Solar panels are super important for homes in Goa because there's lots of sunshine here. They help you save money on electricity bills which is extra useful when the power goes out. The portal was developed by the Goa Energy Development Agency in collaboration with the state's Department of New and Renewable Energy and Electricity. The cost of the rooftop solar subsidy will be shared between the state and central governments, providing applicants with a 50% discount on their eligibility.

Components of a Solar System

Solar Panels: Solar panels are the heart of any solar system. These panels are made up of photovoltaic cells that convert sunlight into electricity. Solar panels come in many variants like DCR solar panels, monocrystalline solar panels, and bifacial solar panels. The most prominent choice is bifacial solar panel for residential purpose.

Solar Inverter: Solar panels generate direct current (DC) electricity, but most of our household appliances use alternating current (AC). So, we need a solar inverter to convert DC into AC. On grid solar inverters are a crucial part of the system, they come in different sizes 3KW, 5 KW, 8 KW and 10 KW.

Solar Batteries (optional): Some solar power systems include batteries to store excess electricity for use during cloudy days or at night. This is especially valuable in places with unreliable grid power, making sure you have electricity even when the sun isn't shining.

Mounting Structure: Solar panels need to be securely mounted on rooftops or the ground. The mounting structure not only keeps them in place but also ensures they are at the right angle to receive maximum sunlight.

Charge Controller (if using batteries): The charge controller regulates the flow of electricity to and from the batteries, preventing overcharging and prolonging battery life.

Wiring: Proper wiring are essential to connect all the components of the system safely and efficiently. These wires transport electricity from the solar panels to the inverter, batteries (if present), and then to your home or the grid.

How to apply for Net Metering?

Net metering is important for solar subsidies in Goa because it helps more people use clean energy. With net metering, solar panel owners can sell extra electricity back to the DISCOM and earn money. This encourages more people to choose solar power, which is good for the economy.

To apply for a net meter in Goa, follow these simple steps:

  1. 1. Click on Goa Solar Rooftop Portal website.
    2. For those in the Residential category seeking a subsidy, please opt for 'Subsidy Based RTS Installation.' For applicants in other categories, please select 'Non-Subsidy Based RTS Installation.'
    3. Now, The applicant have to fill the following details:
    • Name
    • Email
    • Mobile Number
    • Consumer Category
    • Pincode
    • Captcha
    4. After submitting the 'Consumer Interest Form,' the applicant will need to choose three installers for the rooftop solar installation.
    5. Then click on submit.

Type of Rooftop Solar System

On Grid Solar System: If you want to reduce your electricity bill up to 80% then on grid solar system is an optimal choice for you. An on-grid solar system, also known as a grid-tied solar system, that system is connected to the electricity grid, and this will help you to save money form the electricity bills. As well as you can sell excess generated electricity back to the DISCOM and earn money with that.

Off Grid Solar System: If you live in a remote area or experience frequent power cuts, you may want to consider an off-grid solar system. An off-grid solar system includes batteries to store excess power for use during times when the sun is not shining.

Hybrid Solar System: A hybrid solar system is a combination of an “on-grid” and “off-grid solar systems”. It is basically a grid connected system that comes with a battery backup. So, it has the advantage of both you can store excess power in the battery for use during an emergency time as well as you can sell the surplus generated power to the grid and earn money.

According, to the solar professional “Hybrid Solar System” is the optimal choice because from this you can reduce your electricity bill as well as get power backup during emergency time. This makes it a popular choice for residential installations.

Solar Panel Subsidy Scheme

Both central and state government offer subsidies schemes to people for installation the rooftops solar system.

Central government subsidy scheme:

Central government subsidy scheme is known as DBT (Direct Bank Transfer). In this scheme the subsidy amount will be directly transfer into the customers bank account with in the 30 days of commissioning of the solar system. You can get central government subsidy by applying through the National Portal for Solar Portal

State government subsidy scheme:

At present, the MNRE gives 40% subsidy for domestic consumers who install 1kW to 3kW rooftop solar power plants with the state government providing an additional 10% subsidy. Rooftop solar plants with a capacity between 4kW and 10 kW attract 20% subsidy from MNRE with Goa providing an additional 30% subsidy.The Union ministry is now shifting to a fixed subsidy which GEDA will also adopt.

    Solar Panel Subsidy Price

    Capacity Central Subsidy State Subsidy 
    2 KW 29,176
    3 KW 43,764
    4 KW 51,058
    5 KW 58,352
    6 KW 65,646
    7 KW 72,940
    8 KW 80,234
    9 KW 87,528
    10 KW 94,822

    Both central and state offers the solar subsidy, for the general category states the central government pay 30% amount for the total as a subsidy. But for special states like Himachal Pradesh, Uttarakhand, Sikkim, J&K and Lakshadweep the central government pays the 70% subsidy amount. If your state doesn’t offer the subsidy on solar you can avail the central government subsidy by applying through the National Portal for Solar Portal

    If you want to interest in getting a subsidy you need to follow some guidelines. You must contact the electricity provider or DISCOM and apply online with the necessary documents. Their person will visit your site for a review and gives you an approval. Then the electricity provider visits for inspection. Customers can then avail the subsidy amount.

    What is the entire process?

    To apply solar subsidy, you should follow the following steps:

    Step 1: Site Survey. Book Engineer Visit from here.

    Step 2: System Capacity, Costing & Performance Analysis

    Step 3: Buy Solar System & Installation

    Step 4: Apply for Net Metering

    Step 5: Get Solar Subsidy after 30 days of rooftop solar panel installation.
