• Lower costs: The cost of solar panels and other components has been declining in recent years, making solar PV more affordable.
• Increased use of microinverters: Microinverters are small, individual inverters that are attached to each solar panel. This allows for more efficient energy production and reduces the risk of system failure.
• Emergence of new technologies: New technologies, such as perovskite solar cells and bifacial solar panels, are being developed that could further improve the efficiency and cost-effectiveness of solar PV.

6. Describe the process of installing a solar PV system.

• System design: The first step is to design the solar PV system, which involves determining the energy needs of the building or application, selecting the appropriate solar panels and inverters, and designing the system layout.
• Permitting: Once the system design is complete, it is necessary to obtain the necessary permits from the local authorities.
• Installation: Once the permits are obtained, the solar PV system can be installed. This involves mounting the solar panels on the roof or ground, wiring the panels to the inverters, and connecting the inverters to the electrical grid.
• Inspection: Once the system is installed, it should be inspected by a qualified electrician to ensure that it meets all safety and code requirements.
• Commissioning: The final step is to commission the solar PV system, which involves testing the system to ensure that it is operating properly.

7. What are the different types of solar cells?

• Monocrystalline solar cells: These cells are made from a single crystal of silicon and are the most efficient type of solar cell.
• Polycrystalline solar cells: These cells are made from multiple crystals of silicon and are less efficient than monocrystalline cells.
• Thin-film solar cells: These cells are made from a thin layer of semiconductor material deposited on a substrate. They are less efficient than monocrystalline and polycrystalline cells, but they are also less expensive.

8. What are the advantages and disadvantages of using solar PV systems?

Advantages:
• Solar PV systems can generate clean, renewable energy.
• Solar PV systems can help to reduce energy costs.
• Solar PV systems can increase the value of a property.
