FAQs: Solar Panels

Q. How do solar panels generate electricity?

Ans. The electricity generated by our solar panels uses the photovoltaic effect. Here, is the process given: 

• When sunlight strikes the solar panels, they absorb the sunlight. This happens because these panels are made of photovoltaic cells. And due to the sunlight strike, the electrons in the cells get excited and move around as a result.
• After this, these moving excited electrons make the electrical current flow from the PV cells to the solar panel’s circuit.
• As this current is direct current it cannot be used in homes and other places. So, this DC electricity is converted into alternating current electricity using an inverter.
• This inverter is further used to convert the DC current into AC electricity. After which the converted electricity is supplied to homes, offices, and other places to light bulbs, run equipment, and to perform other tasks..
• Apart from these, the electricity produced by our solar panels can be easily stored in batteries for future work. 

Q. How long do solar panels typically last, and what is their warranty?     

Ans. Solar panels provided by manufacturers depend on various features like material quality, design, and maintenance. In general, these panels easily last for 25 to 30 years. As time passes, these panels’ efficiency deteriorates, and as they get older, they may produce lesser electricity.

Most manufacturers offer a warranty that their panels will provide the desired amount of electricity for a particular time period. The warranty of these panels is 25 years, although it comprises both the performance and manufacturing defects.

Let’s make it clear that warranties for these panels mainly depend on the panels, not on the installation fees and other things. Also if any kind of natural calamities occurs, then it will not be covered under the warranty point. 

To have a better working of these panels for a long time period, do proper little care to these panels.
