At Clean Power Guide, our editorial mission is to publish technically careful, mathematically transparent, and safety-conscious renewable energy guides. Our standards focus on traceable sourcing, commercial independence, explicit assumptions, and prompt correction of material errors.
1. Primary Engineering Sourcing
We do not base our guides on second-hand marketing claims, forum rumors, or manufacturer sales brochures. Every substantive technical article must be rooted in reputable primary sources:
- Official Electrical Codes: National Electrical Code (NFPA 70 / NEC), Canadian Electrical Code (CEC), and international IEC electrical installation standards.
- Safety Testing Standards: Underwriters Laboratories (UL 9540, UL 1741, UL 1973) and IEEE power engineering publications.
- Peer-Reviewed Research: Studies and empirical solar datasets published by the National Renewable Energy Laboratory (NREL), U.S. Department of Energy (DOE), and academic electrochemical journals.
- Manufacturer Engineering Datasheets: Verified component schematics, continuous ampacity tables, and temperature coefficient ratings.
2. Commercial Independence & Editorial Firewall
Our editorial decisions are made entirely independently of commercial partnerships, advertising agreements, or affiliate relationships:
- We do not accept paid product placements, sponsored reviews, or paid guest contributions.
- Inclusion of a product or brand in a system blueprint is dictated strictly by technical suitability, verified safety certifications, and engineering merit.
- Affiliate links never dictate our rankings or evaluations. If a component is deemed dangerous, fragile, or non-compliant with NEC standards, we say so plainly regardless of commercial relationships.
3. Zero Tolerance for Fabricated Testing
The internet is saturated with synthetic reviews claiming "hands-on testing" with fabricated bench results. At Clean Power Guide:
- We never fabricate oscilloscope waveforms, laboratory thermal imaging, or fake battery cycle test logs.
- Where an article presents mathematical equations or circuit simulations, they are explicitly identified as theoretical engineering models.
- Where physical testing occurs, the exact measurement methodology, test equipment, and environmental conditions are fully documented.
4. Technical Review & Errata
Technical guides are checked against the sources cited in each article and reviewed for calculation consistency before publication. Learn more about our editorial team and methodology. Code requirements vary by jurisdiction and installation, so readers should verify the current locally adopted code and equipment instructions. Material corrections are recorded in our public Corrections Log.
