The short version

  • Only SMA Energy has a free tier, so it costs nothing to try first.
  • Each has a real cost: Helioscope licences are single user, so each designer needs their own; SMA Energy requires SMA Premium subscription for advanced automation features
  • They diverge on capability: Helioscope covers PV system design, SMA Energy covers Real-time monitoring.
  • Prices and features above were last checked on 30 August 2026.

Where each one falls short

Documented limitations, not opinions. Every one is a constraint you would hit in normal use.

Helioscope

  • Licences are single user, so each designer needs their own
  • Projects are capped at 10 a month on both Basic and Pro
  • System size is capped by plan, at 1.25 MW DC on Basic and 5 MW on Pro, so a larger array forces an upgrade regardless of project count
  • Trackers, LIDAR modelling and API access sit on the higher tiers
  • Enterprise is priced per project with no published figure

SMA Energy

  • Requires SMA Premium subscription for advanced automation features
  • SMA Sunny Portal monitoring has data delays and does not guarantee real-time updates
  • Limited scalability for larger residential or commercial installations beyond 18.9 kWh
  • Requires all devices to have latest software versions and compatible communication protocols

Answered from the vendors’ own pages

Helioscope: What is the starting price for HelioScope?

HelioScope Basic plan costs $159 per month per license with annual billing at $1,620/year (15% discount). The Pro plan is $259/month or $2,640/year. Each license covers 1 user. Source: https://helioscope.aurorasolar.com/pricing

Helioscope: How many projects can I design monthly with HelioScope Basic and Pro?

Both Basic and Pro plans include 10 projects per month, equaling 120 projects per year. The project allocation is the same across both tiers; the difference is in design capability (1.25 MW for Basic vs. 5 MW for Pro). Source: https://helioscope.aurorasolar.com/pricing

Source
SMA Energy: What are the system requirements for SMA Energy?

SMA Energy requires compatible SMA inverters, SMA Energy Meter for consumption tracking, and communication protocols like Modbus or Speedwire for connectivity. All devices must have the latest software version, and a network connection is required for remote monitoring through SMA Sunny Portal.

Helioscope: What is the maximum solar design capacity by HelioScope tier?

HelioScope Basic supports designs up to 1.25 MW DC, Pro supports up to 5 MW DC, and Enterprise supports unlimited designs up to 30 MW DC. Accuracy within 1% of PVsyst modeling is maintained across tiers. Source: https://helioscope.aurorasolar.com/pricing

Source
SMA Energy: Does SMA Energy work offline?

SMA Energy systems can continue generating electricity offline, but remote monitoring and cloud-based optimization through SMA Sunny Portal require internet connectivity. If communication fails between devices, inverters reduce output power to 0 percent as a safety fallback.

Source
SMA Energy: What is the maximum system size for residential installations?

SMA systems typically support a maximum residential configuration of 18.9 kWh battery storage, which is suitable for most single-family homes but may be insufficient for larger properties or commercial applications.
