B Grade Panels Advisory - Important Advisory for All SolarGenerations Customers and Companies

RenewableGenerations  has been made aware of a growing market for new, but blemished solar panels which are not eligible for participation in the SolarGenerations program. Many distributors sell these panels, often listed as “b” grade panels, for a substantial discount.  These panels are manufactured by leading manufacturers and carry similar model numbers to panels listed on the California Energy Commission list that NV Energy uses for incentive eligibility in the SolarGenerations program. Please be advised that panels must have the exact classification code listed on the California Energy Commission list of eligible panels to be eligible for an incentive.

 SolarGenerations - Solar Hot Water

Solar Hot Water Licensing Requirements

Program participants are required to use an eligible contractor with a valid Nevada C-1, C-1 (d), C-1(h), C-37, or C-37(a) contractor’s license to install their solar hot water system.

How to Become an Eligible Contractor

NV Energy's solar hot water incentive program customers are required to use an eligible Nevada contractor to install their solar hot water system. Eligible contractors will assist customers with the incentive program application process, the purchase and installation of the solar hot water system and completing the incentive claim process.

Contractors interested in becoming eligible for the solar hot water incentive program must hold a Nevada State Contractors C-1, C-1 (d), C-1(h), C-37, or C-37(a) license and complete several steps.

Successfully completed a NV Energy sponsored Contractors Eligibility Workshop

The eligible contractors workshop is a one-day class covering all aspects of solar hot water system installation, including; collector systems, OG-300 requirements, site analysis, designing and sizing, component selection, installation techniques and maintenance. NV Energy will also deliver a program training outlining the incentive program details.

Completion of this course by the contractor license Principal and or the Qualified Employee(s) as listed with the Nevada State Contractors Board is mandatory to participate in the NV Energy Solar Hot Water Program. This will satisfy the requirement for the entire company to be eligible as a contractor. Attendance by all other company employees is optional, but is strongly recommended for installers and other personnel involved in the application process.

Upcoming Training Dates:

No training scheduled at this time

The NV Energy workshop does not satisfy the eligibility requirements for the Southwest Gas program. For more information on the Southwest Gas program please call 1-855-743-1603 (toll-free) or visit www.solarwaterheatingrebate.com.

Eligible Equipment Requirements

To be eligible for an incentive in the WindGeneration program, turbines must meet one of the following requirements:

A. Turbines smaller than 200 m2 (swept area) must be certified by one of the following organizations:

B. or, listed by one of the following organizations:

Utility Standards for Net Metering

These utility standards for a Net Metering system are required on each approved and installed system. They include the engineering requirements for the REC meter and utility disconnect. Contractors are required to incorporate these standards in the design.

Net Metering Rider  - North   |  Net Metering Rider  - South

IMPORTANT NOTE - Systems Using Back-Up Batteries

Systems that incorporate back-up batteries must ensure that all output from the renewable system will be recorded by NV Energy meters. We strongly recommend customers using this type of system submit one line diagrams to RenewableGenerations for review prior to installation.

Technical Tips

400 Amps residential services.  These normally have two 200 A circuit breakers; one of these breakers serves a distribution center that is rated at 200 Amps and not 400 amps. The largest PV system that can be connected to the 200 A section is ~ 7.5 kw. Installation of systems larger than 7.5 kW will require modifications to the electrical system.

Voltage imbalance. Install of a single phase inverter on a three phase system may create a voltage imbalance what impacts the customer’s three phase motors. Current imbalance is normally 6 to 20 times larger than voltage imbalance.

Voltage Rise.  Energy flow is always from a higher voltage to a lower voltage, even when the voltage difference is very small.  The inverter operation will create a voltage rise within the customer’s facility. Depending on the exact configuration within the customer’s facility, the effect of the voltage rise may impact operation of customer equipment or cause the inverter to cycle on and off.

Safety Switch. NV Energy policy requires a visible, lockable, readily-accessible disconnecting means (industry-standard safety switch) that is wired so that the movable blades are de-energized in the open position. The exception to NEC Article 404.6 is not applicable because inverters are independent voltage sources.

Supply side taps.  Taps for distributed generation including PV systems are permissible under the National Electric Code. However, any modification to service equipment may compromise the UL listing of the service equipment.  Most residential service equipment has a combination meter, service disconnect (main), and possibly a distribution section. Supply side taps to this equipment will normally compromise the listing of the equipment and is therefore not allowed.   Switchboard and some wall mounted service equipment can successfully be modified to accommodate the supply side tap. However, the equipment manufacturer, the AHJ, or a third party NRTL will have to provide documentation that the equipment is still listed..

Load Side Taps.  The tap rules under the National Electric Code are designed for load and not sources. Addition of sources as a tap configuration may create a dual source bus and the existing load is now a tap configuration and needs to be properly protected. PV systems and other sources have to be connected so that system conductors and all other conductors are properly protected. The NEC specifically requires that the system connect to dedicate circuit breaker or fuse.

Meter Sockets.  Meter Sockets are normally designed to be installed on the supply side of the service disconnecting means and may have a bonded neutral that is part of the listed assembly. Removing the bond compromises the listing.   Meter sockets are to be wired so that energy from the source is connected to the top jaws to measure gross production.
