CLUSTER SOLAR-WEB-ENERGY · 42 ENTRIES · EARLIEST ENTRY 2025-05-16
Solar savings and sizing calculators
This cluster consists of web and mobile tools that estimate solar energy potential, size PV and battery systems, and calculate savings, payback, and ROI for residential, RV, and commercial users. The dated history is thin: one entry in April 2023, followed by single entries in May 2025, June 2025, October 2025, and May 2026, showing no clear trend before the index began. All traction leaders (urja-saathi, voltsage-testing, solar-savings-calculator-sp-new-view) have zero stars, indicating minimal user engagement or visibility.
Entry timeline
ENTRY TIMELINE
Each bar is the month a member carries, which is a creation date where the source published one and a crawl date otherwise. Nothing in the index was found before 11 August 2026, and coverage broadened sharply on 14–15 August, so a bar from then on reports how much we found that month, not how much was built; an earlier bar reports how far back a member's own source dated it — not how long we have been watching.

Two labels per entry, never collapsed into one: how it was built, and who stands behind it. Counted over the 2 listed below. Unlabelled means nothing has decided yet — not that the answer is small.

Ranked by traction, highest first, and paged 20 at a time — this is a window on the cluster, never the whole of it. Ties are broken by a stable id so a product cannot appear on two pages or fall between them. Browse every cluster.
