How solar panel cost and efficiency have changed over time

solar panel cost and efficiency over time

Solar panel technology has been around in some form for a long time – Bell Labs invented the first useful solar cell more than 60 years ago, and scientists have known for centuries that the sun can be used to produce energy. However, it’s only in the last ten years or so that solar photovoltaics (PV) has really taken off as a renewable energy source. There are two major factors influencing the technology’s growth: the steady improvement of both solar panel cost and solar panel efficiency over time.  Continue reading

Solar energy vs. fossil fuels: how do they compare?

fossil fuels vs solar energy graphic

If you’ve been following the ongoing battle between solar energy vs. fossil fuels, it might seem like the predominant resources on which the global economy depends – oil, coal and natural gas – will be completely phased out of existence in 2017. In reality, these resources still power most of the planet,  while renewable resources like solar and wind only contribute some two to three percent of global energy capacity. This reality check begs the following question: how does solar really stack up against fossil fuels, and why is there so much excitement about the growth of solar?

What is Net Metering? SRECs comparison

what is an srec graphic People often think SRECs and net-metering are the same thing, but really, the comparison is like apples to oranges. It’s true that they are both important to getting the best financial results from your solar PV system, but SRECs and net-metering actually have very different, distinct functions.

Both can have positive financial effects and understanding the difference between the two can help you, as the owner of a solar PV system, to maximize the benefits of both. Here’s how it all works: Continue reading
