Why Install Photovoltaic Solar Panels?

Since the revisions to Part L of the Building Regulations in March 2014 there has been

a need for a greater contribution from renewable sources of energy for domestic and

commercial constructions. One way to comply with the updated regulations is by in-

stalling Photovoltaic (PV) Solar Panels.

There are numerous benets to installing PV Solar Panels

• PV panels provide clean, green energy. During electricity generation with PV pan-

els there is no harmful greenhouse gas emissions thus solar PV is environmentally

friendly.

• Solar energy is energy supplied by nature – it is thus free and abundant!

• Solar energy can be made available almost anywhere there is sunlight

• Photovoltaic panels, through photoelectric phenomenon, produce electricity in a

direct electricity generation way.

• Operating and maintenance costs for PV panels are considered to be low, almost

negligible, compared to costs of other renewable energy systems.

• PV panels have no mechanically moving parts, except in cases of sun-tracking

mechanical bases; consequently they have far less breakages or require less main-

tenance than other renewable energy systems (e.g. wind turbines).

• PV panels are totally silent, producing no noise at all; consequently, they are a per-

fect solution for urban areas and for residential applications.

Contribution to Running Costs

The table below gives typical consumptions of standard electrical devices. Even when

electrical devices are turned o they may still be consuming power. Photovoltaic Solar

Panels can contribute towards the operation of these products with the contribution

given being determined by the amount of panels installed.

Customers may start with as little as one PS260AC Module and then increase their system

wattage as budget, time, and space permit. As each Photovoltaic AC module produces grid

compliant AC current, the modules serve as building blocks with no matching or string sizing

required.

The integrated Enphase Microinverter instantly converts DC electricity into ready to use AC

power. If an Enphase Envoy is installed, the intelligent Microinverter also sends vital health

and performance information to the Enphase communications gateway.

Advantages

This next generation design eliminates the need for expensive DC wiring components

and centralized power inverters. Also, the Photovoltaic AC Module dramatically re-

duces the complex design and installation process associated with a traditional DC

solar power system.

AC Advantages

• High eciency solar module integrated with an Enphase Microinverter, the world’s

most ecient AC system solution

• Higher Eciencies than String Inverter systems

• Optimized for higher outputs in low light conditions

• Modules are individually optimized

• Eliminates module mismatch losses

• Any shading will aect only the shaded panel, not the entire system

• Easier to Design and Install

• Installation labour reduced, no DC switches, GFCI, etc. required

• Fast, inexpensive mounting - delivered ready for connection

• Pre manufactured cables

• Greater Productivity with more reliability

• AC wiring systems are more ecient at transporting electricity as they do not suer

typical electrical losses that are common in all DC wiring circuits.

• More uptime means more kW-h generated

• Installers need not match PV output characteristics before installation

• Better Performance

• Individual PV breakages (e.g. hail) do not stop system power output

• No system mismatch losses

• Any shading will aect only the shaded panel, not the entire system

• Optional communication hub monitors every module independently

• Peak eciency 96.3%, CEC eciency 96%

• No single point of failure will disable the system

• AC Modules are sealed. No cooling vents mean that the units always stay clean

and dry inside

• Convection cooled with no moving parts

• Safer – no DC-side wiring (eliminates dangerous high voltage DC and all DC wiring

loss)

• Reduced inspection code issues

Safety Instructions

Locating the Unit

General Safety

• The installation of a photovoltaic system requires specialized skills and knowledge

and must only be carried out by licensed/qualied persons.

• Installers should assume all risks of injury and do everything to avoid potential

damages and risks that might occur during installation, including but not limited to,

the risks of electric shock.

• Joule Pulsa modules do not need special cables for connection. All of the modules

have permanent junction boxes, cables and connectors.

• Do not use mirrors or magniers to concentrate sunlight onto the modules.

• The modules generate DC electrical energy from sunlight. They are designed for

outdoor use and can be mounted onto frames on rooftops or in the ground etc.

• Do not paint the module or attach anything on to the back of the module.

• Do not attempt to disassemble the modules, and do not remove any attached

nameplates or components from the modules.

Handling safety

• When handling the module insulated gloves must be worn.

• Inappropriate transportation and installation may break the module.

• Do not lift or move the module by holding the junction box or cable.

• Do not place anything on the module or press on the module surface.

• Do not drop the module or allow objects to fall on the module.

• Do not expose the back of the module to direct sunlight.

• Do not wear metal ornaments while handling the module.

• Do not install or handle modules in wet or strong windy conditions.

Installation safety

• Local, regional and state laws and regulations must be adhered to while installing a

photovoltaic system. For example, any necessary licenses must be obtained prior

to the installation commencing. Regulations around vehicles and ships must also

be observed during the installation.

• Observe all safety rules for the other system components, including the cables,

connectors, charging controllers, inverter and storage battery etc.

• Do not place the modules near a location where ammable gases are either gener-

ated or collected.

• Insulated gloves must be worn during the installation.

• Do not wear metal ornaments during the installation.

• Do not drill holes in the frame.

PULSA PV

installation manual

• Under normal conditions, a module is likely to produce more current and/or voltage

than reported under Standard Test Conditions (STC). Accordingly, the values of ISC

and VOC marked on the module nameplate should be multiplied by a factor when

determining the component voltage ratings, conductor current ratings, fuse sizes,

and the size of controllers connected to the photovoltaic system. The exact factor

value should be suggested by a licensed/qualied person.

• The connecting ends with electricity may cause re, spark or lethal shocks even

when the modules are not connected.

• Electricity can be generated when the modules are exposed to sunlight, even if

they are not connected. It is dangerous to touch 30V DC or higher, so never open

the electrical connectors or unplug the electrical connectors while the circuit is

under load, and do not touch the end with electricity during installations, when the

modules are exposed to sunlight.

• Children should be kept away from the photovoltaic system.

• In order to prevent current and voltage generation during installation an opaque

board can be used to cover the modules.

• Only use licensed/qualied insulated tools.

• The frame of the modules must be grounded according to local, regional and state

safety and electrical standards. A recommended connector or equivalent must be

used for the grounding cable. The grounding cable must be appropriately fastened

to the module frame.

• Only Balance of System (BOS) in conformity to local, regional, state safety electricity

standards and photovoltaic system such as connectors, cables and frames can be

used, avoiding aect on the module performance and/or damage it.

Fire Safety

• Consult your local authority for guidelines and requirements for building or struc-

tural re safety.

• Roof constructions and installations may aect the re safety of a building; an im-

proper installation may create a hazard in the event of a re.

• Use components such as ground fault circuit breakers and fuses as required by the

local authorities.

• Do not use the modules near a location where ammable gases are either gener-

ated or collected.

• The modules have been rated Fire Class C, and are suitable for mounting onto a

Class A roof.

Installation

Select the appropriate installation method as per the installation diagram. The module

clamps should not come into contact with the front glass and must not deform the

module frame. Avoid any shadowing eects from the module clamps.

The module frame cannot be modied under any circumstances. Regardless of the

orientation chosen, at least 4 clamps must be used on each module. For portrait ori-

entation, 2 clamps should be attached to the long sides of the module and for land-

scape orientation 2 clamps should be attached to the short sides of the module.

Depending on the local wind and snow loads, additional clamps may be required. The

applied torque should be about 8Nm.

The modules should be completely free of shade at all times.

Do not place the modules near a location where ammable gases are either generated

or collected.

Mounting System

The system for the xation of modules onto the cross beam rails allows for optimum

security and short mounting times giving the following benets:

• Quick and convenient mounting

• Secure xation with qualitity steel thread

• Application of standard components

Mechanical Installation

Locating the Unit

Roof xing bolts are drilled down through the slate or tile covering the roof. The rub-

ber gasket on the bolt keeps the penetration point in the roof weather proofed. A UV-

resistant EPDM gasket with sealing cone and support collar is counter screwed with

a third mounting nut and safely seals the roof. The roof xing bolt bolt is connected

to the prole by use of a stainless steel clamp of which one side which slides into the

square side of the horizontal prole. The bolt head slides through the prole to the

desired location where the second side of the clamp locks the prole into position.

Mechanical Installation

PULSA PV

installation manual

Locating the Inverter

• With the rail in position the Microinverters are then tted.

• Each Joule Pulsa panel requires its own Microinverter and the Microinverters should

be tted to the right hand side of the connection cables that are xed to the Pulsa

panel.

• The supplied M8 square nut is positioned in the prole using the plastic positioner

supplied.

• The Microinverter is xed to the rail using the M8 bolt.

• Use one inverter per module, one bolt per iverter

Installing Branch Connectors

In addition to the Enphase Microinverters, PV modules, mounting rail, and associated

hardware, you will need the following items.

Enphase equipment:

• Enphase Engage Cable. See “Selecting Engage Cable Type” on page 5 for options.

• Sealing caps, as needed (for any unused drops on the Engage Cable)

• Terminators, as needed (one needed at the end of each AC branch circuit)

• Enphase disconnect tool

Other items:

• Outdoor-rated, weather-proof AC junction box(es)

• Gland or strain relief tting (one per AC junction box)

• Earthing (bonding) conductor

• Torque wrench, sockets, spanners for mounting hardware

• Adjustable spanner or open ended spanner (for terminators)

Lightning Surge Protection

Lightning protection and resulting voltage surge are protected in accordance with BS

7671 and EN 62305-1. It is assumed that the PV modules are installed in accordance

with related standards and that the Microinverter is a part of a broader lightning pro-

tection system in accordance with BS 7617 and EN 62305-1, -3.

In some areas, the statistical frequency of lightning strikes near a PV installation is

high enough that lightning protection must be installed as part of an Enphase system.

In some areas, a surge protection device might be mandatory following a risk analysis,

according to local regulation, BS 7671, or NF C 15-100 (art. 443) & NF C 15-443L.

The rst step to install the Engage Cable is to simply roll out the desired length and cut

it to size. One end is wired directly into the junction box at the head of the branch circuit,

eliminating the need for a separate AC interconnect cable. The other end is sealed from

the environment using an Enphase Branch Terminator. The Microinverter AC cable con-

nectors are then plugged into the regularly-spaced connectors as shown.
