The solar power glossary

C CO2 Abbreviation for carbon dioxide. Polluting compound emitted when fossil fuels are burned. Solar power systems prevent the emission of more CO2 than is produced during the manufacturing process of the solar panels.
D DC and AC cables Cables for direct current and alternating current.
E Environmental management A systematic corporate approach to reducing the impact of its operations on the environment. Corporate strategies should aim to establish a balance of economic growth and environmental sustainability. Measures which can be taken to make a company more environmentally friendly include reducing pollution, preventing waste where possible and using renewable energy sources. A company's environmental policy, environmental auditing and standards such as ISO 14 001 also form part of this approach.
EPDM Ethylene propylene diene monomer rubber, an extremely durable synthetic substance used in the automotive industry. SolarWorld uses EPDM to seal and hold solar modules and laminates in place.
EVA Abbreviation for ethylene vinyl acetate, a synthetic material. EVA film binds cells to the glass in solar panels and to the film on the rear.
F Flasher Very large flash unit used for quality control on modules.
Flat roof installation Method of installing solar modules in which they are secured to flat roofs using an angled or telescopic structure.
Full integration Combination of all upstream and downstream production phases managed by a single company. SolarWorld AG covers the entire value chain, from the raw material, silicon, through to finished modules.
I ISO 9001 International quality management standard which stipulates accepted requirements for quality management systems.
ISO 14001 International environment management standard which stipulates accepted requirements for environmental management systems.
ISO certification Certification (from Latin 'certe' = certain, sure and 'facere' = do, make, produce) is a process used to verify compliance with specific requirements for management systems (companies). Certificates are issued for limited periods by independent certification bodies such as TÜV, DEKRA and Bureau Veritas and verified to independent standards.
Ingot mould Cast mould into which silicon is melted and then cooled, which turns it into a polycrystalline block.
Inverter Converts direct current generated in the solar cells to grid-compatible alternating current; also stores operating data and monitors the grid connection.
J Joint venture Commercial cooperation between two or more companies to make best use of expertise and resources.
M Module A photovoltaic module is an interconnected assembly of solar cells. It is weatherproofed by sealing the assembly with silicon behind glass in an aluminium frame.
Module/cell efficiency A module's or a cell's efficiency is defined as performance according to surface area. However, the efficiency rating is not an indicator of the yield a module or cell may produce.
Monocrystalline Solar silicon is solidified into a uniform, cylindrical crystal due to conditions in the crystallisation process.
Monosilane Monosilane is the simplest form of silane (silicon analogues of alkane hydrocarbons). It is used to produce solar silicon.
Multicrystalline As a result of conditions during the crystallisation process, solar silicon is solidified into a silicon block consisting of several smaller crystallites of varying sizes and orientation.
