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:What is the difference between Photovoltaic Panels and Solar Panels?
Both of them are different types of solar panel. EDIT: Misspelling on Jeff's answer below! I think he means 'silicon,' not 'silicone!' Solar cells are typically grown on a glass substrate or put onto glass. Silicon is currently the most common material, followed by CdTe or cadmium telluride. Other materials like CIGS (Copper Indium Gallium (di)Selenide) are breaking into the market. Some people have great hopes for organic or 'dye' solar cells.

Q:Solar Panel Question?
There is always a lot of confusion on this question so I built a webpage to show people how to do the math and pick the right system size. Most all public utilities will trade you kWh for kWh and then either settle up with you at the end of the month or every 2 months. So one week you might have all rainy days but the next 3 weeks you have 0 hours of bright sun even in the winter. This means you have no need to put batteries on your system unless you have a lot of power outages. Then you only need a few hours of battery backup power. At most 24 hours.
Q:Which is Better: DIY Solar Panel vs commercial grade solar panel?
They can be if you are well educated and skilled in their assembly and working functionality, provided you obtain the same high quality grade cells and do proper assembly. Chances are good however that your first several may be just a little below par until you really get the hang of it and become well practiced just as the professionals are. Does take a considerable amount of grunt work however so figure if this is best use of your time or if you'd do better to earn at your regular work and pay a professional to do that which they do best.

Q:Home solar electricity advice? Making the solar panels accessible?
Modern solar electric panels rarely fail. Because of this, if you would be installing them over a roof that only has a few years left on it, it would be better to redo the roof, first. In the unlikely event that a panel needs to be changed, this can be done in 30 minutes or so, because the panels are mounted on racks, with everything simply plugging together. I have never personally seen a solar installation go bad, but from what I hear, the inverter (a box that goes in next to your electric service panel) is usually what burns out after 5 years, assuming the install was done right in the first place. If you were to call roofers to repair your roof, they would somehow be able to get to your roof, by ladders, or a special truck. Solar installers use the same kind of equipment. They won't have a problem getting up there. A solar electric system is actually a very straightforward thing. No matter who installs it, if there is a problem, another installer should be able to diagnose and fix it.
Q:how to make your own solar panels ?
It used to be possible to get broken solar cells for free from solar cell and solar panel manufacturers and then it's just a matter of labouriously measuring the voltage and current characteristics of each fragment and soldering them in a combination of parallel and in series to get a crude solar panel with the desired output but the manufacturers have caught on and now sell the broken fragments by the pound so it's not really a cheap solar panel anymore but it's still very labor intensive and results in a fragile solar panel that is readily damaged and quickly degrades. Not really worth the trouble any more.

Q:How many wind turbines and solar panels does the world need to replace coal, oil and nuclear power?
Both the wind turbines ( windmills) and solar panels are less costly to implement than nuclear power and have less disaster potential. They have proven that Windmills miles out in the ocean are a great source of power. This dose not consume any land. For land bound areas they should use public roadways to line the windmills. For areas without sustainable winds they can use the combined effect of windmills and solar power. Honey, any motor needs oil. Whether it is a generator for a windmill or a nuclear reactor. Motors are what runs the world. Consider the amount of oil to run a nuclear facility. Tons more than a generator motor. Once a turbine is activated (motor started) the winds themselves turns the windmill. Each turbine is lined up with the next (wind farms) to push wind at the blades, they each push each other.
