- Q: The Physics club in our school is trying to convince the Board of Ed to install solar panels in our school, and i was just wondering if anyone with some experience or real expertise in solar energy. I need some points about their usefulness some real pros and cons on maintenance, etc. Anything will help. Personally i would be perfectly for the idea, but i heard that the overall cost of installing them is much higher than the cost of the energy saved and government subsidies, but ive only heard about this.

- Q: Hello, I have been trying to go green, I Have purchase somesolar panel they are about 45watts I been putting it against my window and getting ok power out of it enough for my lights and a couple of low watts gadget (cellphone, 2v light, portable dvd) for couple of hours.But its seem to drain the 2v faster then I can charge Am I getting the most power out of my panel?Or should I place it on the roof? I'm in Texas and it gets hot and sunny the sun beam my room windows pretty good during 4pm-6pm.
- outside is going to be much better. You can't tell but glass is actully opaque to many ranges of 'light'. If you look at advertising for windows you may see claims to reduce sun fading of your carpet/ furniture. That is because the glass blocks UV. Solar panels get some of their energy from UV light. Also some windows are engineered to block IR to help insulate better when the house is cooler than the outside. Again, solar panels get some of their energy from light in the infrared range. And finally if you're charging batteries the 'off angle time' is still important. The amount of light absorbed is pretty closely related to the cosine of the angle that the sun is 'off' of the direct. so when the sun is 45 degrees off of perpendicular the panels still get cos45 =.707 or about 70% of the available energy. (In practice it's a little less than that because not as much energy gets to the panel to be absorbed as at midday). But anyway, you can figure two hours of morning or late afternoon sun will give you as much energy as hour of midday sun. So if the panel is inside, you miss out on that available energy.
- Q: How do solar panels perform in extreme temperatures?
- Solar panels can still generate electricity in extreme temperatures, but their performance may be slightly affected. High temperatures can cause a decrease in efficiency, as the heat reduces the panel's ability to convert sunlight into electricity. However, modern solar panels are designed to withstand a wide range of temperatures, and their efficiency losses are generally minimal. In extremely cold temperatures, solar panels can actually perform slightly better due to the improved conductivity of the solar cells. Overall, while extreme temperatures can have a small impact on solar panel performance, they are still a reliable and efficient source of renewable energy in various weather conditions.
- Q: ok im going off grid and will have my fridge and stove running on propane but im trying to figure out that at night i want to be able to run my 32 inch lcd tv a internet modem a playstation 3 and 2 laptops and a light or 2 and maybe a floor fan through solar power and i would like to be able run my tv and stuff up to 8 hours in to the night and so i just want to know how many batterys and solar panels i need or how many watts system do i need im running all this on one outlet now at home so i know its under 20 amps and i think i use about 000 watts an hour im not sure so thats why im asking i really need help with this i hope i dont need a $5,000 system thats crazy im only wanting to spend like a $000 please dont explain math figures or a bunch of complicated garbage to me i just want a straight answer on what i need to do to be able to do this thank you!
- Buy a device called a kill-a-watt to measure exactly how much power you use. If you get a systemt to put out 000 watts, it's going to be more than you need, and you'll waste your money. 20 amps is 2200 watts (assuming a 0 volt circuit), which is even more. That will be very pricey. Get the kill-a-watt so that you don't spend more than you need to on solar panels. The cost of the kill-a-watt is almost nothing compared to what you'll be spending on the panels. If I had to guess, 500 watts would run all those devices at the same time.
- Q: if u buy solar panels and never take em out of the box for like thirty years will they still work good thirty years after you bought them
- I'm answering for conventional silicon solar panels, the only kind I really know. The panels are basically semiconductor, wire, glass, and aluminum housing. The last three, everyone knows have long lifetimes if not exposed to the elements. As for the semiconductor part, the degradation is generally due to exposure to the sun. And even so, some solar panels from the 70's are still working today. Usually, what does them in is failure of a connection due to vibration, degradation of the plastic due to heat, sun, or water exposure, or accidents. The question of how useful the panels would be after 30 years is different, though. I have Germanium transistors from 50 years ago - they're still good, but their specs are really lame by modern standards. And suppose you had a PC from 25 years ago. Original cost, $4000, no hard disk, only runs DOS off a 5 /4 floppy disk. It works great, but except as a curiosity, is it useful? The batteries that most people use to store solar energy are lead-acid. The technology has not changed much in 30 years. If you had such batteries in storage, that had *never* been activated (that it, they were dry, no acid had been added yet), I would not be surprised if they would be fine after that period of time. If the batteries were activated, no, they would not keep. But maybe battery breakthroughs are coming with other chemistries, so those batteries would seem clunky and useless 30 years from now.
- Q: Do solar panels require cleaning?
- Yes, solar panels do require cleaning. Over time, dust, dirt, leaves, bird droppings, and other debris can accumulate on the surface of solar panels, reducing their efficiency. Regular cleaning is recommended to ensure optimal performance and maximize energy generation.
- Q: Are there solar panel systems that I can plug directly into my house to help reduce my electricity bill? If so, are they very expensive? Any help would be greatly appreciated!
- I wish it was that easy! Maybe it will be soon. But at this time, no, there isn't. And if you have a solar collection system, you have to have a way to store the energy when you're producing more than what you are currently using. That usually involves an expensive battery array. But it's necessary. The power coming directly from the solar panels will be erratic and sending it to the battery array for storage and then use allows for the home to draw a consistent level of power. And this battery system also allows for storage of electricity for use when the sun isn't shining like at night. The system should be set up to use your power first, then go to the grid. It should also allow for distribution to the grid when your system has stored all the power it can and that's when your meter will run backwards and the power company will be paying you! There are a lot of federal and state income tax rebates for alternative energy installation costs. Check out what Oregon might toss into the package along with the Feds and see where you might come out.
- Q: What is the difference between on-grid and off-grid solar systems?
- On-grid solar systems are connected to the local electricity grid, allowing excess electricity to be fed back into the grid and potentially earn credits or payments. Off-grid solar systems, on the other hand, are not connected to the grid and rely on energy storage solutions, such as batteries, to provide electricity when solar production is low or during nighttime.
- Q: Can solar panels be used in areas with high levels of heatwaves?
- Yes, solar panels can be used in areas with high levels of heatwaves. In fact, solar panels are designed to convert sunlight into electricity, and they perform better in areas with higher levels of sunlight and heat. However, it is important to consider the impact of excessive heat on the efficiency and lifespan of solar panels. Proper installation, maintenance, and cooling measures may be required to ensure optimal performance in areas with extreme heat conditions.
- Q: Does any one know how to make a solar panel or a type of Alternative energy maker. Best answer gets 0 points
- shows some solar cookers. These might be usable instead of a barbeque grill.
