A diversity of knowledge, skills, and abilities are required to design, install, and commission PV Systems. The process involves several qualified individuals and organizations, each with an important role in ensuring the safe, reliable, and long-term performance of the PV Power System.
In 1992, the US had 40% of the world installed PV capacity, the largest share held by any country. By 2009, PV installation in the US had grown to more than 38 times the 1992 level but accounted for only 7% of the worlds installed PV capacity. Some other countries have been installing PV Systems at a much faster rate than United States. Currently, the global PV industry is dominated by Japan and Europe, especially Germany.
There are hundreds of PV cell and module manufacturers in the world, located in almost every industrialized country. Electrical equipment manufacturers design, develop, and fabricate the Balance Of System (BOS) components. A BOS component is an electrical or structural component, aside from a major component, that is required to complete a PV System.
BOS components include the conductors, connectors, switchgear, fuses, and hardware that connect, support or interface between the primary devices such as the array, inverter, and battery system.
Installers have an important role in ensuring quality PV installations. Installers should exhibit quality electrical craftsmanship, and because of the unique aspect of the equipment and interfacing of PV technology, they should be qualified specifically for installing PV Systems.
All PV System Installers should meet the following criteria:
1. Complies with applicable buildings and electrical codes and standards.
2. Applies for permits and approvals from local building and utility authorities as required.
3. Knows his or her capabilities and limitations, and seeks outside expertise as required.
4. Selects and sizes systems and equipment to meet performance expectations.
5. Recommends well-engineered, quality components.
6. Ensures equipment is properly labeled and safety hazards are identified.
7. Locates and orients array to maximize performance and accessibility.
8. Mounts array with strong, weather-sealed attachments.
9. Uses accepted utility-interconnection practices and obtains utility approvals as required.
10. Completes work in a timely manner while practicing safe and orderly work habits.
11. Employs safe and accepted methods in the installation and use of PV equipment.
12. Completes inspections, commissioning, and acceptance tests.
13. Provides owner/operator with appropriate documentation, instructions, and training.
14. Provides follow-up service for completed work as required.
An experienced installer also has considerable design knowledge and familiarity with many types of PV Systems and components and can diagnose and troubleshoot even complex systems effectively. Installers are perhaps the most visible members of the PV Industry to the consumers, making it vital that installers be professional and qualified individuals.
