Q:How to connect or use Solar Power Panels?
You will need help with this. Panels may or may not be 24 volt. If you can find a name tag, you can find out from the manufacturer's web site. Some folks hook them all in parallel. Mine are in series, to create 480 volts. the reason for going to higher voltage is to reduce power loss in the wiring. Even then, I used a wire size larger than recommended. The frames want to be interconnected, and wired to ground. The live conductors connect through disconnect switches to an inverter. The inverter is sized to the output of the panels. Where the utility allows net metering, the inverters are connected through a disconnect switch to the grid, which of course also feeds the house. Assuming you are on the grid, you will not need batteries. If outages severely impact you, you can have batteries. Counting against them is that they are costly, and use part of the power you generate, just to keep them charged. If you have batteries, it is usually best to rewire circuits so noncritical circuits are disconnected during outages. Leaving perhaps minimal lighting, fridge, freezer and critical medical circuits. Learn all you can from the Internet (try solar panels), and from the green search box above. Be sure to see if your state has a rebate program, and the conditions which it requires.
Q:solar panels and how they work
There is a variety of information available on the internet regarding solar panels. You didn't say if you were interested in installing a photo-voltaic system to generate electricity, or if you wanted a passive solar system. From what I've read, the method that would give you the greatest payback for your investment is the passive solar heater. I can't give you exact instructions on how to construct one of these units, but there are many websites with instructions. My older brother had one of these mounted on his old farmhouse. He said his furnace didn't run all day during the cold Wisconsin winters. The government rebates or tax credits are usually a one time deal. They may pay for part of your installation, but they won't cover the whole cost. The only thing I've heard of that will pay you every year is a wind generator tied into the electric grid, but thats another posting. I'm including a link to a site that will show you how to build a cheap solar heater that you can try yourself.
Q:Why are solar panels effected by operating temperature?
Absolutely temperature matters. So what do higher temperatures do to solar photovoltaic panels? As temperatures rise, the efficiency of solar panels decreases. Heat causes electrical resistance to the flow of electrons. On days where the temperature is more than 75 degrees, the electrical resistance makes the voltage fall thereby producing less kilowatts per hour. Your roof is much hotter than temperatures on the ground. That’s why solar panels are not mounted flat to a roof. There’s usually a few inches of spaces between the panels and roof so air flow can easily pass through and cool the panels down. There are some photovoltaic panels that are designed specifically to operate in hotter temperatures. These panels have a higher temperature coefficient. This is especially important in high heat climates like Arizona or New Mexico, but probably wouldn’t make too much of a difference in New England (except maybe this year). If someone lives in one of these areas, they should speak to a solar installer to make sure they are using they right equipment for their region. Please note: Solar thermal panels used to heat water can withstand high temperatures without any degradation. In fact, hotter temperatures would actually be better for these types of modules.
Q:how to store energy from solar panels?
I have no idea what you are doing or what you think you are accomplishing. A 235 watt panel isn't much energy. You can certainly store it with a plain old lead acid battery.
Q:260 watt solar panels on an rv?
There are many other controllers, you just need to get a sense for the limitations and make sure you are working within them. Controllers are not that hard to hook up, two connections simply go to the battery, plus and minus. Then the other two go to your panel. I like to put a switch at the panel output, leave it off while you are hooking up the panel side wiring of the controller, then when you are sure everything is connected properly, and you have some kind of battery power indicatioon at the controller, throw on the panel switch and see if it is charging. Remember that a panel is a power source, and connecting it to the controller while it is in the sun is like hooking up a car headlight while the lights are turned on. Another option is to wrap the panel in a blanket and put it in the shade while you are connecting it up. Your panel has a max amp rating, Imax, which will likely be around 5 or 6 amps at that voltage and wattage. Number 4 romex will work for that, as well as medium duty AC extension cord wire, if your run is less than 30 feet or so. Take care Steven, Rudydoo
Q:Im a bit confused about what a solar panel is?
A two KW system would be made up of a number of solar panels. Panels used in residential and commercial systems usually run in the range 50 watts to about 200 watts. There is a HUGE amount of information available on the internet about solar panels and all the components of solar electric systems. All you have to do is search on the internet under solar panel. It's very safe and easy. So just do it.
Q:Opinions on Solar Panels?
Bing solar power in Germany. Solar power has an option of assisting in removing some of the burden during daylight, from power generation plants. Anything is a help. Plus they will continue to do it forever (at least a lifetime). But they are not the total answer. Like wind, limited to certain areas. Wave generation is another solution, but still limited to coastal areas. The current design of most supply grids does not allow transportation of power long distances. You want a real eye opener, Bing transportation line looses power grid and see how much energy is wasted, and the amount of carbon put into the air for these losses.
Q:Solar panels...??? HELP!?
Solar panels are primarily used to make electricity. What you choose to do with this power is up to you. New solar technology now looks to give the panels more than this one task. For example; - solar panels made into the shape of roof tiles can also be used for roofing. - thin film solar is being developed to add to cars and other mobile devices to provide portable DIY energy
Q:What capacity solar panel do I need to charge batteries with a total capacity of 25,000 mAhours in 8 hours?
WIRE THEM IN PARALLEL BUT MUST VIA ONE BLOCKING DIOED FOR EACH 4V BATTERY BANK ( LIGHT) BETWEEN SOLAR PANEL OUTPUT TO EACH BATTERY BANK. DIODE USES LIKE N5404 THAT CAN HANDLE 3A OR HIGHER IS BETTER. TOTAL AH = 9.8 AH FROM ALL 4 LIGHTS. NOT 25AH FROM YOUR MISTAKE RATE. TO CHARGE THEM FULLY IN 8 HOURS, CHARGING CURRENT AT LEAST .3A BUY SOLAR PANEL HAS OUTPUT 6V 2A ( OR 0W ) IS GOOD ENOUGH.
Q:How much do solar panels generally cost and are they efficient for my home?
At the present time, even with the government paying some, they are not cost effective. If you live in middle of nowhere and you want to be prepared in case all Hell breaks loose, and you can install your own, then I might consider them as a backup plan only if I did not have a running stream with 0 feet of drop. You can make a water generator really cheap if you have that creek. Call a solar panel company and get a quote. Do the math and see how long it takes for pay back. They are also allergic to hailstorms. My son did and it was something like 40 years to break even.
