Today you can even buy an air conditioner that is powered by solar cells during sunny days and at night you can run it from the backup batteries, which are recharged the next day.
The development of solar technology has now discovered ways to use the infrared rays of the sun's energy, so that now it doesn't even have to be a sunny day to activate the solar power for homes. With a little more development we will son be able to use over 30% more power from the infrared rays, which is a tremendous boost from the 6% that we now use.
Another use of solar power is to heat water.
Solar cells are made of two layers (a positive side and a negative side), when they are placed on top of each other they create an electric field, the same way a magnet does.
Solar air heating panels are another system that saves energy, and is suitable for homes that can't use passive solar heating.

Solar energy is first of all a very useful source of alternative energy, as it can provide electricity during power failures.
How hard is it to maintain solar panels? The good news is that they require literally no maintenance at all. Solar panels can last for up to forty years and beyond in some cases.
Solar panels need to be pointed towards the most direct source of sunlight in order to absorb the highest possible amount of solar energy.
Although at present solar power is more expensive that electricity the promise of concentrator technology is set to change this.
