Q:solar panel, dc light help?
3 w for 2 hours/night is 36 watt hours. You'll get about 500 watt hours/day from your panel on the average, which for a 2 volt battery is about 40 ampere hours. You can get an 80 amp-hour sealed gel cell battery to charge with this panel (with a suitable charge controller). You want to size your lights so the battery can provide three days of light without discharging it more than 50%, so that's abnout 600 watt-hours/3/36 = about 4 orf 5 lights. Cost for this system woulkd be over $500. The advantage of the self contained light is they use a lithium or nickel battery rather than a lead acid, so it can run totally dead without damage (unmlike a sealed lead-acid battery). That would be a far cheaper way to go. DK
Q:Solar power panels?
FIrst get an electrician...lol shouldnt cost too much if all the hardware is there , but depending on how many panels there are and what can... would tell you if the energy output would be worth the effort. plus one reason they could be unplugged is because they are bad . But you can repanel a new house with moderate power for about 3-5 grand
Q:What is maximum system voltage in solar panel?
System voltage is the total across the full chain of panels, when using multiple panels in series. It's what the insulation on the panel is rated to stand, to earth/ground, without breaking down. A device could have an output rating of V and still a 000V insulation rating. eg. if your 0W panel had an open-circuit voltage of 25V, the insulation is rated to stand up to 40 panels connected in series. (40 x 25 = 000V). And actually a 0W power source could be rated at 000V, if it's current rating was only 0 milliamps. (Though extremely impractical for a solar panel unit).
Q:Does the new horizons has a solar panel for it power resources instead using nuclear generator?
No solar panel, and for the reason you stated - it is so far from the Sun that a solar panel would be of little use (and a lot of extra weight) at the distances where the primary part of the mission was being performed. The power source is called an RTG. We can think of it as similar to a nuclear-powered battery or a miniature nuclear power plant. As far as I know it is not intended to reach any other star. If it does, it's power will have long since depleted - and it would take thousands of years at its current speed to reach even the closest star. Closest star: Proxima Centauri, slightly more than 4 light years away. Current speed of New Horizons relative to the Sun: 4.52 km/s That's 0.000048 of the speed of light. It would take more than 20,000 years to reach Proxima Centauri *if* it were heading in that direction (which it is not).
Q:What can you tell me about rebate incentives for residential solar panels in New York state?
Go to your state's department of revenue and enter the solar panel thing in the site search box and follow the thread to exactly what is in place in the here and now. Things seem to change on a daily basis any more.
Q:Where is the best place to get an education/experience and job in the installation of solar panels? ?
The best suggestion I can give is to call solar installation companies in your area, and ask for their recommendation as to what to do. They may recommend a technical college with an appropriate program. With unemployment rising, new jobs in solar will likely be scarce for a while. You might also inquire at roofing companies. If you apply at a solar company, and can demonstrate that you already have roofing experience, that will be a plus.
Q:What are solar panels made of?
photograph voltaic panels take power (and in all probability some oil for the plastic) to fabricate, yet that power, and the carbon footprint, is paid for many circumstances over in widespread operation, via the electrical powered energy that the panel generates. The life of the middle photograph voltaic cells is long (there are nonetheless some panels from the 970's that are nonetheless out and dealing), and contemporary panels are oftentimes warranted for 25 years, showing that even the manufacturers have self assurance in thier lifespan. yet whilst it ultimately comes time to eliminate the panels, the aluminum physique is as particularly recycled as the different aluminum, and the tempered, low-iron glass could properly be recycled, too. The plastic substrate is unavoidably solid - it has to stand up to the solar for some years. i do no longer understand what could desire to be achieved with that. The cells themselves are a intense grade of silicon, which has fee on the scrap industry. some panels are no longer made up of silicon - yet lots of the factors could desire to be recycled in a similar fashion. i'm no longer attentive to any intense panels being dumped or discarded at present. they're worth lots, even broken, that some hobbyist or surplus place will purchase them.
Q:How Do Solar Panels Work?
sunlight is collected by cells in a panel which is transefered to enrygy
Q:Are photovoltaics to do with solar panels?
Solar panels are a generic term for any type of solar collecting panel. There are two major types: Photovoltaic uses substances that turn the incoming radiation directly into electricity. Usually you have to have direct sunlight (no clouds) for this to work well. Solar thermal is also used in a lot of areas. Here the radiation is used to heat a circulating fluid (often water directly), and then that is either used directly, or it's used for heat exchange with a heat pump or a boiler system. Solar thermal can collect significant heat even on a cloudy day. So a solar panel could be made of photovoltaic panels, but it doesn't have to be.
Q:Why don't we use solar panels?
Good question. One of the reasons is the greed of manufacturing companies. No matter the profit margin of the product, they seem to want to charge so high a price that the break even point is ten years down the road, so the true savings are few. The cost of solar panels should have dropped way lower than they have by now. I believe that the political correctness of the product will tempt the manufacturers to keep the prices artificially high. One other answerer is right, the panels are very fragile, and damage would destroy the investment, so new inroads need to occur in technology to protect the panels from damage. Somewhere in the middle is a profit for the manufacturers, and savings for the consumer. I hope we find that middle-ground soon.
