Q:Who created the first solar panel?
No solar panel creates energy. The earliest solar panel of any form was probably the parabolic mirror as used, for example, to light the Olympic torch. That goes back to ancient times.
Q:What is the best low power alternative for TV set, to use as screen for dvd player, with a 30watt solar panel?
Do what we do when power is cut (although we have very reliable power - we loose as much as 2 hours a year), is go Amish. That is go without powered technology. Now, for you, you need more than a solar panel (and likely more than 30W, but that is a start) - you need a battery or set of batteries to store the collected power. 20Ah might do. You need an inverter to power things. For that, likely a 300W will do. For a TV, go shopping, and look at the labels on the back of the TVs. I just bought a 24 TV rated at 40W. If you get a 9 LED TV, it may be likely you can run that directly from battery, for many have separate DC brick supplies. With those, you can make a cable to power it directly from a 2V or so battery, if the supply can make 2 to 5V. Depending on your provider, you may be able to get a mini-decoder which uses a separate brick or wall supply, which means the decoder likely can be directly battery powered. Such a decoder may draw less than 20W.
Q:Why do solar panels burn out?
could be temperature, poor design and U-V damage If they are outdoor lamps like mine it is more likely the rechargeable batterys are bad.
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:2- 390 W Solar Panel's Series or Parallel?
Q:A Question about Solar panels?
You are missing one bit of information in order to get an answer. Watts = Volts x Amps Find out how many amps the collector can put out and you can then plug in the numbers into the equation and get your answers.
Q:Could solar panels contribute to global warming?
Claire's argument doesn't make much sense to me either. First; Claire is talking about the second law ('you can only lose or break even'), not the third law ('you can't get to absolute zero'). Easily confused, but not that important! Putting a solar panel down _can_ increase the heat absorbed by Earth. Everything has an 'albedo' (the proportion of incoming light it reflects), and Earth's average albedo is about 0.3 (ie 30% of incoming light is reflected, most of which leaves the atmosphere straight away). By putting a 0.05 albedo solar panel down on a 0.3 albedo surface, you increase the amount of sunlight that is absorbed by Earth and therefore contribute to warming. This heat is re-radiated at the Earth's temperature, in the right wavelength range to be absorbed by greenhouse gases too. If you put a panel down on equatorial ocean, or a black roof, however, there is pretty much no effect (since the albedo change is small). Also, the heating effect only lasts as long as the panel is there. Most panels are estimated to last 50 years, meanwhile CO2 has a mean lifetime of 00+ years. I did some maths and found that the 00 year averaged change in radiative forcing for solar panels was negative compared to the UK electric grid, because the reduction in CO2 emissions has a larger effect than the change in albedo. If I have spare time tomorrow I'll redo the calculations and share them. The albedo change has to be considered though!
Q:what are solar panels?
Solar Panels collect solar energy from the sun and then solar energy is used to produce electricity.
Q:can I connect my pool pump to a solar panel?
I okorder.com/
Q:were can i buy decent solar panels?
Your best bet would be to go down to a place that has magazines and look through their solar magazines, like Solar Today and Home Power. In these you'll will find many places online where you can buy solar and wind power products. They also have good reviews so that you can be an informed consumer and don't end up buying poor quality products. I've seen performance reviews on a variety of models.
