Product Description:

1. The Introduction of Solar Module

Solar modules use light energy from the sun to generate electricity through the photovoltaic effect. The majority of modules use wafer-based crystalline silicon cells or thin-film cells based on cadmium telluride or silicon. The structural (load carrying) member of a module can either be the top layer or the back layer. Cells must also be protected from mechanical damage and moisture. Most solar modules are rigid, but semi-flexible ones are available, based on thin-film cells.

Q:Solar panel for laptop?
Actually they do make these... u have one but the voltage is no guaranteed as depends on the radiation from sunlight. I have a 8v 60Watt folding solar panel... works great and does charge laptop but not consistent. It works better when you also have an external battery with you as well. Battery will charge laptop Solar panel will charge battery Also most important... put laptop screen on super dim / power savior mode or else laptop will eat up energy. I have a desktop replacement hp laptop and able to keep it charged at 9volts just under 2amps... (38 watts)... on power save mode of course ALLPOWERS 8v 60Watt folding solar panel charger Also.... Poweradd Pilot 30000mAh multi-voltage (9v -20v) portable chargers. Remember solar panels are nothing without batteries... not just for storing at night but also storing all the energy you can get. If not you would only be powering the load
Q:how to chose the right solar panel for my home?
Talk okorder.com has good info. What state are you in?
Q:Solar panels on the roof?
Lots of folks are installing them in my neighborhood in the Mid-Atlantic. I'm going to hold off until I can ask my neighbors how much their electric bill has gone down, after they've had the panels for a year or so. I don't see any reason to rush into it. Also, I'm a little concerned about what happens if a leak develops in your roof during or after installation. Who pays to fix that? That, plus the west side of my house faces the street, and I don't think I want my solar panel array to be greeting guests and visitors...I'm just not that in love with the looks (although the shingle- or tile-like versions of panels that Tesla is advertising would not be bad). So the panel installers would have to be satisfied with an east-facing installation on the rear slope of my roof.
Q:2v vs 24v solar panel?
The choice of solar panel voltage comes down more to what the panels will be connected to. You're right that power can remain the same at the different voltages. Higher input (panel) voltages are sometimes used in inverter systems to reduce the effect of voltage draw-down. 2v panels (about 20v open circuit) work well for charging 2v batteries, connected in parallel, through a charge controller. For use of a grid-tie inverter, higher input voltages are sometimes used to reduce the effects of draw-down. You want to select and wire (parallel vs. series) your panels based on the input voltage requirement of the load, whatever it may be.
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:are solar panels worth buying?
There are different kinds of solar panels. The biggest division is between photovoltaic panels that produce electricity and thermal solar panels that produce heat for hot water and space heating. Commercial photovoltaic panels are from 8 to 24% efficient while solar thermal panels are from 60 to 80% efficient. Solar thermal panels especially for hot water have a much higher ROI (return on investment) than photovoltaic panels. A solar hot water system may have a payback period (when savings equal the investment) as short as 3 to 5 years while photovoltaic panels will typically have a payback period between 7 and 5 years. Solar panels especially in times of low interest rates may be a very worthwhile investment with a better return than you can find almost anywhere else. But they are also highly dependent upon your situation. Owning a home with a good southern exposure is a prerequisite.
Q:have you ever installed solar panels for your home?
Yes, solar panels can cost allot of money up front. They will eventually pay for themselves over time. Today it is pretty easy to install solar panels. They've made panels so easy that you can pretty much just have a technician hook them up to the electrical box outside your house you start saving money. Any electricity you generate over what you use...the utility company will PAY you! If you dig my response please like me on Facebook (link below). Thanks!
Q:Solar panel technology?
I okorder.com to get more information on the subject.
Q:How big of a solar panel system would I need to get ?
I think if you have the land have a solar array on your land. Putting on the house could cause it to collapse! 400 kilowatts per week is a huge usage. Turn some stuff off and don't leave the entertainment stuff on standby. Fill empty spaces in your freezers with blocks of polystyrene and be sensible with usage.
