Interview Questions.

Question 1. Capacity Of The Power Plant?

Answer :

Solar PV electricity plant life are specified in KWp, now not KWH. KWp approach Kilowatt Peak.  Please study this link for extra statistics.

So a quote for 100 KWp does now not assure that you will get one hundred units of energy in step with hour. Typically a one hundred KWp plant will produce 1, 50,000 to 1, 80,000 Units of strength according to yr. The real era each month, week, day and hour will rely upon different factors and vicinity.

Question 2. What Are The Parameters That Affect Actual Generation?

Answer :

Actual delivery of electricity will depend upon the subsequent parameters:

Sunshine intensity:  The version of solar’s intensity to your area. The records of this information is available for your specific place (range and longitude). You can look for it in MNRE database.

Angle of the solar to the established base: We typically suggest fixed tilt set up – because of this modules are fixed at an attitude and sunshine incident angle at the module will vary through the day.

 Ambient Temperature: Change in Ambient temperature impacts the sun cell temperature and in turn that it'll have an effect on the energy generated. You can observe the sun module specification to understand the energy de-score for numerous mobile temperatures.

Solar strength Interview Questions
Question three. What Happens When The Solar Energy Generated Is More Than What We Need Or If It Is Less Than What We Need?

Answer :

Solar electricity is infirm electricity, and that is why, we either sync it to the Electricity Grid or have a battery backup or Sync it to a DG set. For Industrial programs, we sync with grid or DG.

When the sun energy generated from the plant is less than what is required via your load, the additional required strength could be drawn from either grid or DG for imparting the load. If it is more than what is required, it is able to be fed returned to the Grid, furnished you've got a internet meter connection.

Question four. Can Sunshades And Porticos Be Used For Mounting Solar Panels In Addition To Roof Tops?

Answer :

In theory, Yes. But feasibility needs to be studied via an engineer during initial evaluation.

Question five. Can The Solar Plant Be Synchronized With Grid Power And Dg Power?

Answer :

Yes, it can be synchronized. Check the specifications of the inventors – it have to mention that it's far sync-able to each DG and Grid.

Question 6. Can Aepl Do A Turnkey Project From Design, Engineering And Supply To Mounting On Roof Top, Installation And Commissioning, Including The Electrical Circuit For Power Evacuation?

Answer :

Yes. The detailed scope of labor may be exact inside the commercial contract. Drawings can be submitted for patron’s approval.

Question 7. Can Aepl Take Care Of The Ceig Approval And Also Organize Net Metering Facility?

Answer :

Yes. There can be a liaising fee for the equal.

Solar Water Pumps Interview Questions
Question eight. Do We Need Lightning Arresters In Addition To What We Already Have In The Building?

Answer :

If the condition of the existing arresters is OK, then extra arresters may not be required. This can be ascertained for the duration of execution.

Question nine. Who Will Do The Earth Pit For The Solar Plant?

Answer :

Separate chemical earthing as much as 5ft as in step with wellknown layout norms may be constructed through us as part of our execution scope.

Question 10. Will The Mounting Of Solar Panels, Damage The Roof / Weathering Course? Will It Load The Roof?

Answer :

No harm could be precipitated due to mounting Solar panels. The extra weight of Solar panels might be within the load bearing capability of concrete and steel roofs. If consumer uses Asbestos roofing or if the roof is damaged in some locations, the same desires to get replaced / repaired by means of consumer.

The structural details of the mounting association may be submitted for patron’s approval earlier than graduation of the undertaking.

In case of concrete roofs, there are 2 primary processes:

Penetrative solving of modules:

In this example, sufficient care is taken in finishing the rooftop lower back after completing the inspiration to make certain that the consequent floor is equal or better than the unique surface.

Dead weight: 

If you are very strict that there must be no perforations, then we need to go for concrete legs so that it will characteristic as weights to preserve the module and structure.  We can design optimally, based totally on your requirements.

Question 11. Are There Are Any Safety Standards For Solar Power Plant?

Answer :

Yes there are posted protection requirements for roof top solar electricity flora. AEPL will make sure that the deliver and set up follows all the safety requirements applicable.

Question 12. Will You Guarantee The No. Of Units Produced Or The Efficiency Of Solar Plant?

Answer :

Yes we can guarantee the no. Of gadgets produced in step with year per KWp mounted. This guaranteed generation will vary from location to area. The actual assure figure could be integrated within the industrial agreement.

In any case since the agreement is based on price in step with KWH, if the plant produces much less, the sales is less.  This means, there may be an in-built guarantee and incentive for us to provide the most.

Question thirteen. Can The Solar Panel Withstand Wind, Rain And Seismic Conditions?

Answer :

Yes, the design looks after these types of situations, as relevant to the city / location of installation. The structural engineering and drawings on roof pinnacle set up could be submitted for consumer’s approval. This can be in addition validated through the customer with the help of a suitable architect  / expert.

Question 14. What Are The Warranty Terms?

Answer :

Solar PV Modules are included underneath a 20 year manufacturer guarantee with overall performance guarantee with the subsequent phrases:

90% minimum rated performance in 10 years.
Eighty% minimal rated overall performance in subsequent 15 years.
Inverters are blanketed with a 5 years guarantee with the following terms:

As in line with the Manufacturer.
All other systems, electrical wiring and other additives are blanketed by 1 yr guarantee.
Question 15. Do You Offer Amc?

Answer :

Yes. Please confer with our Warranty and AMC terms below:

Quarterly inspection of Solar Panels, Inverters,safety circuit, cabling junction boxes, manner of isolation and earthing for 5 years, 4 Visits for the entire machine.
Staff could be educated for cleaning as to offer a dirt loose surroundings for sun device.
The AMC might encompass whole alternative of breakers, fuses and relays if they're damaged.
Question 16. Do We Need Permanent Access To The Roof Top?

Answer :

Access required at some stage in creation and commissioning might be brief. However, periodic dirt cleansing of panels is important for better technology. So the solar panels should be easily handy even after commissioning. The additional systems if any for accessing the panels ought to be protected in the layout.

Question 17. What Are The Specifications For Output Power (like Voltage Range, Frequency Range, Power Factor, Thdi Etc.)?

Answer :

This will rely on the inverter version and specs, which can be observed within the statistics sheet enclosed with the thought.

Question 18. What Are The Documentations Provided?

Answer :

User Manual and Maintenance Manual can be supplied.
