1.     Solar-Powered Vehicles: What Are They?

Meaning and Objective

Cars with photovoltaic panels that absorb sunlight and transform it into electrical energy are known as solar-powered cars. The car can move without using conventional gasoline thanks to the energy that is stored in batteries and utilized to power its electric motor. These cars' primary objective is to offer a greener substitute for engines that run on gasoline and diesel.
Vehicle Types Powered by Solar Energy
Vehicles of many kinds make use of solar technology to varied degrees:

1. Cars with full solar power: Although this technology i

 still in its infancy and is only utilized in concept and experimental cars, these vehicles are powered solely by solar panels.

2.     2. Solar-Assisted Electric Cars: These cars increase efficiency and driving range by using solar panels to augment their primary power source, which is usually an electric battery.

3. Solar-Powered Bicycles and Scooters: Solar panels are

adadvantageous for smaller vehicles such as bikes and scooters because they can charge batteries to power the electric motor.
How Do Vehicles Powered by Solar Energy Operate?
Photovoltaic cells and solar panels
Vehicles that run on solar power have solar panels that are composed of many photovoltaic (PV) cells. The semiconductor materials used to make these cells—typically silicon—absorb sunlight and produce energy. The PV cells' internal electrons are excited by sunlight, which moves them and creates an electric current. The car's battery is then charged by channeling this current.

3.     Storage of Batteries

Rechargeable batteries, often lithium-ion, store the electricity produced and power the car's electric motor. The driving range of the car is greatly influenced by the size and capacity of these batteries.
System of Power Management
Controlling the electrical flow between the solar panels, battery, and electric motor is the responsibility of a power management system. By charging the battery when there is enough sunshine and switching to battery power when solar energy is not available, it makes sure the car uses solar energy effectively and optimally.

4.     Advantages of Solar-Powered Automobiles
1. Eco-friendly

The low environmental impact of solar-powered cars is one of their main benefits. These vehicles are a more environmentally friendly option than conventional fuel-powered automobiles since solar energy is a clean, renewable source that emits no harmful pollutants.

2. Lower Energy and Fuel Prices

5.    
Fuel expenses are greatly decreased by solar-powered automobiles as they don't need gasoline or diesel. The possible fuel savings over the course of the vehicle's life may offset any high upfront expenditures.

3. Minimal Maintenance Needs

6.    
Compared to conventional cars, solar-powered vehicles often require less maintenance since they have fewer moving components. Compared to internal combustion engines, electric motors are typically easier to use and more dependable, which results in fewer mechanical problems and longer-lasting parts.

7.     4. Increased Electric Vehicle Range

By giving the battery more electricity, solar panels can increase the driving range of hybrid or solar-assisted electric cars. Those who need to go farther between charges will find this feature especially helpful.

5. Silent Function

Because they run more silently than traditional engines, electric and solar-powered cars help to lessen noise pollution in cities. Both the motorist and any nearby pedestrians may have a more tranquil and enjoyable driving experience as a result.

     Solar-Powered Vehicles' Drawbacks

1. Inadequate Energy Efficiency

When compared to fossil fuels, solar energy's energy conversion efficiency is relatively poor. Only 15% to 20% of sunlight is converted into power by the majority of commercial PV cells. This restricts how much electricity a solar-powered car may produce, particularly

 under overcast conditions or at night.
