Contracting and Code Compliance

The best way to inspect and determine the workmanship and value of a solar energy system is onsite and by looking on above and under the solar modules - look under the hood - for damage and defects of a rooftop or ground-mounted solar energy system.


CODE COMPLIANCE AND THE SOLAR INDUSTRY For example, local AHJ Inspections determine Code compliance (Electrcal and the I codes), non local goverment AHJ inspections may include performance, workmanship, industry standard practices, contracts and the Business and Professions (B&P) Code.

2nd-Party Industry Standard Practices & 3rd-Party Inspections

A independent inspection or review of existing or new proposed physical installations to industry standards and best practices - from a licensed certified PV installer perspective: If the system is existing, we will only (1) identify the issues and (2) provide you with an $ estimate cost to fix the issues and NOT contract to fix the system. For example, may be issues with poor workmanship, not following manufacture's instructions and other issues. After our independent inspection, we will not contract correct your issues would be a conflict of interest. We only contract for NEW system installations.

A Story of a Solar Party

Two Parables of Happiness and One Happy Ending. Story #1: Mixed Emotions at a Solar Party A customer was so happy to purchase a brand new solar PV energy system, they invited their colleagues and friends to a solar party. Announcements were printed and mailed. On the day of the party, all the guests went up on the roof to examine the new system and the roof collapsed. This puts a damper on any event. What would you have managed differently in this parable? Both commercial and residential solar systems require project management with complete technical process elaboration. In addition, consider the structual critera for residential rooftop solar energy installations for one- and two- family dwellings.
