Q: If we invest billions in green energy and put up thousands of square miles of black panels that give off radiant heat couldn't that significantly cause more warming, not to mention the energy required to even make them?
Essentially, solar panels are 'warming neutral'. They absorb energy that would otherwise have heated whatever was behind them, thus have a local cooling effect. This is balanced by the generation of heat when the electricity is used to power, say, a hoover, TV, computer etc, also from 'transmission losses' through the national grid network. Good answers from Claire and Linlyons, bizarre answer from Jim! Tomcat may have a point though...
Q: I've been looking into solar panels. They are fairly expensive ($35k or so). My state has some rebates and grants available. Is anyone aware of any federal grants and rebates other than the federal tax credit? We are subject to AMT tax and can't take the credit. (Which is ridiculous, is the federal government committed to conservation or aren't they??????)
I have some panels on my house and no they are not cheap. If you look around you can buy them for around $4.70 per watt for a 00 plus watt panel, this will make them $470 or more. But you will get a first quality panel. And no I do not know of any fed. government programs for home owners. These kind of programs usually only go to large companies. And it does not look like our government is going to help seeing how the let the large oil companies keep there tax programs but refused to help solar. This just happened today when the senate voted on the energy plane. Good luck go solar
Q: I have a 500 watt inverter and battery but need solar panels to run my need. I want to have enough juice to run a computer and monitor and sometimes a 5w amp. I am not sure how much power is needed to run the computer (standard desktop with 5flat screen with an additional surround sound system) though on the side of the computer it says 5 amp but I know I used to run it and monitor and surround sound with a heating blanket on the same circuit which was rated at 20 amps. My question is that I would like to go and buy some panels (cheaply as I'm unemployed) from somewhere like Harbor Freight that would meet the need of the converter to supply enough amperage. So what size panel(s) or panels would I need to run this setup? If I am correct I think 500 watts is equal to 5 amps. Would this even work? Could I run a partial system where I could run some of the stuff to take a load off? I need to lower my electric bill somehow. Thanks!
Solar okorder in their survival discussion in the archive, this exact project was discussed at length.
Q: Ok so if i wanted to put a solar panel on my house and i live where it snows, will that be a problem? If the snow covers the solar panel will that be a problem? If so then do i have to climb on my roof and clear it off or what?
Yes, snow will reduce the amount of energy the photovoltaics recieve and convert to electricity. Because the panels usually have a very flat glass surface, and because the slope for the panels is usually fairly high, snow will often slide off. Freezing rain, esp freezing rain changing to snow can make a covering that's difficult to get off. If you don't usually get freezing rain, and if you usually have nice sun after snow storms, your panels should be clear most of the time.
Q: My project needs to build a thermal solar panel that would be used as a demonstrational rig. The dimensions i am allowed do not allow me to use a normal thermal solar panel so i have decided to use the heat exchanger from the back of a fridge. Although this is possible to use what equation would i use to prove the power of the sun would actually heat up the water. More importantly when the rig is demonstrated to students, they will need to be able to determine if the raise in temperature given by the thermometers is what should be given. Variables of the rig will include: Angle of the panel, Light intensity, Direction of panel, and more importantly the flow rate of the water travelling through the pipes. What equation includes those variables (change in temperature, flow rate) and would allow me to incorporate the angle of the panel. The light source would be a lamp so i would also need to know how much of the energy from the lamp is actually being used by the panel?
Forget the long winded discussion above. There are so many variables that you cannot calculate the outcome. This does not mean that the experiment is a failure. It gives you information on the fact that water can be heated in this manner, and that you can vary the result by modifying the variables.
Q: Can solar panels be installed in rural areas?
Yes, solar panels can be installed in rural areas. In fact, rural areas are often ideal for solar panel installations due to the availability of open spaces and ample sunlight. Installing solar panels in rural areas can provide clean and renewable energy to these communities, reducing their dependence on traditional energy sources and improving energy access.
Q: Dont/Cant work alone?when you buya asolar panel you mUST GET bATTERIES, voltage regulators and many else stuff?cant they just work directly? or can i use normal batteres like Car batteries?The one who Really knows 0 pts. thanks
You do not need batteries unless you want power at night, you don't need a regulator unless you'll be using your panels to power anything other then what the voltage of the panels is (ie 2v panel = 2v llight bulb) 3.You can use them directly or you can use car batteries (though deep cycle batteries are better).
Q: Can solar panels be installed on historic buildings?
Yes, solar panels can be installed on historic buildings. However, the installation process may require careful planning and consideration to ensure that the panels are discreetly integrated with the building's architecture and do not compromise its historical value. In some cases, solar panels may need to be installed in less visible areas or designed to resemble traditional building materials. Additionally, it is important to consult with preservation experts and local authorities to ensure compliance with any regulations or guidelines specific to historic buildings.
Q: Can solar panels be used to power a skyscraper?
Yes, solar panels can be used to power a skyscraper. Advanced solar technologies and efficient panel setups can generate significant amounts of electricity, making it feasible to meet some or all of a skyscraper's power needs. However, considering the high energy demands of skyscrapers, a combination of solar power with other renewable sources or grid connection is often employed to ensure a reliable and consistent power supply.
Q: I don't remember what number exactly but it's in the single digits. This number represents how efficient solar panels are at capturing the sun's rays and converting it into electricity.Why?
There are a lot of solar panels available today's. The problem of the efficiency is the proccess of converting, these cells use the photons of the sun to react with the ( Si compound inside the cell) due to the little thing that cell's are only a fraction of these energy is converted, remember that solar cells are paper thin and the really problem of these cells are the voltage not the amps. A single 3x6 inches solar cells can produce 3.6 amps but only 0.5 volts.
