Renewable Energy Monitoring Systems – The Next Big Thing?

If micro-inverters are the current craze in the solar industry, then I predict that solar energy monitoring systems will be the next big thing.

Micro-inverters (and other parallel technology) are given lots of attention because they can increase the efficiency of a system by up to as much as 10%-20%. Similarly, solar electricity systems that are hooked up to monitoring systems have a 10% energy production increase over systems that are not hooked up to monitoring systems, according to Will Shortt, CEO of Deck

written by David Belden

How can companies like SunRun, Sungevity, and SolarCity provide a zero down or $1000 down solar lease while charging less per month than a utility company? Sound too good to be true? It’s not. Here’s a high level overview of how solar leases (and PPAs) work.

First, let’s briefly review how a homeowner would purchase and install a solar system without the benefit of a solar lease or PPA. A home owner purchases
