Let’s go over the whys of string sizing. What is it and why do we do it?
String Sizing Basics
String sizing is critical when you’re putting modules in series. Remember that when you put modules in series, the voltage goes up. It’s additive.
Another thing that makes the voltage go up is cold temperatures. That means in […]

The Fronius Solar.creator is a free and easy-to-use online configuration tool that supports you when designing PV systems with Fronius inverters. It is connected to a […]
Like much of the equipment in the solar industry, technology found in string inverters has evolved over the past 10 years. Even just a few years ago, designers would be wary using string inverters on sites with challenging roof architecture or slight shading. With modern string inverters, those concerns are rarely issues for a solar […]
What tools do solar designers use to improve the speed and accuracy of their project designs? This new, free solar design course from Unirac gives you a quick introduction to many of the top solar design tools available.
I’ve always been surprised by the number of different approaches to solar design. Especially residential solar. When you’re […]
With demand increasing for energy storage, more solar customers have questions about how batteries can work with their solar systems. Let’s talk about how to couple PV and batteries as well as the various types of inverters on the market.
There are essentially 2 different ways an inverter can output power:
Interactive, aka grid-tied, aka current mode, […]
