Q2. What is solar how it works
Ans. 
Solar energy is the conversion of sunlight into usable electricity or heat.
• Solar energy is harnessed through the use of solar panels, which contain photovoltaic cells that convert sunlight into electricity.

• These cells are made up of semiconductor materials, such as silicon, that absorb photons from sunlight and release electrons, generating an electric current.

• Solar energy can also be used for heating purposes through ...read more

Q3. How many types of earthing are available
Ans. 
There are several types of earthing, including plate earthing, pipe earthing, rod earthing, and strip earthing.
• Plate earthing involves burying a large metal plate in the ground.

• Pipe earthing uses a metal pipe driven into the ground.

• Rod earthing utilizes a metal rod inserted into the ground.

• Strip earthing employs a metal strip buried in the ground.

• Each type of earthing is used to provide a safe path for electrical curre...read more

Q5. What type of inverter work you did? in solar
Ans. 
I have experience working with various types of inverters in the solar industry.
• I have worked with string inverters, which convert DC power from solar panels into AC power for use in the electrical grid.

• I have also worked with microinverters, which are installed on each individual solar panel and convert DC power into AC power at the panel level.

• Additionally, I have experience with central inverters, which are used in ...read more

Q6. How to distribute load in solar
Ans. 
Load distribution in solar refers to the allocation of power generated by solar panels to different electrical loads.
• Use a solar inverter to convert DC power from solar panels into AC power for distribution.

• Distribute the load by connecting electrical loads to the solar inverter's output.

• Consider the power requirements and capacity of each load to ensure balanced distribution.

• Implement load management techniques such a...read more

Q2. How many types of solar systems are here
Ans. 
There are mainly three types of solar systems: grid-tied, off-grid, and hybrid systems.
• Grid-tied solar systems are connected to the local utility grid and do not require batteries for energy storage.

• Off-grid solar systems operate independently from the grid and rely on batteries to store excess energy for use when the sun is not shining.

• Hybrid solar systems combine the features of both grid-tied and off-grid systems, a

Q1. Types of inverter
Ans. 
Types of inverters include grid-tie inverters, off-grid inverters, and hybrid inverters.
• Grid-tie inverters are used in systems connected to the utility grid.

• Off-grid inverters are used in standalone systems not connected to the grid.

• Hybrid inverters can operate in both grid-tie and off-grid modes.

• Other types include microinverters and string inverters.
