Q:Are solar panels efficiency already calculated in their power rate?
If it says STC or Standard Test Conditions on the nameplate or documentation, then that means 80 watts under bright sun at an unrealistically cool temperature. It is rare to see that power in real life, except when the perfect storm of conditions come together. There is also a PTC rating for some panels, which is more realistic. If the panel does not say STC or PTC, the manufacturer is free to make up whatever test they feel like, which generally leads to ridiculously overstated power. As for efficiency, for residential panels, that's generally only of academic interest. A 80-watt panel is 80 watts, regardless of the efficiency. A more efficient panel will take up slightly less space, but most people are more interested in the total price, since roof space is generally not an issue.
Q:Where do I find solar panels?
Where are you located?
Q:How to build a solar panel for lighting/heat source?
Some people that have advanced technical skills can even try to build their own solar panels to save money. In case you decide to go with this option you should know that today is fairly easy to find lot of literature about building your own solar panels which of course makes things easier. Still I would recommend this option to people without advanced technical skills. renewableenergyarticles.blogspot....
Q:What specification of solar panel do I need?
I okorder.com/ says they have DC to DC solutions from 2 V for most laptops.
Q:What to do with a solar panel?
Hey AJ, Tom is quite right, a panel that size is a great trickle charger at .2 amps. If you have a good sized 2 volt battery, like from a truck, or for a boat trolling motor (it should be at least 60 amp hours) you can hook it to the battery and it will charge it slowly anytime the sun shines. Don't worry about the voltage, most 2 volt nominal volt panels are wired for 8 - 9 volts, and if you hook them to a battery, the panel voltage comes right down to the batteries charging curve voltage anyway, they are designed for that. What you do need is a diode. A diode is an electrical check valve, allowing current to flow in one direction, but not the other. This will prevent the battery from discharging through the panel at night. Many panels today come with diodes inside the junction box on the back of the panel. If yours does not have any, go to Radio Shack, look for a 6 amp silicone diode, usually around75 cents. Put it in series between the panel and the battery, then, while you have a voltmeter hooked to the battery, connect the panel/diode to the battery and see if the voltage goes up slightly. If it does, you're all set. If not, turn the diode around and try it again. It has to be connected into the circuit the correct direction. Many people will state that you need a charge controller, but this is not necessary if your panels max current, ISC is less than 2% of your batterys amp hour capacity. In your case, if you have a 60 AH or larger battery, skip the controller. There is a great discussion about this in Richard Perez's book, I will list it below. If you want to learn more about these devices, there is a great magazine that gets into the nuts and bolts of renewable energy, it's called Home Power Magazine, the link is below. We started by hooking a slightly larger panel to some golf cart batteries 2 years ago, reading that magazine and going to some energy fairs. Today our home is completely powered by the wind and sun. Check it out sometime. Take care, Rudydoo
Q:How can I be part of the solar panel industry?
Manufacturing your own electrical solar panels is out of the question. They are built much like computer chips and setting up a plant to do this would cost millions of dollars. You could become a solar system installer. These businesses install solar systems on homes and are paid for this service. You will need a significant amount of technical training to do this though, I would guess at least two years (the last thing you would want to do is damage someones home or design a system that is dangerous). I would suggest that you go into business making energy improvements to homes that do not involve solar energy. Most people can get the best value for their money by improving the air tightness of their homes (several tubes of well placed caulk). Other things you could offer would be the upgrading of door, Windows and electrical box seals. Insulation jackets around hot water heaters is also something a small firm could offer home owners. Other energy improvement are also possible and you could offer a whole shopping list of improvements to a customer. Good luck
Q:Solar Panels?
Well, the best way to buy solar panels is to shop by watts. Solar panels come in a wide variety of watts, from to over 200. However, the more watts a panel has, the more it costs. I would suggest getting small things first, and gradually converting to solar power so as to help the environment and save money. If you have an outdoor pool, buy a solar collector to heat it. It will extend your swimming season and once you hook it up, you won't have to worry about it. (My cousins have this on their pool.) Also, there are solar cell phone chargers available for purchase, you could get one of those. As for your house, you would need several solar panels and a converter to be able to power your whole house on solar energy.
Q:Solar panels require big initial investment, how can I check if the money I save will be more than that?
you have a really good formula for figuring out what you will save. as long as you dont live the the arctic during the winter months you should be fine! this investment will definitely pay off in the long run and help the environment. just like the other guy said, the utility company would have to pay you back any excess energy you produce that you dont use! you can calculate how much your average electric bill is and then compare by how much you would be saving. you can multiply the number by 5 and 0 years and so on to see how much you would save ultimately! this is a great way to save your own money and never have to be dependent on the electric company again! yes you will definitely need a battery to hold a charge for overnight use good luck!
Q:Is this a good kit for building a solar panel?

Q:How to select solar panel for this application?
First, you need to make sure that your battery can take a regular 34Ah discharge without damage. The usual wisdom when using deep cycle lead-acid batteries is to allow for no greater than 50% discharge. This is to prevent the battery from ageing prematurely. Note that automotive batteries are not usually considered suitable for deep-cycle applications. Best allow for at least 200Ah capacity. Your solar panel capacity needs to take into account that whatever the nameplate output of the panel, that will be what it will produce under ideal conditions, actual output will always be less, often quite a bit less. You also need to allow capacity to cope with dull, overcast days when the light level is very low. You can get solar maps that will give you the sunshine hours and irradiation levels at your location. The solar panel capacity ends up being a juggling act between available funds/space and how critical it is that the light always works as desired. Let's say you had a 400W panel, which sounds quite generous. In the middle of winter, it may produce only 75W for 5 hours on a dull day, not quite enough to run the light for 0 hours. Would you expect several such days in a row? How many days could a 00Ah of battery capacity cover under these conditions?
