What is BS EN 62093 – BOS components for PV systems about?
BS EN 62093 is an International Standard that establishes requirements for the design qualification of balance-of-system (BOS) components used in terrestrial photovoltaic (PV) systems.
BS EN 62093 is suitable for operation in indoor, conditioned, or unconditioned; or outdoor in general open-air climates as defined in IEC 60721-2-1, protected or unprotected. It is written for dedicated solar components such as batteries, inverters, charge controllers, system diode packages, heat sinks, surge protectors, system junction boxes, maximum power point tracking devices and switch gear, but may be applicable to other BOS system components.
BS EN 62093 does not apply to photovoltaic modules. These are covered by IEC 61215 or IEC 61646.
BS EN 62093 does not apply to concentrator modules or to complete PV systems.
Specific electrical safety aspects are not part of BS EN 62093.
BS EN 62093 is applicable to lead-acid and nickel-cadmium cells and batteries. Other electrochemical storage systems will be included when they become available.
Who is BS EN 62093 - BOS components for PV systems for?
BS EN 62093 on BOS components of PV systems are relevant to:
- PV systems manufacturers
- PV power system manufacturers
- Photoelectric device manufacturers
- Solar energy engineering industry
- Solar panel manufacturers
- Product designers
- Quality control bodies
- Regulatory authorities
Why should you use BS EN 62093 - BOS components for PV systems?
In a photovoltaic energy system, the solar panel is the queen of the system. All other parts which contribute to the functioning comprise the BOS. It is essentially through the efficient functioning of these BOS components that one can control costs, enhance efficiency and modernize solar PV systems.
BS EN 62093 specifies documentation, testing, and test procedures for the design qualification of natural environments for BOS components for PV systems.
BS EN 62093 provides you with different levels of severity for the different service environments. Dust, fungus, insects, shipping vibration and shock, and protection class has been added to the appropriate environmental categories. The high and low temperature and humidity limits have also been modified for the appropriate service environments.
The purpose of this BS EN 62093 is to determine the performance characteristics of each BOS
components and to show, as far as possible within reasonable constraints of cost and time, that the component is capable of maintaining this performance after exposure to the simulated service natural environmental conditions.
Overall, adhering to best industry practises in accordance with BS EN 62093 can assist you in improving the performance and efficiency of BOS components for PV systems.
