Cost Effective and Reliable Monitoring of Photovoltaic Plants using Specialized Isolation Amplifiers
In many cases, the investments intended to increase the efficiency of solar energy plants require a disproportionately high financial expenditure. On the other hand, centrally installed current and voltage metrology in the inverters based on isolation amplifiers can kill two birds with one stone: It increases the efficiency while saving money because it makes decentralized measurements superfluous.
Now that the phase of pure research and prestige objects in solar plants has come to an end and government support has been cut back, the highest priority in the competition of suppliers and systems is optimal cost-effectiveness. The main focus here is placed on the highest possible energy yield to ensure efficient plant operation.
But at the same time one needs to keep an eye on the expenditures required for continuously improving the plant efficiency. Increasing the efficiency by the last tenth of a percentage point doesn't help if the costs increase disproportionately and the amortization time extends by months or even years. An increase in the efficiency with little or even no expenditure would be ideal – a real challenge.
