Solar Glossary

The solar power glossary

C CO2 Abbreviation for carbon dioxide. Harmful substance which is emitted when fossil fuels combust. With a solar power system, more CO2 is saved within a few years than the CO2 emitted while manufacturing the solar modules themselves.
D DC and AC cables Indicates direct current and alternating current cables.
E Environmental management A company's approach to systematically reducing the effect its actions have on the environment. Company strategies should combine economic growth with environmental sustainability. The reduction of harmful emissions, waste avoidance and the use of renewable energies are included in the catalogue of environmental measures implemented. A company's environmental guidelines, environmental auditing and standards such as ISO 14 001 are an integrated part of such an approach.
EPDM Ethylene propylene diene monomer rubber, an exceptionally resistant synthetic material 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 solar glass in modules and to the film on the rear.
F Flasher Exceptionally large flash unit which is used during quality checks on modules.
Flat roof installation Type of installation for solar power modules where the solar modules are fitted to flat roofs using an angled or telescopic structure.
Full integration Consolidation of all upstream and downstream production stages of a product under management of a single company. SolarWorld AG covers the complete value chain, from the raw material, silicon, through to finished modules.
I ISO 9001 International quality management standard which specifies recognised requirements for quality management systems.
ISO 14001 International environment management standard which specifies recognised requirements for environmental management systems.
ISO certification Certification (from Latin 'certe' = certainly, surely and 'facere' = do, make, produce) refers to a process used to prove compliance with specific requirements for management systems (companies). Certificates are issued on a time-limited basis by independent certification bodies such as TÜV, DEKRA and Bureau Veritas and verified independently with regard to standards.
Ingot mould Casting mould into which silicon is melted and then cooled, turning it into a polycrystalline block in the process.
Inverter Converts direct current generated by the solar cells to grid-compatible, alternating current; it also stores operating data and monitors the grid connection.
J Joint venture Cooperation in an economic activity between two or more companies in order to optimise expertise and resources.
M Module A photovoltaic module is an interconnected assembly of solar cells. It is made weatherproof by sealing the assembly with silicon behind glass in an aluminium frame.
Module/cell efficiency A module or a cell's efficiency is defined as performance according to surface area. However, the efficiency rating does not indicate the yields a module or cell may produce.
Monocrystalline Solar silicon is solidified into a uniform, cylinder-shaped crystal as a result of conditions during the crystallisation process.
Monosilane Monosilane is the simplest form of silane (silicon analogues of alkane hydrocarbons). It is used in solar silicon production.
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.
