Safety features protect the solar PV system from being damaged or harming people in events, such as lightning, power surge or malfunctioning of equipment. The safety equipment consists of safety disconnect, grounding equipment, and surge protection.

Bi-directional meters (or “Net” Meters) are used to keep track of the electricity that solar PV system injects to utility grid and the electricity that is drawn from the utility grid.

Step by step guide for installation of rooftop solar

  • Express interest through website or mobile app or offline form - Residential Consumers can express interest by applying online, through offline form or the mobile APP for the installation of Solar Rooftop System
  • Select vendor for installing the system - The interest expressed shall be notified to registered solar installers, who will then contact you and visit your premises to assess the feasibility for installation of solar plant.
  • Feasibility study and Installation Agreement - Selected vendor will conduct feasibility study for installation of rooftop solar plant at your premises. After establishing feasibility, you will be presented with an option to enter into an agreement with the vendor for installation.
  • Application for Net – Metering
  • Installation and commissioning of Solar plant

Residential Consumers

Solar Photovoltaic modules and allied electrical equipment are installed on residential and commercial rooftops and connected to the power grid. These are known as Grid- connected Rooftop Photovoltaic systems. The GRPV system comprises of electrical and electronic equipment, such as solar modules, inverters, cables, switch gears, etc. When all these components are combined together and placed in open space facing sunlight, the system starts generating electricity proportional to the intensity of sunlight. The electricity, thus generated, can be used directly by the consumer. If consumer is not able to use complete electricity generated by GRPV system, the excess electricity generated can be fed to the utility grid (DISCOM network) and the units get adjusted in the electricity bill. It is important to mention here that 1 kW of solar PV plant can generate more than 1200 units of electricity in a year.


The function of each component of solar PV system is explained as follows:



Solar PV Modules - Solar PV Modules are in the form of flat, rectangular panels which convert sunlight directly into electricity. Multiple panels are connected together to form arrays as per the desired capacity of the system.


Solar Inverter - Solar Inverters convert the DC electricity produced by the PV panels into AC electricity which can then be consumed by appliances within the premises or injected into the DISCOM grid.



Mounting Structure: The mounting structure supports and holds the PV panels in place on the roof. The structure is designed depending on the roof type, structural strength, cost, wind loads, etc.


Wiring and cabling: DC cables are used to connect solar panels and connect the array with the inverter.
