Utility Solar Farm DC Collection System
Optimizing DC voltage drop for 50MW utility-scale solar farm.
1.8% total DC collection losses
$180,000 annual energy savings
ROI achieved in 18 months
Exceeded performance guarantees
Challenge
Long DC string runs in high-temperature environment with strict 2% loss budget
Solution
Optimized string sizing with aluminum conductors and strategic inverter placement
Project Overview
A 50MW utility-scale solar installation in the Nevada desert required careful DC collection system design to minimize voltage drop losses in the extreme high-temperature environment.
Technical Challenges
The desert environment presented unique challenges: ambient temperatures exceeding 45°C, long string runs up to 500 meters, and a strict 2% DC loss budget to meet investor performance guarantees.
