How difficult is it to install a solar panel kit?
A solar panel kit is not incredibly difficult to install depending on how handy someone is. One can purchase solar panel kit at Home Depot that will come with all the instructions one would need.
How many 290 lumen 7 watt light bulb is needed to power a 5 watt 12 volt solar panel?
None, since one does not normally "power" a solar panel. However a single 7w lamp would be useable with a 5watt panel but with reduced efficiency unless the panel was used to charge a battery first and then the bulb was powered by the battery.
Can solar cells used in mobile phones?
No, cell phones draw too much power to be supplied by solar cells, unless you used a large solar panel. But you certainly can't build a solar cell into the back of the phone like you would a solar calculator. For example, one web source says a cell phone draws about 1 W. Another web source says solar panels can put out about 1.2 W for 100 cm2 in bright sunlight. So to power the cell phone you'd need a solar panel at least as large as a CD, probably more like a sheet of paper.
How many watts are required to start a 7 HP 12 VDC motor you want to start the motor on solar panel?
For calculation purposes 1 HP is equal to 746 watts. So you have a total of 746 x 7 = 5222 watts. The amperage will be A = W/V = 7222/12 = 435 amps. You can not start the motor directly off of the solar panel. You would need a large 12 VDC parallel connected battery bank to obtain the amperage capacity to start the motor. The solar panels would be connected to the battery bank and used to charge the batteries after the start.
Why are solar panels not widely used?
My guess is that integrating solar panels into pre-existing energy networks would be difficult and costly. You also have to wonder how many solar panels we would need to replace the electricity we use. I imagine it would take very many solar panels just to keep a corporate building in power. I assume there would also be much protest towards solar panels coming from the electric companies. If we all switched to solar, the electric companies would either go out of of business or be forced to convert.
What is the energy transformation of an electric gate with a solar panel?
Well, it would be solar to electric. Right? Because if the way to operate a gate has a solar panel, but the gate is electric, it would be solar to electric.
Can a solar panel cook a french fry?
It would depend on what the solar panel did. If the french fry just laid there on the solar panel than it would come out as a cooked potato but if the solar panel was hooked up to a fryer, it would be able to cook the french fry. Remember, solar panels can power houses so I think it can cook a french fry!!!
Why are the solar panels usually painted black?
If they are PV panels or heat pipe panels, they are not painted at all, paint would stop them working. Only a simple hot water radiator panel would be painted black and you would do this because the colour black absorbs all solar radiation, other colours reflect some of the suns energy.
Where would you find a solar panel?
on a house
What is a device that converts solar energy into electricity?
a device called a photovoltalic panal
Why was the first solar panel car in invented?
the first solar panel car was invented so that gas would not be needed therefore there would be less polution
What kind of batteries are used in a solar panel laptop?
A solar panel laptop would use a battery which would be charged by a solar panel. There are several brands available through a company named "Tree Hugger," there are also a number of other brands available.
Can solar energy heat objects?
If you use a solar panel which you would hook up to a heater the answer would be yes
Would a solar panel work in overcast skys?
Yes. A solar panel would still produce energy in overcast skies, but at a lesser amount than in sunny skies.
How much energy can solar panel conserve?
Depends on the type of solar panel. You would need to look at the manufacturer's data to know the exact amounts.
How much solar panel need to charge 12v 180 ah battery?
To answer this question the output current and voltage of the solar panel would be needed.
What part of school would relate chloroplasts?
