Built for the environment it measures
SriWatt devices record real sunlight, surface heat and shading at your actual site — second by second, not from a 4 km satellite cell.

The four types of data inaccuracy
Bad input data quietly wrecks solar forecasts — and the finance that depends on them. These are the four most common culprits, and each is something a device on the site measures instead of guessing.
Bad metadata
30% of projects have missing or wrong tilt/azimuth data — enough to throw the forecast off by more than 15% (NREL).
Micro-shading
A vent, pole or single wire shading just 1–2% of a system can cut its output by 30–50%.
Albedo guesswork
The default “0.2” ground-reflectivity assumption misses up to 12.4% of the gain bifacial panels actually capture.
Soiling losses
A flat 2% dust assumption is fiction. In dry climates losses reach 35%, building ~0.5% a day.
$5B wasted every year
Roughly 94% of solar pre-sales spend is lost, and lenders add 10–35% to finance costs — almost all of it for want of real, on-site data.
One small device. Three steps.
Records real sunlight, surface heat and shading at the actual site — second by second.
Our algorithm learns the gap between simulation and site reality, then corrects the data.
You get a clear, bank-ready P50/P90 yield report. Faster approvals, fewer arguments.
Retire the industry's "golden module" guesswork
Simulation software like PVsyst runs on .pan files — a module's idealised performance curve, built from manufacturer or lab-bench testing. It's the same static file used on every site, and it typically overstates real-world yield by 1–3%. A deployed SriWatt device replaces it with a .sri file: the module's actual, measured performance at that exact site.
.pan files
The industry-standard format for PVsyst and similar simulation tools.
- Idealised curve from manufacturer or lab-bench testing
- One static file, reused on every site regardless of local climate
- A documented 1–3% optimism gap against real-world yield
- Never updates once it's issued
.sri files
Generated on site by a deployed SriWatt device.
- Built from I-V sweeps captured on the installed module, on site
- Measured performance ratio, specific yield and degradation, with a confidence interval
- Tamper-evident — every file carries an integrity hash and its full provenance
- Updates over time into a location-specific digital twin

Numbers from the field, not from a deck
Field-tested on 1,200 commercial and industrial solar sites.
“The trust it builds with the customer is priceless. Showing them real data from their own roof removes almost all performance objections.”
— Pilot participant
“The SriWatt report isn’t just a sales tool — it’s a financing tool. It dramatically sped up our talks with the banks.”
— Pilot participant
“A near-40% conversion rate is unheard of in this industry. The tool pays for itself many times over.”
