Q:Do solar panels add to global warming?
One piece of technology: Hydro-energy storage. Pump water up to an artificial lake at the top of a mountain to store energy, and then let the water run down through turbines to retrieve the energy later, eliminating most or all of the need for batteries. Usually this stuff saying renewables suck is BS when you actually try. Yet another method, are solar power towers which last longer than solar panels and continue to generate energy at night. While a non-universal storage method, it's good for storing the sun's energy in the mechanism that generates the power. According to some studies, they are the best option next to wind turbines. I'll describe a particular model. A field of mirrors beams light to a part of the tower which contains salt, for it's incredible heat storage capacity when molten. In turn, the heat from that region heats water which spins some turbines, generating lots of energy. Currently, the best models continue to generate electricity at night and for a few consecutive cloudy days. I think whoever was saying that was probably trying to delay response. There are too many ways around that to be true, and saying that it contributes more to Global Warming than fossil fuels is a lie. This is why some government intervention is needed: The companies aren't responding to new ideas, and they happen to often be fossil fuel companies as well. If you don't create the environment where it lowers fossil fuel consumption, then they win because prices stay high.
Q:kilowatt solar panel help?
Also you can look for INSOLATION TABLES on the Internet. Keep in mind, though, that the useful output of a solar system that produces AC will be somewhat less than the theoretical value. Local conditions, orientation of the modules, dust on modules, wire resistance losses and efficiency of inverters will drag down the true output. My 6 kW system produces just over 4 kW at optimum sun height.
Q:What is a good type of solar panel to get for my house?
The first thing that you have to realize is that solar panels only make DC currant. This is used to charge batteries which when hooked to an inverter will make 20 v. AC. You need a large bank of batteries and a heavy duty inverter to power your house. There is also an automatic switch that will send power back to the utility company when you have excess power available. This is not a small project. Really think this out before you invest a lot of money for nothing.
Q:Homemade Solar Panels?
a solar hot water heater is not a solar panel that makes electricity that runs your hot water heater.....it is merely a long tube or pipe, bent back on itself so there,s, say 00 feet in a 2foot by 4 foot space; it's in a framework and under a sheet of glass or plastic; You put out in the sun and it captures heat.....ever notice how hot the water is coming out a garden hose that has been left out in the sun in summer? Same idea.. we have used them here in the islands for years and they work great. Even up north, a solar hot water heater that preheats the water before it goes to a traditional water heater should work fine.
Q:Cost of a solar panel?
The cost of solar panel depends on per Watt..typically per watt cost is around USD 4-5, so if you take 75W solar panel it will cost around USD 300-375. I hope this helps
Q:What direction do solar panels usually point?
The general answer is toward the equator, so south when the array is north of the Tropic of Cancer, and north when south of the Tropic of Capricorn. In the equatorial zone, one would often still point towards the equator, but other factors such as wanting the panels to efficiently drain rain and dew come into play. But wait, not so fast. Financial considerations dominate in some areas. When afternoon electricity costs more than morning electricity, it may pay to have panels oriented southwest in the northern hemisphere. Where electricity costs the same all day long, it may pay to orient the panels southeast, to harvest more in the morning, when temperatures are cooler, and the panels are more efficient. For solar hot water, SW is usually optimal in the northern hemisphere, because of higher ambient temperatures, and also the usage pattern of most people using the hot water when they get home in the evening. A local installer that has been around for several years will know what orientation is optimal for your area.

Q:Solar panel for your home?
The first thing to understand is that there is nothing complex about a solar panel. It is nothing more than a collection of solar or PV cells on a board that is fitted to the most appropriate part of your home, generally on the roof. There are guides out there that teach you how to build a solar panel and a windmill for just $50, and it’s very easy to make. Best of all, you can save 70% or more on your energy bill, adding up to thousands of dollars each year in savings. I reviewed both free guides and paid guides and have come up with our top to Build your own solar panels.
Q:Why are solar panels made from silicon and not magnesium?
Si is a neutral semiconductor, and, when combined with the other metals in the solar panel, it the panel polarizes, and releases electrons form one end, and accepts them back at the other. Like a water pump. Mg is not the major ingredient because it doesn't have the easily altered semiconductor properties Si does. To put it simply, Si is easier to work with.
