What emerging technologies will make solar energy safer, more usable, more efficient, cleaner, etc?
like cars , house powers
Does it take more time for a solar panel to produce the same amount of energy you would quickly generate with a normal electrical outlet?
A standard electric outlet is 120 Volts and will produce up to 20 AMPS. One average solar panel will produce maybe 100 Watts at peak power (The sun at just the right angle on a very clear day). 100 Watts is like one(1) light bulb of light. The wall outlet will produce maybe enough power for 24 of those same light bulbs, and will do it 24 hours a day. Power (Watts) = Voltage X Amps
If you produce more than enough energy with your solar panels, do you have to sell the excess energy to the utility company or is there a way to store it for later use?
It’s really hard to store the energy locally and recover it at a better price than paying the utility company.
In an area that has a "net metering" plan, the utility company acts just like a huge storage battery in practice.
Let’s say you had some actual batteries in your house, and the solar array generated 1 kWh more than you need during the day. You would charge those batteries, then draw the 1 kWh out at night. Net charge from the utility company: zero. But you would still have to buy the batteries and charger, and deal with the hassle of maintaining the batteries.
With net zero metering, if the array generates 1 kWh excess during the day, you drive your meter backwards, effectively selling to the electric company. At night, when you draw out the 1 kWh, the meter advances again, showing a net advance of zero. Net charge from the utility company: zero. Financially the same, except no batteries.
The example above is just an approximation, though. Some utility companies have various ways of charging you even though your net usage is zero.
I am doing a project on solar panels.
All information given has to be accurate.
May I know how much energy can monocrystalline, polycrystalline, amorphous, vaporware solar panel produce? I also want to know more about solar panels. For example, how did Americans use solar panels during autumn and winter? Is the solar panel used in their everyday life?
Why can’t S’pore use solar panel even though we experience hot weather all year round?
a. chemical energy
b. potential energy
c. solar energy
d. thermal energy
e. more kinetic energy
p.s. if you arn’t going to answer right aka robert down there, then please don’t bother.
Thermal Energy.
Because the temperature of the body increases gradually after running a considerable length of distance.
If yes, why?
Yes- because the panels are converting sunlight to other forms of power.
Anything that difuses that light, obstructs it of filters it will reduce the conversion of energy because there is less energy there. This is true of passive systems, active heat systems and PV arrays.
On a cloudy day I only see a temperature rise in my greenhouse of about 5 degreesF, on a bright sunny day, it can be 70 degrees F inside with the outdoor temps being around 0 degrees F.
I’m doing a science fair project and i need some help. Which is better hydro powerr or solar power. Where I live, there are streams running in the backyard off everyones house. So hydro power is more usful here. What do y’all think?
hydropower is proven and reliable technology and currently the most dominant source of renewable energy in United States while solar power is the fastest growing industry in the country ans also the most abundant renewable energy source.
any way here’s more info:

i: use copper pipes
ii: have a black surface
iii: has a large suface area
1/ Copper is a good heat conductor (which is a reason not to use it!).
But it is:- easy to work with, relatively cheap, and readily available.
2/ Black surface best for absorption of radiant heat.
3/ More area, more heat absorbed.
This is an extra credit i really need please help it would be very helpful!!!!
The simple answer is through electromagnetic interaction. The photon energy of the incoming radiation is transferred in whole or in part to atoms in the atmosphere. As these atoms absorb the energy they begin to move faster, and collide with other particles. Before you know it, there is a large area of faster moving atoms and molecules, raising the temperature of the surrounding area and producing thermal energy.
Is this energy resoure used in Australia? and if so to what extent? (Is it a large-scale energy resoure, or just used on a small scale? Where in Australia is it used – accross most of the country or only in a particluar part
Is this energy resource used across the world and if so, to what extent? Which countries are the main ones using it? Is there a reason why some countries are using it and others arnet?
Thanks
Are you speaking of Solar energy?
Where the sun shines on Solar panels and is used to generate electricity?
People put them on the roof of their house in the UK.
They don’t use it much in Norway because they dont get much sun
Norway is steep and has rivers so they use hydroelectricity there.
I believe it’s used in africa on a small scale, great sun but not much development there
Australia is very sunny and very developed, no wars no terrorists to destroy the solar panals.
Money to buy them in the frfst place.
