Step-by-Step Guide: Installing a Solar Panel at Home

Solar power is a popular way to use renewable energy. Installing solar panels is a big step towards a greener future and lower electricity bills. This guide breaks down the installation process to help you get the most from solar energy.

Read on to learn more about solar installation and how it works.

5 Key Things to Consider Before Solar Installation

Certain factors must be considered before engaging in the installation process:

• Analyse the Energy Needs: The average energy consumption is expressed in kilowatt-hours (kWh). Understand the average consumed electricity for at least 3 to 6 months.
• Assess Your Solar Potential: Ensure the solar panels get plenty of sunlight all day by positioning them correctly. Keep them away from shadows caused by trees or buildings.
• Choose the Right Solar System: Select a grid-tie or an off-grid system. The on-grid system works with the frameworks and allows you to add extra power if needed. An off-grid system employs battery storage for power during blackouts or nighttime.
• Budget Planning: Calculate the total cost of the solar panel acquisition, including the costs of inverters, batteries, mounting structures and wiring. 
• Check Regulations and Permits: Ensure you adhere to the local regulations and get the necessary solar power panel installation permits. 

Step-by-Step Solar Panel Installation Process

Once you’ve evaluated your home’s potential and budgeted for the system, you can follow the below steps for successful solar PV panel installation.

1. Install the Mounting Structure

The mounting structure is the foundation for your solar panel installation. It has to be fixed securely with a tilt angle of 15-20 degrees to maximise sunlight exposure. Ensure the structure can withstand varying weather conditions in India.

2. Mount the Solar Panels

Position the panels onto the mounting structure and seal them using stainless steel nuts and bolts. Leave a small gap between panels to allow for thermal expansion, ensuring durability and efficiency during solar power panel installation.

3. Wiring the Panels

Connect the panels using MC4 connectors. Depending on your system:

• Series Connection increases voltage while maintaining current.
• Parallel Connection increases current while maintaining voltage.

Match the polarities correctly to avoid damage during the solar PV panel installation process.

4. Connect to the Inverter

The inverter changes the electricity from your solar panels into usable power for your home. When installing, connect the panel’s positive and negative terminals to the inverter correctly.

5. Integrate Battery Storage

This step is generally optional. For off-grid systems, connect the inverter to a battery. It will ensure that excess energy generated during the day is stored at night or during outages.

6. Connect to the Power Grid

In on-grid systems, link the inverter to your main power supply. This enables surplus energy to be fed back to the grid, earning you credits under net metering schemes.

7. Ensure Proper Earthing

Earthing is a critical safety measure during installing a solar panel on the roof. Use high-quality materials to ground the panels, inverter and other components effectively, protecting them from electrical hazards.

8. Test and Activate the System

Switch on the inverter and monitor the system’s output to ensure it functions as intended. Check the inverter display for real-time statistics on energy generation and usage.

FAQs Solar Panel Installation at home

Can you install home solar panels yourself?

Individual solar panel systems can be self-installed. However, it is agreeably advisable to hire a certified technician to avoid inconveniences like safety concerns, non-compliance with the law/regulations and system efficiency. Thus, professional installers also assist in warranty and system maintenance.

How many solar panels are needed to run a house?

This depends on the extent of power consumption and efficiency of the panels they are installing or proposing. It was found that an average Indian household uses 10–15 panels to avail the electricity it needs for daily use.

Can solar panels fully power a house?

Yes, a well-designed solar system can fully power a house. However, factors like energy usage, sunlight availability and whether you use battery storage or an on-grid system play a significant role.
