Q:How many LED's can power a solar panel?
Your question has a lot of science involved that I don't understand perhaps the link posted in my source for this answer could help you out? It a site containing only info on LED Lights. Good Luck
Q:What is the best low power alternative for TV set, to use as screen for dvd player, with a 30watt solar panel?
Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
Q:Which is the least expensive, yet still very efficient, type of solar panel?
Since you are asking for a rather technical answer you should be aware that solar panels come in several varieties. Two broad categories are photovoltaic panels which have achieved marketable efficiencies of around 24% and solar thermal panels which are routinely achieving efficiencies of between 60 to 80% while they are also much cheaper than photovoltaic panels. So the short answer is solar thermal panels. But what can you do with solar thermal energy. The answer is just about everything you can do with light energy. Sometimes additional equipment makes the efficiency drop to near that of photovoltaic panels. The trick is to keep the devices as simple and as efficient as possible. Solar thermal can of course be used to heat our homes. But it can also be used directly for air conditioning. The type of air conditioner uses a slightly different principal but it is one of the oldest that was once used in ice houses before refrigerators. It is known as an absorption system. At some point you may want to make electricity from the sun's heat. The most efficient commercial systems are not photovoltaic but solar thermal. There are several commercial systems where increased scale improves efficiency. The most efficient is a solar parabolic dish system combined with a stirling engine. At around 30% efficiency it beats photovoltaic and other thermal systems. At this level of commercial development, the various systems are more often described as solar collectors rather than panels.
Q:Solar panel questions...?
anythign can be scratched/ruined/altered if not tended to properly.... remove the first biggest layer of snow and leave a lil under to try to see first if it melts away on its own (dpeendin what season of course) if not than get some luke warm water and soak the snow.... slosh it off with a rubber shovel or mop.broom whatever wont damage ur panels. anythign you take care of will last longer and take care of you.... and solar is expensive to put in and can be expensive to maintain . depends where you have most sun and depends how many resources you use, if you leave the tv on absent mindely all night and take 50 min showers or blast the heat with jsut on epathetic lil donwpour of rain instead of just BUNDLING UP like a alot of lazy *** ameicans and.or rich careless bastards of course youa re goign to be paying up and out of your asshhhhh-hooooo and nooooo there are some different materials solar panels are made of, there is a main base/core they use but im sure there are AT MOST two...the rest is either glass or plastic! depends for what you want and how many , includign size.... good luck!!!! excuse my typos
Q:Solar panels in the Bay Area?
I know nothing about the Bay area, I live in KC. However, I believe that solar is the best answer to alternative energy. We should have solar panels everywhere, the suns going to be shining somewhere. I propose we make gigantic panels in the deserts where the sun shines and nobody lives, and hook everybody up to the grid. They can store energy when they get a lot of sun to make up for the dark days. They are expensive to make so we should start building them one by one all over. The sun is not going to stop shining for millions of years. Plus there is no pollution from solar. So, yes put them in the bay and back here in KC too.
Q:Need Help, 2v Solar Panel for Emergency?
Research using solar panels on stock tank water pumps. Same concept - you use a solar panel to power a remote something or other, only you would have to use a battery charged by day to run the camera at night. It does not look like you would need too powerful of a solar panel, the camera server says it needs less than 5w, no idea on the cameras, so check that out, but the whole system looks rather low power. You could easily get the necessary panels, maybe the battery too, for... I would say $200 (not in one package, you would have to get separate things). Connection of everything would be simple, no electrician needed (but keep that to yourself, depending upon state rules and regs).
Q:where can i get a small solar panel to power an outdoor water pump?
You will need more than a small solar panel to run a pump continuously, unless you don't mind that the pump only comes on during the day while the sun is out. st you need to know what the power demands are of the pump in question. Not only do you need to know the rate of the power draw from the pump, but you will also have to calculate how much power the pump will draw from your solar system every day. You will have to factor in that the sun doesn't shine brightly every day, of course there's also night, so you will need a storage battery, charging system to go along with your solar panel. Now most pumps like the one you described are 20vac. Most solar panels, the batteries, the chargers are 2vdc. In order to get 20vac you will need an inverter. Once again, you will have to make sure that the inverter you get can handle the demands of the pump. A solar system that actually works for you takes some carefull planning, it's not something that you can just hang from a tree. None of what I just descibed will be inexpensive by my definition, so if it were me, I'd dig a trench across the driveway, install some direct bury cable on a GFCI circuit out of my main power panel save a bundle.
Q:what are the parts of a solar panel?
A solar panel is just a collection of solar cells all wired up in parallel and series to provide a useful voltage. Typical solar cells only provide half a volt, maybe less, so usually you put 2 of them together to get a 6v solar panel or 24 of them to get a 2v panel. Solar cells are made in various ways, the most popular are silicon solar cells which are made with a chunk of silicon with a P-N junction in the middle and contacts on either side. When a photon of light comes in, the energy of the photon is converted to electrical energy. Individually, photons contain a tiny amount of energy, but when you have a solar cell in the sunlight, billions and billions of photons hitting it constantly create a useful amount of electrical energy. Solar panels are incredibly simple!

Q:How to charge a Battery with Home Electricity and Solar Panel together?
No, don't connect the panel directly to the battery. You need to isolate the solar panel charging output from the AC-powered charger. A couple of high-current diodes arranged with their anodes connected to the charging sources in the positive supply line will allow either the charger or the solar panel to lift the voltage high enough to charge the battery, albeit with about 0.6 volts dropped across the diode. Both cathode ends would be connected to the battery. This arrangement allows a positive current to flow from either or both charging sources at the same time, although in practice, one will generally be higher than the other. Also, if the AC charger's voltage is significantly higher than the solar panel, the charger may always charge the battery. You would need to regulate its output to be slightly lower than the solar panel when it's near it's minimum useful operating voltage. (note that the 0.6 forward bias voltage on the diode might prevent the solar panel from completely charging the battery if it has any voltage regulation on its output)
