Q:Any help financially to buy solar panels?
I live in Ohio so I'm not sure if this is nationwide, but in Ohio there are grants you can apply for if you're investing in alternative energy for your house. I would look into those grants if they're available in your area.
Q:where could i buy a cheap and low cost solar panel regulator?
try OKorder..i know it sounds corney but someone might be selling one, if not try your nearest hardware store? Like ..lowes..orsomething.
Q:Information on making solar panels?
Typical solar panels like Engineer describes require a lot of space. A single panel may only light a single light bulb. You may want to look into a different way of generating electricity with solar, it doesn't use a cell to turn the sunlight into electricity, instead it uses mirrors to focus the sunlight onto a pipe between the mirrors. The heat causes water or another liquid in the pipe to boil and the steam created turns a turbine that produces the electricity. It has the potential to be less high-tech, more forgiving of minor design and structural problems and more affordable. I don't know of any system that is privately available but you can get more info at the link below. They're building a full test facility in Nevada right now. You could presumably cobble something like this up on your own.
Q:what materials would you use and how would you construct solar panels enough to run a household?
Silica based solar cells are not the kind of thing you whomp up in you basement. Here are a couple ideas for solar systems you can build and install yourself. Take a 4 x 8 sheet of /2 inch plywood. Frame sides with 2 x 4's. Screw tin cans in a staggered row (checker board) pattern inside frame. The more cans the more heat you get so place them nearly touching. Paint cans and entire assembly flat black. Cover top with glass, plexiglass (best) or heavy mill clear plastic (cheapest)Place on roof. Drill 3-4 inch holes in opposing sides. Run pipe or tubing into house. Attach to small low speed fan. The black paint will absorb sunlight and heat. The air moving through box will carry heat into house. It's a cheap efficient way to help heat your home. You can vary size and shape of box to fit your roof. If you use more than one box, hook them up in series. More boxes mean more surface area means more heat. To heat water. Take a steel tank. A car gas tank works well. It is galvanized so it won't rust, is cheap, and easily available at any auto salvage yard. But you will have to flush in throughly to remove gasoline odor. A steel 55 gallon drum is easier to work with but may cost more. Paint exterior of tank flat black. Weld/glue/clamp water pipes to tank. Place on ground in area that gets lots of sunlight. Attach water supply to tank and route discharge pipe to house or appliance. Black painted steel absorbs heat from sun light and heats water. In spring and fall you get warm to hot water. In summer you get scalding hot water and in winter you get cold to luke warm water. Both of these solar powered systems are seasonal and their output varies according to location and climate, but they are very inexpensive and easy to build and provide FREE heat and/or hot water for many years with little or no maintainence.

Q:What is the working principle of solar panels?
No matter what kind of material to make the battery, the general requirements for solar cell materials are
Q:how much money do solar panels cost?
Consider installing building energy measurement first, which cost less than $200. Work out what is using the energy and if there are more efficient options. Consider co-generation which uses gas for an energy input and electricity generation and heat as an output. Use the Solar Energy Calculator to work out how much solar panel area is needed to generate the remaining power needed in you are of the world.
Q:How do you get electricity in a rainy day if you have solar panels?
Solar panels convert light energy into electrical energy with the photovoltaic process. They work best when perpendicular to the incoming sunlight and with no clouds in bright sunlight. They will work at reduced efficiency if there are clouds or rain, but as long as its not dark, they will still produce some electricity. That is one of the real problems with solar energy, as we expect to have electricity available on demand, regardless of day/night cycles and atmospheric conditions. Storing electricity is very inefficient, so we need hydro, nuclear,or fossil fuel energy to provide firm on demand energy as a base load.
