- Q:Solar Panels not working very well, they have faded. Is there any paint or anything else I can do to restore them? Thanks Eileen
- Unfortunately Eileen the panels are bound to fade as its par for the course. Over time much like everything else (from an AC condenser to your knees and hips) everything starts to go south. When did you purchase and install your panels? If this was done within the past few years then something is definitely wrong, and you should have the manufacturer and installer come back and replace the panels....on their dime of course. Is the warranty on your panels still in effect? If so then its definitely something that they have to come back and take care of. There is a company I know of called Sun Electronics that has a 20 year warranty on their products, so if its worth anything you might want to buy your new panels/system from them. The panels around today are more efficient than those of years past, and with the cost coming down due to economies of scale and the tax incentives you might want to consider getting a new system. Sorry to let you down though Eileen!
- Q:all i want to do is provide enough electricity for 2 fluorescent bulbs i was looking at some 80 watt panels how many of those would i need and what else do i need for storing the electricity for use at nite? and how much would it all cost?
- The solar panels are made in China because there are fewer environmental regulations and cheap coal power. It takes a lot of energy to melt silicon and there are toxic waste products. It would be three to five times more expensive to make the panels in the US ( three times is just for reprocessing the toxic wastes ). Solar cell made in China are about $2 a watt, perhaps as low as $ a watt but in truth the claims for $ a watt or less solar panels as in thin film solar panels have much lower efficiency and require perhaps ten times more surface area.
- Q:I'm thinking of getting a solar panel for my house to help cut back on power use (I live in New Mexico). What sort of appliances can I run on a watt solar panel? Is it worth it to get a single watt panel or is it more efficient to get a multi-watt panel?
- watt is a very small amount of electricity. The typical household uses several million watt hours per year. watt would be enough to trickle charge a battery to run an LED nightlight. I believe the little self contained walk lights that I have put out have a 0.35 watt Ni-Cad battery. That could be recharged by a watt solar panel.
- Q:Hello, I have been trying to go green, I Have purchase somesolar panel they are about 45watts I been putting it against my window and getting ok power out of it enough for my lights and a couple of low watts gadget (cellphone, 2v light, portable dvd) for couple of hours.But its seem to drain the 2v faster then I can charge Am I getting the most power out of my panel?Or should I place it on the roof? I'm in Texas and it gets hot and sunny the sun beam my room windows pretty good during 4pm-6pm.
- Solar panel generates fairly low, unreliable source of energy. They are most likely very expensive. Despite all of that, your window may act as a beam filter by refracting the beam or reflects them off trough total internal reflection causing a low yield of sunlight harvest. Sunlight is also necessary to hit the panel 90 degrees to harvest maximum output.
- Q:How can I calculate the amount of watts needed for a solar panel to power a water and air pump in gal/hr and a 600 watt LED light?
- Mimi: Solar Power is not really that economical, and has many other disadvantages as well. You did not specify much info in your question as to the size of the water or air pump. So let's make some assumptions to get you some numbers. ) Let's say the water and air pump are about HorsePower (HP). The HP pump , considering efficiency losses, will draw around ,000 Watts , or kW. 2) The 600 Watt LED Light is quite high --- they are usually much smaller lights 40 Watts or less. BTW --- these LED lights are very expensive light as well. Just so you are aware. Between the pump(s) ( maybe 000 to 400 Watts) and the 600 Watt light ----- and without knowing the specifics --- you are probably looking at around 2,000 Watts or 2 kW. A 2 kW Solar PV unit will run around $20,000. The PV unit will only run at full capacity during daylight hours. They usually average about 5 hours per day. So you will only be able to run your pump and LED Lights during the middle of the day --- maybe 0:00 AM to 5:00 PM. If you want to run the pump and lights after sundown, you will need battery back-up. The electric storage batteries will likely run about an extra $5,000. They will last about 5 years. If you decide this doesn't work out well --- you can stay with the local utility --- at $0.0 per kWh. It will cost you about $0.0 per hour to run the pump --- maybe 30 to 50 cents per day. It would cost you about 6 cents per hour to run your light. Maybe 30 or 40 cents per day. You could essentially run your pumps and light several hours each day --- all for about $ per day, or $365 per year. This sounds like a less costly alternative.
- Q:I riped two solar panels out of some solar light and tested them. I found out that they both produce 2 volts(I have no idea on the watts or amps). Iquot;ve hooked them up to an electric motor that can be driven by a AA battery, but when I hook the solar panels up to them nothing happens. What is wrong?
- Mark G has a good answer. If you leave your voltmeter on the solar cells when you hook up the motor, you will see the voltage drop to near zero. Same thing would happen if you tried to use 2 9 volt batteries to start your car. They just cant maintain the voltage when high curent demands are made.
- Q:How Is heat From the Sun Transferred into Currents From solar Panels? (Explain Deeply Please)
- Build okorder /
- Q:I am planning to run a couple of dc motors on solar current. I have a couple of 450mA 4V, 200mA .5V, 00mA 9V solar panels with me. I need to run a pair of .5A 9V motors. Suggest me a circuit along with other equipments I might require. For your info, I am trying to build a solar powered drone / UAV
- I don't think it is enough solar power. Your motor requires .5A x 9V = 3.5 watts. The solar cells are .450A x 4V x 2ea. = 3.6 watts, .2A x .5V = .3 watts, .A x 9V = .9 watts total solar = 4.8 watts. The problem with connecting the cells in series to get the right voltage, like the two 4V cells in series with the .5 volt cell (total 9.5 volts) is that the .5 volt cell limits the maximum current to only 0.2A. If you paralleled that with the 9V cell, you would get 9 volts at 0.2 + 0. = 0.3A, too low to operate the motor at its design current and voltage. The best you could do is put the two 4V cells in series, and in parallel with the 9V cell (a blocking diode might be a good idea, but probably not required for such a small array). That way you get 8 volts at 0.55 amps.
- Q:There are so many solar panels and kits it is very confusing. I need to know what exactly I would need if I had an underground home with no electricity. I want to be totally off the grid with solar power. Someone please explain to me in simple terms what exactly I need. Maybe give me a link to the right kit for me. Also are they easy to install? Are there instructions that I need to download?Thank you
