®Panel, inverter and storage pricing side by side
Price-per-watt and price-per-kWh figures track across module, inverter and battery storage categories, refreshed against real listing and transaction activity on the marketplace rather than a survey.

Real-time Price per Watt
Live pricing indices across panel, inverter and storage classes, refreshed against real marketplace activity.
What this tracks
Broken out by technology where it matters
Where technology meaningfully affects price, TOPCon versus older module construction, for instance, the index separates figures rather than blending them into one misleading average.
Why real-time data matters here
Directly useful for a live bid
A pricing figure refreshed against real activity is defensible in a bid conversation in a way a quarterly industry report can't match.
Your questions, answered.
How is the price-per-watt index calculated?
The index is built from real marketplace activity, aggregating pricing across panel, inverter, and storage listings and transactions to produce a live price-per-watt benchmark rather than a static list price. Because it tracks actual deal flow, it moves with the market and is meant to be usable in a live bid. Categories are broken out so a benchmark reflects the equipment class you are actually pricing.
Does the index break out pricing by module technology, like TOPCon versus HJT?
The index breaks out pricing by technology where the distinction matters to buyers, so different module classes can be compared rather than blended into a single number. That lets a bid reference the relevant cell or module type instead of a generic panel average. Available breakouts depend on how much marketplace activity supports a given class.
How often does the index update?
The index refreshes against real marketplace activity, so it reflects current deal flow rather than a stale quarterly figure. That keeps it directly useful when pricing a live bid. The exact refresh frequency follows the pace of transactions feeding it.
