Q:how are solar panels practical?
Solar panels are comprised of several individual solar cells. These solar cells function similarly to large semiconductors and utilize a large-area p-n junction diode. When the solar cells are exposed to sunlight, the p-n junction diodes convert the energy from sunlight into usable electrical energy.
Q:solar panels?
answering b) your home circutry won't be able to handle solar power energy (or your circut breaker,it will start cuttin out every 5 min)you would have to replace your home circutry(that costs a LOT of money, over $8500)
Q:How do solar panels and their battery backup systems work?
First, you didn't say the voltage. Second, 30 W/hour per day. Third, battery backup capacity in Ah = Ampere hour. For 2 Volt DC here's the calculations : 30 w/hour means = 0.83 or rounded Ampere hour. You know peak time 5-7 hour (let say 6 hour)charging time (collect the sun energy). Ampere hour per day (24 hour), with 20 Ah Battery backup is OK. And the Solar Panel is 3 Ampere charging capacity minimal = 3 Amp x 6 hour = 8 Amp hour.
Q:if you put solar panels on cars, you'll be able to drive without gas in the summer and part of winter?
Yes. But you won't be able to go very fast. If you fill up the roof, hood and trunk lid of for example, a Toyota corolla, with the most efficient solar panels you can buy, you might get 2 hp in the mid day sun. That could push the car maybe 2 mph on a flat, and wouldn't get it up a hill unless it had super low gearing. In order to go fast enough on solar power to make it worth while, you need a large area of solar panels and a super light car. Like an aluminum tube frame with a foam and fiberglass composite body, skinny, high pressure tires and a solar array 6 ft wide by 2 feet long. A car like that, with good aerodynamics and a 6 hp motor could get up to 45 mph eventually, just slowly. But it's impractical because it's not safe to drive it with other cars around. But who says the panels have to be on the car? If you have a solar array that feeds as much power into the grid as you take out, that is essentially equal to being solar powered in all practical ways. Even if your car can't be entirely solar powered, that don't mean you shouldn't use solar panels. You could use solar panels in any car, to supplement battery charging, taking load off the alternator, and you would see an increase in fuel economy. There is a system on some cars that uses solar power to circulate air through the cabin when the car is sitting in the sun. This keeps the car up to 30 degrees cooler, taking a huge load off the air conditioner, so instead of pumping all that heat out, you simply vent it into the air, and there is an increase in fuel economy for a few minutes. Every little bit counts.
Q:Does anyone know a company that will make custom solar panels?

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.
Q:Solar panel wiring, materials?
the solar panel should state it, you dont need a inverter to charge, only to use the power from the cell.you do need an amp regulator, so it tells if the battery is on full charge and so the sun doesnt over power the battery through the solar panel
Q:Solar panel, Home office and Tax write off?
The solar panels are a capital improvement. You can deduct 5% of the depreciable portion of the property as part of the home office deduction. You'd have to depreciate the solar on the same 39 year straight line schedule as the house itself. (The land value is never depreciated so you'll have to break that out separately.) Since this is business use of real estate, the depreciation is over 39 years, not the 27.5 years for residential rental real estate. That crunches out to a whopping $38 deduction per year for the depreciation on the solar panels. ($0,000 x .5) / 39 = $38.46 which rounds down to $38. If you're in a 25% tax bracket, that will save you a whopping $0 in taxes. Keep in mind that when you sell the home, the depreciation allowed or allowable will be subject to recapture. That is taxable income subject to a maximum tax rate of 28% even if you can exclude the gain on the sale under Section 2. For that reason you might wish to consider the safe harbor deduction new for tax year 203. You may deduct a flat $5 per square foot up to 300 square feet for a maximum deduction of $,500. That won't trigger the depreciation recapture (for the years that you use it, you can switch off year for year if you wish) and may reduce the likelihood of an audit as well.
Q:Where to get solar panels in Birmingham, AL?
Any electrical contractor could likely install them, and there are several Internet businesses that sell solar panels. You likely have no place there to get the kind of large panels you need for a house. Look at your local regulations. Your utility may not allow grid-tie, so you may have to set up an off-grid system with batteries and use separate wiring or a transfer switch. One thing a lot of people neglect is hail protection. In Birmingham, you're likely to have large hail (larger than golf ball size) every couple of years in the spring. You need to work out a way of covering them in advance of severe weather. Most panels will take up to golf-ball size hail with no problem. DK PS, I've done this myself, and have considerably more information. Email if you're interested.
Q:solar panel help needed ?
You need to know how many solar cells are in the panel and what is the rated current each cell will produce. This information should be listed on the panel. Each cell will produce from 0.5 to 0.55 volts DC per cell and each cell will produce a current that is dependent on the size of the cell and the type of material the cell is made from. If the cells are connected in series then the voltage of each cell will add together, that is if you have 30 cells connected in series they should generate about 5 to 6.5 volts DC. If each cell generates .2 amps, then you multiply the voltage of 5 volts DC times .2 amps DC equals 8 watts of power. The current of each cell does not add together when you connect the cells in series only the voltage of each cell. If you connect the 30 cells in parallel then the current of each cell adds together but the voltage of each cell does not. That is 0.5 Volts DC times 36 amps equals 8 watts. The power (watts) produced will be the same. See our blog on the products page to see how to connect solar cells in series and in parallel. We also have a PDF file of solar cells and their rated output current sorted by watts per area and their manufacturer.
