Insight on stellar power

Engineering, investment and grid analysis from the team forecasting, deploying and orchestrating solar at every scale.

The Science of Macro-Scale Yield Forecasting

How we turn thirty years of irradiance data, satellite imagery and machine modelling into generation forecasts banks will underwrite.

Storage economics have shifted. We break down the four value streams that decide whether a battery pays for itself — and how fast.

From load profiling to PPA structuring, a procurement-grade walkthrough of deploying solar across a commercial portfolio.

Tens of thousands of home batteries acting as one power station. How VPPs work, what they pay, and why the grid needs them.

The century-old model of central generation is giving way to millions of cooperating nodes. What that means for everyone connected.

Rebates, certificates and the parallel market for green attributes — a clear-eyed look at what your generation is really worth.

Insight is good. A bankable yield model for your roof, site or portfolio is better.
