Q: If i took a lazier pointer and aimed it a solar panel would it take in the light. Also what types of lights would work on a solar panel like L.E.D, uv light bulbs.: If you mean a LASER pointer, then the answer is YES. However, the light is concentrated on a very tiny spot, so the panel will NOT generate much. Laser pointers are rated in milliwatts. A typical red laser pointer is rated at maybe 3 milliwatts. So, that is all that will be transferred at MOST. You don't get something for nothing, so the panel MAY put out 3 milliwatts from the laser pointer, but probably less since the solar panel is not 00% efficient. Solar electrical panels rely on sunlight over a large area measured in terms of many square FEET of area. As for driving lamps, the lamps do not care where the power comes from, only that the voltage and current are correct. Most bulbs will work equally well on AC or DC. Solar panels are used to charge batteries, and the batteries are used with an inverter to supply 0 VAC to things like appliances. What you CAN do is use a laser pointer to turn off a photoelectrically controlled light, such as a streetlight, maybe. Many streetlights have a photocell on top which looks at the sky and turns on the light when it is near dark until shortly after dawn. If you can shine a laser on the dome of the photocell, it MAY be bright enough to fool the photocell into thinking it is daylight and turn the streetlight off for a while...

Q: How many solar panels would it take to run an electric motor the needs 480 volts and pulls about 45 to 50 amps?: Quite a bit to run 480 volts @ 50 amps. Ohms law will give you the basic level your looking for but also you need to consider power storage ... Conversions .... Start up power vs running power levels ... it can be done but this is a bigger system then what I need so I cant just give you an number your panels will be rated in wattage and amperage you then take that power and put it in storage (battery) to inverter system (mine is 20 volt) you will need to have a 480 inverter for your power level. good luck hope I was of some help.

Q: Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?: If you're really planning on solar energy, don't waste it on your own consumption. The Hydro company pays you for the energy you put back into the grid....the strange thing is, you buy the power back for less than you sold it, so you actually profit on the power you make! look into this. I wired a nice house for a doctor, and although I didnt supply the solar system, I learned of this concept there. The guy who installed her system charged her around $40,000.00 and the system would never be able to run any large portion of their home. They, of course sold the energy to the utility.

Q: Can solar panels be installed on a parking lot or carport?: Yes, solar panels can be installed on a parking lot or carport. In fact, these locations are ideal for solar panel installations as they provide ample space and can generate clean energy while also providing shade and protection for vehicles. This dual-purpose approach helps maximize the benefits of solar energy and optimizes land usage.

Q: Can solar panels be installed on airports?: Yes, solar panels can be installed on airports. In fact, many airports around the world have already adopted solar energy systems to power their operations and reduce their carbon footprint. Solar panels can be installed on the roofs of airport buildings, canopies in parking lots, or even on open land surrounding the airport. They provide a sustainable source of clean energy and contribute to the overall sustainability efforts of the aviation industry.

Q: Do solar panels require direct sunlight to generate electricity?: Yes, solar panels do require direct sunlight to generate electricity. While they can still produce some electricity in indirect or diffused sunlight, their efficiency significantly decreases without direct sunlight. Direct sunlight provides the optimal conditions for solar panels to convert sunlight into electricity effectively.

Q: Ok so I am planning on buying a solar panel. I am doing it to possibly sell the energy that it stores. It is a 20 watt panel so I am just wondering if every week or month if I sold that energy that it stored would make me a good profit. I am not hoping for thousands of dollars a month..just like 00? The solar panel cost me $,00 so if so, how long do you think it would take to make good profit. Also, how much would I make every week or month?: I will give you the tools to answer your own question. Here is the solar resource map: rredc.nrel /solar/old_data/nsr... Use it to look up the hours of peak equivalent sunlight per day in your area. For example, let's say it's 5 hours / day. Then per year you get 365 x 5 = 825 hours of sun Your panel is 20 watts, or 0.2 kW So the energy produced per year is 825 x .2 = 383 kWh You'll have to use the proper numbers for your own area, of course. Anyway, you can take that 383 kWh and determine how much it would cost at local electric rates. Never know, on some islands, it's $.00 per kWh. Check with your local electric company for rates.

Q: how much power is generated with solar panels? also please give me links for that information.and how much would the costs be for this alternative energy source?: The amount of electrical energy (kWh) a kW grid connected solar PV system will generate on an average day (kWh/kWp.day). There are some factors that will determine just how much electricity you can create with solar panels for your property - The size of the system, the direction that your roof faces and the angle of the roof comes next. For optimum performance, your panels will need to be on a 35-degree angle, facing south.

Q: Installing solar panels requires a big initial investment. Before I make this investment I want to check to see if the money I will save by installing solar panels will actually pay for this investment, in the long run. To calculate my savings, we should consider the area (square feet) I currently have available to install solar panels. Look at the available sunlight and its intensity in my state each month of the year. Based on this data estimate how much energy my solar panel will generate. Then compare that with how much energy (kWh) I currently consume based on my electricity bill.: SIMPLE, EASY WAY TO KNOW EXACTLY HOW MUCH IT WILL COST. Everyone has great answers, but here is a website that will do all the thinking for you. Go to: mercator.nrel /imby All you have to do is to locate your property on the map, draw the outline of the solar array, and then click Run. It will estimate: - Cost - Available Rebates - Tax Credits - Estimated payback This program is operated by the National Renewable Energy Laboratory. Good luck!

Q: wondering if i should get them?? not sure if its worth leasing? also anyone know anything about solar city?: They are absolutely worth it. I had a town house in Boston with solar panel shingles and they were able to supply enough energy for me to feed back the grid-- literally making money off of them. I am building a very large home in the suburbs now and we are doing solar shingles on that. Our contractor estimated that with our geotherm heat pump and energy efficient lighting we should still be able to throw back more energy to the grid all year round! As for leasing it is not worth it. For one thing, most leasing contracts prevent you from selling your energy to the grid yourself but rather they take a cut. But a bigger issue: the government gives you a tax credit on solar panel installations but only if you purchase them! I did the math myself the first time I did solar panels and with the tax credit I saved 25% over leasing. Something else to consider is that with your own panels you can connect a variety of other systems to your home and modify them as needed.
