Where each one falls short

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

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
