Renewable Energy Case Studies

Solar PV systems, wind installations, and battery storage projects

Renewable energy systems, particularly solar PV installations, require careful DC voltage drop optimization to maximize energy harvest. Every percentage of voltage drop represents lost energy production and reduced project ROI. These case studies demonstrate string sizing optimization, combiner design, and DC collection system engineering for utility-scale and commercial solar projects.

Challenge

Large solar farm with strings up to 500 feet from combiners. Need to balance wire cost against energy losses from voltage drop.

Solution

Developed economic optimization model comparing wire cost to lifetime energy losses. Selected 8 AWG for near strings, 6 AWG for far strings.

Result

Optimized balance of 2.1% average DC collection losses with 15% reduction in copper costs versus uniform sizing.
