Did you know that in 15 minutes the sun radiates as much energy as mankind consumes in all forms, during an entire year? Did you know that in one day the sun radiates enough energy on the United States to power the entire nation for a year and a half? Not only that, but it does it every day – for free. Solar power is a safe, clean and renewable energy resource that will no doubt play a vital role in powering our future.

How can the energy from the sun be harnessed? And how can we put that energy to practical use? Harnessing the sun’s power is accomplished through the use of a photovoltaic system. Basically, the word “photovoltaic” is used to describe a device, which when exposed to the sun’s radiation, creates electrical power. It’s abbreviated as “PV”.  PV systems incorporate the use of PV modules, (which are also commonly referred to as “solar panels”), to generate energy from sunlight and inverters which convert that power and safely deliver it to the utility grid for our use.

When properly designed, a PV system not only helps our environment, but it makes economical sense as well. Owners of PV systems make an important contribution to protecting our environment while enjoying the economic advantages of their “clean” electricity at the same time.

In the following sections you will learn more about how to plan your own PV system and why the inverter is such an important component.

Come along...for the sun is the future!
