Large-Scale Solar Installation in the Charlottesville / Zion Crossroads Area

Cenvar Solar's Charlottesville branch recently completed a large-scale photovoltaic (PV) installation for a homeowner in the Zion Crossroads, VA area. This comprehensive project, paid for in cash, utilized premium REC and Enphase equipment to establish long-term energy independence.

The System Design: High-Performance and High-Volume

The system was precisely engineered to handle the home's substantial energy needs, which can exceed 2,900 kWh per month in the winter, according to their Central Virginia Electric Cooperative (CVEC) utility data.

• System Size: The installation features 35 solar modules to create a 15.75 kW DC system.

• AC Output: The system has an AC rating of 13.300 kW.

• Panels: We installed REC Alpha REC 450AA PURE-RX (450W) Solar Modules. These panels are highly efficient and are backed by REC's 25-year ProTrust Warranty when installed by a certified professional.

• Inverters: The project uses 35 Enphase IQ8X-80-M-US Microinverters, providing panel-level power conversion and meeting rapid shutdown requirements.

The PV array was designed to be mounted across three separate roof planes (Roof 1, Roof 2, and Roof 3), with careful attention paid to setbacks and code compliance.

Engineering for Virginia's Climate and Codes

This project was engineered to meet the stringent local environmental and safety requirements of the region:

• Governing Codes: The design was reviewed under the 2021 USBC and complies with the Virginia Residential Code 2021 and the National Electrical Code, NEC 2020.

• Structural Integrity: The mounting system utilizes UNIRAC Stronghold Butyl direct-to-deck attachments and NXT UMount rail systems. This flashless method provides a robust, dependable seal.

• Climate Specs: The structural attachments are engineered to handle the region's climate specifications, including a Ground Snow Load of 30 PSF and Wind Speed of 115 MPH.

By integrating top-tier solar technology with expert roofing and engineering, Cenvar Solar delivers a superior, long-lasting energy solution for the Charlottesville and Zion Crossroads communities. The homeowner chose a cash purchase for this system, simplifying the long-term cost and maximizing their investment return.
