Q:How would you build a Solar Panel that can convert Sunlight to Energy, just being on your house roof?
DIY okorder.com
Q:A couple questions about home made solar panels?
there are plenty of free sites that tell you how to install your own solar panels. Just google diy solar panels. as to how many panels you need, it depends on what all you're trying to have them run.
Q:Power Point on solar panels?
Energy conservation Use sensors that turn of lights and unneccassary equipment when person leaves the premises 2) Saves hard earned energy 3) Area of roof space depends on how much energy you want to collect from the sun.

Q:What is the real cost of Solar Panels?
They don't sell them by the square inch. It costs about $0 per watt of generating capacity. Unless you are connected to the grid you will need a battery bank to storage power for rainy days. As for the effects of weather ... you can probably make a cover out of plywood... but if your house blows away the solar panel goes with it. Before you buy one make sure your insurance covers it.
Q:How many LED's can power a solar panel?
The 40 kmcd rating is a measure of luminous intensity (how bright it looks), not a measure of output power of the visible light. We can estimate the performance of your proposed system as follows: The LEDs on OKorder each are rated about 20mA maximum at about 3.2V, or 64mW (milliwatts). If you use 470 ohm resistors connected to 2VDC, the current that will flow, per LED, will be about: (2V-3.2V)/470ohm = 0.0872A = 8.72mA The power taken from the 2VDC power source will be: P2v = 2V x 8.72mA = 224.6mW (per LED) The power input to each LED will be about: Pled = 3.2V x 8.72mA = 59.9mW (per LED) The LED has a luminous efficiency that can range from about 4.2% to 22%. This efficiency is the ratio of the amount of visible light output (in watts) divided by the input power (in watts). The OKorder listing doesn't identify the output power level (either in watts or in lumens), so let's assume a 0% efficiency. The LED output power will be about: Pout = 59.9mW x 0% = 5.99mW (per LED) A solar panel converts visible light to electrical energy with an efficiency that ranges say about 6% to 8%. Suppose the solar panel efficiency is 2%. Then the electrical power output by the panel will be about : Pe = 5.99mW x 2% = 0.72mW (per LED) If you shine 00 LEDs on the panel, the output electrical power will be 00 times that amount: Pe00 = 0.72mW/LED x 00 LED = 72mW <===ANSWER The power taken from your 2V source will be about: P2V00 = 224.6mW/LED x 00 LED = 22460mW = 22.46W The system efficiency will be about: Eff = solar output / battery input = Pe00 / P2V00 = 72mW / 22460mW x 00% = 0.32% SUMMARY: If you shine 00 of the LEDs on the panel, you will capture back about 0.32% of the energy expended, or regain about 72mW.
Q:What Are Solar Panels Made Of?
Solar panels are instruments made from Silicon Cells having the characteristic to convert solar energy into electricity. Sunlight is composed of miniscule particles called photons. When the sun’s photons are consumed by the silicon atoms of the Silicon Cells, the atomic creation of the solar panel is organized in such a way that electricity is generated. When these solar cells are accumulated together with wiring, they become one concrete panel.
Q:Im looking at getting solar panels.
Solar panels are very expensive and take many years to pay for themselves. You'd be better off contacting your congressmen to lift bans on Nuclear and other producers of electricity. That would lower the costs and save much more than the hassle of hooking up solar power and batteries etc.
Q:I will like set up a solar panel to cut down my eletricity cost in Cameroon.can you allocate me a supplier?
good idea going solar, i would suggest doing a google search, as their are many suppliers. then you need to calculate the amount of wattage you think these apartment houses are going to require. volts x amps = watts. if you are going to be off of the power grid, then you will need a way to store excess energy during good times,( lots of sun) in order to use it during bad times ( no sun ). or see if you are able to sell your extra power back to your local power company, check because some companies do not allow this. you could even have a generator for emergencies if you go off the power grid. on final note, solar is a pretty sizable investment up front and your profits are seen mainly in the long run, but you will get energy savings immediately, but more likely those savings will go to paying off the solar panels also, you will need a converter to convert the ac (alternate current) produced by the panels into dc ( direct current ) which is used by the apartments. it will tie in to the existing electrical system in the apartments. i know germany is really pushing solar energy and they offer their citizens some pretty sweet deals to go solar. the companies are profiting from this so i would suggest looking for a supplier in germany, first. they may have better deals, or try bp (british petroeum) they have been in the solar business for awhile. i wish you success!
Q:Solar panels single crystal and double crystal in the rain which is easy to use
From the cost of production, than the monocrystalline silicon solar cells to be cheaper, easy to manufacture materials, saving power consumption, the total cost of production is low, so get a lot of development. In addition, the polysilicon solar cell life than monocrystalline silicon solar cells shorter. From the performance and price ratio, monocrystalline silicon solar cells also slightly better.
