Q:how many solar panels needed for Heater and AC?
There are many, upon many variations of equipment needed for a complete solar home. I would call several contractors in your area that deals with it and get estimates. You have to look at what your wattage diet is at your home. How many watts are you using for your AC and heat. Which can vary by age, efficiency, insulation of home, etc. Look at your electric bill for a normal summer month and a normal winter month, then estimate your heating and cooling (Sometimes can be as much as 70% of the bill). You will see on your bill your toal kilowatt hours. ( Kilowat = 000 Watts) Solar systems can start as low as $2.00/watt, but can rapidly approach $20.00/watt depending on the difficulty of application etc.... Here is the great thing, in many areas of the country there may be rebates from the county or state. And what you don't use can be fed back into the grid, and you get paid for it. But as always - Call a quailified contractor and get the right system for your home.
Q:How much do solar energy panels cost?
I co own Sunpower Solutions. We are a solar company in South Jersey. I can tell you that the average cost for a system under 7Kw, is $7.95 per watt. What people fail to realize, is that there is a lot more that goes into a PV system than just panels. Racking, hardware, combiner box, inverters, labor to put the panels up, pay the electrician that ties it all together, the architect that measures the wind load on the panels, etc. It's not cheap. Although, in the state of NJ, the the amount of time it takes for the system paying for itself, is 4 years. It doesn't matter if it's a huge system or the smallest PV system, it's 4 years. Any questions, just ask. @Martin: The thing with those programs, is that the company that is leasing the system, is taking advantage of the renewable energy credit that the system is producing. Yes you get cheap electricity, but you are not taking advantage of the money making ability of the renewable energy credits.
Q:Electricity question about solar panels?
You will have to run the solar panel to a 2v or 24 v battery array that use an inverter to convert the battery power to 20 for the heaters.
Q:Can you overload solar panels with too much light?
Solar panels have a upper temperature limit, and it's only a bit more than it would reach in a very bright sunny day near the equator. Start shining heat lamps on it and you will raise it past it's max temperature, and it will die. .
Q:How much is the average solar panel?
You are way out of your depth if your report for science class is supposed to be knowledgable. First of all, Solar panels alone will NOT be enough to charge the battery bank, which you don't even mention in your quesiton. Secondly, the only way to have a usable 2 VDC system is to use a wind generator to keep the batteries charged to capacity and, as a plus, they will work at night. A 65 Watt ARCO Solar Panel is about $300 and you need to figure your power by the Wattage Rading for the particular panels . You also need to add in the cost of a 2VDC to 0VAC invertor, monitoring panels etc.... AND... just how big is the ROOF of the house you are planning to use.? This is an area of involved study and it's a bit more than what you are imagining for your high school science class report.
Q:what is a solar panel?
The term solar panel is best applied to a flat solar thermal collector, such as a solar hot water or air panel used to heat water, air, or otherwise collect solar thermal energy. But 'solar panel' may also refer to a photovoltaic module which is an assembly of solar cells used to generate electricity. In all cases, the panels are typically flat, and are available in various heights and widths. An array is an assembly of solar-thermal panels or photovoltaic (PV) modules; the panels can be connected either in parallel or series depending upon the design objective. Solar panels typically find use in residential, commercial, institutional, and light industrial applications. Solar-thermal panels saw widespread use in Florida and California until the 920's when tank-type water heaters replaced them. A thriving manufacturing business died seemingly overnight. However, solar-thermal panels are still in production, and are common in portions of the world where energy costs, and solar energy availability, are high. Recently there has been a surge toward large scale production of PV modules. In parts of the world with significantly high insolation levels, PV output and their economics are enhanced. PV modules are the primary component of most small-scale solar-electric power generating facilities. Larger facilities, such as solar power plants typically contain an array of reflectors (concentrators), a receiver, and a thermodynamic power cycle, and thus use solar-thermal rather than PV.

Q:Where can i find a list of solar panel manufactures worldwide?
You can't buy at that level unless you are connected to governement. A lot of production is already spoken for for years to come. Where you live determines what you can legally buy and install. The EU has it's own certification, the US has 2 sets, the Canadians have their own. Your answer also requires knowing the use for the solar panels, whether it is grid-tie, off-grid or standalone to power an appliance. And you have to choose mono crystalline, poly crystalline, or thin-film.
Q:How to amplify current from a solar panel?
If you want to power both USB ports at the same times, It might not be possibble. Your solar panel only supplies 2.24 Watts (20V * 0.2A) of power and you need to deliver 2.5 Watts (5V * 0.5A) to the ports. Subtracting any losses from your regulator(s), you will be WAY over your power budget. You will need more of a solar panel or less of a load.
Q:Can solar panels be connected directly to motor?
If the DC motor, solar panels generated by the power through the controller, and then can be used; for AC motors, solar cells to the power through the controller and inverter (DC into AC), and then can be used.
Q:Can I plug a solar panel into a wall socket to lower my electric bill?
You're quite right that the solar panel can't be directly connected. I sense that you want to start small, but unfortunately, it's hard enough to make a system with a dozen or more panels pay back. (It can, we have a system...) But with just one panel, maybe a small one, the economy of scale is gone. You need to buy a grid-tie inverter, which watt-for-watt will be more expensive than a regular size one, and for a small panel, the $$/watt value will be poor. There are some [illegal in most places] tiny grid-tie inverters that I see advertised on the web from time to time, with an ordinary plug that goes into the wall. Those are generally against electrical codes, and the danger is real. There is also a crop of micro-inverters being sold by companies such as Enphase. These are legitimate products, but will still be costly per watt, and ultimately, it will be hard to have a net savings over time with just one panel. Have you already taken the conservation steps like LED light bulbs, efficient appliances (especially refrigerator), insulation, and using a power strip to turn off loads that are not being used? That stuff isn't sexy, but saves money fast.
