High-fidelity, physics-driven modelling, from PV cells through to solar arrays.
Who We Are
A team of technical experts delivering unrivalled modelling results and speed to solar innovators - in the field and factory.
What We Do
The SunSolve approach applies interdependent optical, thermal, and electrical models. With one change in physical dimension, the advanced modeling system updates automatically, delivering fast, precise, and reliable results.
Grounded in the science of cell manufacturing, SunSolve applies cell-by-cell, timestep-by-timestep rigour through to the system level – enabling confident decision-making through detailed comparison and experimental validation.
Developed in close collaboration with solar scientists, R&D teams, and industry leaders, SunSolve delivers sophisticated analytical tools that explain complex and often counterintuitive field results.
SunSolve’s modelling works seamlessly at both the cell level with SunSolve Power, to the system level with SunSolve Yield, delivering the same precision and reliability across every scale.
At the core of the SunSolve philosophy is clarity. Intuitive software and streamlined visualizations make it easy to interpret device and system behaviour, transforming complex data into immediate insight.
While many PV simulation platforms lag behind industry innovation, SunSolve is already modelling perovskite tandem modules – accurately capturing spectrum and layered absorption effects natively within our analytical engine.
How We Work
We apply our powerful tools, alongside your team,to deliver understanding, solve challenges, and drive smarter decisions.
PhD-level engineers bring deep scientific insight and a passion for accurate simulation to solve problems with precision and purpose.
We translate advanced modelling into real-world impact – helping your team navigate complex data and turn it into confident product and project decisions.
Our collaboration extends beyond an individual engagement – as an addition to your team, we share your goals, urgency, and pursuit of better results.
Our experts get to the heart of underlying problems by revealing what's really happening, why it matters, and how to fix it.

NEWSROOM
Stay connected to the latest features, developments, learning materials, and academic presentations from the SunSolve team and PV industry.
We released SunSolve P90 at ACP Peak 2025 - a free Python API that quantifies uncertainty in energy yield forecasts from PVsyst, SolarFarmer, PVLib, SunSolve and other tools using Monte Carlo simulation.
This post explores how to predict the bifacial gain of AgriPV systems, which can vary from 2% to 50% depending on system design and conditions. We describe SunSolve's ray-tracing method, PVsyst's industry-standard approach, and how they can be used together.
Dr. Radovan Kopecek’s IEEE-PVSC keynote traced the evolution of crystalline silicon solar technology and the barriers overcome along the way, from PERC to TOPCon and back contact. Backed by over 7 GW of global tech transfer projects, his perspective offers a front-line view of PV manufacturing trends and the policies shaping them.
