Frequently Asked Questions about the SunEye


SunEye and PV Designer Software and Documentation:

Windows desktop companion software, supports SunEye models 100, 110, and 210. Software includes PV Designer.

On new installations, click ‘skip’ when prompted to connect the SunEye to your PC. When the installation completes your SunEye should connect normally.

If you see the message: “Waiting for device connection” or “Error connecting to your Solmetric SunEye Device”, make sure you are running SunEye desktop app version 4.91.8447 (see link above).

Application Notes/Articles

Accurate estimates for solar production require accurate shade measurements. Getting accurate and consistent shade measurements requires the right tools and the right process for data collection and reporting. This document is intended to describe best practices in the measurement of shade, and to facilitate a common approach within an organization and across multiple organizations. It includes details about using the user interface of the SunEye-210 as well as the process for how and where to make the measurements on site.

This app note will help you get the most out of your SunEye-210 compass.

This article addresses recent developments and trends in residential solar site measurements, including tools and best practices for measuring roof dimensions and shade, estimating system performance, and evaluating the impact of solar leasing options and performance guarantees on site measurement approaches.

This application note describes the details of how to extract the SunEye data and input it to either the CSI Calculator or the NSHP Calculator. The Solmetric SunEye measures both solar access and obstruction elevation angles so it provides the data necessary for either calculator.

The Solmetric SunEye provides complete solar access and shade analysis in an integrated hand-held tool that can help optimize solar panel system design and installation. This note describes how to measure and account for orientation when using the SunEye.

A basic introduction to solar access and shade measurements using the Solmetric SunEye. Also included are descriptions of new features for measuring on metal roofs and with an extension kit.

Improve system performance and energy harvest projections with a thorough site evaluation that includes shading analysis and insolation quantification.

The normal way of aligning the SunEye is to align it using the compass to point South. “Align with Target” mode provides an alternative alignment to a reference azimuth using other visual information available at the site.
