The topic of renewable energy is often highly politicized and controversial but there are many conflicting accounts of how solar energy works. There are however some untenable facts about the processes and efficiency of solar energy and long term cost benefits to households which cannot be contested.

Solar energy comes from the sun, which can, if harnessed properly, provide the entire world with a source of energy which is virtually inexhaustible. This carries with it many great advantages. One, solar energy will not be subject to the ups and downs of an energy market. The supply and demand curves that traditionally regulate the price and the reach of energy would not apply.

Another fact that is not arguable about solar energy is that it is a clean alternative energy source. Also, it would help greatly the issues of global warming and public health, because it does not give all the pollutants that other fossil fuels have been known to release. In fact, it is this solar energy which we actually harness when we mine for coal and oil, because those fossil fuels are produced by solar energy which has been compressed underground for an incredibly long time (millions of years). Nonetheless, all of the energy that is stored in fossil fuels today could be replaced by just 20 days of sunshine.

How solar energy works in solar panels

Solar panels typically comprise of semi conducting materials such as silicon which absorb the photon light energy from the sun. This absorption leads to electron getting knocked loose form their respective atoms and allowing them to flow through the panels producing electricity. An array of solar panels can typically produce enough direct current (DC) electricity to power a household

Uses of solar energy and how solar energy works in households

Some the typical uses of solar energy today include lighting and heating of buildings both through natural unharnessed solar power (called passive solar energy) and through the use of solar panels. Solar panels or collectors which harness solar energy are able to utilize it in even more ways. Solar panels can be directed to uses such as water heating, radiator generation, air-conditioning and many other uses. As a matter of fact, people have been discovering how solar energy works for some time, as solar energy has been used for air conditioning purposes since the 1980s.

Cost savings for households using solar energy

Aside from providing an alternative to fossil fuels, which are increasing in price by the week, solar energy also brings with it other cost savings. As a whole, people who use solar energy instead of fossil fuels can save up to 40% on their heat and air-conditioning bills, up to 70% on their gas bills, and up to 60% on their power and electric bills in total. Overall, households using solar energy can expect to pay about half of what a more traditional household would pay using fossil fuels. If not for the environmental concerns, many people are choosing to find out how solar energy works simply for these economic advantages.
