 Materials

Solar Innova uses the latest materials to manufacture photovoltaic modules:

 

Top Surface

The front of the module contains a translucent sheet made of a transparent thermoplastic polymer extraordinary durability: it has high chemical and mechanical resistance (shear and abrasion) and high stability against temperature changes (supports up to 170° C). It is also combustible but not flammable.

 

It forms the front end of the PV module and protects components housed within the laminate from the weather and mechanical stress.

  • Resists weathering well and especially UV radiation and gamma rays.

  • Low thermal expansion and low moisture absorption.

  • Very good wear resistance.

  • Excellent mechanical strength and rigidity.

  • Excellent dimensional and resistant to many chemical stability.

  • Good electrical insulator.

Top Encapsulant

The sheets of EVA (Ethyl Vinyl Acetate) are used to connect the solar cells through the lamination process with transparent TPT surface. This step provides the "encapsulated" solar module that is responsible for holding together the photovoltaic module and have a decisive bearing on life. The degree of chained EVA sheet after the lamination process is decisive for the quality indicator of the solar module.

 

An EVA sheet must guarantee insulation and protective effect throughout the life of the module. The films of poor quality can cause long-term discoloration, delamination or decomposition and, therefore, strongly impair the performance capability of the module in question. Solar Innova uses only high quality sheet of chains with a degree exceeding 85 %, thus providing long lasting protection of cells.

Bottom Surface

TPT backsheet is composed of a plastic polymer trilayer laminated between two layers of polyester sheet of Tedlar. Provides complete protection and sealed against environmental agents and offers a perfect electrical insulation due to its excellent strength and barrier properties against moisture and UV resistance. It also reduces the operating temperature of the cells.

Junction Box

The primary function is to transmit the energy produced in the module.

 

The junction box installed is made high temperature resistant plastics. The box is sealed and ready for the weather. Has a degree IP-65, which provides the insulation system against moisture, inclement weather, dirt and ultraviolet radiation. Inside are installed bypass diodes.

 

Bypass diodes protect the tensile modulus increased and consequently the so-called hot spot effects.

 

The modules are supplied with box and bypass diodes integrated.

 

In each module there is a single box for both terminals. Polarity must be observed in the connections to the proper functioning of the modules.

 

The junction box can be opened in case of failure, thereby facilitating an eventual replacement of damaged diodes. Covers of junction boxes have an indicative drawing. They open by inserting a screwdriver in the appropriate tab in the direction of the arrow, with light pressure on it to open. To close the lid, simply press it to closure. The lid has a flange attached to the junction box while handling the interior thereof. This flange must not be cut at all.

 

The junction boxes should not suffer any pressure when installing the module on a support structure. No element of it should touch the box.

 

The junction boxes are similar to modules with the same voltage rating. All connection boxes are provided with symmetrical cables of length 900 mm. With a connector positive (+) and a negative connector (-) with a working temperature range between - 40 ~ + 85° C.

Diodes

The shading of a cell can cause a reverse voltage on it. This cell thus consume power generated by the other in series, resulting in undesirable heating of the shaded cell. This effect, called hot spot will be greater the higher the radiation incident on the rest of the smaller cells and cell receiving that due to the shadow. In an extreme case the cell may be broken due to overheating.

 

The use of protective diodes or by-pass reduces the risk of heating of the shaded cells, limiting the current that can flow through them and thus preventing the breakage thereof.

 

All modules with a number of cells greater than or equal to 33 connected in series, manufactured by Solar Innova, are provided with protection diodes that are located at the junction boxes. In modules with fewer cells in series are not required the bypass diodes, as the hot spot effect does not reach the level of risk of rupture of the cells.

 

The replacement of bypass diodes should be performed only by a qualified competent photovoltaic after disconnecting the system module.

 

The replacement of bypass diodes should be performed only by a qualified competent photovoltaic after disconnecting the system module.

Cables

Our modules are fitted with flexible cables, symmetrical in length, with a diameter of copper section of 4 mm, weather resistant and have been specially designed and certified for use in our modules. Have high values ​​of electrical safety and fire resistance. Its insulation to weathering and UV rays ensures longevity of the installation. Furthermore, the wide range of temperature allows its application even in extreme climatic areas, preventing heat aging and therefore allowing a long life in the photovoltaic system. They have a high strength and a very low contact resistance, all designed to obtain minimum voltage drop losses and allows them to continue operating even in unfavorable conditions.

 

All our photovoltaic modules are supplied with cable assemblies in the box with the following features:

  • Length: 900 mm.

  • Operating Temperature Range: - 40 ~ + 90° C.

Connectors

Our PV modules are equipped with connectors and sockets MC-T4 100 % compatible with the connectors and sockets used to connect electrical systems. Only MC-T4 connector or compatible and special solar cables may be used to lengthen the cables connected to the module. These must meet the electrical requirements of the Interconnection design.

 

All our photovoltaic modules are supplied with assembled connectors on cables with the following features:

  • Diameter: Ø 4 mm.

  • Maximum rated current: 30 A.

  • Maximum system voltage: 1000 V.

  • Plugged Protection level: IP-67.

  • Mounting: easy.

  • Locking system: Snap in.

  • Protection Class: II.

  • Operating Temperature Range: - 40 ~ + 90° C.

Sealed

PV modules require the use of silicone sealant high quality for bonding and sealing of junction boxes of photovoltaic modules.

 

Silicone has excellent adhesion to most substrates used in the manufacture of photovoltaic modules and does not lose its flexibility in a wide temperature range so it offers perfect protection against the ingress of water into the laminate.

 

Fabricated with high efficiency. No chemical reactions with EVA material and PVF film protector ensures the chemical stability.

 

The silicone is applied in the grooves of the frame and the edge of the laminate so as to prevent any infiltration of gas or liquid that can erode the module. At the same time, elasticity serves as a protection against possible mechanical impacts during installation or handling.

Labels

This document describes data sheet and nameplate information for non-concentrating photovoltaic modules. The intent is to provide minimum information required to configure a safe and optimal system with photovoltaic modules. In this context, data sheet information is a technical description separate from the photovoltaic module. The nameplate is a sign in durable construction in the photovoltaic module.
