Efficiencey of a solar energy,system involve in solar energy & the cost involve in solar energy?

We Answered:

The sun gives 1000 watts per meter square. 15% of this energy can be utilized by solar panels.

John Said:

Are you sure about the solar energy system?

We Answered:

Wait, what?

As in, does solar power work?

Yeah, solar power works.

Alexander Said:

Could the suns energy be used to move our solar system near a younger solar system over about 4 billion years?

We Answered:

To move the entire solar system one would need to move the Sun and every planet and even every last one of the countless objects orbiting the Sun otherwise so many objects will get their orbits messed up that all life in the solar system would be at risk of getting annihilated by collisions.

There is simply no reason to even attempt moving the entire solar system, or even a single planet for that matter. It takes a lot of energy to move heavy objects. Planets may have a lot of resources to take advantage of and live off of for a long trip but most of it will be dead weight. A better option would be to simply move a large resource rich asteroid with a colony built within it. It would be much easier to accelerate, it could contain plenty of metal, water, and fuel (in the form of helium 3 and deuterium for fusion most likely) and on top of that its thick exterior would protect the colonists within from radiation and interstellar matter the "ship" would collide with during the journey.

The Europeans didn't sail the entire continent to the Americas, they just sent ships. When you go to the grocery store you don't move your entire house. There is absolutely no reason to move the entire solar system.

IM triyng to installa system with solar Energy. HOw do i choose the inverter and controller ?

We Answered:

you need to buy one that can handle what your panels can produce at max output plus a little.
say you want 26kw but your panels can produce 35kw on a good sunny day. If you buy a 30kw inverter, there is a good chance you will fry it.
My advice is read up on your panels and find out what the max they can produce is and then start looking. Even though you will have some loss in the transfer and conversion from ac to dc, it is still better to buy more than you need. That way you can upgrade at a future date if you decide you want more and dont run the risk of having power trip failures or even worse destroying your entire system.
There is alot of information available on this topic on the internet if you search for how to choose and inverter. Some will give you a formula, say 110% of desired output, others will say this is not needed. Read about how to choose one to fit your demand then go looking for one that has the price and features you need.

Phyllis Said:

How does the law of confederation of energy applies to solar system?

We Answered:

Do you mean Law of Conservation of Energy?
In that case, all it means is: Energy can't be created nor destroyed. It is always given off in one form or another.
