Equipment Certification
Equipment certification is a way for states to standardize the certification process and ensure consumer protection against substandard equipment. States that offer financial incentives to promote the use of renewable energy technologies need a rational basis for determining which systems qualify for state incentives. Equipment certification allows states to have confidence that the equipment is installed properly and that the equipment is of acceptable quality. The certification process usually requires the equipment to meet some set of performance criteria and stipulates that the purchaser apply to the appropriate office for certification.
The application process for equipment certification in the state energy offices or other agencies may vary, especially in solar applications. Some states require that the equipment meet the standards set by a recognized certification agency such as the Solar Rating and Certification Corporation (SRCC). The SRCC is a nationally recognized organization that performs standardized testing on the solar collecting part of a system. Others also require that an individual provide proof of purchase and installation, particularly when claiming a tax credit. Other states require engineering drawings of the system or permits for installation after system certification requirements have been met. Many states require that the equipment carry minimum warranties on materials and installation. Some states require that all equipment be certified before it is sold. For wind turbines, manufacturers are usually required to apply for equipment certification.
Solar
Most states that require solar equipment certification use the requirements set forth by the SRCC. By analyzing the materials used in the system and testing the system as a whole, the SRCC can give the system a performance rating that can be used to compare systems. The SRCC also offers a series of booklets designed to educate consumers about solar equipment systems.
Wind
Few states require wind turbine certification. For small turbines, the American Wind Energy Association (AWEA) issues performance guidelines that can be used by states to evaluate wind equipment. AWEA has been an active participant in the development of national and international standards. Small turbines are suited to on-site applications—everything from powering the on-board electrical needs of sailboats to rooftop mountings for rural homes and schools. Fundamentally, small turbines are used for off-grid applications.
In today's global marketplace, equipment certification becomes an international issue. Consequently, the industry supports international certification standards. Compatibility of U.S. standards with foreign standards ensures that American firms have access to foreign markets.
Arguments for Equipment Certification
- States have a rational method for qualifying systems for tax credits.
- States have a reliable method for setting codes and standards.
- Consumers obtain a standardized measurement of quality and performance to help them compare products and determine the best buy.
- Provides a defense for both the consumer and the solar contractor against unethical competition and false claims.
Arguments against Equipment Certification
- States may not want the administrative burden of implementation and monitoring.
- There may be an additional financial burden to small businesses.
