There isn't a simple answer to this question. It really depends on the amount of power you require from your solar panel and whether these solar panels are for homes or for a small portable device. You are going to want to first determine the amount of power you require for your load and then go shopping for one based on that need to determine how much it will cost.
Typically you can purchase solar panels for about $3.00 per rated watt if you plan on hanging the panel yourself. Prices have fallen lately on the internet, but after shipping charges, this is still about right. Each rated watt will be able to produce about 2 watts of power each day on average of actual real power. (For the purpose of planning your panel layout). Typical payback (before refunds and grants) is about 25 to 30 years.

depends on the size of the solar panel and the weather. the bigger the solar panel and sunny weather will generate more electricity
The amount of solar energy absorbed by a solar panel depends on factors such as the panel's efficiency, size, orientation, and location. On average, a solar panel can absorb around 15-20% of the sunlight that hits it, but this can vary.
That depends on the panel.

I assume they come in different sizes, but a typical commercial solar panel generates about 50 watts.
Depends on the type of solar panel. You would need to look at the manufacturer's data to know the exact amounts.
