Mid-2025 focused on performance and reliable document delivery for Solar Proof. This release sped up large-system design, moved proposal documents onto faster and more dependable cloud storage, added more built-in finance maths and in-app help, and strengthened the underlying platform. Here's everything that shipped, grouped by area, with what each change means for your solar business.
What changed in this mid-2025 Solar Proof update?
In short: more efficient panel drawing for large arrays and faster commercial design, AWS S3 storage with direct proposal PDF delivery, lease payment calculations and a manufacturers API, an in-app help-videos module, and Docker for a more reliable platform. Each is detailed below.
How is large-system design performance improved?
- More efficient panel drawing for larger arrays — the design canvas now renders large panel layouts far more efficiently, so big commercial systems draw and update quickly. Smoother, quicker designs on large jobs. See auto stringing for compliant string design and run the numbers with the commercial solar calculator.
- Faster large-system design & disappearing-panel fix — overall performance on big systems is improved, and a bug where panels could vanish from the design has been fixed. Reliable, responsive design even on large commercial arrays. Related: combining PV array groups for performance.
How are proposal documents delivered and stored?
- AWS S3 integration — documents are now stored on Amazon S3, giving faster, more scalable and more reliable file storage. Your proposals and files are always available and quick to load.
- Direct proposal PDF delivery (no proxy) — proposal PDFs are now served directly rather than through a proxy, removing a bottleneck and a point of failure. Faster, more reliable proposal downloads for you and your customers.
- Image-in-PDF fixes — images now embed correctly in generated PDFs, so proposals look right every time. No missing or broken images in the final document.
What finance and help features were added?
- Lease payment calculations — lease repayment maths is now built in, so you can present leasing as a finance option with accurate figures. More finance choice on every quote. See finance visuals in the charts available in Solar Proof.
- Manufacturers API — a manufacturers API keeps equipment and product data flowing in from suppliers. Up-to-date product data with less manual maintenance. More in the API and integration guide.
- In-app help-videos module — short how-to videos are now built into the app, giving guidance exactly where you need it. Learn features without leaving your work.
What infrastructure improvements shipped?
- Docker integration — the platform now runs in a containerised setup, improving consistency, deployment and overall reliability. A more stable, dependable platform behind the scenes.
