John M asked:
I’m wondering if you total up all the electricity a plant making solar panels uses in a year, the energy the workers take to travel to their jobs each day, the energy used to transport the finished product to consumers and finally the energy used to install them and then compare it to the energy all of these panels will produce during their 20 year life will anything be gained?

Or would be have been ahead to just not bother making the panels in the first place.

ticle that follows, we will explain in how a residential solar (PV) cell converts photons of sunlight into household electrical currents. This process is called the photoelectric effect. We will also explain the physical characteristics of how silicon moves electrons through various states to produce household solar electric power.
Einstein was awarded the Nobel Prize in Physics for his work on the photoelectric effect, not for his work on relativity. Little did one know that the same people who helped us calculate everything under the sun is also the same person helping to bring renewable solar energy to the masses.

The idea of solar energy started over 100 years ago, but the technology hasn’t been as great as it is until today. With companies finding new ways to use renewable energy resources, solar energy is going to be more important. Solar energy is one of the best renewable energy sources because it is so abundant. We’ll never have a sun drought, we’ll never have to wait for the sun to pick up nor will we have to drill into earth like with many of the other renewable energy resources. However, to use solar power, we need solar panels. Solar panels are important because without them the idea of solar energy would be useless.
Solar panels work in two different ways. First there are solar cells that convert light energy into electricity. This is a little on the expensive side, which doesn’t make it as popular as the way energy is used now. However, they are found on a number of products. Space shuttles and satellites use them. Parts of these are covered in solar panels. These objects have the space for all the panels it would need. Another way to use solar panels is by using the heat from the sun. The solar panel attracts the heat and heats up a liquid with a low boiling point. This liquid is transferred to water where steam is used in a generator. This process is simple, cheap and effective.

jim192837 asked:
Solar Panels should face west or south. Facing a solar panel south makes sense since we’re in the Northern Hemisphere. Why west though? Is it because the air in the west is warmer (having been warmed by more daylight) and therefore absorbs less sunlight, letting more energy get to the solar panel???

The more you read and learn about solar power, the more you will understand just how much does solar power cost. Solar power is a free natural source of energy from up above, it’s a gift of God, we call it the sun and it is for everyone to use. When solar energy hits the earth it brings us heat, warmth and a sense of well being, it spreads over the earth’s surface evenly. Just like we capture the sun’s rays into our car in the summer when the windows are closed, and we open the windows to let the heat out, solar panels are doing a similar job capturing the rays of the sun and converting it into electrical charges useable to heat our homes, power our appliances, heat your water, run your air conditioner, TV, DVD and a lot more. Unlike gas or oil heaters that you continue to pay monthly in order to have power or gas heat in your home. Solar power does provide heating, cooling and ventilation, free of charges. How much does solar power cost in a long run, nothing and you may not know this but the electrical companies will pay you money for having your meter run on the opposite direction.
Greenhouses operate with the same principle having glass or clear plastic all around it attracting and capturing the sun and not allow it to escape causing the greenhouse to stay very warm for the plants to grow effectively.

I am planing to put solar panels to help lift some strain off the alternator and thus helping gas milage.

I know solar panel’s contribution would be a fraction to what alternator does but it might show in the long run. also it will keep the battery charged longer.

John C asked:
How much is the integrity of a concrete tile roof compromised with installing solar panels? I understand they must be anchored, with some difficulty, to the roof frame below the tiles.

to put the solar panels on top of the roof have to wait. We are concerned that they might get hurt. We did get are permit.
