2 Technologically advanced and consistent in performance, the photovoltaic module that combines quality and simplicity

3 The name Mitsubishi is synonymous with excellence Known the world over, Mitsubishi is a trusted global leader associated with a variety of products and services. Founded in 1921, the company known today as Mitsubishi Electric rose to the forefront of the solar and PV industry in the late 1970 s, a position we still enjoy today. Increasing attention is being paid to the cost and the environmental impact of powering homes in the UK. As a leading manufacturer of PV systems, we constantly strive to meet and exceed the increasing customer demands placed on our industry. The drive to reduce energy consumption and the impact its use has on the environment is crucial and increasingly important to us all. The need to be more energy conscious and environmentally responsible has long driven Mitsubishi Electric to spend millions of pounds and huge amounts of resource on researching and developing the solutions of the future. At the forefront of the very latest technology, we pride ourselves in providing high performance and competitive systems on which you can rely. Responsible manufacturing Mitsubishi Electric boasts an explicit commitment to sustainable business practices such as energy and resource efficiency, minimising ecological impacts and reducing greenhouse gas emissions. All our factories are ISO14001registered, the international standard that ensures that our manufacturing processes ensure optimum environmental performance and tight control on waste. We have also gone further than any accepted minimum standards. Our Global Environmental Vision 2021 provides a goal for a lower emission future that influences all our policy decisions. The UK Green Gateway Initiative takes this vision even further as it looks to install behavioural change in our own operations and our wider sphere of influence with contractors, consultants and end users. It looks to highlight the advantages and opportunities provided, by ensuring all our activity is undertaken with consideration to the environment. We are also proud to be a partner within Sustainable Energy Europe, whose stated aim is to raise awareness of energy use in Europe. 3

4 Saving energy and meeting environmental obligations with Mitsubishi Electric photovoltaic (PV) modules Mitsubishi Electric s photovoltaics (PV) are now available in the UK to help organisations and individuals meet their environmental and energy saving objectives. Since the beginning of the decade high-efficiency Mitsubishi Electric PV modules have been deployed across a huge variety of projects in Asia, the US and continental Europe; whether in small off-grid deployments in remote areas of Indonesia, as part of power purchase agreements in the US agricultural sector, or within utility-scale projects in Germany. Here in the UK, Mitsubishi Electric s photovoltaics are being made available through the Living Environmental Systems (LES) division, alongside our established air-handling and heating products. This ensures the level of service and support that our customers expect, with all the supply chain advantages and product and performance warranties associated with this. Technology Photovoltaic modules utilise light energy - not heat - to generate DC current. This is converted to AC current by an inverter, making it available for use within the building or to export if surplus energy is generated. With no moving parts a PV system runs silently and reliably, with the likely lifetime of the modules being 30 years or more. Typical PV System Layout 4

5 Iida Factory Japan Quality Manufacture Sound provenance is an increasingly important issue as low-grade, low performance modules become more commonplace in this rapidly growing market. Mitsubishi Electric controls quality through vertical integration of the cell and module manufacturing processes at our own facilities in Japan. Nakatsugawa Works produces cells at the Iida factory for assembly into modules at the facility in Kyoto. Nakatsugawa Works is an ISO certified plant, having obtained both ISO 9001 Quality Management System and ISO Environmental Management System certification. Of course, Nakatsugawa Works has also been audited as part of the Microgeneration Certification Scheme (MCS) accreditation. Module Assembly Facility Kyoto, Japan 5

6 UK Feed-in Tariff for Low Carbon Electricity In February 2010 the Government confirmed the rates available under the Feed-in Tariff for low carbon electricity. Feed-in Tariff policies have been very successful in other European countries at encouraging the installation of PV systems. Feed-in Tariffs offer a generous ongoing income to system owners, based on the output of the system. This additional income reduces payback times and creates opportunities for system owners to profit from the system. In the UK, the Feed-in Tariff mandates payments to owners of PV systems from their electricity supplier. There are two components to the payment; the generation tariff, paid on the total generated and the export tariff, paid on the amount of unused electricity that is exported to the grid. The Feed-in Tariff offers different rates according to the size of the system. These are as follows: System Size Generation Tariff Export Tariff <4kW (Retrofit) <4kW (New Build) 4-10kW kW 100kW - 5MW 41.3p 36.1p 36.1p 31.4p 29.3p 3p 3p 3p 3p 3p 6

7 Mitsubishi Electric s CO2 Strategy A key benefit of photovoltaics is that they displace carbon-heavy electricity, so are particularly effective in helping clients to meet CO2 targets. As such, they are part of a suite of products that includes the Lossnay fresh air heat recovery unit and Ecodan air source heat pumps. When combined, these products are particularly effective at reducing overall CO2 emissions from a building and are being used with increasing frequency in the residential new build sector, where developers are seeking economical ways of meeting their obligations under the Code for Sustainable Homes. Mitsubishi Electric is committed to reducing CO2 emissions, both through the Environmental Vision 2021 statement, which embodies Mitsubishi Electric s long-term environmental management vision and through the Green Gateway Initiative which focuses on the heating and cooling market in the UK. Installation Mitsubishi Electric ensures that when a customer selects our product for their installation we have a Microgeneration Certification Scheme (MCS) certified offering. In order to support our commitment in providing certified products, Mitsubishi Electric strongly recommend our products are installed by MCS certified installers. MCS accreditation ensures that contractors shall have the capability and capacity to undertake the supply, design, installation, set to work, commissioning and handover of solar PV Microgeneration systems and that the contractor operates a satisfactory quality management system. It also ensures that the mechanical elements are properly specified and installed and that weather-tightness is maintained, with wind loads and static loads properly accommodated. For larger projects and those requiring more complex architectural integration, Mitsubishi Electric has relationships with higher-level PV integration companies who have the experience and know-how to manage a project through both the design and installation phases. Subject to qualification of the project, Mitsubishi Electric can offer guidance and facilitation of this process. For installation of Mitsubishi Electric PV Packs it is important that the installer has the skills necessary to work with all the components in the pack and for that reason installers with these capabilities are recognised separately as Accredited PV Pack Installers. 7

9 PV-TD Series PV Modules The PV-TD Series is Mitsubishi Electric s core PV product range in the UK. These are high quality 50 cell polycrystalline modules, with output capacities ranging from 175W to 190W. Standard dimensions and frame profile mean that they are compatible with all mainstream mounting systems and roof types; membrane, standing seam, profiled, tiled etc. Likewise, they can be installed into a vertical façade. An exceptionally rigorous cell selection process ensures consistent voltages across all the modules in an array, thus maximising the system current and the yield that can be expected. This exacting approach is also reflected in the very tight tolerance range of the nominal maximum power output (Pmax) and the fact that the average Pmax per shipment is always higher than the nominal rating. The assembly process also applies the same thorough standards, resulting in modules that exceed mandatory requirements in damp heat and thermal cycle testing. Meanwhile, the PV-TD Series modules have passed static load testing to 5400pa. This clear durability advantage is backed by best in class warranties: 5 year product warranty and a 25year/80% performance warranty. Other features include: g Zero lead content through elimination of solder coating. Silver finish also increases the amount of reflected light available for the cells. g Redesigned bus bar to reduce series resistance. g World s first triple layer junction box, with metal cover, to ensure weather-proofing and non-combustibility. g MC4 connectors with lock mechanism for simpler and more reliable installation work. The modules meet IEC and EN They carry the CE mark and are accredited under the Microgeneration Certification Scheme (MCS), which ensures eligibility for UK Government sponsored incentives, such as capital grant schemes and special tariffs.

10 Mitsubishi Electric PV Packs Incorporating Mitsubishi Electric TD-Series modules into convenient G83-compliant kits for both on-roof and semi-integrated installations. Includes: Modules Inverter AC Isolator DC Isolator Meter Mounting Kit Mitsubishi Electric PV Packs have been designed for residential properties with pitched roofs. With both semi-integrated and on-roof versions available, these kits are suitable for the vast majority of roofs in the UK, whether new build or retrofit. 10

11 The PV Pack is part of Mitsubishi Electric's whole house strategy that also includes the Ecodan air source heat pump and the Lossnay fresh air heat recovery system. Each of these technologies can be installed on their own, or can be combined to achieve dramatic reductions in energy consumption and CO2 emissions. Under the right conditions, the annual costs and CO2 emissions from heating can be reduced to zero. The PV Packs use MCS accredited hardware so are eligible for Government incentives such as grants and special tariffs, when properly installed by MCS accredited installers. All kits with AC outputs under 16A are compliant with the G83 grid connect standard. Mitsubishi Electric PV Pack Features: Mitsubishi Electric PV-TD185MF5 modules with 25 year performance warranty Market-leading G83-compliant inverters, with remote monitoring option and warranties up to 20 years Pack sizes available in small increments, starting from 1.48kWp Design and commissioning services available from Accredited PV Pack Installers Roof installation training available Full Owners Pack provided 11

12 Mitsubishi Electric PV-TJ Series Larger, higher efficiency modules aimed at large-scale commercial projects Features: 60 cell format: Higher capacity per module reduces install and handling costs. 4 bus-bar cell: Lower resistance, so higher efficiency. Narrower tab strings to maximise area exposed to light. New I-frame design for greater strength and easier handling. Protection bar for greater rigidity and durability (also features on PV-TD series). Quadruple layer junction box (fire retardant mica sheet added to previous 3 layer design). The new PV-TJ Series modules are higher capacity modules designed for larger commercial projects requiring Mitsubishi Electric quality, with lower installation costs. By combining a 60 cell configuration with Mitsubishi Electric s 4 bus-bar cells, the PV-TJ Series modules achieve increases in output capacities of 25% in modules that are just 19% larger than the equivalent PV-TD Series. 12

13 The PV-TJ Series features Mitsubishi Electric s new 4 bus bar 156mm cell. These increase efficiency by reducing the length and thus the internal resistance of the grid electrodes. In order to maintain the resulting efficiency advantage, the tab strings have been narrowed to allow the same surface area to be exposed to light. With six rows of ten of these cells the PV-TJ series has a capacity around 25% greater than that of the PV-TD series. Other new features include a new I-frame design for increased strength and easier handling, a quadruple layer junction box and additional grounding holes. PV-TD Series 2 Bus-Bar Cell PV-TJ Series 4 Bus-Bar Cell Meanwhile, fundamental features are carried over from the PV-TD Series including the 156mm cell size, cell uniformity selection to eliminate hotspots, lead free solder, the protection bar and high power in actual use module selection. Factory-shipment test values actually exceed the nominal output power for each carton. 13

14 Mitsubishi Electric Hatfield Head Office, UK The Mitsubishi Electric Hatfield office has a photovoltaic array consisting of 46 x PV-TD185 polycrystalline silicon modules which are separated into two arrays.
