Not sure what a good, working solar panel is, as it's either working (good) or not (not so good, maybe bad even...).
If you live in South Africa, have some good old Chinese friends who happen to sell wholesale solar panels, then expect to pay R1000 for a 12V 100W panel - that's about $70USD. For everybody else, expect to pay anywhere between two and five times that amount.
not much.
You can build a panel for minimum outlay. Get a good guide to help you to keep it simple.
That depends on the panel.
what is the cost of 3 v solar panal
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.
The cost of a solar panel can vary based on factors like size, quality, and manufacturer. On average, a typical residential solar panel can cost between $150 to $350 per panel. However, the total cost of a solar panel system will depend on how many panels are needed for your energy requirements.
About 1,000 watts per square meter of solar panel

About 200 Dollars
A common solar panel can produce around 200 watts of power and can vary based on the size and efficiency of the solar power you chose. There are also three things that can affect the amount of electricity that a solar panel produces: the amount of sunlight, the size of the panel and the efficiency of the solar cells.
