Sunlight
Irradiance, beam and diffuse light, and year-to-year resource variability across 40 benchmark markets. NASA CERES and MERRA-2.
Open lensSolar Analytica joins sunlight, atmosphere, climate, electricity systems and market value into a versioned global record. Compare places and time periods, then open the source, observation window and limits behind every reading.
One planet does not produce one solar answer. Resource, weather, grids, prices and constraints are kept separate until the evidence supports the join.

Solar share of electricity, held to the same annual comparison basis as the other systems in this field.
Reference points locate the climate lens; they are not national resource averages. The wider record spans 40 climate markets and 92 priced cities.
Hold the technology constant and move the location. Expected output, resource uncertainty and long dry spells shift around it. This is the beginning of the global lens: comparable questions, place-specific answers and the evidence boundary still attached.
Choose one market. The surface holds everything else still so the numbers remain comparable.

Longest observed run without a qualifying daily event
Evidence note: yield is modeled; irradiance variability and rain gaps are measured over 2001-2023. P90 covers resource variability only. A 5 mm rain event is a consistent climate threshold, not a guarantee of module cleaning.
Solar potential is not an irradiance ranking. The useful reading appears where physical conditions, electricity systems and market rules meet, without collapsing them into one false score.

Open lensMost public data surfaces show the current answer. Solar Analytica preserves enough history to ask what the source said, what later changed and where credible records disagreed. A wider Global Solar Memory remains a research programme until its first reproducible edition is published.
Read the evidence methodAustralia / high-resolution laboratory
The SWIS and four NEM regions form Solar Analytica’s highest-resolution laboratory. Move between demand, price, ramping, negative-price and rooftop-solar records; every view retains its source, date and calculation. This is the proving ground for methods intended to travel.

Evening ramp in Queensland is 39.1% below its prior 29-observation median.
2,152 MW on 2026-08-22, against 3,535 MW. Ranked by robust distance from the retained median; this is observed context, not a forecast or causal claim. The baseline uses the requested 30-day window.

The research desk connects climate, grids, build-out, standards and market value while keeping source boundaries visible. Each release is dated against the evidence it contains.
A serious energy decision moves from the world and its markets, to the exact product, to the job in front of you. Each altitude has its own property and its own evidence boundary.
