Q:information on solar panels?
The main components for a solar electric system are the panels, racks for mounting the panels, and inverter to convert the panel's DC power to AC, which can be pumped into the grid if necessary. There would also be various electrical supplies involved - wire, conduit, possibly a switch and/or circuit breaker. On the paperwork side, there's a building permit, permission from the power company to connect, and some inspections. Although it could be done by a homeowner, it's not a trivial project, and the best way to get it set up is to contract a professional solar installer. They all give free quotes, and can explain your various options when they visit.
Q:Why are solar panels not that efficient?
I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity
Q:45 Watt Solar Panel Kit Harbor Freight?
Yes, 80 watts will be nearly twice as useful as 45 watts - but 80 is still a small number. Solar panel systems need an inverter and there's a slight energy loss at the inverter. And, if you want to use the day's energy at night, you'll need a battery or two. And every time you move energy into or out of a battery, you lose a little of the energy. All this is to say that you need to sum up the wattage of your appliances and add a fudge factor to accommodate for the losses. I looked at the kit and was moderately impressed. $200/45=$4.44/watt; that's a reasonable price but the links I left below talk of prices as low as $2.58/watt. Also the Harbor Freight kit doesn't contain an 'inverter' which you would have to buy. Also the wattage advertised for any solar panel assumes the thing is clean and pointed right at the sun on a clear day.
Q:can a small solar panel be charged with lamps?
That would depend on the frequency that the solar panel accepts and the frequency of light that your lamp gives out. It may or may not work. The sun gives out a much broader spectrum of light, which is why solar panels are much more effective in sunlight. I have seen solar panels charged by lamps, but it usually doesn't work that well and I have never seen it work with fluorescent lighting.
Q:How do you hook up solar panels to your electricity?
Backwoods Home Magazine had a great step by step section in one of their magazines on solar energy, panels, hook-up, etc. You can go to their website, pull that issue up and order the magazine and I believe they offer it on CD. This way you would have a reference guide at the ready when you tackle this project. Godd Luck!
Q:how much is one solar panel?
no one has answered because you asked a question that cannot be answered. It is exactly the same question as how much is a car?. Do you want a passive solar heating panel, a solar electric panel, .5 Volts, ,000,000 BTUs, do you want just the panel or the panel installed and functioning, or what? the answer is between $5 and $5,000,000.
Q:how to build solar panels?
i think the evil Genius book has how to build home made solar cells.
Q:Where do I find solar panels?
How much it costs, and whether it is worth it, really depends on where you live, and how much power you use. A very conservative house like ours, in an ideal area, could get by with a system that costs $5000 to $7500 net after incentives like tax credits. A house that uses a lot of energy, like a massive one with air conditioning, could need an array costing ten times that much. The only way to even get close on an estimate is to call a local solar installer for a quote. If there are no local solar installers, that's a clue that your area may not be very good for solar. Consider solar hot water also. That's generally cheaper and pays back faster than solar electric.
I don't have any practical experience building solar panel arrays to power a given device, but allow me to make this observation. Solar cells, when exposed to sunlight, will each generate a given amount of power (watts), and by wiring these in series, you will increase the wattage. Now, a panel three feet square will give you a certain amount of power, provided all the cells are wired correctly in series, and it may not provide enough juice to light the bulb. You can work around this by adding a step-up transformer (which takes the incoming power and boosts it to the desired level for output, with no moving parts). Voila! You've illuminated your bulb. I will admit, though, you'll have to do some math to determine what you need. A search on the Web will help you find the formulae and other information you'll require. Good luck.
