Essential Interview Questions For Electro-Mechanical Solar Technician
1. Explain the steps involved in the installation of a photovoltaic (PV) system?
- 1. Site assessment and design
- 2. Permitting
- 3. Equipment procurement
- 4. Installation
- 5. Inspection and commissioning
- 6. Customer training
2. What are the different types of solar cells and how do they compare in terms of efficiency and cost?
Monocrystalline solar cells
- Made from a single crystal of silicon
- Highest efficiency (typically 15-20%)
- Most expensive
Polycrystalline solar cells
- Made from multiple crystals of silicon
- Lower efficiency (typically 13-16%)
- Less expensive than monocrystalline cells
Thin-film solar cells
- Made from a thin layer of semiconductor material
- Lowest efficiency (typically 5-12%)
- Least expensive
3. Describe the function of a solar inverter and how it converts DC power to AC power?
- A solar inverter is an electronic device that converts the DC power produced by a solar panel into AC power that can be used by appliances and devices.
- It does this by using a process called pulse-width modulation (PWM) to create a sine wave that alternates between positive and negative voltages.
- The frequency of the sine wave is typically 60 Hz in the United States and 50 Hz in Europe.
- The voltage and current of the sine wave are determined by the power output of the solar panel.
4. What is the difference between a grid-tied solar system and an off-grid solar system?
- Grid-tied solar systems are connected to the electrical grid
- They can sell excess solar power back to the grid
- They are typically less expensive to install than off-grid systems
- Off-grid solar systems are not connected to the electrical grid
- They must store excess solar power in batteries
- They are typically more expensive to install than grid-tied systems
5. What are the advantages of using solar energy?
- Solar energy is a renewable resource
- Solar energy is clean and does not produce greenhouse gases
- Solar energy can help to reduce your energy costs
- Solar energy can increase the value of your home
6. What are the challenges of using solar energy?
- Solar energy is intermittent
- Solar energy can be expensive to install
- Solar panels can be damaged by extreme weather
7. What are the different types of solar mounting systems?
- Roof-mounted systems are attached to the roof of a building
- Ground-mounted systems are installed on the ground
- Pole-mounted systems are mounted on poles
8. What are the different types of solar trackers?
- Single-axis trackers move on a single axis, either east-west or north-south
- Dual-axis trackers move on two axes, allowing them to track the sun throughout the day
9. What are the different types of solar batteries?
- Lead-acid batteries are the most common type of solar battery
- Lithium-ion batteries are more expensive than lead-acid batteries, but they have a longer lifespan and can store more energy
- Flow batteries are a newer type of solar battery that uses a liquid electrolyte
10. What are the different types of solar charge controllers?
- PWM charge controllers are the most common type of solar charge controller
- MPPT charge controllers are more expensive than PWM charge controllers, but they can increase the efficiency of a solar system
