Solar Design Software
Independent reviews, alternatives and pricing breakdowns for every major solar design tool, written by engineers who run them on real projects.
Solar design software shapes every downstream cost on a project: BOQ accuracy, energy yield, shade losses, AHJ acceptance and bankability. Picking the wrong tool, or paying for a tier you do not need, quietly bleeds margin every quarter. This hub collects our long-form comparisons, alternatives lists, pricing breakdowns and workflow guides for Aurora, PVsyst, Helioscope, OpenSolar, PVCase, Scanifly and the rest of the stack. Every article is written by engineers from the Heaven Designs team who deliver design packages in these platforms every day. Start with the comparisons if you are evaluating, the pricing posts if you are renewing, or the alternatives lists if a vendor change is on the table.
