Whom should I approach for installing subsidized grid connected rooftop solar plant in Goa?

The Goa Energy Development Agency (GEDA) is an autonomous body established by the Government of Goa with its headquarters at Saligao, Bardez-Goa. The agency is fully committed to boost the use of non-conventional and renewable energy sources. GEDA is the Nodal Agency, which interacts with the Ministry of New and Renewable Energy (MNRE), Government of India, New Delhi, to implement the centrally funded grid connected rooftop solar systems in Goa. A person can submit the interest for installation of rooftop solar plant through the “Single Window Clearance Portal” which is an online platform that handles the complete rooftop solar implementation application and approval process online. The “Single Window Clearance Portal for Goa” can be accessed through the link https://solarrooftop.gov.in/goa/

Why solar plants needs to be earthed?

The aim of earthing is to enhance the safety of the installation of solar plant by reducing the level of danger inherent to fault currents. Earthing prevents damage to the components as a result of flow of heavy fault currents. For rooftop solar plants earthing is done on both DC side as well as AC side covering components of the plant like modules, inverter, structure & lightning arrester.

What are solar DC cables?

Solar DC cables interconnect solar panels to the combiner boxes to inverter. The DC cables are usually two-core cables, a current-carrying live red wire and a negative blue wire, both are typically surrounded by an insulation layer. DC cables are generally made of copper conductors which provides more flexibility. As the life of the solar plant is expected to be more than 25 years, DC cables should be capable to withstand high temperatures, UV radiations, fire risk, expose to water etc.

What would happen if the solar panels deployed in the system have different electrical characteristics?

When solar panels with different electrical characteristics, interconnected with each other are deployed in the system, it creates serious power losses & adversely affects the overall energy generation. These losses are referred as “Mismatch losses”. The current (Isc) in the string in which the panels are connected in series with each other, is limited to the lowest output current from any of the panel. Thus mismatch causes the lower output power from the string & the system efficiency and performance becomes lower.
