Q:solar panel regulator?
wire them in series parallel to get 8 volts at 200 mA, and that should charge a 2 volt battery. You may want to put in a series diode to prevent the battery from discharging into the panel when the sun is out. At 200 mA, depending on the battery size, you may not need much control, as that low a current will not overcharge a large battery, like a small auto battery. In fact it will take a very long time to charge it. edit: But do i need to add a regulator? If by that you mean a voltage regulator, no, as a solar panel has a high output resistance, and that will limit the current into the battery. If you mean a charge controller, if the battery is small, you may need a charge contoller to avoid overcharging the battery. But that is not a voltage regulator. .
Q:Is there anyone trying to create a cheaper and more efficient solar panel?
Solar panels are one of the hottest areas in materials research today - from basic science to applied production techniques. There have been major strides in thin-film manufacturing technique as well as silicon technology. There's not a lot of hype about it because solar panel manufacturers don''t really need to advertise yet - they are selling at factory capacity with demand for more. Standard silicon solar panels now sell for around $3 a watt, and grid parity is expected within 5 years. Reference is to the MIT Technology Newsletter, which runs several articles a month on new solar tech.
Q:Single crystal solar panels and polycrystalline solar panels
Monocrystalline silicon solar cells are mainly made of monocrystalline silicon, compared with other types of solar cells, monocrystalline silicon cell conversion efficiency of the highest. In the early days, monocrystalline silicon solar cells occupied most of the market share, in 1998 after the retreat of polysilicon, the market share accounted for second. Due to the shortage of polysilicon raw materials in recent years, after 2004,
Q:how to make a solar panel?
All you need to do is to learn how to build solar panel to produce your own electrical energy through solar panels. These solar panels take and keep the energy from the sun and turn it into usable electrical energy that we can use every day in our ordinary lives. Generally, the majority of people that knew about solar panels think that they won't benefit from its use because they just work in sunny areas. That isn’t the case. In fact, the new generation of solar panels can produce a lot of electrical energy even on rainy weathers. Learning how to build solar panel is very easy: first they need to be installed (most of the time, on the roof of homes) and then they take the energy from the rays of sunshine and convert it from solar energy to electrical energy. Solar panels must be kept from shading, as shaded cells draw energy for themselves from other cells. Things you need to know: . Solar panels using monocrystalline cells have high conversion efficiency, and take up less space, but lack shade protection. 2. Solar panels using polycrystalline cells have even higher conversion efficiency, take up even less space, but still lack shade protection. 3. Solar panels using amorphous silicon cells have lower conversion efficiency, and take up more space, but do have shade protection. This can be especially important on a sailboat. Once you have determined the size and number of solar panels needed, you will be better able to determine where they will be placed. The best places depend on the roof's length and size of the panels. Take your time and think it through. The simple answer to how to build solar panel is none other than the sun. Select locations that will get maximum sunlight without shaded spots. In placing solar panels, consider the use of extra bars/braces to secure the panels. You obviously want them to remain stable.

Q:What to do with a solar panel?
Solar cells convert the energy of the sun into electricity. By using items commonly found in the home or your local hardware store, you can make a solar panel to demonstrate this photoelectric effect. You can also save energy by converting some of your traditional electrical supply over to solar power. Use sheet metal shears to cut the copper flashing in a square or rectangle to fit the size of the electric burner. Be sure to use a piece of copper flashing that is thoroughly cleaned. You may use sandpaper to thoroughly remove any sign of corrosion before proceeding. Place the copper flashing on the electric burner and turn the burner on. You will need to cook the flashing for as long as 30 minutes or more to develop a thick layer of black cupric oxide.

Q:Im looking at getting solar panels.
I recenty had a system installed for my home, you can get a system that will dramatically reduce your over all electric bill for $20K. My system which is currently running my meter backwards from about 8:30 am till about 6pm cost me around $8K, I did get a $0K rebate and I'll get a $2K federal tax credit. I just had the system installed this week, so I won't know how much it will take away from my yearly consumption for a while. I personally think an overall system is a beter financial option. If you get one that just runs your a/c then you lose the benifit of the energy it is producing when the a/c isn't running. It makes sense to have a system to run an item that is located away from a source of electricity, but then you would need to invest in a storage system. The best advice, is to have a contractor come out and give you a quote. You can get a system that will produce part of your electricity all year and you can always add to it at a later time to eleminate your electric bill.
Q:Would you put solar panels on your home? and why?
Why: ) It's a great technology. 2) It has low impact to the environment. Why Not: ) Initial cost is substantial. 2) solar panel technology is greatly improving. I would hold out for a few more years when you can actually use it as a sustainable source and as a replacement source and not so much a suplimentary source.
Q:I have a question about solar panels?
But at night where there is no sunlight does all the electricity shut down for the night? Electrical production shuts down, but most solar electric systems have some way of storing power. There are two main types of storage: . Grid tie. Basically this uses the power grid as a virtual battery. You produce extra power during sunlight hours to sell to the grid (other people use it) and you buy power from the grid when the sun doesn't shine. This is usually the most economical system, but whether you save money depends on a lot of things like: cost of installation, location, government subsidies how much you get for the electricity you sell buy. In other words, the details matter. Mostly location, which determines how much sunlight you get, electric rates, and subsidies. 2. Batteries. Usually a large bank of deep cycle lead acid batteries. Usually only used in off-grid systems and the cost of electricity is usually not competitive with grid electricity.
