Questions & Answers

As answered by people managing PowerLab and CodeCrafters.

What makes your product unique?

PowerLab's answer

PowerLab replaces closed, proprietary black-box estimation tools with fully transparent, deterministic mathematical engines. Every calculation factors in real physical anomalies, such as Peukert electrochemical capacity loss in battery storage, cold-temperature open-circuit voltage expansion in photovoltaic strings, and locked rotor amperage surges during motor starts. The entire system runs client-side with zero subscriptions, paywalls, tracking, or required accounts.

Why should a person choose your product over its competitors?

PowerLab's answer

Traditional renewable energy modeling tools like PVsyst, HelioScope, and Aurora Solar lock critical sizing calculations behind expensive subscriptions and obscure their underlying equations. PowerLab provides fully auditable formulations aligned directly with NFPA 70 / NEC 2023, IEEE 1547-2018, and NREL SAM methodologies. Users get instant, reproducible calculations with complete transparency into every formula, derating coefficient, and assumption used.

How would you describe the primary audience of your product?

PowerLab's answer

PowerLab is built for solar photovoltaic designers, electrical engineers, clean energy researchers, vocational renewable energy apprentices, and independent off-grid system builders who require reliable, standards-compliant sizing calculations without commercial friction.

What's the story behind your product?

PowerLab's answer

PowerLab was founded to solve a fundamental problem in clean energy engineering: the lack of open, transparent, and reproducible modeling tools for distributed systems. Sizing errors like ignoring Peukert capacity loss or inverter motor surge regularly cause real-world system failures. PowerLab was engineered to provide an accessible, open-access laboratory where anyone can verify clean energy calculations against established physical and electrical standards.

Which are the primary technologies used for building your product?

PowerLab's answer

PowerLab is engineered using modern web and computational technologies: - Pure deterministic TypeScript calculation engines - Next.js App Router and React for responsive user interfaces - Vanilla CSS and design tokens for high-performance mobile accessibility - Client-side browser storage for local scenario preservation - NREL PVWatts V8 API integration for authoritative solar insolation baselines

Who are some of the biggest customers of your product?

PowerLab's answer

  • Academic Engineering Laboratories & University STEM Departments
  • Vocational Solar & Electrical Apprentice Training Programs
  • Independent Electrical Contractors & Clean Energy System Integrators
  • Distributed Battery Energy Storage (BESS) Designers
  • Off-Grid Solar & Mobile Power Planning Engineers
