As electricity consumption continues to rise, homeowners and businesses in Hyderabad are increasingly exploring solar energy as a way to generate electricity on their own property. Among the different solar configurations available, an on grid solar system Hyderabad solution can be particularly suitable for properties that already have a reliable electricity-grid connection.

Unlike an off-grid solar system, an on-grid system works together with the existing electricity grid. Solar panels generate electricity during the day, the property uses the generated power, and surplus electricity may be exported to the grid under the applicable metering arrangement.

Telangana has established provisions for grid-connected rooftop solar systems, including net and gross metering arrangements. TGREDCO states that eligible consumers can generate solar power for self-consumption and feed excess generation into the grid when it is not being consumed.

For households, offices, shops, institutions and industrial facilities, understanding how an on-grid system works can help when deciding whether solar is suitable for the property.

What Is an On Grid Solar System?

An on-grid solar system is a photovoltaic system connected to the local electricity grid.

The main components generally include solar panels, an inverter, mounting structures, electrical protection equipment, cables and the required metering and grid-connection components.

During daylight hours, the solar panels generate DC electricity. The inverter converts this electricity into AC power that can be used by appliances and equipment within the property.

If the solar system produces more electricity than the property is consuming at a particular time, the surplus can be exported to the grid under the applicable metering arrangement.

When solar generation is insufficient to meet the property's electricity demand, power can be drawn from the grid.

This makes an on-grid system different from an off-grid system, which generally relies on batteries to operate independently of the grid.

How Does an On Grid Solar System Work?

The working process is relatively straightforward.

1. Solar Panels Generate Electricity

Solar panels absorb sunlight and convert it into DC electricity.

The amount generated varies depending on factors such as sunlight, system capacity, panel orientation, shading, weather and system performance.

2. Inverter Converts the Electricity

The inverter converts the DC electricity generated by the solar panels into AC electricity suitable for use by electrical appliances and equipment.

3. Property Uses Solar Power

Electricity generated by the solar system can be used by appliances, machinery, lighting, air-conditioning systems and other connected loads.

4. Surplus Electricity Goes to the Grid

When generation exceeds the property's immediate consumption, surplus electricity can be exported to the electricity grid according to the applicable metering arrangement.

5. Grid Supplies Additional Power

When the property's electricity requirement is greater than the solar generation available, the additional electricity can be drawn from the grid.

This interaction between solar generation, property demand and the grid is what makes an on-grid solar system useful for many connected properties.

Why Choose an On Grid Solar System in Hyderabad?

Hyderabad has favourable conditions for solar generation. Milestone Solar notes that Hyderabad receives around 300 days of sunlight each year, while Telangana's renewable-energy agency also identifies substantial solar potential across the state.

An on-grid solar system can be considered by property owners who want to generate renewable electricity without adding battery storage to the basic system.

It can be suitable for:

• Independent houses

• Villas

• Apartment buildings

• Offices

• Shops

• Commercial properties

• Warehouses

• Schools and colleges

• Hospitals

• Factories

• Industrial facilities

The appropriate system depends on the property's electricity consumption, available roof area and applicable grid requirements.

Benefits of an On Grid Solar System

Reduce Electricity Bills

One of the main reasons people consider an on-grid solar system is to reduce electricity purchased from the grid.

Solar electricity generated during the day can be consumed directly by the property. Depending on the applicable metering arrangement, surplus generation may also be exported to the grid.

The actual savings depend on system capacity, electricity consumption, tariffs, solar generation and other project-specific factors.

No Battery Required in a Basic On-Grid Setup

A standard on-grid system does not require batteries to store electricity.

This can reduce the initial system complexity and eliminate the need for battery maintenance and replacement associated with battery-based systems.

For customers who already have a reliable electricity connection, this can make an on-grid configuration a practical option.

Use Existing Grid Infrastructure

An on-grid system works alongside the existing electricity connection instead of replacing it.

Solar generation can supply part of the property's electricity requirements, while the grid remains available when additional power is required.

Suitable for Daytime Consumption

Businesses and commercial facilities that use significant electricity during working hours may benefit from generating solar electricity when their loads are active.

Factories, offices, schools, warehouses and shops can evaluate solar based on their actual daytime electricity requirements.

Renewable Electricity Generation

Solar energy uses sunlight to generate electricity without direct fuel combustion at the point of generation.

For businesses with sustainability goals, installing solar can form part of a broader renewable-energy strategy.

On Grid vs Off Grid Solar System

Understanding the difference between on-grid and off-grid systems is important before selecting a solar solution.

An on-grid solar system remains connected to the electricity grid. It generally does not require battery storage in its basic configuration and can export surplus electricity under applicable metering arrangements.

An off-grid solar system operates independently from the electricity grid and typically requires batteries or another form of energy storage to provide electricity when solar generation is unavailable.

For a home or business that already has a dependable grid connection and primarily wants to reduce electricity costs, an on-grid system may be worth evaluating.

For a property where grid availability is limited or backup power is a major requirement, an off-grid or hybrid configuration may be more appropriate.

Net Metering in Telangana

Net metering is an important consideration when installing a grid-connected rooftop solar system.

TGREDCO explains that Telangana provides net and gross metering facilities for eligible consumers, allowing solar power to be generated for self-consumption and excess electricity to be fed into the grid under the applicable arrangement.

TGREDCO's current rooftop-solar information states that net-metering approvals are required from the respective DISCOM and identifies a maximum capacity of 1 MW under its stated net-metering programme, subject to transformer availability and the sanctioned consumer load.

The regulatory framework can change, so customers should confirm the latest eligibility, technical requirements, capacity limits and approval procedures with the relevant electricity distribution company before beginning a project.

Telangana's 2025 rooftop-solar regulations also provide for net metering, group net metering, gross metering and virtual net metering arrangements for eligible consumers, subject to the applicable conditions.

How to Determine the Right Solar System Size

There is no single solar capacity that works for every property.

The right size should be determined after considering:

Electricity Consumption

Review recent electricity bills to understand monthly and annual consumption.

Daytime Load

Determine how much electricity is consumed while the solar system is generating power. This is particularly important for commercial and industrial properties.

Available Roof Space

The roof needs sufficient usable area for the proposed number of solar panels. Water tanks, staircases, equipment and shading can reduce usable space.

Shading

Trees and nearby buildings can affect solar generation. A site assessment can help identify potential shading issues.

Sanctioned Load

The property's sanctioned electricity load and applicable grid requirements should be considered during system planning.

Budget

The available investment should be evaluated alongside expected electricity generation and potential savings.

A professional solar provider can use these factors to recommend an appropriate system capacity.

On Grid Solar System Installation Process

A typical installation involves several stages.

Site Assessment

The solar company evaluates the roof, electricity consumption, shading, electrical infrastructure and available installation area.

System Design

Based on the assessment, the provider determines the proposed solar capacity, panel arrangement, inverter configuration, mounting structure and electrical requirements.

Documentation and Approvals

For grid-connected systems, applicable applications, approvals and metering procedures need to be completed through the relevant authorities and DISCOM.

Installation

Solar panels, mounting structures, inverter and electrical components are installed according to the approved system design.

Testing and Commissioning

The completed system is tested to confirm that the components are operating correctly before the system is commissioned.

Metering

Where applicable, the required meter and grid-connection process is completed according to the prevailing regulations.

What Affects On Grid Solar System Cost?

The cost of an on grid solar system Hyderabad project depends on the complete system rather than only the solar panels.

Important cost factors can include:
