If you've driven through a German suburb lately and noticed more solar panels glinting on rooftops, there's a good chance 1KOMMA5° had something to do with it. Named after the critical 1.5°C threshold from the Paris Climate Agreement, this fast-growing company is on a mission to make that target achievable — not through abstract policy, but through concrete, rooftop-by-rooftop climate action.
What Does 1KOMMA5° Do?
1KOMMA5° is a vertically integrated clean energy company that helps homeowners and businesses across Germany and Europe decarbonize their energy use. Their core offering combines solar photovoltaic systems, battery storage, heat pumps, and EV charging infrastructure into one intelligent, connected energy ecosystem. Rather than simply installing individual components, 1KOMMA5° designs holistic energy solutions — often tied together through smart software that optimizes when and how energy is produced, stored, and consumed.
The company has grown rapidly since its founding, acquiring and integrating local installation businesses across Germany to build a nationwide network of certified electricians, solar installers, and heating specialists. This "buy and build" approach has allowed 1KOMMA5° to scale quickly while maintaining the hands-on technical expertise needed to deliver quality installations at the local level.
Climate Impact: More Than Just Solar Panels
Germany's Energiewende (energy transition) depends heavily on decentralized, residential-scale renewable adoption — and that's exactly where 1KOMMA5° has planted its flag. By making solar-plus-storage systems and heat pumps accessible and easy to install, the company is directly reducing household reliance on fossil fuels for both electricity and heating, two of the largest sources of residential carbon emissions.
Their smart energy management platform also plays a quiet but important climate role. By intelligently managing when batteries charge, when EVs draw power, and when excess solar energy is fed back to the grid, 1KOMMA5° helps balance renewable energy supply and demand at a granular level — a critical piece of the puzzle as more intermittent renewable energy comes online. In short, they're not just selling hardware; they're helping build the smarter, more flexible grid that a renewable-powered future requires.
Current Opportunities at 1KOMMA5°
2024 has been a year of continued expansion for 1KOMMA5°, and their open roles reflect a company scaling across multiple functions — from hands-on technical work to corporate operations. Currently open positions include:

This mix of roles — spanning logistics, sales leadership, HR, working student positions, and skilled trades — shows just how many different career paths lead into the renewable energy sector. Whether you're a recent graduate looking for a working student role, a tradesperson skilled in landscaping or heat pump installation, or an experienced sales leader, there's likely a way to plug into 1KOMMA5°'s mission.
Employees often describe the culture as fast-paced and entrepreneurial, given the company's rapid growth trajectory. Because 1KOMMA5° operates across many German cities — from Bremen to Berlin to Homburg — there are opportunities to work close to home while still being part of a larger, ambitious national mission.
Why Climate-Minded Professionals Should Take Notice
For job seekers who want their daily work to have a tangible, visible climate impact, 1KOMMA5° offers something rare: the chance to see your work installed on an actual rooftop, actually reducing a household's carbon footprint. Unlike many climate-adjacent roles that operate one step removed from physical impact, positions at 1KOMMA5° — whether in sales, logistics, or installation — connect directly to real homes switching to clean energy.
The company's rapid growth also means genuine opportunities for career advancement, especially for those who join now and grow alongside the organization. And with open roles across technical trades, corporate functions, and student positions, there's an entry point for climate-motivated professionals at nearly any career stage.
As Germany continues its ambitious push toward renewable energy targets, companies like 1KOMMA5° are the ones translating national climate policy into installed reality — one solar panel, one heat pump, one smarter home at a time.
