Solar power meter for precision measurement

The Sentry ST530 measures solar irradiance across a 400 to 1100 nanometre spectral range. It captures orientation and tilt angle data for quantitative radiation analysis. The device suits installers, inspectors and researchers who need reliable solar power readings in the field.

Verify spectral range and unit requirements

Confirm that the 400 to 1100 nm bandwidth matches the solar spectrum you intend to assess. Ensure the W/m2 and BTU/ft2?h unit options align with your reporting standards. The meter stores up to 20 data points for later recall.

Integrates with logging and transmission workflows

Automatic backlight and triple-reading display support clear visibility in changing light conditions. Auto transmission measurements streamline data capture without manual intervention. The tool operates as a standalone unit, freeing the user from external loggers during site surveys.

Questions about this item

What comes in the box and is anything extra needed to start measuring?

The meter ships as a single unit in its box; no additional accessories or power sources are listed as required for basic operation.

How do I decide between the available versions or capacities of this model?

The ST530 is offered in one configuration covering the 400 to 1100 nanometre range, so there are no alternative versions or capacities to choose from.

What does the 400‑1100 nm range mean when I use the meter on a rooftop array?

It measures solar irradiance across the visible and near‑infrared spectrum that silicon photovoltaic cells respond to, giving a direct W/m² or BTU/ft²·h reading of the usable sunlight hitting the panel.
