This report provides a desktop glint and glare assessment to support the Development Application for the project. It provides:

• Identification of potential receptors of glint and glare from the proposed solar farm; • Assessment of the glint and glare hazard using the Solar Glare Hazard Analysis Tool

(SGHAT) GlareGauge analysis; and • Recommended mitigation measures to reduce potential glint and glare impacts.

1.2. Glint and Glare Glint is defined as a momentary flash of bright light, while glare is a continuous source of excessive brightness relative to ambient lighting (Federal Aviation Administration (FAA), 2018) The GlareGauge analysis used to assess the glint and glare hazard (see Section 3) was run with a simulation interval of one minute, as sunlight reflection from PV modules typically lasts for at least one minute. Glint, which lasts for less than one minute, is unlikely to occur from the sun based on how slowly the sun and modules move, so has not been considered further in this assessment.

September 2019


• Solar photovoltaic (PV) modules are designed to absorb as much light as possible to maximise efficiency (generally around 98% of the light received). To limit reflection the modules are constructed from dark, light absorbing material and the glass is treated with an anti-reflective coating. As a result, the glare generated from PV modules is lower than from many other surfaces, including cropping/grassland and concrete (an albedo of 20% is typically assumed for PV modules, compared to 25-30% for grass and up to 25% for concrete; Ramirez & Munoz,

2012).

However, the glass modules and metal frames still have the potential to generate glare. This needs to be assessed to ensure that visual receptors such as road users, nearby buildings, air traffic control towers and aircraft pilots are not impacted by the development of solar farms.

2. PROJECT DESCRIPTION

ITP Development is proposing to construct a solar farm with a DC capacity of 6.1 MWp and AC output of 5 MW, on an approximately 78.2 ha site that is currently used for grazing.

There are to be approximately 16,000 solar modules installed on around 200 mounting structures running north to south. Each row of solar photovoltaic (PV) modules will rotate to track the sun across the sky from east to west each day. The hub height of each tracker will be around 2 m with the peak of the modules reaching a height of approximately 4 m when the array is fully tilted to 60 degrees from horizontal. The general arrangement of the solar farm is shown on drawing ORA2B G-210, and the array tracker details on drawing ORA28-E-341.

The solar farm will also comprise two 2.5 MW inverter stations. These inverters are to be located within the array and are each mounted on a 20-foot skid. Each of these inverter stations incorporate the high voltage switchgear and transformers. The arrangement of the inverter station skid is shown in drawing ORA28-E-430.

The mounting system is constructed on piles that are driven in to the ground. During construction there is expected to be 50 personnel on site working from 7 am --4 pm Monday to Friday. The construction is expected to take approximately 3 months. Once operational the site will be unmanned. Maintenance is expected to be carried out quarterly by a crew of 2-3 people.

Solar panels and related infrastructure will be decommissioned and removed upon cessation of operations. This is likely to occur within two years of the end of the project. The site will be returned to the pre-development land use.

3. ANALYSIS

Glint and Glare Assessment of the Orange Community Renewable Energy Park

3.1 Overview In a fixed-tilt PV array the angle of incidence at which direct sunlight hits the PV modules varies as the sun moves across the sky. It will be smallest around noon when the sun is overhead and largest in the early morning and late afternoon when the sun is near the horizon. If the PV array is mounted on a single-axis tracking system as proposed in this project, the variation in the angle of incidence will be much smaller since the modules rotate to follow the sun. The main variation will be seasonal, i.e. because the sun is higher in the sky during summer and lower during winter. A PV array that is mounted on a tracking system therefore has less potential to cause glare.

The SGHAT was developed by Sandia National Laboratories to evaluate glare resulting from solar farms at different viewpoints, based on the location, orientation and specifications of the PV modules. This tool is required by the United States FAA for glare hazard analysis near airports and is also recognised by the Australian Government Civil Aviation Safety Authority (CASA)

The GlareGauge analysis uses SGHAT to provide an indication of the type of glare that can be expected at each potential receptor. Glare is indicated by three colours according to severity:

• Green glare: Low potential for temporary after-image; • Yellow glare: Potential for temporary after-image; and • Red glare: Retinal bum, not expected for PV.

The parameters used in the SGHAT model for the project are detailed in Table 2. GlareGauge default settings were adopted for the analysis time interval, direct normal irradiance, observer eye characteristics and slope error. The heights of the observation points were assumed to be 1.2 m for a road user (i.e. sitting in a car) and 1.5 m for a person.

• 3.2 Potential Receptors For this project, visual receptors within 2 km of the site were considered including residences and road users. A 2-km radius from the site was considered appropriate based on it being highly unlikely for glint and glare impacts at distances greater than this. As shown in Figure 2, 19 residential observation points were identified as potential visual receptors of the site. The potential for glare was also assessed along four different road routes.

While there were a greater number of residential/commercial properties considered, many were discounted based on large stands of trees and other structures which will act as visual barriers between the site and receptor.

The Orange Regional Airport is located approximately 17 km southeast of the site so was not considered a potential visual receptor.

• 3.3 Assumptions The visual impact of solar farm development depends on the scale and type of infrastructure, the prominence and topography of the site relative to the surrounding environment, and any proposed screening measures to reduce visibility of the site. Some potential viewpoints were discounted because of significant existing features such as trees or buildings, however minor screening such as roadside vegetation was not assessed in detail. The GlareGauge analysis results are therefore considered conservative as the model assumes there is no screening. It is noted that the site is almost entirely cleared with only a few trees within the property.

Atmospheric conditions such as cloud cover will also influence light reflection and the resulting impact on visual receptors. Varying atmospheric conditions have not been accounted for in the GlareGauge analysis. The GlareGauge analysis assumes clear sky conditions, with a peak direct normal irradiance (DNI) of 1,000 W/m? which varies throughout the day.

3.4 Results The results of the GlareGauge analysis (attached in Appendix A) at each of the observation points are summarised in Table 3. None of the residences or road users are expected to experience any glare from the solar farm. Many residences will also not have direct view of the solar farm due to visual obstruction from trees and other structures.

4. SUMMARY

- . .. . . .. . . .. . . ..

The results of the GlareGauge analysis indicated that the selected observation points are unlikely to receive glare from to the proposed solar farm. Road users approaching the solar farm along Mitchell Highway, or using Thompson Rd, Griffin Rd or the unnamed road immediately east of the solar farm, are also not expected to experience any glare.

Assumptions

"Green" glare is glare with low potential to cause an after-image (flash blindness) when observed prior to a typical blink response time.

"Yellow" glare is glare with potential to cause an after-image (flash blindness) when observed prior to a typical blink response time.

Times associated with glare are denoted in Standard time. For Daylight Savings, add one hour. Glare analyses do not account for physical obstructions between reflectors and receptors. This includes buildings, tree cover and geographic obstructions. Several calculations utilize the PV array centroid, rather than the actual glare spot location, due to algorithm limitations. This may affect results for large PV footprints. Additional analyses of array sub-sections can provide additional information on expected glare. The subtended source angle (glare spot size) is constrained by the PV array footprint size. Partitioning large arrays into smaller sections will reduce the maximum potential subtended angle, potentially impacting results if actual glare spots are larger than the sub-array size. Additional analyses of the combined area of adjacent sub-arrays can provide more information on potential glare hazards. (See previous point on related limitations.) Glare locations displayed on receptor plots are approximate. Actual glare-spot locations may differ. Glare vector plots are simplified representations of analysis data. Actual glare emanations and results may differ. The glare hazard determination relies on several approximations including observer eye characteristics, angle of view, and typical blink response time. Actual results and glare occurrence may differ. Hazard zone boundaries shown in the Glare Hazard plot are an approximation and visual aid based on aggregated research data. Actual ocular impact outcomes encompass a continuous, not discrete, spectrum.
