How to apply for Praktikant:in (m/w/d) Technische Planung Photovoltaik - 1KOMMA5° Handwerk - Remote

1KOMMA5°

About 1KOMMA5°

1KOMMA5° builds a software platform called Heartbeat that connects solar panels, batteries, heat pumps, and charging stations into a virtual power plant. The company also offers a one-stop shop for buying and installing these energy systems. Working here means contributing to making homes climate-neutral and linking customers to the cheapest, cleanest electricity tariffs.

About the role

As a technical planning intern for photovoltaics, you learn to plan and visualize PV systems using the company's planning software. After a short onboarding, you plan independently and help create custom offers for customers. You also support the team in daily PV planning tasks and gradually become a go-to person for technical questions.

A typical day

You start by checking new customer requests and planning PV systems using the company's software. You create or revise offers and coordinate with team members on technical questions. You might also join a short team meeting to discuss ongoing projects and learn about grid registration steps.

Who 1KOMMA5° is looking for

  • You are enrolled in a technical study program (e.g., electrical engineering, renewable energy, mechanical engineering, or similar) or have a strong technical affinity.
  • You are interested in photovoltaics and want to learn how to design and visualize PV systems.
  • You are comfortable using planning software and can work independently after training.
  • You have good German language skills (the job description is in German) and can communicate clearly with team members and customers.

Tips for this application

  • Write your application in German, since the job description and likely team communication are in German.
  • Mention any experience with PV planning software, CAD tools, or technical drawing—even from university projects or hobbies.
  • Highlight your interest in the energy transition and decentralized energy systems, as 1KOMMA5° focuses on CO2-neutral buildings.
  • Explain that you can work remotely and are self-motivated, since the position is remote and involves independent planning after training.
  • Show that you understand the full process from planning to offer creation and grid registration, not just the planning step.

What to cover in your cover letter

Emphasize your technical background and any experience with planning or visualization tools. Explain why you want to learn PV planning and how you can become an independent planner quickly. Show that you are interested in the entire process, including offer creation and grid registration. Mention that you are comfortable working remotely and communicating with a team.
