Q:How to prepare solar panels?

Q:Joule Thief vs Solar Panel?
Solar panels convert light energy to electrical energy with an efficiency of around 5%. A SMALL solar panel will only produce a small amount of power (watts) your joule thief circuit wont help because as you draw more current from the solar panel the voltage will drop; and your joule thief circuit just reduces the efficiency of the whole system Try adding another solar cell in series to get more voltage and more power.
Q:Solar Panel - Battery Charger 2V?
How many amps will you need? Remember v x a = power. The way those trickle chargers work is by sacrificing some amperage to get up to 2 volts. If you can invent closer to ~3V range that solar cells naturally produce thing will likely work better. A sign or a light that doesn't need a lot of power will work. Automobile battery packs might take a month to charge. Solar-Powered 2V Trickle Chargers are used mostly to keep things like boat batteries in storage from discharging, not to charge them.
Q:0000 watt Solar Panels?
About 2500 Sq. Yd.s
Q:Which is Better: DIY Solar Panel vs commercial grade solar panel?
I would like to go with commercial grade solar panels.
Q:how much money does solar panels save?
Where do you live? In almost all areas, solar power is currently really expensive. It looks like it'll be 0-5 years before they're cost effective... sorry to tell you! If your school is a tall building with few similarly tall buildings/trees around it then mini-wind turbines might be worth a look. You'd have to measure the wind for a year or so to get an idea of whether it's worth it though - in most cases mini wind turbines aren't very good either!
Q:Does anybody know if there are any courses for solar panel installation, and/or what trades you need for this?
If you are in the UK, then the Centre for Alternative Technology courses (CAT in Wales) have had some great feedback.. .. A lot of companies are actively recruiting and offer training courses as part of their induction. Have a look at the bigger ones recruiting near you.
Q:Solar Panel Watts?? help!?
Ok, seeing your icon is a female, I'll take a chance and offer a possible conversion factor. In diets, you count calories. When you exercise, you burn calories per minute or hour. In one exercise session you burn a total number of calories. And remember, 000 calories = kilo-calorie = food calorie. Same with solar panels and electrical power (same stuff, different units). Solar panels come in many watts sizes, like different foods and portions have different calories produced. When these panels are exposed to sunlight, they will generate this amount of watts for as long as you expose them (the units are kilo-Watt-hours), basically, like burning calories on a bike for an hour burns a total of x calories for that hour. If you have a 2-hour day, then a 00 watt panel will generate a possible total of 2 hours x 00 watts = 200 watt-hours = .2 kilowatt-hours. Just like calories burned during regular exercise varies over the year and your mood, the solar panels will generate varying level of power (watts) depending on the weather. And just like you burn calories at different rates by age and lifestyle, an average house power use is dependent on geographic location, size of house, number of occupants, etc. No real typical profile. I would recommend you get some personalized help in sorting out your power needs, A contractor/installer can give you a quote/estimate or general class of use. A second or third quote would keep you first estimate honest. Good luck!
Q:how do i pick out solar panels to match my battery bank?
I don't know where you got the idea you have 8 hours of sunlight. Assuming clear skys and no dust, forest fires, clouds or other impediments, the average sunlight available in North America averages out to approx. kw/sq. meter. That's the maximum available, at midday. Multiply this be the efficiency of the cells (I assume about 0%) and it means about 00 Watts/sq m. Since you have said you have a tracking system, this works out to about 00 * .344 * 2 = 43W/h per day (per sq. meter).
Q:how do i build a solar electric panel for my home?
Solar energy is very expensive. Or I should say, solar panels are expensive, because once you install them the power is free. A typical residential solar power system that supplies around a kilowatt of power at best conditions (noon, sunny day) will cost about $0,000. This includes the solar panel, the inverter (converts DC into AC), the cabling, but not installation (that would probably run you another $2000). One kilowatt is not that much electricity. It would run one microwave oven, or one hair dryer, or 0 light bulbs, and nothing else. Most houses use 3 times that at peak hours. So you would still likely get some power off the grid at peak time, and other times you can sell it back to make a little money. The good news is that solar panels are getting cheaper. They are around $5 per watt now, and are projected to drop to half that in the next decade. At some point, it will reach the sweet spot that makes solar an attractive alternative to grid power and more people will jump on board. There are some tax incentives too, but more would certainly help.
