Whether a pointed gable, tented roof, modern city villa, single-family home or apartment building, it also pays to install PV modules on the north-facing side of buildings. This delivers more energy yields and makes system operators independent of rising electricity prices. With the Sunny Design planning software, you can display up to six module arrays during system planning, allowing you to incorporate more roof surfaces into the design from the outset. We will show you how to do this (including with a carport) for north-facing installations as well, because diffuse light can also result in a good yield. The software allows you to easily design complex systems in a single step.

The Sunny Design planning software has been used to plan millions of PV systems worldwide since 2007. The new release coming out in late April lets you precisely model where shading might be on the modules and shows you where direct irradiation is lost.

Have you ever heard about polystrings? Did you know that PV plants with this special plant design benefit from more energy yield over the course of the day? Sunny Design Web will help you easily design a polystring PV Array. Find out all you need to know about this key but often overlooked feature.

It’s not always obvious how to choose the size of the battery (kWh) or the rating of the battery inverter (kW). These choices, along with your specific household energy usage, have a large influence on the cost and benefit of a new battery storage system. In this blog, we will show you examples from SunnyDesignWeb.com that illustrate the effect of different battery and inverter combinations for a typical household.
