The short version
- Only HOMER Energy has a free tier, so it costs nothing to try first.
- Each has a real cost: PowerFactory DIgSILENT no prices are published; the product pages only offer Request a Quotation and Demo Request; HOMER Energy now owned by UL Solutions rather than being independent
- They diverge on capability: PowerFactory DIgSILENT covers Load flow calculation, HOMER Energy covers Microgrid optimization.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
PowerFactory DIgSILENT
- No prices are published; the product pages only offer Request a Quotation and Demo Request
- The commercial licence is sold by node count, in tiers of 100, 250, 500 or unlimited nodes
- Functions are sold as a configurable package rather than included, so advanced modules are priced separately
- Support, maintenance and upgrades are included only for the first 12 months of a perpetual licence and then require an annual maintenance contract
- The number of concurrent users on the Multi-User Edition is limited to the number of licences purchased
- A floating licence used on a local machine is time limited to a maximum of 30 days
- Centralised project data on Oracle, SQL Server or PostgreSQL requires the Team Edition; Single-User and Multi-User editions use a local SQLite database
- Education licences are capped at 50 nodes and forbid commercial use
- Student licences are capped at 50 nodes, are cloud softkey only and expire 12 months from issue
HOMER Energy
- Now owned by UL Solutions rather than being independent
- Split into three separate products, HOMER Pro for off-grid and microgrids, HOMER Grid for bill optimisation and HOMER Front for utility-scale, so the right one depends on project type
- Pricing is not shown on the product pages
