PVsyst vs. HelioScope Frequently Asked Questions

Blog Main

HelioScope and PVsyst each offer unique capabilities, but understanding their differences and how to align their outputs is essential for solar professionals seeking to maximize project outcomes. In the first post of our series — Optimizing commercial solar designs — we looked at key features of and differences between each system. We also illustrated a step-by-step example of how to align their outputs.

In this post we’ll cover some of the most common questions users have about PVsyst and HelioScope.

Question: What is the maximum energy difference between PVsyst and HelioScope if inputs are aligned correctly?

Answer: When properly aligned, the energy output difference between PVsyst and HelioScope should be within about 1%. This involves setting up condition sets in HelioScope that mirror those used in PVsyst, ensuring high reliability in comparative energy production estimates.

Question: Is it necessary to use both PVsyst and HelioScope for C&I solar design, or is HelioScope sufficient?

Answer: Third-party financiers often require PVsyst for larger projects due to its recognized status as a bankable solution. However, HelioScope is accurate enough to be considered bankable and is sufficient for many projects, particularly where internal financing solutions are used. HelioScope’s rapid design capabilities and accuracy make it a strong contender for comprehensive project simulations.

Question: Are there training materials available for HelioScope users?

Answer: Yes. A range of pre-recorded HelioScope training materials and walkthroughs are available in the Help Center. These cover various topics to help users maximize the tool’s capabilities. Custom plan users also have access to hands-on training sessions with account executives and customer success managers.

Question: Can HelioScope handle wiring losses and different wire gauges for larger projects?

Answer: Yes. HelioScope allows users to change the gauge of copper or aluminum wire being used, which can significantly impact larger projects. Unlike some platforms that use a flat derate value, HelioScope models both AC and DC systems, enabling precise adjustments. You can also upload custom weather data sets, enhancing the tool’s flexibility for various project conditions.

Question: Does HelioScope support simulations for international regions like Norway?

Answer: Yes. HelioScope supports international users and can provide accurate simulations for various regions, including Norway. HelioScope has a significant international customer base, with about 60% of users operating outside the United States. Custom demonstrations and support are available to address specific regional needs.

Question: What is the maximum system size HelioScope can handle, and can it be used for utility-scale power plant design?

Answer: HelioScope can design systems up to 15 megawatts, although the optimal simulation speed is for systems up to 5 megawatts. For larger utility-scale projects, systems can be divided into increments of 15 megawatts each. This modular approach allows for detailed simulations and aggregate production calculations.

Question: Is there a way to get a free trial of HelioScope?

Answer: Absolutely! You can sign up for a free trial directly on the HelioScope website without needing to provide credit card information. This allows new users to explore the platform’s features and capabilities.
