Q:What are the benefits of solar panel heating?
Solar okorder.com/
Q:solar panel, dc light help?
No longer just any bulb will work on DC power. Any light bulb that's for 0voltage won't work on DC energy due to the fact that the element has too much resistance for a DC vigor provide to create ample heat to generate mild from the aspect. Nonetheless the do make mild bulbs that are designed to function on a DC energy supply and i might extremely recomend making use of the proper bulb with the proper vigour provide. Purchase some 2volt bulbs to be dependable......
Q:do solar panels have to be in direct sunlight?
As above, but also make sure the panels you use will still produce if partially shaded. Some older panels will quit producing if you so much as put your hand over a small portion of it. Newer ones don't do this but are more expensive. As you may need more panel area to produce enough energy to fill a battery (if that is how you go) make sure you have the room/roof area for additional panels.
Q:How much money does it cost to make ONE solar panel?
If okorder.com/.. Low-cost crystalline panel manufacturers such as Suntech are believed to have costs in the $.50/watt range today - making it $300 for a 200-watt panel. That doesn't mean that one can buy a panel for that price, of course. If you mean a DIY panel from purchased solar cells, the cost would be closer to $360 for an equivalent-powered panel, not counting the price of the frame, and the labor. A homebuilt panel would not stand up to decades of weather unless one spent even more on the frame. And since such a panel would not have safety certification, it could not legally be connected to the grid in most places. If you meant a water heating panel, please update or post another question - I'm sure people will chime in.
Q:SOLAR Panels?
$8,000 invested at 5% interest would pay you $900 per year for the rest of your life. If you spend $40 per month and would save 25% of that, you would save $420 per year. To be fair, the savings would creep up with the electric rates but this would be off-set by maintenance cost and equipment attrition.
Q:How many volts does a small solar panel on a calculator produce?
Wrong forum
Q:Advantages and Disadvantages of using solar panels?
Initial cost , space occupied AND DAILY CYCLE (unless through a battery) are the only disadvantages. REST ARE ALL ADVANTAGES
Q:Does It really cost that much to Install solar panels?

Q:Solar panels with snow?
In heavy snow areas, snow can build up on panels. If you mount on your roof as most people do, the angle of the panels will help the snow to slide off. Some people encourage the snow to slough off with a very long-handled squeegee or stick. You will see a drastic power reduction when the panels are covered with snow, even if it's just a few of them. However, the panels are made to take snow load, they won't be damaged. Generally, they are also designed to resist hail up to a certain size, if that's an issue where you live. I'd suggest looking in the phone book or on the internet for a local solar installer, and asking them for references close to you. You can then contact the people there and ask how it's working out for them. Also try searching for an answer on the link below. It's a solar discussion forum with very knowledgeable people.
Q:What is the anatomy of a solar panel?
You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights. Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical systems. You have probably also been hearing about the solar revolution for the last 20 years -- the idea that one day we will all use free electricity from the sun. This is a seductive promise: On a bright, sunny day, the sun shines approximately ,000 watts of energy per square meter of the planet's surface, and if we could collect all of that energy we could easily power our homes and offices for free.
