Abstract
The conversion of solar energy into electricity makes it possible to generate a power resource at the relevant location, independent of the availability of the electrical network. The application of the technology greatly facilitates the supply of electricity to objects that, due to their location, cannot be connected to the electrical network. Typical areas of use are nature reserves, game management areas, large-scale agricultural areas, large-scale livestock areas, industrial pipeline routes, water resources far from infrastructure, etc. The protection of such areas and assets and the detection of their functionality are of particular importance, sectors classified as critical infrastructure are of paramount importance. This article aims to show the conceptual structure of a possible design of a high-reliability, redundant, modular, self-monitoring, microcontroller-controlled system that can be used in the outlined areas.
Highlights
Despite the arrival of many renewable energy sources, the vast majority of the world’s energy supply is still provided by fossil fuels, the extraction and use of which involves the release of large amounts of greenhouse gases into the atmosphere
The predominance of fossil fuels is leading to an increase in greenhouse gas emissions, which have recently grown at their fastest pace since 2013
We describe a method that significantly increases the redundancy of the photovoltaic system by duplicating the solar cells
Summary
Despite the arrival of many renewable energy sources, the vast majority of the world’s energy supply is still provided by fossil fuels, the extraction and use of which involves the release of large amounts of greenhouse gases into the atmosphere. By using cost-effective technologies [8], the pace of energy efficiency improvement can be greatly increased. Design principles such as modular device design, maintainability and traceability can serve this goal. In the field of off-grid power supply, a common approach to increase reliability and redundancy is to use hybrid systems, which could include for example photovoltaics, wind turbines or diesel generators [43]. We describe a method that significantly increases the redundancy of the photovoltaic system by duplicating the solar cells. The need for this and certain control issues will be analyzed
