Design PV systems quickly and conveniently

Sunny Design

With Sunny Design software, you can plan tailor-made PV systems for your customers. It could be a grid-connected PV system with or without a battery-storage system, smart energy management or e-mobility, an off-grid island or hybrid system - Sunny Design takes all technical specifications for the various components into account and provides you with relevant data for a cost-effective assessment of the system. That means that you can match your PV systems to suit the circumstances on-site.

It couldn't be easier. Simply open Sunny Design in your web browser or on your iPad or Android tablet and enter the necessary data in the user-friendly interface. In just a few minutes, Sunny Design will configure the ideal PV system for your customers on your behalf.

You can use Sunny Design free of charge.

Comprehensive energy system planning and simulation

Sunny Design pro

In addition to the PV system, Sunny Design PRO takes battery-storage systems and thermal components, such as combined heat and power plants and heat pumps, into account in system planning. That means that you can plan and simulate comprehensive sector-linked energy systems. Using customized purchase and feed-in tariffs as well as detailed project and capital costing, you can create reliable efficiency forecasts for the entire system. The extensive project documentation helps with field sales meetings and simplifies subsequent energy system implementation.

It's easy: you can give Sunny Design PRO a try with a month-long free trial. Enter your data to receive a comprehensive and professional visualization of the energy system in no time at all.

You can read more about what Sunny Design PRO has to offer in "Cross-Sector Energy System Planning".
