Thousands of professionals choose to work with our solar flux calculator and design software
Streamlining BayWa r.e’s pre-engineering workload
«We needed software that was easy to handle, fast, and detailed. Now, with pvDesign, our developers can design in half an hour. Using AutoCAD or other tools would take one or two days.»
RatedPower speed helps us boost our competitive advantage
«Now we can turn around design documents within hours and minutes to stakeholders, landowners, partners or engineers, to get through our regulatory process. This has allowed us to move projects forward faster.»
A three-in-one software that saves PNE time and resources
«It's easy to use, even for non-technical users. Now, anyone in our offices can efficiently create their own designs, and our German engineers can manipulate anything in our projects remotely since pvDesign is cloud-based.»
Optimizing PV projects and overcome the limitations of legacy software
«We have received a highly professional response when we needed support or training from RatedPower's team. pvDesign helps us optimize our projects and provides us with a significant advantage over our competitors.»
Harnessing pvDesign to carry out invaluable PV equipment analysis
«RatedPower provides us with simplicity and flexibility in our solar projects while requiring fewer resources. Other software options typically demand more resources on our end to complete these calculations.»
Doubling PV project development bandwidth with software
