Photovoltaics
(PV)
Inverters
Transformers & Collector Systems
Photovoltaics is a technology used to convert sunlight to electricity. Solar PV panels will be used and designed to achieve optimal energy production on the Langdon Mills Solar project. A number of solar cells electrically connected to each other and mounted in a support structure or frame is called a photovoltaic module. Multiple modules can be wired together to form an array. Photovoltaic modules and arrays produce direct-current (DC) electricity.
Inverters convert the direct current (DC) electricity from the solar panel into alternating current (AC) electricity, so it can be added to the utility grid system.
The electricity generated will be collected on-site using underground cables to the project substation. The project substation will aggregate and feed the electricity to the grid, and includes a transformer that converts – or “steps up” – the electricity to the same voltage carried by the grid transmission lines.
Agriculture
Wisconsin farmers produce world-class products. As stewards of the land, they understand the need to balance productivity and environmental protection. Langdon Mills Solar will be built primarily on agricultural land, and while the product produced is not traditionally agricultural, it generates a necessary, renewable product, and continues the tradition of Wisconsin’s agricultural leadership. Clean solar energy is produced without air or water pollution and provides a revenue stream for farmers, their families, and the local community. At the end of the project’s economic life, the land will be once again available for traditional agriculture.
Glare
Solar panel glare occasionally occurs when an observer sees a direct reflection of the sun caused by a reflection from the surface of a solar panel. As part of its permitting process, Langdon Mills Solar will conduct a glare analysis of the project to verify that solar panel glare will not impact nearby residents, businesses, or transportation.
Solar Noise Impact Assessment
Noise at a solar facility is minimal and limited to the daytime, and comes from inverters, tracking motors, and transformers.
Langdon Mills Solar’s application for state approval of the project requires that a noise study be conducted, with measurements taken at a variety of locations around the project site. The project will operate in compliance with all applicable state noise requirements.
