Running a solar or heat pump installation business gets harder as you grow. More leads come in, projects overlap and your team starts relying on spreadsheets, WhatsApp messages and separate tools just to keep up, especially as the German solar market continues to expand. What used to feel organised now feels scattered. Quotes slow down, planning becomes reactive and it gets harder to see where projects are stuck.
If your systems can’t keep pace with your workload, it might be time to look beyond HERO and explore stronger HERO alternatives, platforms built for the full installer workflow.
Why look beyond HERO?
HERO is a strong ERP tool for general craft businesses, but solar and heat pump installers need more. Your work depends on fast quotes, accurate designs and clear communication between sales, planning and field teams. When these live in separate tools, everything slows down.
Here’s what usually goes wrong:
- Information gets lost between systems
- Quotes take too long to send
- Teams work in silos and rely on WhatsApp to fill the gaps
- Managers can’t see what is stuck or why
- Customers wait longer for answers
This is when installers start looking beyond HERO. Not because the software itself is “bad”, but because it was never built around the full solar workflow. Modern installer platforms bring sales, design, planning and after-care together in one place so every project moves with fewer mistakes and less manual work.
If you want fewer systems, fewer handovers and a smoother customer experience, it makes sense to explore alternatives made for growing renewable businesses.
How we selected these HERO alternatives
Choosing a HERO alternative is a big decision, so we focused on criteria that matter most to installers in the German market. The goal was simple: find tools that reduce complexity, improve collaboration and support your full workflow from first contact to final installation.
Here’s what we looked for:
- Solar-ready workflows: Tools had to support the full installer process from lead to installation without forcing extra systems
- German market fit: Platforms needed to serve German installers with language, support or compliance features
- Real time savings: We focused on software that cuts manual work and speeds up quoting, planning or project delivery
- Scalable for growing teams: Solutions had to fit both smaller companies and installers adding more crews or services
- Easy for teams to adopt: Clear interfaces and simple onboarding were essential so everyone can use the system with confidence
- Reliable documentation and compliance: Preference for tools that help navigate EEG, KfW and DIN requirements
One Platform to Run Your Entire Installation Business
Manage leads, projects, stock, and invoicing — everything in one smart system built for sustainable installers.
1. OpusFlow: One of the leading HERO alternatives for installers
OpusFlow, as one of the HERO alternatives, is built for installers who want one connected workflow instead of juggling separate tools for sales, planning, stock and installation. Everything sits in a single system so your team always works from the same information. Quotes move straight into projects, materials are tracked in real time and every department sees what needs to happen next without chasing updates.
For growing solar and heat pump companies, this clarity makes the biggest difference. Instead of losing time to handovers and manual steps, your team focuses on delivering jobs faster and with fewer mistakes. OpusFlow replaces tool chaos with one simple way of working that fits how installers actually operate. That is why it is considered as a HERO alternative.
Advantages of OpusFlow
- Keeps sales, planning, stock and installation in one connected workflow
- Helps teams work faster with fewer handovers and no duplicate data
- Easy for all departments to use with a clean interface and simple onboarding
Disadvantages of OpusFlow

2. Odoo: A flexible ERP among popular HERO alternatives
Installers, who are comparing HERO alternatives, often consider Odoo. It is a modular ERP that lets companies build their own setup from dozens of apps like CRM, sales, inventory, accounting and field service. It gives installers a flexible way to manage operations without committing to a large enterprise system. Many teams choose Odoo because it’s affordable, well-supported and can grow with the business.
Even so Odoo is considered as a striking HERO alternative, it is not designed around solar workflows. To handle quoting, PV design, technical checks or installation planning, most installers need extra apps, custom fields or third-party tools. It can work well with the right configuration, but businesses looking for an out-of-the-box solution often find the setup and maintenance more demanding than expected.
Advantages of Odoo
- Wide range of modules covering most business processes
- Flexible setup that can grow as the business grows
- Affordable price point with many community resources
Disadvantages of Odoo
- Not solar-specific so requires customisation to fit installer workflows
- Setup and maintenance can be time consuming for non-technical teams
- Quoting and design tools are not integrated into the core system
3. Autarc: A planning-focused HERO alternative
Autarc is a Germany-based software platform focused on technical planning and documentation for renewable energy installations, particularly PV systems, heat pumps and electrical infrastructure. Among modern HERO alternatives, it positions itself as a specialist for engineering and compliance workflows rather than a full business ERP.
Autarc is a good fit for companies that already manage sales and project coordination elsewhere, but want to reduce risk, errors and manual effort in technical planning and approval workflows.
Advantages of Autarc
- Strong focus on German regulations and standards
- Specialised technical planning

How to choose the best HERO alternative
Choosing the right software shapes how your team works every day, so it helps to focus on what actually keeps projects moving. The best HERO alternative should reduce the number of tools you use, remove manual steps and give everyone a clear view of what needs to happen next. Most importantly, it should fit the way your solar and heat pump installers work, not the other way around.
Here’s what to look for when comparing your options:
Solar-specific workflows and compliance
Your ERP software should follow the same steps your team follows every day. Look for tools built around the full solar workflow so leads, quotes, design, planning and installation all move together without manual handoffs.
German compliance and tariff modeling
The platform should support EEG tariffs, KfW programs and the documentation your customers expect. Accurate financial models help you avoid mistakes and give customers clear numbers from the start.
Automation and time savings
Good software reduces repetitive work. Automations for reminders, follow-ups, stock updates or project handoffs save hours each week and help your team stay consistent even during busy seasons.
Built-in quoting and design tools
Fast quoting is critical. When design and pricing live inside your system, proposals go out sooner and with fewer errors. This also keeps your sales and planning teams aligned around the same information.
Scalability and customisation
As your business grows, your software should grow with you. Choose a platform that supports more crews, more jobs or new product lines without forcing a full rebuild.
Integrations with your workflow
If you rely on external tools, make sure your new platform connects with them in a simple and stable way. Integrations help avoid duplicate data and keep your process clean.
Local support and language
Teams work better when the software speaks their language and support is easy to reach. Look for platforms with German-language interfaces or active support for the DACH region.
