This panel may show a sampled measurement (e.g., power) and/or a cumulative measurement (e.g., energy generated).
When the sampled measurement is available, a gauge and trend chart will appear.
When the cumulative measurement is available, its value will be shown over the date range indicated.

Key solar radiation components are commonly used when evaluating solar resource at a particular location:
(*Plane-of-array irradiance represents the amount of sunlight that reaches a solar array. Global tilted irradiance (GTI) may be substituted for plane-of-array irradiance if assumptions are made about a solar array's tilt and orientation.)
Solar radiation is an important measurement used to determine both operational performance of photovoltaic (PV) plants and expected performance when siting and designing new PV plants. Generally, a PV plant’s power generation is proportional to solar radiation received by the plant’s PV arrays. When measured properly, on-site solar radiation data can be used to quantify a PV plant’s exposure to sunlight and establish a robust baseline solar resource dataset.
Two common terms are used to describe solar radiation: irradiance and insolation.
