Reduce your electricity bills by 90%
Just 1.5 hours of sunlight can power the world for a year. This shows the huge benefit of solar energy. At Fenice Energy, we’ve used the sun for over 20 years to give homes and businesses in India clean power.
Solar power comes from the sun and doesn’t hurt the earth. The carbon footprint of solar panels is tiny because they last over 25 years. People first used sunlight in the 7th century B.C to make fires. The idea of turning sunlight into power came in 1839, and the first solar cell was made in 1954.
Now, solar power is used in space to run satellites. This shows how well solar energy works. Let’s explore how solar PV panels work.

Introduction to Solar PV Panels
The sun provides an endless supply of energy. This makes solar power both clean and sustainable. Solar power is about turning the sun’s light into electricity or heat. The process uses the photovoltaic (PV) effect, discovered in 1839 by Edmond Becquerel.
What is Solar Power?
Solar power is a way to use the sun’s energy. It turns sunlight into electrical or heat energy. The sun gives off a lot of energy, and we can capture a huge amount of it. For example, the sunlight that reaches the earth in an hour and a half could meet the world’s energy needs for a year.
The History of Solar Power
People have been using solar energy since the 7th century B.C. They used it to make fires by reflecting sunlight off shiny objects. By the 3rd century B.C., the Greeks and Romans used mirrors to light torches for ceremonies. The 19th century brought a key discovery, the photovoltaic (PV) effect. This discovery led to the creation of solar cells and panels.
Bell Labs made the first solar cell that could produce power in 1954. This was a huge step forward for solar technology.
How Do Solar PV Panels Work?
Solar panels change sunlight into electricity thanks to the photovoltaic effect. This effect happens when sunlight hits the semiconductor material in the panels. Then, the material releases electrons and a charge is created. This charge is then turned into electrical current that we can use.
The Photovoltaic Effect
The photovoltaic effect makes solar panel technology possible. Light gets converted to electric energy by the material in the solar panels. As soon as sunlight hits the panel, an electric field is created. This lets the ‘excited’ electrons start moving, creating a direct current (DC).
Generating Electricity from Sunlight
This process is how solar panels produce solar power. The electricity you get depends on how much sunlight there is, the type and size of your panels, and where they point. When sunshine interacts with a panel, it triggers the photovoltaic effect. Then, DC power is made ready for your use.
Direct Current to Alternating Current
But, the electricity from solar panels is direct current (DC), not like the electricity in our homes, which is usually alternating current (AC). So, we need an inverter. The inverter changes the solar electricity to AC. This way, it can power our homes or go back into the grid.
Solar PV vs. Solar Thermal
Homeowners and businesses can choose between solar photovoltaic (PV) panels and solar thermal systems to use the sun’s power. Each works differently and is best for specific uses.
Understanding the Difference
Solar PV panels turn sunlight into electricity through a process called the photovoltaic effect. When sunlight hits the panels, it interacts with silicon to produce electricity. This electric current is then changed from direct current (DC) to alternating current (AC) for use everywhere.
Solar thermal systems, on the other hand, heat water or fluids with the sun’s heat. They have dark panels that soak up the sun’s warmth. This heat is then moved into a tank or into a building’s heating system. These systems are great for making hot water at home and heating spaces efficiently.
Choosing between the two depends on what you need. If you want to make electricity, go for solar PV. For warming water or heating spaces, solar thermal is a better pick. Fenice Energy has both options, plus tons of clean energy experience, to help you choose what’s right.
Solar Farms and Large-Scale Solar Energy
Solar farms are becoming key players in the push for more renewable energy. These large areas of land have many solar panels. They work together to collect solar energy. This energy is then sent into the power grid for everyday use. It offers a clean and green choice over using fossil fuels.
What are Solar Farms?
Solar farms are not like the solar panels on a house. They are much bigger. They are made to produce a lot of electricity. Thousands of solar panels are set up on massive pieces of land. This arrangement helps to catch as much sunlight as possible.
Advantages of Solar Farms
Solar farms are great for making large amounts of clean power. But they also help nature. They create homes for plants and animals without causing much noise. This makes them better for the environment than traditional power sources.
| Advantages of Solar Farms | INR (in Crores) |
|---|---|
| Large-scale renewable electricity generation | 2,500 |
| Support for local biodiversity | 1,800 |
| Lack of noise pollution during operation | 1,200 |
Fenice Energy leads with over 20 years’ experience in clean energy. They offer everything from solar to EV charging. Solar farms are a big step towards a brighter future for energy.
Factors Affecting Solar Panel Efficiency
Solar panels get their power from the sun. Different things can change how well they work. The amount of sunlight, the type of panels, and where they are placed all matter. These factors help the panels work as best as they can.
Sunlight Availability
More sunlight means more power for solar panels. Even on cloudy days, they can still make some energy. How much they can make changes with the sun’s direct rays. This is affected by the time of day and the seasons.
Panel Quality and Size
Better quality and bigger panels work more efficiently. High-quality panels use the sun’s energy better. The number and size of panels also matter. More panels mean more power, so does the size of each panel.
Location and Positioning
Where you place your solar panels is very important. The direction they face and how tilted they are can make a big difference. Shade from buildings, trees, or other objects can decrease their efficiency. Placing panels where they get the most sunlight is crucial.
