Solar panel is a device that uses Photovoltaic(PV) technology to convert sunlight into electricity. They are often called PV modules as they are made up of multiple photovoltaic cells which generate direct current (DC) when exposed to sunlight.

Here’s how solar panels work:

1. Photovoltaic Effect: When sunlight hits the solar cells in a panel, it excites the electrons in the silicon atoms and causes them to flow and create an electric current.
2. Generation of Electricity: The solar cells within the panel generate direct current (DC). This electricity is then collected by conducting wires within the panel and directed towards the electrical load or stored in batteries for later use.
3. Inverter Conversion: Since most homes and businesses use AC current, the DC electricity generated by the solar panels needs to be converted into AC electricity. A solar inverter is installed alongside solar panels to carry out the DC to AC conversion.
4. Integration with the Grid: In grid-tied systems, the AC current produced by the solar panel is either consumed immediately by the electrical loads in the building or exported to the utility grid. When more electricity is generated than consumed, the excess can be sold back to the grid, often through net metering programs.
5. Powering Electrical Loads: The electricity generated by solar panels can power various electrical loads in homes, businesses, and other applications.
6. Energy Storage (Optional): In some cases, solar panel systems are equipped with battery storage to store excess energy generated during the day for use during periods of low sunlight or during power outages.

There are multiple reasons to buy solar panels, but it depends on your location and your power consumption. Solar panel is a long term investment that brings a series of benefits to all its users. 

1. Provides huge savings on electricity bills
2. Provides a continuous power supply in areas where there is limited/no grid supply
3. Significant contribution in saving the environment
4. Provides access to government subsidies and renewable energy schemes

The initial cost might sound scary, but in the long term, you save electricity bills on the large amount of units. Areas with frequent power cuts are the most beneficial users of the solar panels.

Once the panels are installed, you can power as many devices as the panels support. Depending on the load you can have 40W to 350W solar panels installed at your home, offices, factories, schools, farms, or any other location.

Solar panels are a cost effective alternative to regular electricity. The cost of solar panel installation varies depending on the type of solar panels and the technologies used in their manufacturing.

What factors affect the efficiency of solar panels?

Solar panel efficiency depends on:

• Amount of sunlight received
• Panel orientation and tilt
• Shading on roofs
• Panel quality

What maintenance is required for solar panels?

• Occasional cleaning to remove dirt.
• Inspection for any damage or issues.
• Ensuring proper electrical connections.
• Routine checks by a professional installer can help maintain peak performance.

In terms of quality, how do your solar panels compare to other solar panel companies in India?

UTL solar panels are built to last. We use highly efficient grade A solar cells to capture more sunlight and convert it into power. These cells are crafted from silicon and deliver strong performance even in low-light conditions. UTL’s durable frames protect the panels from harsh weather and can withstand 5400 Pa snow load and 2400 Pa wind load.

How much does 1 kiloWatt solar panel cost?

1kW solar panel price in India depends on the combination of solar modules that makes 1 kiloWatt. You can choose any combo based on your requirements.

• 5 x 200W solar panels cost approx. Rs. 33,000
• 3 x 335W solar panels cost approx. Rs. 33,500
• 2 x 540W solar panels cost approx Rs. 24,000

Can solar panels work during rainy or cloudy days?

Photovoltaic panels can generate current even during unideal conditions like rain or cloud. Although, their output may be reduced. However, modern UTL solar panels are designed to capture diffused sunlight and continue producing power even in less than ideal weather conditions.

How do I know if my home is fit for solar panel installation?

Homes with shadow free roofs are generally considered ideal for solar panel installation. You can easily request a free site evaluation from a solar panel manufacturer to get the best idea.

What happens to solar panels at the end of their lifespan?

At the end of their lifespan (typically 25-30 years), solar panels can be recycled to recover materials like silicon, glass, and aluminum. 

How does net metering work with solar panels?

Net metering allows rooftop solar panel owners to store excess energy from their solar system and export that extra power to the grid. This helps in significantly reducing the electricity bills in future.

What is the process of installing solar panels?

The installation process typically involves site assessment, design, obtaining permits, installation of panels and inverters, connection to the grid (if applicable), and final inspection. A professional installer handles each step to ensure a smooth installation.

What factors should I consider while planning to install solar panels?

You should keep the following in mind while planning to buy solar panels

1. Check if your rooftop has sufficient shadow free space

2. Find out the upfront costs of solar panel installation
3. Determine what type solar panels you want installed (Mono PERC, Polycrystalline, Half-cut/Bifacial)
4. Check the warranty of solar panels
5. Research the brands you wish to buy solar panels from
