Q:how much watts can a x2 inch solar panel make?
Did okorder.com/ . Possibly this could immediately instruct each and every one!
Q:Solar Panels: How long will it be before solar panels are cheap & effecient enough so that everyone?
Solar panels are cost effective if they are used over their payback period. The problem is that the down payment is expensive, and the payback period is maybe 0-20 years, so very few people actually expect to own their homes for 0-20 years. It also only really makes sense in areas that buy back electricity generated during the day when you're not using it. In Germany and other european countries, power companies are required to buy back electricity at a higher price than they sell it for--this reduces the payback period and is a great incentive for solar panels. For this reason, they are much more popular over there. Given a little time for the price to fall and given some change in energy policy, solar panels will become more cost effective in the future. Depends on who gets elected, though. There is a solution to the payback period problem, though. Rather than homeowners taking on the long payback period in homes they may not own long enough, some companies are buying panels and leasing them to homeowners. In exchange, homeowners get reduced electric bills, that pay off the lease payments, plus a little extra. I think this is the way to go. check out the link below.
Q:How much would solar panels cost for these?
They would cost quite a bit but the user would likely be eligible for some energy credits from the power company and their cell phone carrier which would bring down the costs
Q:How many Watts of solar panels?
whenever i do my gf, i use up to 900 watts of power
Q:How can I make a sun tracker for a solar panel?
tbls0 has a good idea for the tracker, but let's take this one step farther. A clock motor large enough to move a solar panel, unless it is a very small one is going to be large, and expensive. Use the timer motor, as suggested, but attach a slotted disk to it, with a light source on one side, and a detector on the other side. As each slot comes up and allows light to pass through, this creates a one shot pulse which is used to cause a stepper motor to move position to keep the panel aimed at the sun. At the end of the panel travel for the end of the day, a switch could be set to close, bypassing the step control to put the motor into full constant speed reverse, this causing the panel to swing back to the morning position. The whole affair gets it's start up call by means of a light detector, similar to those used to turn lights off at sun up. The control would, of course be set to turn the system on to track the sun during the day. While some digital control is going to be needed, the system would not need a computer to run it.
Q:architecture and solar panels?????????????
They aren't considered attributes - electrical solar panels are expanses of gray and aluminum covered with glass and water heating panels are expanses of black covered with glass. To cover the cost of investment they must be mounted at the best angle for the location and climate throughout the year and therefore may dictate the form of the roof (if sloped as on residences) or may not be visible in an architectural sense (if positioned on a flat roof of a commercial building.) No matter where placed, provision has to be made for safely accessing them for repair and maintenance.
Q:Can I plug a solar panel into a wall socket to lower my electric bill?
The other responders have given partial information. The electricity in your house is 20 volts AC and the solar panel will produce DC voltage. If you plugged in the solar panel into the wall, the solar panel would be destroyed, possibly with disastrous results. If you connected the solar panel to a DC to AC inverter, there are also dangers. The solar panel unless very large will not produce enough power to make a lot of AC, for every amp of 20 volt AC, you require more than 0 Amps of DC voltage. So most small solar panels are used to trickle charge a 2 volt battery used in backup situation. The problem is that the house AC and the inverter AC have to be exactly in phase or again you have disastrous results. If they are exactly 80 degrees out of phase, the wires now are carrying 240 volts and you will burn out the inverter, and possibly cause a fire. There are systems that will synchronize an inverter to commercial power so that you can feed the power back to the grid, but these are more complicated. If you want to use the battery and solar panel to run some lights during power failures, then you can connect the light to the common terminals of a switch, but the switch must be a break before make switch, which means that when you throw the switch the common is disconnected from the one source before it is connected to another source. Most AC switches will do this, but make sure.
Q:How do you install solar panels?

Q:how to store energy from solar panels?
If you are buying a kit, chances are there is an instruction manual in there on how to mount your solar panels. You can also ask for assistance from the store.
Q:Solar panel question
The answer is actually quite complicated, but if you're planning on building just a very small system, most likely, the panel will be small and weak. In this case, connecting a panel that is 8 volts open circuit directly to a lead-acid battery is probably the most efficient way to charge. There are charge controllers that you can buy, some of which actively track the maximum power point for charging your battery. Unfortunately, those controllers might eat 5 or 0 watts, just to get you another few percent of charging efficiency. If your panel is only 50 watts in the first place, you can see that this is not a good deal. If you're getting serious panels (clue: price $500 each), then you may very well benefit from a charge controller with MPPT (max power point tracking). Lead-acid, either a flooded cell like your car battery, or AGM, are the standard for solar energy storage. Lithium ion is better in many ways, being less sensitive to temperature, state of discharge, and they are also lighter. Charging them is also more straightforward with the right circuitry. The problem is, they cost like $500 per kWh, compared with less than a tenth that price for lead-acid.
