Q:Solar Panels for Jacuzzi?
yes you have to install an inverter to convert DC to AC....and a battery pack if you want to use jacuzzi on a cloudy day or at night
Q:Numbers behind Solar Panels?
For comparison, 36 of these make a normal 2V x 50W panel. Note they are not tabbed. This means you have to find a way to connect them yourself. The tabs are probably spot welded on by the suppliers. A supplier below has kits of these with tabs, as needed to connect them together. These are not suitable for grid connect, because the higher voltage needed makes do it yourself panels a dangerous and litigious thing to have on your roof. Maybe you could buy a smaller pack from the link below to compare tabbed and untabbed and work out what to do. Your power calculation is a bit incorrect because the sun is only present some of the time. The 36 cell module would produce 50W when square on to the full sun. The sun may be out for around 2h a day in some places and times of the year. However it is the equivalent of 5h full sun, because of the changing angle throughout the day. Look this up on the internet for your region. Temperate zones may be a lot less. One pack in your link is 36x3 = 08 cells. Thus 50W per pack x 5h a day gives 750Wh per day and 274KWh/y. In reality it will always be less because of regions, weather, clouds, dust, inefficiencies, aging of cells.

Q:where could i buy a cheap and low cost solar panel regulator?
investigate Tractor grant... they have been given small, medium and massive. Wal-mart additionally has infants for image voltaic lights... you ought to string them very close jointly to get volts up... i offered an merchandise which you defined as what you will make -- inexpensive fan with a image voltaic panel on it from Wal-mart--- it cools the interior my vehicle on sunny days.
Q:How do you make a solar panel?

Q:How much energy would this solar panel produce?
The world record efficiency for a solar panel is about 42%. At the equator, you can get up to about 000W m^-2. The efficiency of commercial cells tends to range from 0-20%. They're almost all single junction cells, so will never exceed 3% efficiency. To work out your maximum power output, multiply 000 x efficiency (as a decimal) x area covered. So an 8m x 0m solar panel would be 80 square metres. At 5% efficiency its peak output would be 2000W or 2kW. Total energy output will be different, since it won't be maximum power output all the time. In fact, it will more likely generate something like 20% of its maximum theoretical output, since the Sun won't always be overhead (and sometimes it's night!). The 2kW panel above might have a mean output of 2.4kW, or 57.6kWh/day.

Q:how much would it cost to generate MW electricity by solar panels??? and how much land it requires ?
There okorder.com/ Why pay thousands of dollars for solar energy ($27,000 average cost) when you can build your own solar panel system for just a fraction of the retail cost. You can build a single solar panel or you can build an entire array of panels to power your whole house. Some people are saving 50% on their power bill, some people are reducing their bill to nothing. But what’s most impressive is that just by following these instructions some are even making the power company pay them!
Q:A good brand of solar panels for my house?
Mitsubishi panels have served us well for 3 years so far, no problems. Kyocera had a well-known problem many years ago, but they lived up to the warranty and replaced defective panels. Their current products are considred good. I like the value delivered by Suntech panels. Might be a best buy - shop around. I have not heard about any of the major brands having trouble, lately. If you're intending to connect to the grid, be cautious about used or blemished panels. While they might work fine, they usually are ineligible for rebates.
