Klarsolar

Company Overview

Klarsolar GmbH

Heidelberg, Germany

2018

Approximately 150 employees and a revenue of 50.4 million USD in 2023 (source: zoominfo.com).

What They Do

Klarsolar GmbH is an innovative provider in the photovoltaic sector, specializing in the digital planning, sales, and installation of PV systems, energy storage, and wall boxes for private households. The company aims to make the use of solar energy simpler and more cost-effective for its customers, which is reflected in their motto: "Photovoltaics must become even easier and cheaper for our customers." Klarsolar offers comprehensive services, including a digital configuration within three minutes for cost estimates and profitability calculations, manufacturer-independent planning, and nationwide installation by local teams (source: klarsolar.de). The target markets are exclusively private households in Germany seeking 100% green electricity production and solutions for optimizing self-consumption.

Projects & Track Record

By the end of 2023, Klarsolar has successfully implemented over 400 PV projects for private customers, focusing on smaller residential installations with integrated storage and wall boxes. A notable project is the introduction of the Klarsolar HERO HEMS, developed in collaboration with gridX, aimed at equipping several thousand households by September 2024. This system optimizes the self-consumption of PV electricity, battery storage, EV charging stations, and heat pumps through a hybrid cloud/IoT technology that operates reliably even during internet outages (source: gridx.ai).

Recent Developments

One of the most significant developments in the past two years was the complete acquisition of Klarsolar by E.ON Energie Deutschland in December 2023. This acquisition enables digital scaling and increased installation capacity, which E.ON CEO Filip Thon highlighted as crucial for the company's future expansion (source: pv-magazine.com). Furthermore, the introduction of the Klarsolar HERO HEMS is seen as an important step towards optimizing energy efficiency in German households.

Working There

Klarsolar offers positions in various fields, including legal, IT, marketing, operations, project management, and sales. The company culture promotes close collaboration within the management team and values employee involvement in implementing the motto "easier and cheaper PV." The employee count of around 150 indicates a dynamic work environment that could further evolve following the acquisition by E.ON (source: klarsolar.de). Current job openings can be found on the company's career page.
