Q:i am asking about the solar panels?
First of all, make sure that you are taking readings in the dark (with the solar panel indoors and covered). 0.433 is a reasonable forward voltage for a Schottky diode. Ideally, it diode should read open one way (possibly OL for your meter), and 0.4 the other way. If it's reading OL both ways, the diode is bad. You can either unsolder it or cut it out and verify that it is bad.
Q:how much do commercial solar panels cost?
The size you pick, therefore, should be decided on per your requirements. A 4kw system will need between 0 and 20 solar panels, with an initial cost of around £7,000 for the module and installation. Systems larger than 25kW can't be accommodated on existing buildings. Instead this option is for those of you with vacant land, a location such as a farm or another open space.
Q:Solar panels........................?
If your purchasing solar panels for a building or colony where a few families live together, the cost of the panels can be distributed or shared. And loan and electricity bill wont be the same. Loan is a one time transaction while electricity bill you have to pay monthly and everytime. You dont have to buy solar panels every month lol. So its a better option to spend on solar panels although it maybe a big amount, rather than paying high bills every month....
Q:What solar panels are the most efficient?
There are a lot of solar panels available today's. The problem of the efficiency is the proccess of converting, these cells use the photons of the sun to react with the ( Si compound inside the cell) due to the little thing that cell's are only a fraction of these energy is converted, remember that solar cells are paper thin and the really problem of these cells are the voltage not the amps. A single 3x6 inches solar cells can produce 3.6 amps but only 0.5 volts.
Q:Question about Solar Power and Wind Power?
Solar panels and wind/water turbines all produce the energy and feed it into the batteries. Outfeed from the batteries thru an inverter to an electrical panel. From panel to outlets, into which you plug standard appliances and items. You can also get some appliances that run off of 2volt. Check with r.v. companies and suppliers for these. You can also run low voltage wires straight from batteries to switches to lights, fans, etc if you put in 2v ones. Just like your car has lights, fans (ac blower), and radio. As for how many batteries you need will depend upon how much ebergy you will use. You will need to figure how much all of your items use per hour. Then figure how long your charging device could be down for at a time. Solar panels will not charge at all for the 8-2 hours of nightfall depending on your area. Wind turbines will charge day and night so long as wind is of sufficient speed. Water turbines will charge 24/7 so long as water source(creek, stream, river) doesn't run dry. Neccessity/hr=N, time without charging =T. N times T = the amount of backup power you need to get you thru till charging sysytem kicks back in.
Q:How do you make your own solar panels?
if you're hoping to put 'em on your house and use 'em to supplement power from the grid, then you'll want to buy them. the panels have to be made with exotic chemicals, in a clean environment, with dangerous chemicals. anyone who tells you that you can make 'em yourself will be asking for money for the plans. in truth, you could get an old panel, and, if it was the right voltage, you could use it to charge your rechargeable batteries. typically, that's not the hoped for application. and, to get enough power for you house, you're not going to be able to do it yourself. whenever you buy anything, make sure you know what it can do. ie, read the fine print. if it's a few hundred (or thousand) dollars, it's not going to be useful to augment your home power. in addition to the strength, there's also the equipment that's needed to sync it up with the power from the utility, and that's neither cheap, nor a do-it-yourself project. i've seen lots of panels but when you read the specs, they're pretty useless. not good for battery charging, not for hooking up to your house. in other words, interesting projects with no practical use.
Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
I don't think so, but if it did, it would take a very long time. You need enough wattage or amps to push the power in the battery and 3w may not be enough. You would be better off with a small 2v battery, maybe the type they use for emergency lights. I would use a sealed battery for this type of setup because car batteries are designed for heavy charging with alternators from 60 amps and up.
Q:Single Solar Panel savings?
No matter what or how you do it it is best to get off coal and nukes. So it cost a little bit of money you are buying 30 years of electric. How much will you spend adding in cost of living increases over the next 30 years? Solar really is pretty cheap if you take the time to do the long term math. If you use your cost at to days rates it does seem like a lot. But if you do the math like in real life with 3.5% compounded cost of living increases per year and 6.5% fuel increases per year. Well, you pay a lot more renting power. One other thing to think about and Al Gore keeps pointing it out is, Will your off spring be alive in 50 years from now if you don't buy the solar panel? Kind of like not going to the doctor because you can't afford the bill. Well I would rather owe a bill to a doctor that I will have trouble paying then not be alive at all to try. If you don't have the money to jump in and go full blown Green you should buy a starter system. You can get a system that can be expanded to 3000 watts (enough to power an energy efficient home). Would cost you about $8000 USD to get started and then you could add three solar modules at a time till you get it up to the 3000 watt max. And even have backup power. Or you could just buy a 000 watt system for about the same price and just add 3 of them over the years. There are many ways to get started. The deal is everyone needs to get started even if it is a small system. If all 50 million homes in the USA would install a small 000 watt system with 4 hours of sun light a day. We would provide (000 watts times 4 hours times 365 days times 50 million homes) 29,000,000,000,000 watts not from coal or nuke plants per year. I wonder if that would help?
Q:Can I join 5 or more solar panels into line to the battery bank. I don,t have a regulator connected, just st?
I am pretty darn sure you need the regulator because all the advertising says that you must have one if you have more than one small solar panel. I think you can overcharge your batteries otherwise. Solar power is still not cost effective, so most people have solar power because they care about the environment more than they care about expenses. If you are poor, it is better to skip solar power, unless you are in an area where there isn't access to electricity. For example, we have a cabin without electricity. I am a strong environmentalist, too. Solar power is too expensive still, for low income people. It is better to focus on energy conservation, imo. such as change your roof to white, to save on A/C, as the head of the US energy dept. says (he is a nobel prize winning physicist). PS Dave might be right on that stuff, i don't know. but all the ads say you need a regulator if you are going to have more than one solar panel so I assumed this was due to risk of overcharging.
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
