The main components include solar panels (modules), inverters, mounting structures, and a solar monitoring system. Panels capture sunlight, inverters convert the generated DC electricity to AC, mounting structures support the panels, and monitoring systems track energy production.

Solar panels can be installed on various roof types, including RCC slab, metal, tile, and flat roofs. The suitability depends on factors such as roof orientation, structure, and shading.

– On-grid solar systems use common solar inverters and are connected to the public electricity grid. Any excess solar power that you generate is exported to the electricity grid and one usually get paid a feed-in-tariff or credits for the energy you export. The policy for getting credits for energy exported to the credit is termed as “Net-Metering Policy” and is available currently in most states of India. Off-grid solar systems are not connected to the electricity grid and therefore requires battery storage. Hybrid solar systems combines solar and battery storage in one and are now available in many different forms and configurations. This means being able to store solar energy that is generated during the day and using it at night. When the stored energy is depleted, the grid is there as backup, allowing consumers to have the best of both worlds.

The production level of a solar plant depends on multiple factors like radiation levels, amount of sunlight received, plant design and quality of components. On an average, 1 kW solar plant produces 4 units of electricity per day.

On average, a standard residential solar panel system requires approximately 100 Sq.ft (9 Sq.m) of roof space for every kilowatt (kW) of installed capacity.
