To begin with solar panels are sheets made of PV (photo-voltaic) cells arranged in modules that convert the light energy that fall on them into electricity. This mechanism works on the photo-voltaic effect, which was discovered by Albert Einstein. Interestingly he was awarded the Nobel for his papers on this rather than the famous relativity theory. solar installations commercial are designed for domestic use to power houses individually; they are almost all the time placed on the rooftops.
Why solar panels? Why residential ones?
It is quite apparent that the clean energy drive in the world is moving toward micro-level execution encouraging a bottom up approach. This is mainly because of the expensive nature of the infrastructure required for large scale or industrial implementation. Electricity being the basic amenity it is; the governments of the world cannot afford to bring a hike in its price. Thus there is a lot of encouragement provided by governments all over the world to employee residential solar panel system in the form of subsidies and levies, keeping up with the trend of sustainability. The most important feature that ties together everything is that, solar power is the only clean source of energy that can be implemented at a domestic level.
It is noticeable that many people cannot get the formula to work out financially given their monetary status and due to the several variables they need to satisfy. However, those who make the installment, have to spend a lot for the initial investment that is definitely realized over time.
