77 Solar Panel Technician Questions And Answers

41⟩ Tell us what Are The Parameters That Affect Actual Generation?

☛ Sunshine intensity: The variation of sun’s intensity in your location. The history of this data is available for your specific location (latitude and longitude). You can look for it in MNRE database.

☛ Angle of the sun to the installed base: We normally propose fixed tilt installation – which means modules are fixed at an angle and sunshine incident angle on the module will vary by the day.

☛ Ambient Temperature: Change in Ambient temperature affects the solar cell temperature and in turn that it will affect the power generated. You can look at the solar module specification to know the power de-rating for various cell temperatures.

42⟩ As you know at First Solar we offer a range of equipment and services. How familiar are you with our business?

I have read up on First Solar GmbH quite extensively since being invited to interview with you. From my understanding, the bulk of your business comes from A, and B. I read the press release posted to your blog last month and see that you are opening a new location in XYZ. Congratulations on that growth! I am very excited to join an organization as successful and progressive as yours.

43⟩ Tell me how is a solar electric system designed, installed, and maintained?

You could install a photovoltaic (PV) or solar electric system yourself. But to avoid complications or injury, you will probably want to hire a reputable professional contractor with experience in installing solar systems. PV systems have few moving parts, so they require little maintenance. The components are designed to meet strict dependability and durability standards so they can stand up to the elements. However, they are fairly sophisticated electric systems, so installation usually requires the knowledge and experience of a licensed electrical equipment contractor.

44⟩ Tell us what are the components of a photovoltaic (PV) system?

A PV system is made up of different components. These include PV modules (groups of PV cells), which are commonly called PV panels; one or more batteries; a charge regulator or controller for a stand-alone system; an inverter for a utility-grid-connected system and when alternating current (ac) rather than direct current (dc) is required; wiring; and mounting hardware or a framework.

49⟩ As you know the electrical equipment industry is vast. What area do you consider your specialty and why will your specialty help us at First Solar?

I have approximately 12 years experience in the electrical equipment industry with 6 of those years being on equipment nearly identical to what you have in place at First Solar GmbH. In your job posting you requested candidates with exposure to A, B, and C. In my current role I am considered the subject matter expert with A, and C. My understanding of B can be classified as intermediate level. If hired, my training time would be minimal compared to someone with less comprehensive experience within A, B, and C.

50⟩ Please explain why should I purchase a PV system?

People decide to buy solar energy systems for a variety of reasons. For example, some individuals buy solar products to preserve the Earth's finite fossil-fuel resources and to reduce air pollution. Others would rather spend their money on an energy-producing improvement to their property than send their money to a utility. Some people like the security of reducing the amount of electricity they buy from their utility, because it makes them less vulnerable to future increases in the price of electricity.

If it's designed correctly, a solar system might be able to provide power during a utility power outage, thereby adding power reliability to your home. Finally, some individuals live in areas where the cost of extending power lines to their home is more expensive than buying a solar energy system.

51⟩ Tell us how much does a solar water-heating system cost?

Unfortunately, there is no one answer to this question. The cost of a solar system depends on a number of factors, such as the size of the system and the particular system manufacturer, retailer, and installer. However, any solar rebates and other incentives available in your area will reduce that total cost.

For solar water heaters and space heaters, you will also be taking into consideration the price of the fuel used to back up the system. In most cases, you will have to add in the cost of supplemental natural gas or electricity to get a fairly accurate estimate of how much you can expect to pay for a solar system.

60⟩ Tell me what does BOS mean?

Balance of System. This means the rest of the component parts and equipment used in a Solar system that is NOT the solar modules. The remaining portion of the PV system, inverters, disconnects, wiring, conduits, NOT including the PV Modules.
