- Q: We are considering getting solar panels for our home just south of Birmingham, AL. We know a little and are trying to educate ourselves the best we can. But we are having a hard time finding anyone around this area. We have done the yellow page thing, and some quot;green places around town. But to no luck.....
- 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: Why can't they put solar-panels on the blades and sides of the 300-500 foot tall turbines? Wouldn't this increase effeciency? Therefore, boosting pay-back time, profits, energy-output?
- Good to know someone is thinking and coming up with original ideas, so thanks for contributing... Put a large powerful solar collector on the end of the turbine too i.e. facing the sky! Far as I know, solar works on day-light (doesn't have to face the sun). So your idea is not to be put down. Metal blade turbines - are heavy - wooden windmills - heavy... so some added weight to the wind-turbine's paddles would be OK robably. Great if solar device not made of glass (so unbreakable). I think panels on the roof are old hat...
- Q: I contend:As far as the solar panels causing global warming I'll try to explain. If you put a black panel on the ground or on your house and don't connect it to anything, it will absorb solar energy (heat) during daylight and release it at night (radiation). The net heat gain is zero. If you hook up a solar panel in the same place but hook it up to batteries, charge the batteries during sunlight hours and using that energy to electrically heat the home at night. The panels will absorb solar energy during the day but will convert that to electrical energy in the batteries instead of radiating it back into space at night. The result is a net gain in earth's temperature.Right or wrong?
- Solar energy is very inefficient, and so most of the sunlight that is absorbed by the solar cells is re-radiated back as heat. But that leads to a bigger point. Global warming is the ability, or inability of the Earth to radiate heat/light out past the atmosphere into space. Once the light reaches the surface and is absorbed, it doesn't matter whether it was by a black panel or a solar panel. Energy is energy. A black panel does not radiate energy into space, it emits it into the atmosphere. The use of electrical energy also generates heat which is transferred to the atmosphere sooner or later. The advertised culprit of global warming is atmospheric greenhouse gases like carbon dioxide, that reflect infrared wavelength energy from the surface back down to the surface. The heat generated by sunlight on a black panel, or from the use of electrical energy, is reflected back by the greenhouse gases instead of radiating out into space, no matter what the source. So no, solar panels do not contribute to global warning simply because of their transfer of light into electricity instead of infrared/heat. The source of the heat (black panel or electrical use) is not the (whole) problem. It is the greenhouse gases that trap the heat that is the problem, according to the global warming theory. I hope this helps.
- Q: Can solar panels be used to power an entire office building?
- Yes, solar panels can be used to power an entire office building. By installing a sufficient number of solar panels on the roof or in a separate solar farm, it is possible to generate enough electricity to meet the energy demands of an office building. Additionally, advancements in solar panel technology and energy storage systems make it more feasible to rely solely on solar power for an office building's energy needs.
- Q: does it mean that it can get that much in a day? Or like, in an hour?
- watt is a measurement of energy watt=3.4 BTU BTU(British thermal unit )=amount of energy to raise pound water degree f. us gallon water = 8.33 lbs can gallon water = 0 lbs depending if 0vac then a solar panel can light a 00 watt bulb or 6 5watt high efficiency bulbs
- Q: i want to instal solar ligth in my garden
- hello, okorder /
- Q: How to Compare Solar Panels? ?
- The short answer is nobody does. Solar panels just generate electricity and only when the sun is shining. What you can do however is sell the electricity you have generated to your local power company. Computer solar panel for using computer and how much volt support?
- Q: i am starting to consider getting solar panels instead of paying electric bills which are somewhat higher now than they used to be
- Solar power is expensive power. The costs have been coming down but unless it's the only option or there are government subsidies, it would still be less expensive to buy electricity from the grid. The way you compare the upfront costs of solar power with monthly bills is by the Internal Rate of Return equation or the Net Present Value calculation. Vendors will use the payback periods to try and convince you into a financial decision where they reap all the benefits so you need to learn how to do a proper financial analysis. The average US household uses about 950 kwh per month, unless you are very wealthy, you will not be able to afford enough panels for that and you probably don't have enough roof space. You will have to reduce your power usage as much as possible. Batteries are expensive and inefficient. Lead acid batteries are 95% efficient at discharging but only 50% efficient at charging. A battery based system would not only include the costs of the batteries but would also double the number of panels required. Lead acid batteries have their lives rated at only 20% draws on their capacities, they lose a lot of life with each deep cycle. There are deep cycle batteries which have thicker plates but they are also rated at 20% draw and a deep cycle battery's life would drop to 94% with just one deep cycle draw. This means, it's customary to buy five times your diurnal capacity worth of batteries, fortunately this allows for several cloudy days. If you do want to have deep discharges, buy Nickel Iron batteries. You will want a grid tied system instead where you sell the power you produced to the utility and buy back what you need effectively turning the grid into a 00% efficient battery. Of course, there are costs involved as the utilities would likely charge a monthly fee just to be hooked up so this cost must be taken into account. There is also the risk that the utilities may change their net-metering arrangements on you later.
- Q: I am looking at a need of roughly 30w/hour need per 24 hour period. I have spent several hours now looking for information online and have found plenty of info regarding the panels themselves, but information regarding the batteries backups have been slim. I understand that there is a 5-7 hour peak time to collect the energy. I am looking for information regarding the batteries themselves. How do the batteries work, what size batteries should I look for, and what is the life expectency for the batteries? Any website links would also be appreciated!
- The photograph voltaic panels in straight forward terms produce any potential whilst the sunlight is shining. they can't furnish any potential at night or whilst it somewhat is cloudy or wet. The panels can in straight forward terms can charge to the batteries the surplus potential you're no longer using for the period of the easy sessions. The Battery financial business enterprise ought to be sized such that it will furnish all of the potential whilst the sunlight isn't shining. In some factors the place you have distinctive cloudy days, the battery financial business enterprise ought to be very great. The photograph voltaic panels ought to be sized such that they are going to furnish all of the potential you have chose during sunshine cases, PLUS adequate extra to can charge all of the batteries adequate which you might have potential for the period of the night and cloudy cases. My buddy in Mexico has a stand on my own gadget for his domicile because of the fact there is not any grid potential obtainable the place he lives. He has invested over $50,000 and nevertheless ought to run his back-up generator some. He lives in Sonora desolate tract the place the sunlight shines all of the time. He has sixteen photograph voltaic panels and 24 of those golf cart batteries, plus a 0KW back-up generator. He could elect to have grid potential!
- Q: Can solar panels be used in areas with high humidity or saltwater exposure?
- Yes, solar panels can be used in areas with high humidity or saltwater exposure. However, it is important to choose solar panels specifically designed for such environments, as they need to be corrosion-resistant and have proper sealing to prevent any damage from moisture or saltwater.
