MANPOWER REQUIREMENTS FOR SOLAR PV DEVELOPMENT

Project planning
Activities at the project planning phase comprise site selection, technical and financial feasibility studies, engineering design and project development. The first two activities involve measuring the solar resource potential and estimating the environmental and social impacts of developing a solar plant on an identified site. Engineering design involves identifying the technical aspects of the mechanical and electrical systems, the civil engineering work and infrastructure, the construction plan and the operations and maintenance (O&M) model. Project development consists of administrative tasks such as obtaining land rights, permits, licenses and approvals from different authorities; managing regulatory issues; negotiating and securing financing; negotiating and signing insurance contracts; contracting an engineering company; negotiating the rent or purchase of the land; and managing the procurement processes.

EXAMPLE: Planning a 50 MW solar PV plant requires an estimated 2,120 person-days of labour. Project development activity accounts for about 59 percent of this labour (1,250 person-days), followed by site selection (17%), engineering design (12%), and feasibility analyses (12%). Table 1 presents a breakdown of the total workforce needed in project planning by activity.
Almost 40 percent of the total person-days needed are for legal, energy regulation, real estate and taxation experts.

THE TOP GOVERNMENT PROGRAMES IN THE SOLAR SECTOR

January 16, 2018

Below are top government programme initiatives taken by the government in the solar sector to push more and more individuals and companies globally to go solar and 100% renewable:

Jawaharlal Nehru National Solar Mission

– The Jawaharlal Nehru National Solar Mission was launched in January 2010 by former Prime Minister, Dr. Manmohan Singh. Its aim is to reduce the cost of solar power generation and install 20,000MW of grid-connected solar power. 

Rooftop Scheme

– Under the rooftop scheme executed by SECI (Solar Energy Corporation of India), 200 MW of projects has been allocated, out of which 45 MW of capacity have been commissioned. Addition to this, special schemes including 73 MW for warehouses and 50 MW for the CPWD (Central Public Works Department) have been launched. 

Solar Park Scheme

– MNRE has come up with a scheme to set up a number of solar parks across several states, each with a capacity of almost 500 MW.  The solar park will enable states to bring in investment from project developers and offer employment opportunities to the local population.

VGF (Viability Gap Funding) Scheme –

Viability Gap Funding scheme is implemented by SECI. In the past few years, SECI has made multiple project allocations under the VGF mechanism. The first 750 MW allocation has already been executed of which 680 MW capacity has been installed and commissioned. VGF support will be provided for setting up of grid-connected solar PV projects of a minimum 2000 MW capacity by solar power developers on build own operate basis.

Government Yojana Solar Energy Subsidy Scheme –

Under this Scheme, financial assistance and capital subsidy will be provided to the applicant to the extent of 50 percent, 75 percent and 90 percent of the basis of basic cost of the solar energy plant.

UDAY Scheme

– UDAY or Ujjwal Discom Assurance Yojna was launched in November 2015 as a revival package for electricity distribution companies of India initiated by the Government of India with the idea to find permanent solar power solutions to the financial mess that the power distribution was facing at that time.

PV Solar Guarantees Warranties and Insurance

Guarantees, Warranties and Insurance

In case of Solar PV systems, the solar panel and most other equipment manufacturers offer guarantees and warranties. Before finalizing/signing the purchase contract with the solar installer, you should ensure to check the warranty and guarantee terms of Solar PV components and system. Some of them are mentioned below:

Solar PV Panels

  • 10 years of product warranty against defect on materials and workmanship
  • Performance Guarantee of 25 years. In most of the cases, this guarantee is for 10 years at 90% of rated peak power output and for 25 years at 80% of rated peak power output. Peak power output is the nameplate capacity of a Solar PV panel.

Solar PV panels degradation trend

Degradation of solar PV panel should not be above 2.0% for first year, 8.0% for next 11 years and should not be above 9.0% linear for 13 years to follow thereafter.

Inverter

Typically inverter warranties last for 5 years; however installer or manufacturer may give extended warranties for a period of 20 years though for a fee.

Mounting Systems

Generally suppliers provide 5 to 10 years product warranty against any manufacturing defect

Solar PV System Warranty

Installers give you workmanship warranty for a period of 1~2 years or even more in some cases. It includes repair/replacement against manufacturing defects and engineering defects.

Plant performance guarantee

Generally Installers provide plant performance guarantee for a predetermined period of at least 1 to 2 years or even more in some cases. Plant performance percentage value should be pre-determined and mentioned in the purchase contract agreement. In addition, you may ask for additional guarantees like Liquidated Damages for delay in execution or poor performance, etc.
Have more queries? Contact Us and we will be happy to answer those.

System Insurance

Most insurance companies now offer insurance products for Solar PV systems. Typically, the premium amount for a policy that covers fire & burglary of the system would be approximately 0.75% of sum insured/ capital cost. For example, if you have a 1 kWp solar PV system which costs approx. Rs. 65,000/-, your payable annual insurance premium will be approximately Rs. 487.50 under Fire & Burglary coverage. However, it is recommended that you take quotes from multiple insurance companies before you choose one.

Small Rooftop Solar Power Plant Calculation

Rooftop solar is increasingly cost-effective for home owners, business owners, and their communities. Reductions in technology prices, innovative financing, and growing networks of solar installers and financial partners all helped drive down the prices for household systems in India. 

 The falling price of rooftop PV systems results from improvements in the technology and economies of scale among manufacturers. 

Many home owners and businesses are taking advantage of third-party ownership options. Under solar leases or power purchase agreements, electricity customers typically pay little or nothing up front for rooftop systems, then get electricity from the systems over a long period. The falling prices and innovative financing structures mean that rooftop solar is more broadly available, and that the pool of customers comes from increasingly diverse economic backgrounds.

How to design of your rooftop power plant?

Step – 1
Load Calculate
Application
Load (Watt)
No
Hours of Use
Wh/Day















Total Application Load(Lw)=


H=

Total Load in Wh/Day (EL)=

Total Load in KWh/Day =


Step – 2
SIZING AND CHOICE OF ELECTRONIC COMPONENTS:
Once the load assessment process is complete, the next step is to choose suitable electronics for the PV system namely the Inverter and Charge controller.  The capacity of these components depends on the voltage and current of the loads.

ESTIMATION OF REQUIRED INPUT ENERGY TO THE INVERTER:
calculate the input energy that must be fed to the inverter to get sufficient output energy to meet the demand of load.  

Step 3:
DETERMINING THE SIZE OF BATTERY BANK:
BATTERY PARAMETERS & BATTERY SIZING:
In order to find out the size of the battery, we have to consider the following parameters of batteries.
•          System Voltage and Ampere-hour capacity of the battery
•          Depth of Discharge (DoD)
•          No. of days of autonomy

ESTIMATING AMPERE-HOUR CAPACITY OF THE BATTERY:
The most common measure of battery capacity is Ah, defined as the number of hours for which a battery can provide a current equal to the discharge rate at the nominal voltage of the battery. Ah capacity of the battery can be calculated by dividing the energy input to the inverter (Output energy from battery) by System voltage.

ESTIMATION OF REQUIRED INPUT ENERGY TO THE BATTERY:
In practice, the battery efficiency may not be 100% and hence the entire energy supplied by the PV module may not be obtained from the output of battery bank. 

PV Array Design
Say, this system will be install at Jaisalmer, Rajasthan (Latitude:26.9157487, Longitude:70.9083443)
Average Radiation kWh/m2/day: 5.89, Max in May: 7.52, Min in December: 3.97 kWh/m2/day
Max, Min and Average Temperature(°C/°F): 43, 30, 38 in May Month

Required PV Array Power (Application required)=  

(TotalLoadinKWH/day)/(System’s efficiency factor X AverageSolarIrradiation)   X   PSI

Now make array as per inverter Specification
Operating Voltage Maximum Voltage and Minimum Voltage Range, check temperature co-efficient factor, MPPT Voltage range, Charging Current. It may be required to make trial and error method, change inverter VA for best suit.
