⚡ Registered Electrical Engineering & Clean Energy Platform

About ProjectSolar & Our Engineering Mission

Bridging transparent electrical engineering standards (PEC Article 6.90 & NEC 690) with accessible, high-precision solar sizing software for homeowners, businesses, and installers.

🎯 Why We Built ProjectSolar

For years, residential and commercial solar buyers in the Philippines and across Southeast Asia faced two common problems: opaque "rule-of-thumb" sales quotes that omitted critical electrical protection hardware, or overly complex enterprise simulation tools locked behind expensive licenses.

ProjectSolar (prosolar.app) was engineered to democratize accurate photovoltaic design. Every calculation on our platform—from PV string open-circuit voltage (Voc) limits and LiFePO4 battery C-rates to copper conductor Voltage Drop Index (VDI) and 125% continuous-duty breaker sizing—is transparent, deterministic, and verifiable.

👷‍♂️ Led by Licensed Electrical Engineers

Our calculation algorithms, Single-Line Diagram (SLD) schematics, and technical guides are developed and maintained under the supervision of a Registered Electrical Engineer (REE) with field experience in rooftop photovoltaic EPC installations, Meralco & Electric Cooperative net-metering applications, and industrial power distribution.

Our engineering workflows adhere strictly to the Philippine Electrical Code (PEC 2017 Part 1, Article 6.90), TESDA Solar PV Installation NC II competency standards, and NFPA 70 / NEC Article 690 guidelines.

🛠️ What Our Platform Provides

ProjectSolar combines four core resources in one open web platform:

  • 14-Formula Solar & Battery Calculator: Real-time kWp sizing, LiFePO4 battery autonomy, wire gauge selection, and 25-year NPV/IRR cash-flow modeling.
  • Visual SLD Schematic Builder: Interactive drag-and-drop canvas that validates MPPT string voltages, breaker ratings, and earthing in real time.
  • Verified Equipment SRP Catalog: Transparent Philippine retail pricing for Tier-1 bifacial panels, hybrid inverters, and protection gear.
  • In-Depth Engineering Guides: Long-form technical documentation on net metering, zero-export, PEC wiring, and battery longevity.
