Q: I thinking of buying a few solar panels, can anyone who had bought solar panels or sells them give me a price for them. I dot wanna over spend on them...
that's going to run a a hundred watt gentle bulb as long because of the fact the sunlight in shining. Or in case you had 8 hours of sunlight shine on the panel stored in a battery you may get 8 hours of light at evening (if the device replace into a hundred% effective which it heavily isn't) you will get approximately 5-6 hours of light from the a hundred watt gentle bulb. In 0 hours of light you will get kwH. So if the capacity business employer can pay you $0.0 for each kwH that's going to take 60,000 hours of light to get returned you $six hundred. approximately 20-30 years.
Q: Can solar panels be installed on hospitals or healthcare facilities?
Yes, solar panels can definitely be installed on hospitals or healthcare facilities. In fact, many hospitals and healthcare facilities around the world have already embraced solar energy as a sustainable and cost-effective solution. Solar panels provide a reliable source of clean energy, helping these facilities reduce their carbon footprint and dependence on traditional energy sources. Additionally, solar power can contribute to long-term cost savings, allowing hospitals to allocate more resources towards patient care and medical services.
Q: I need to build a battery array to use with my solar panels I just bought. I want to be able to store enough energy to be draw from it at night, possibly around the clock. Is there a down side to using the deep cycle battery I bought from autozone and 6 or 7 more just like it, or do I need to get some other battery?
There are batteries particularly made for solar, such as the Trojan T05-RE . I think the RE stands for renewable energy. A deep cycle battery should work all right, although not quite as well. What you want to do is try out your setup first, with just one battery, and the panels provided. If this is one of those 45 watt kits, you may be surprised at how little energy you actually get from the panels. Increasing the number of batteries won't help, either - that's like getting a larger water tank, when you only have a trickle to fill it. If your goal is really to save money, the most cost-effective solar is the grid-tied type, with no batteries at all. That's what we have, and I've never regretted it.
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: in the afternoon sun heat increases to high level due to which the panels heats up very high now my question is this heat will effect the panels life time and will damage the panels or not ??
Some are better than others. It depends on the manufacturing technique. All will degrade over time, some over decades, others over months (if they're defective).
Q: I'm curious, for those who have had solar panels installed on the rooves of their houses:How much did you pay? How much energy do the panels produce? Did it dramatically cut down on your electricity bill? Was it worth it? Thanks!
I say yes, I had a system put in a few months ago. I paid $6K and my utility paid $0K. I should break even in about 6 years. The system is guaranteed for 25 years, so I will have at least 9 years of free energy. I went from a bill of around $200 per month to under $20 in the summer. I will pay a little more in the winter months because less daylight, but I don't use as much energy in the winter. Each year electricity goes up an average of 5%, so while my neighbors have a larger bill each month, I'll be staying under $50 for a long time. Even without the rebate I would have a break even time of about 0 years, still 5 years of free energy.
Q: how much energy does a kilowatt solar panel produce in a year? (average)
You would be amazed how often I have answered this question. The answer is that it depends on your latitude and local weather . Let's see if I can give you enough information so that you can determine the answer for yourself. A kW solar panel is rated at kW when it is exposed to a solar flux of kW/m^2 (called a peak sun hour). There are readily available tables of effective peak sun hours per day by city (see Reference ). Let's use Fairbanks, AK as an example (it is the first line of the table). Fairbanks get an average of 3.99 of peak sun hours per day on average. So your panel would produce 3.99 kW*hr per day on average.
Q: What specification of solar panel would I need to power a laptop every day? I would need to use it for about 0 hours or so every day. I don't know anything about solar panels, but I am seriously thinking of getting one now and don't know who to ask.
Ive been employing the comparable photograph voltaic panels for 5 years, have flow some instances so as that they final lots longer than the roofs weve had over us. i'm coaching my young ones a thank you to construct wind turbines, because of the fact we shop having potential failiures whilst the wind blows. and recently its have been given very windy. I can charge banks of battery's and shop my place of work working from dc-ac converters.
Q: I have to show in a project (a model house) how Solar Panels work. In my model I want to show Solar Panels creating electricity to power a T.V but I need to show how the power gets from the Solar Panels to the T.V. A diagram would be really helpful. Please try and make this as simple as possible as I'm only 3, but try and be specific as well!
A solar panel is a device that collects and converts solar energy into electricity or heat. It transfers energy from the sun into electricity or heat which can be used by (for example) nearby buildings. Solar panels can be made so that the sun's energy excites the atoms in a silicon layer between two protector panels. The atoms split up and the electrons travel down wires into the home for electricity. Solar panels were in use over one hundred years ago for hot water heating in homes. Solar panels can also be made with a specially shaped mirror that concentrates light onto a tube of oil. The oil then heats up, and travels through a vat of water, instantly boiling it. The steam created turns a turbine for power. []
Q: Can solar panels be installed on military bases or installations?
Yes, solar panels can be installed on military bases or installations. In fact, many military bases worldwide have already implemented solar energy systems to reduce their dependence on fossil fuels, lower greenhouse gas emissions, and enhance energy security. These installations not only help save costs in the long run but also contribute to a more sustainable and resilient infrastructure for military operations.
