftop solar panel (not sure if rubber or plastic?) has leak arising from thin vertical crack in panel about long. Any ideas for repair? Thanks.
Q:how many solar panels do I need for my house if in average i consume 880 kwh?
First, okorder.com/... Second, as a general rule of thumb, you can generate at most 00 watts of power (.Kwh) per 2 square feet of roof space. I have had to revise my own estimates after building a solar array in my yard using high grade solar panels. Solar panels do not put out their peak rating all the time. NOTE: I am not paid nor given any compensation by solar interests.
Q:what are bad things about solar panels?
. Expen$ive. 2. Must be large to generate much useful energy 3. Don't work in the dark 4. Lose efficiency if not kept clean 5. Lose efficiency in less than full sunlight 6. STILL don't satisfy the tree huggers...they delayed a solar panel farm out west for years to wait on an environmental impact study of the land beneath the panels.
Q:how do solar photovoltaic panels work?
Hey E Girl, photovoltiac panels are pretty simple. They start with a solid block of silicone, and shave thin layers off of them, called wafers. Once you have about 72 of them, you take half of them and dope them with boron, then the other half are doped with phosphorous. Once that's done, they take one each phosphorous and boron wafer, and glue them together with a special conductive epoxy glue, and attach a wire to each wafer. When the two glued wafers are exposed to the sun, a reaction occurs that forces free electrons from the silicone particles from one wafer onto the other, and a voltage is generated between them, about /2 volt to be exact. Once all 36 pairs are glued together, they are wired in series, connecting the phosphourous wafer from one to the boron wafer on the next, and so on. If you start with 72 wafers, you'll have 36 pairs glued together when you are done. At /2 volt each, that makes a 8 volt panel, which is used to charge a 2 volt battery. The charging source always has to have a few more volts than the battery. These 36 pairs of cells are then arranged on some kind of back board, glued down, covered with acrylic glass and mounted in a frame. There are some great websites you can go to for more info, I will list some below. Did you know that there are over 00,000 homes and businesses in the US alone that use some level of solar power to operate their electrical systems? That's good news. We actually live in one of those homes, it is powered by both the wind and sun and heated with solar and wood. I hope this answers your question, good luck, and take care, Rudydoo
Q:How effective are solar panels now in N E with our 40+ snowfall this month?
Just okorder.com/... As an aside the efficiency of the panels will also be maintained if the panels are cleaned of dust and debris. The maintenance of removing snow and dust is one argument for having the panels on a rack on the ground. Solar Thermal panels are intended to capture the sun's heat. Two types that make hot water are flat panels and vacuum tube collectors. The vacuum tube collectors work better in colder and cloudy areas but their efficiency prevents heat loss that might melt snow. Most of a light snow will fall between them but you are back to maintenance with a heavier snow. Flat panels are less efficient and will melt a light snow off of the panels for a heavier snow you will need the roof rake. The last type of solar panel are solar air panels. These are most often mounted on the side of a house rather than the roof as they are intended to provide hot air to the living spaces. They are essentially like little greenhouses. Unless the snow is building up against the side of the house these should be free from a snow problem.
