I will do dc ac cable sizing, string sizing and solar calculations
About this Gig
Do not risk your solar installation on guesswork. Incorrect wiring leads to severe voltage drop, energy loss, failed AHJ inspections, and catastrophic equipment failure. You need precise solar calculations engineered to strict NEC and IEC electrical standards.
As a professional Solar Engineer, I provide comprehensive technical verification for your PV system. Whether you are an EPC, solar contractor, or DIY installer, I deliver accurate DC AC cable sizing, conduit fill analysis, and string sizing to ensure your system operates at peak efficiency and maximum safety.
Your Technical Engineering Package Includes: Precise DC/AC cable sizing for minimal voltage drop (<2%) Optimal string sizing for inverter matching (preventing overvoltage/clipping) Breaker, fuse, and disconnect rating calculations Conduit fill and derating factor analysis Battery bank sizing and load calculations
Stop relying on generic online calculators. Protect your investment and guarantee compliance with professional solar calculations.

FAQ
Q: Why do I need professional DC AC cable sizing for my solar project?
A: Incorrect wiring causes voltage drop, which drastically reduces your PV system's yield and can cause dangerous overheating. My precise DC AC cable sizing ensures your installation meets strict NEC safety codes, maximizes power output, and easily passes your city's AHJ inspection.
Q: What does string sizing mean and why is it critically important?
A: String sizing determines exactly how many solar panels can be connected in series safely. If strings are too long, extreme cold weather will cause overvoltage and destroy your inverter. I perform exact solar calculations to perfectly match your specific hardware and local climate.
