Q:How would you build a Solar Panel that can convert Sunlight to Energy, just being on your house roof?

Q:How to charge a Battery with Home Electricity and Solar Panel together?
connect the solar panel to the Battery direct during the day time that's how it works in ALL situations !

Q:how do i build a solar electric panel for my home?
you need to buy, not build. Just to put the parts together correctly requires a lot of experience, not something to be done by someone with no experience. And this is a major project, with lots of decisions before you start. how many watts? how many hours of sun do you get per day? worse case? Do you have a space to put the array where it can get sun all day with no shade? grid tie or not? how many batteries if not grid tie? if no grid tie, how long do you expect the batteries to last during a long period with no sun? And finally, how much money do you want to spend. for a good sized system expect to pay US$20k to 50k
Q:I have two ARCO M55 solar panels. What do I need to connect to a 2Volt bank of batteries.?
You can buy Solar Charger Regulators. I don't. These chargers limit the charging current to the batteries, so you do not get a full efficiency of the solar panel. They disconnect the batteries from the user side (the bulbs you use) if the battery voltage goes below a certain level (i.e. below 8V for a 2V battery), so you cannot use all the power available in the batteries, even in emergency. They introduce, at least, a 0.7V loss (diode forward voltage) between the panel and the battery. If you have SEVERAL panels and a lot of batteries, use a controller as above. If you only have one panel, insert a 5A trip fuse in line (in your case: twice the current of the panel), and a 0-20A diode in series between the panel and the batteries (Kathode side of the + of the battery, Anode side of the + of the panel). Install a voltmeter across the battery. The fuse will prevent any short or over-charge current. The diode will prevent the battery to discharge into the panel at night if it is not already protected. The voltmeter will allow you to watch the status. Your thought of limiting the voltage is useless: should the battery be low, the panel will drop its voltage, limited by the max current. Should the battery be fully charged and the solar panel at full efficiency, it will just try to charge the battery more. A bit of bubbles may result, hence the voltmeter to watch over it. If you want to limit the voltage to 4V, put a 4V Zener (4Vx2.5W!) in series with a resistor of, say, 7V-4V/2.5A or ~ Ohm, 5W, in parallel with the panel.
Q:What things can a solar panel power?
Add up the Watts, listed on the nameplate of each item, and compare that to the wattage of the solar panels, watts/square foot times number of square feet of panels. That will give you the most your panels can power if everything is on at the same time, the sun is at its brightest, and there are no losses in the system. Then you've got your storage capacity and inverter capacity to consider. If you've only got 8 hours a day of sunlight, then you need 3 times the area to cover the other 6 hours in the day. Although you are unlikely to run everything full bore all the time, neither is the sun a constant. For most people the best actual return on investment can be had by using the panels to store energy in a preheater for the hotwater tank fill line. This avoids the cost of batteries, an inverter, and an automatic throwover switch, as well as the time, trouble and expense of dealing with the power company. If you actually have energy left over, the best way to use it is to charge a battery bank connected to an uninterruptible power supply on your most used and non essential equipment, ie TV and Computers. When you are there, unplug the UPS and run your stuff on the batteries in that. I'm sure a electronic type could build dropout relay that would automatically switch the ups back to line power when the batteries start to run out. You would want to disable the inverter's charge circuit also or it would use line power to charge the batteries.
Q:Solar Panels Have Faded?
Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!
Q:will a 5v 52watt solar panel charge four 2c dv 55ah batteries?
Technically, any solar panel can charge any battery, but it would take quite a long time do do so if it is a large battery. If you are aware of the voltage and either amp or watt rating of the unit that is usually used to charge the battery, the solar panel should have a similar power output to that charger to work well. amps and watts are quite similar, and can be converted with this simple formula: W=watts; V=volts; A=amps; W/V=A; V*A=W; When charging batteries, it is always wise to use less amps than needed, and roughly the same voltage as the battery being charged. The less amps used to charge batteries means the battery will take longer to charge but will last a lot longer in the long-term. Your solar panel should be sufficient to charge the battery, but you should test charge it to see if it works well. I recommend using a multimeter to check the batteries voltage every couple of hours. Once the battery reaches 2v, it should be fully charged. You should also check the amps in case they are not at the expected value (take caution when checking amps with a multimeter, when i do it i always end up melting my multimeter leads). The battery should be fully charged from anywhere between 6-48 hours. if it is charging faster, the solar panel has too much power. if it doesn't charge in this time frame, the solar panel is not powerful enough.

Q:what do i have to study to install solar panels?
boots on the roof is one of the classes , around phoenix it it offered at rio salado college, there their so theres a place to start. I have had 2 different people check for me and from what i understand i can install the panels but a licensed electrition has to connect to the meter
