Solar yield calculations are based on real localised irradiance data, factoring in the exact orientation, tilt, and shading conditions entered during the design. The ROI model incorporates current energy tariffs, applicable subsidies, and hardware degradation curves to build a 25-year projection. For the Dutch market, additional levers are available including feed-in cost modeling and salderingsregeling phase-out scenarios. The methodology is consistent across every consultant, so the numbers your team presents reflect the same underlying model every time.

OpusFlow tracks backorder status at the order line level and feeds the expected delivery date directly into project scheduling. That means a delay from a supplier surfaces in the planning view before it becomes an install-day problem, giving your team time to source an alternative or reschedule rather than discovering the shortage on the morning of the job.

No. We care more about the right mindset than sector knowledge. You’ll learn the industry quickly by working with the product and the team every day. What we do look for is curiosity, ownership, and the drive to get things done.

Yes! OpusFlow connects with a wide range of accounting software. We have extensive experience integrating with platforms like Exact, Holded and Quipu, and through our Zapier integration you can link virtually any financial package.

Yes. The heat pump calculator sits inside the same quotation flow as the PV Designer and battery calculator, so your consultant can cover solar design, battery sizing, and heat pump assessment in a single appointment and present a combined proposal with a full renewable energy picture — including a joint ROI calculation — in one branded PDF. No switching between tools, no separate follow-up visits.

OpusFlow is an all-in-one business management platform built specifically for solar, heatpump, battery, charging stations and other sustainable energy installation companies. It connects your sales, operations, planning, warehouse, and finance in one system so your whole team works from the same data, not separate spreadsheets messaging apps or other external apps or software.

Yes. The calculation follows the DIN EN 12831-1:2017 methodology, which is the recognised European standard for determining building heating load. It covers per-room heat loss including U-values, thermal bridges, ventilation, airtightness, and surface adjacency. The output is a DIN-compliant PDF report that includes a per-room breakdown, total heat demand, and the final hardware recommendation — suitable for use as supporting documentation with the customer or for your own internal records.
