Q:The future of solar panels?
Well I think solar technology is a viable solution to our energy problem. The only issue is that right now it takes too long for the panels to pay off unless you have a fairly big facility to power. Solar panels are getting cheaper and cheaper though, soon they will pay themselves off in less than ten years and I think then you will see more people buy them which will bring the price down even more. Solar done on a large scale is something that needs to be invested in ASAP. They can create jobs, power our nation and slow down global climate change.
Q:Solar Panel/Energy help?
The rating of a solar panel is a maximum continuous rating. A 200 Watt panel will give a maximum of 200 watts under ideal conditions. A computer and monitor use about 400 Watts. not per hour - watts is Volts * Amps and a measure of Power. In hour a computer and monitor uses 400 Watt hours (Wh). Wh is a measure of Energy. To power a lab of 0 computers you will need 0* 400 = 4000 Watts. To run this from solar panels through the day only you would need a 4000 Watt panel. Except - its cloudy, the sun is in the wrong place - many factors reduce the output. To be reasonably safe you would need about a 2000 Watt panel. Then you would need batteries to store power through dull periods AND a voltage converter to change from low voltage DC from the solar panels to the mains voltage for your computers.
Q:Solar Panel watts needed?
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:know about solar panels?
Solar panels, often connected to other panels to form an array will produce electricity when exposed to the sun. At this time solar panel is one of the fastest growing business in the world. Given the fact that most of our energy comes from fossil fuels (Oil, Natural Gas and Coal) and that those resources are getting used up and more expensive to get to, and given the fact that solar panels are getting cheaper and more efficient, eventually, the electricity produced by solar panels (or photovoltaic panels as they are sometime called, PV for short) will be cheaper than that of CO2 spewing electrical plants. Actually, it could be argued that if the coal, natural gas and oil industry was not subsidized so much by our governments, and if you demanded that the process of producing electricity from those sourced be as clean as PV, PV would be a cheaper source of electricity than fossil fuel already. Make sure to also look into the solar panels that produce hot water. SHW (Solar Hot Water) is very developed in country such as Israel, where the law demands that all new house be build with SHW systems. Those panels are very efficient at capturing the heat of the sun and produce hot water much cheaper over their life than using gas or electricity.
Q:What size and watt solar panel?
I think that typical solar panels are 2'x4' and produce something like 800-000 wh per day. (That's 0.8 - kwh per day.) More in the summer, less in the winter, if they're aimed sort of at the sun. There are newer, more expensive panels that produce more. There are also thin film panels that are less expensive, and probably more sturdy. You then have a couple choices. In a house, you'd have an expensive inverter to connect to the utility power, so you can have power at night when your panels aren't generating anything. In a trailer, you want 2-4-6 deep cycle car batteries to store the power. Then you could have an inverter to convert that power to 20v AC, so you could use normal appliances. Or, you could buy appliances that run on 2 volts DC. Maybe a combination of both. You'll need to figure out how much power you're going to use, so you know how many panels and batteries you're going to need. The calculation is easy. Figuring out how much power you need is hard. You need deep cycle batteries because you can repeatedly charge them way up and run them way down. Ordinary batteries die fairly quickly when you do that.
Q:How Do Solar Panels Work?
sunlight is collected by cells in a panel which is transefered to enrygy
Q:solar panels, help?
380 W/m2. An Earth-orbiting satellite has a solar panel that measures .35 m by 4.86 m, which converts solar energy to electrical energy with an efficiency of 26%. In one hour, how much electrical energy does the panel produce? 380 W/m² x .35 m x 4.86 m x 0.26 = 2354 watts energy is watts*time E = 2354 watts x 3600 sec = 847472 Joules or, E = 2354 watt-hours
Q:How to select solar panel for this application?
Be aware that you cannot discharge the full capacity of a lead-acid battery without destroying the battery. With a normal battery of this type, you would only want to discharge about 20%, so you would need a 70 AH battery bank. For the 3-day requirement, 500 AH. This is still within reason. If you didn't have the 3-day requirement, you might consider going with NiMH batteries. Back to the 500 AH bank, you would usually charge at at least 5% C, or 25 amps. At the 5 volts that you need for charging, this is 375 watts. Possibly you could go as low as 200 watts.
Q:hi i am asking about the life of solar panels?
They degrade over time, losing efficiency. They're generally good for several decades.
Q:Solar panels for a netbook?
That strikes me as completely impractical for most circumstances. The power output of your mains adapter is 30W and to do that you are looking at at least five or six square feet of solar panels costing in the region of $600 even from a surplus supplier I know. You could do it cheaper (maybe $50 on panels) but then you would be looking a more primitive panels and need perhaps thirty square feet of solar panels. This is a completely different exercise to creating a solar powered USB charger - the power requirement is a lot higher. Astronomy and space?
