Certifying photovoltaic components and systems is important in helping to ensure the successful application of the technology. Using the experience in photovoltaic research, development, design, testing and applications, CMR Integrators reviews each PV system design for compliance with the National Electrical Code and the appropriate use of accepted design practices.

CMR Solar Energy Integrators meets the standards to protect the public interest and advances the use of renewable technologies.


The objectives are to:

Basic Principles to Design PV System

  • Select a packaged system that meets the owner's needs. Customer criteria for a system may include reduction in monthly electricity bill, environmental benefits, desire for backup power, initial budget constraints, etc. Size and orient the PV array to provide the expected electrical power and energy.
  • Ensure the roof area or other installation site is capable of handling the desired system size.
  • Specify sunlight and weather resistant materials for all outdoor equipment.
  • Locate the array to minimize shading from foliage, vent pipes, and adjacent structures.

  • Design the system in compliance with all applicable building and electrical codes.
  • Design the system with a minimum of electrical losses due to wiring, fuses, switches, and inverters.
  • Properly house and manage the battery system, should batteries be required.
  • Ensure the design meets local utility interconnection requirements. //Top..

Spin Your Electric Meter Backwards!

Solar Photo-voltaic (PV) technology is the way of the future, for generating and supplying electric power for homes and businesses in the US and across the world.

Despite the great potential of Solar PV, current cost and efficiency of solar panels makes them a green, yet expensive alternative to conventional ways of generating electricity, such as Coal, Gas and Oil fired power plants as well as Nuclear and Hydro electricity.

Main obstacle that is holding the wide-spread of solar PV is the long ROI (return on investment) that in some situations may exceed 10 years. Fortunately, US federal government and local and state governments have a multitude of incentives and rebate programs for solar and other renewable energy projects.

Purpose of this Solar PV system design guide is to help you squeeze the most efficiency out of your solar system, making it collect as much sun light as is available throughout the year. //Top..
