Load-side Power Control System connection complying with 705.13 [2022 CEC] Project Scope and Compliance Details 4 Compliance Analysis for SOLAR RESIDENTIAL ONLINE Application Permit Application Requirements ✓ Qualified Personnel The project’s contractor must possess an active business license from the City of San Juan Capistrano and an active CSLB license with at least one of the following classifications: B - General Building Contractor C-46 - Solar Contractor C-10 - Electrical Contractor Reference: CEC 690.4 ✓ Eligible projects To qualify for an online solar permit, a project must involve installation of a PV module or an ESS unit. ✓ AC Nameplate Rating of PV Modules As per Senate Bill 379, residential rooftop PV installations that are no larger than 38.4 KW AC nameplate rating may qualify for an express permit. Reference: Senate Bill 379 ✓ Specification Sheets and Installation Manuals Specification sheets and installation manuals (if available) for all major PV system components. These uploads must include specifications for all of the following: PV modules Mounting systems ESS components Inverters Project Scope and Compliance Details 5 Reference: CEC 690.4 Structural PV Array Mounting Requirements ✓ Weight of the PV System The 4 psf average self-weight limit of a PV array, including its support components, is easily met by virtually all PV systems. Even glass-on-glass modules, including bifacial modules, fit within this distributed weight limit. This limit is similar to the weight of roof overlays, which were usually allowed automatically in 1990s and earlier Building Codes. ✓ UL-2703 Fire Rating of the PV system The PV system meets the minimum required fire class rating of the roof. Reference: CBC 1505.9 and R 902.4 ✓ Attachment Points of the Mounting System By staying within the 4 psf distributed weight for the array, the point- loading of roof framing members is negligible. When the design snow load is 10 psf or less, staggering of attachments is not necessary since the combined load of the snow and the array is still within the point loading limits of the roof members. ✓ Maximum Spacing between Adjacent Attachment Points The standard distance between attachment points for most locations in the United States is 48 inches. This allows for snow loads up to 60 psf and wind loads as high as 150 mph. For low snow load (10 psf or less) and low wind load (120 mph or less) areas, an attachment distance of 72 inches is permitted without causing excessive loading of roof framing members. Also, these rules are contingent on the distributed weight of the array being no greater than 4 psf. ✓ Maximum Distance off the Roof Roof installations of PV arrays that are not parallel (or nearly parallel) to the roof structure present unique wind and snow loading issues that may need Project Scope and Compliance Details 6 further review by a design professional. Most residential rooftop PV arrays are mounted between 4 inches and 6 inches off the surface of the roof and are parallel, or nearly parallel to the roof surface. A system on a flat roof will be mounted at a slight angle in most cases to prevent pooling of water on the surface of the solar panels. For parallel-to-roof arrays, the distance between the roof surface and underside of module needs to be limited to 10 inches to control wind uplift pressures and take advantage of the “Kopp factor”. Wind tunnel research (Stenabaugh et al, 2014) shows that this reduction factor is 0.80 or less for arrays up to 10 inches off the roof. ✓ Mechanical Load Rating This check is to ensure that the mechanical loading of the structural rails and attachments are being applied consistently with the manufacturer’s instructions and any listing requirements. The PV modules are listed to UL 1703 or UL 61730 and the manufacturer’s instructions dictate how the module is to be supported and held in place for various mounting methods. The mounting system may or may not be listed to UL 2703 for mechanical load rating. If the UL 2703 mechanical load rating is required by the manufacturer, then the installation must comply with any limitation that this load rating requires. ✓ Wood Shake Roofs PV installations on wood shake roofs are not eligible for an express solar permit. ✓ Roof is structurally sound Rafters that fail the above criteria should not be used to support solar arrays unless they are first strengthened. Excessive roof sag can indicate an originally under-designed roof, or subsequent deterioration of a correctly designed roof. Roof sag, measured in inches, is not to exceed span, measured in feet, divided by 20. This corresponds to a dead load deflection of span L/240. Per IBC, dead plus live load deflections are not to exceed L/180, and if dead load is 10 psf and live load is in the range of 12 to 20 psf, the expected original dead load design deflection is of the order of one third to one half of L/180, that is, L/360 to L/540. Hence a larger dead load deflection of L/240 could indicate problems, warranting further Project Scope and Compliance Details 7 investigation. ESS Electrical Code Installation Requirements ✓ UL 9540 listed ESS UL 9540 is an umbrella standard in that it includes several standards as prerequisites to fulfill the requirements in UL 9540. An ESS is defined as, “Equipment that receives energy and then provides a means to store that energy in some form for later use in order to supply electrical energy when needed”. The most common type of UL 9540 ESS utilizes a lithium-ion battery to store the energy. That lithium-ion battery must be listed to UL 1973, Standard for Stationary and Locomotive Batteries. In addition to the certification for the batteries, the inverters must be certified to UL 1741, Standard for Inverters, Converters, and Controllers for use in Distributed Energy Systems. This is the same standard used for PV utility-interactive inverters that must be specifically listed and labeled for this application [CEC 690.4(B)]. Without this specific identification process for ESS, an unacceptable amount of review would be necessary to approve the equipment used in these systems. ESS that pass UL 9540 meet the basic requirement in the CRC and the CEC for an ESS. Reference: R 328.2 ✓ Installation of ESS Units ESS units must be installed according to manufacturer's installation instructions. Reference: R 328.3 ESS Residential Code Installation Requirements ✓ Limitation on Size of Individual ESS Units This requirement limits the size of an individual ESS unit to 20 kWh. One reason for this basic limitation is to put an upper bound on the amount of energy that can be stored in one enclosure. Individual enclosures are Project Scope and Compliance Details 8 limited to 20 kWh which is consistent with the language of the 2022 CRC. Reference: R 328.5 ✓ Separation of ESS Units The basic code requirement is for ESS units to be located 36 inches apart. For instance, two separate 20 kWh energy storage units could be installed on either side of an inverter that was processing the DC power from these storage units. If no additional large-scale fire testing is provided, these units could be installed as close to the inverter as permitted by the inverter’s instructions and no closer than 36 inches apart from each other. However, if large-scale fire testing showed that the units could be safely installed 12 inches apart, it would be permissible to install both units next to one another on one side of the inverter. ✓ Size and Location of ESS Units ESS shall be installed only in the following location: Detached garages and detached accessory structures. Attached garages separated from the dwelling unit living space in accordance with Section R302.6. Outdoors or on the exterior side of exterior walls located not less than 3 feet (914 mm) from doors and windows directly entering the dwelling unit. Enclosed utility closets, basements, storage or utility spaces within dwelling units with finished or noncombustible walls and ceilings. Walls and ceilings of unfinished wood-framed construction shall be provided with not less than 5/8-inch (15.9 mm) Type X gypsum wallboard. The aggregate rating of the ESS shall not exceed: 40 kWh within utility closets, basements and storage or utility spaces. 80 kWh in attached or detached garages and detached accessory structures. Project Scope and Compliance Details 9 80 kWh on exterior walls. 80 kWh outdoors on the ground. Reference: R 302.6 ✓ Fire Detection Rooms and areas within dwellings units, basements, and attached garages in which ESS are installed shall be protected by smoke alarms in accordance with Section R314. A heat detector listed and interconnected to the smoke alarms shall be installed in locations within dwelling units and attached garages where smoke alarms cannot be installed based on their listing. Reference: R 328.7, R 314, and R 315 PV System Electrical Code Installation Requirements ✓ Grounding and bonding of array mounting system This requirement is to simplify the process of ensuring that the exposed metal of a PV array is well-grounded. UL 2703 has numerous mounting system products on the market that are compatible with many of the PV modules on the market. One key aspect of these listings is that UL2703 certification for a particular mounting system is specific for the PV modules to which it has been evaluated. Generally, the specific type or family of PV module from a specific manufacturer is provided with the installation instructions to show to which PV module products the mounting system has been evaluated. Alternatively, it is possible to install a PV array mounting system that is not fully listed to UL 2703. In this case, each separate exposed metal part would need to have a UL 2703 listed bonding device attached to it for it to be bonded to adjacent metal parts 690.43 [2022 CEC] or a UL 2703 listed bonding device to connect the metal to the EGC. The only exposed metal parts not specifically required to be grounded are the roof attachments that attach the mounting system to the roof. These roof attachments and flashings are not likely to be energized and are often not exposed. The roof attachments are treated in a similar way that other mechanical fittings are Project Scope and Compliance Details 10 treated in the CEC. The definition in Article 100 of fitting in the CEC is as follows: “Fitting. An accessory such as a locknut, bushing, or other part of a wiring system that is intended primarily to perform a mechanical rather than an electrical function.” Reference: CEC 690.43 ✓ Maximum Number of Series Strings per Inverter This requirement is to limit the number of circuits to those configurations that are common for current residential PV systems. Most string inverters today have two, three, or four separate DC inputs. By limiting the number of strings for each input to one or two, no string fusing is necessary. This greatly simplifies the installation process and keeps it consistent with current practice. By limiting the overall input to the inverter to no more than four series strings, this ensures that the conduit connected to an inverter will have no more than 8 current-carrying conductors, upon which the conductor sizing in this guide is based. If 10 - 20 current-carrying conductors are in the exposed conduit, then the conduit fill correction factor is 0.5, requiring 10 AWG conductors for PV source circuit wiring in the raceway. ✓ Field Installed PV Array Wiring This requirement is to simplify PV array wiring. Residential PV system wiring can be reduced to two main categories: (a) exposed string wiring is 12 AWG PV Wire [CEC 690.31(C)(1)]; and, (b) PV source circuit wiring is 12 AWG THWN-2, XHHW-2, or RHW-2. These simple rules work for any PV system with four source circuits or less using PV modules with a rated short circuit current of no greater than 12.8 amps. Since the highest ISC for most PV modules commonly available are less than 12.8 amps, 12 AWG conductors will work for these modules regardless of location in the U.S. as long as there are no more than 9 current carrying conductors in the conduit and the conduit is at least 7/8 inches above the roof surface. For those PV modules with an ISC above 12.8 amps, 10 AWG conductors must be used. Project Scope and Compliance Details 11 Reference: CEC 690.31(c) and CEC 310.15(b)(3)(c) ✓ Equipment is rated for the maximum DC voltage applied. This requirement addresses the need to check to make sure that all equipment that is connected together on the DC side of a PV system is properly configured to prevent equipment from having the DC voltage limits exceeded. Reference: CEC 690.7 ✓ Requirements for Controlled Conductors The 2022 CEC requires that PV system conductors on buildings be controlled to a safer condition when a rapid shutdown switch is operated. The controlled conductors outside 1 foot from the array must be shutdown to below 30 volts within 30 seconds and PV array wiring within the array be controlled to a safer condition when in rapid shutdown mode. Conductors in the array can meet the requirement by segmenting to 80 volt sections within 30 seconds or meet either of the other two requirements in 690.12(B)(2). As of 2021, a new array listing process is available called PV Hazard Control (UL 3741). This new process allows array systems to be evaluated and meet the requirements with the PV array as outlined in 690.12(B)(2)(1) and 690.12(B)(2)(a) [2022 CEC]. Reference: CEC 690.12 ✓ Disconnecting Means The 2022 CEC requires that the PV system disconnecting means separates the PV system from all other systems in a building. Details in CEC 690.13(E) list the characteristics of a PV disconnect. Most commonly a PV system disconnecting means is a switch or circuit breaker. This switch or circuit breaker is marked “PV System Disconnect”, and must be installed in a readily accessible location CEC 690.13(A). Reference: CEC 690.13(a) ✓ The PV array and inverters are correctly configured for safe operation Project Scope and Compliance Details 12 This requirement addresses the need to ensure that: Sufficient number of inverter strings, microinverters, or optimizers are available for the installed PV modules. The maximum number of PV modules that can be connected to a string inverter equals the number of inverter strings times the maxmimum number of modules per string. The maximum number of PV modules that can be connected to a microinverters equals the number of microinverters times the maximum number of modules per microinverter. The maximum number of PV modules that can be connected to optimizers equals the number of optimizers. Sufficient number of microinverter circuits are configured as needed. PV and ESS Electrical Code Interconnection Requirements ✓ Inverter Installation The inverter installation should meet the requirements of Article 705.

Range 10,000 VA, Water heater 4,000 VA, Clothes dryer 4,000 VA, Dishwasher 1,500 VA Step 4: Add all appliance loads together: 5,100+ 4,500 + 10,000 + 4,000 + 4,000 + 1,500 = 29,100 VA Step 5: Subtract 10,000 VA from the total VA (this will be added back in later) 29,100 – 10,000 = 19,100 VA Step 6: Multiply the remainder (19,100 VA) times 40%. 19,100 X .40 = 7,640 VA Step 7: Add the 10,000 VA value from step 5 and the 7,640 VA from step 6 together to find the general load. 10,000 + 7,640 = 17,640 VA Step 8: Compare the heating load to the AC load and take the larger of the two loads AC load at 100% = 29 amps X 240 volts = 6,960 VA, Heat load at 65% = 15,000 VA X .65 = 9,750 VA (largest load) Step 9: Add the general load to the largest of the AC or heating load. General load (17,640 VA) + Heating load (9,750 VA) = Total load (27,390 VA) Step 10: Divide the total load in VA by the voltage 27,390 / 240 = 114 amps (114 amps would equal minimum panel capacity) DF 02/14/24 Symbium Project Id: project_9aa39aed-124b-4060-8b5d-190a0207b774 Uploaded on October 25, 2024, 10:28 AM PDT
