2013 - 2014

In 2014 we built the first off-grid SMART office where our showroom “Center for Energy Solutions” is currently located. In the same year 3K AD launched a successful cooperation with Greenpeace Bulgaria which continues to this day. Some of our emblematic joint projects are: “Exhibition of RES, Sea Station – Varna”; Sea sunflowers project – beach umbrellas equipped with solar chargers, as well as the construction of a fully autonomous system (off-grid) for hot water through solar panels at the “Taja” rest house in Stara Planina.

2015 - 2017

In the spring of 2015 we introduced the second-generation ThermoSol controller, K2 series, for water heating through solar panels and in 2016 after the production of its first two series we installed dozens of systems across the country. In 2017 we started developing a third version of the controller that we will introduce in the spring of 2019.

2017 - today
