Q:Do solar panels shine/have luster? Please help me. Easy ten points!?
Solar panels reflect less sun than a piece of window glass, and people aren't harmed by the sun's reflection off windows. Also, solar panels tend to be tilted more or less directly toward the sun, so the light that they reflect is back at the sun, not down into the street or yard where people are. Those huge power tower concentrating solar thermal plants have a brilliant light reflected off the boiler. But those are put out in the desert, away from people.
Q:advice what solar panels to purchase?
If all things are equal buy local. If you are building for a LEED project then choose a manufacture within 500 miles. Another reason to choose a local panel is that if things go wrong there is a better chance of a satisfactory resolution. A no name knockoff from overseas might prove to be difficult to find a few years down the road. One good place to check is the Go Solar California website. They have proof of performance testing on hundreds of panels.
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:A Question about Solar panels?
You are missing one bit of information in order to get an answer. Watts = Volts x Amps Find out how many amps the collector can put out and you can then plug in the numbers into the equation and get your answers.
Q:Why are solar panels still so expensive?
materials and process... if they could be built in a sweatshops, by kids, in Malaysia, they'd be cheap and everyone would use them
Q:explanation of solar panels?
You'd better build some sample project. For e.g, if you mean solar water heater, install one pc on your roof, and make it generate hot water, and tell people about it.
Q:Solar panels........................?
If your purchasing solar panels for a building or colony where a few families live together, the cost of the panels can be distributed or shared. And loan and electricity bill wont be the same. Loan is a one time transaction while electricity bill you have to pay monthly and everytime. You dont have to buy solar panels every month lol. So its a better option to spend on solar panels although it maybe a big amount, rather than paying high bills every month....
Q:have you ever installed solar panels for your home?
Yes I have. We have a little Labrador on the front steps(you know, a thing to hide keys under.) In his mouth is a little lantern that absorbs the solar energy from the panels and it turns on at night. Really saves you money, much more than regular electricity. The bill won't be so high this way, oh, and it's also good for the environment����
Q:Solar Panel Watts?? help!?
200 Watt Solar Panel
Q:Why only Photo-Voltaic solar panels?
That sounds good to me. I'm all for any kind of new energy as long as it's renewable and doesn't pollute the environment. I'm even a fan of solar water heating.
