Solar Energy – The Basics Part 1

Solar Roofs initial cost is about twice as much as many standard roofing systems. However many of us know little about them in general.

Like how does a solar roof system function? This can be complicated to explain to someone that is not familiar with solar systems. Basically when sunlight hits the PV panel, it’s cells absorb that energy and generate electricity in the process. The electrical properties of the PV cell provide all the voltage needed to drive that current though an external load. The system generates DC electricity, which is converted  to  usable AC power. The power will be stored and  distributed through the existing electrical outlets throughout the building. Of course that is just the short version, but hopefully you get the point.

Is a solar roof system worth the investment? Well that depends. If you are in Florida and get plenty of sunshine year around you will get more out of a system than somewhere like Alaska. It’s not uncommon for companies to save 40% or more on their electricity bills a year, and most save a minimum of 15%.  Many state and federal incentives are offered as well, that can save a company even more money. As you can see these systems can eventually pay for themselves, and a good system should last 20 years or more if properly designed and installed.
