Solar Energy Introduction
PV System directly converts solar energy into electricity. The basic building
block of a PV system is the PV Cell, which is a semiconductor device that
converts solar energy into direct current (DC) electricity.
The main components of grid tied system are modules, inverters, electrical
components and PV module mounting system.
Benefits of Solar Electricity:
Energy Independence.
Environmentally friendly.
Minimal Maintenance.
Maximum Reliability.
Reduce Vulnerability to power loss.
Systems are easily expanded.

• Market End –Use Sector:
There are four end – user sectors with distinct markets for PV:
• Residential Systems (typically up to 50kW systems on individual buildings / dwellings)
• Commercial Systems (Typically up to 1 MW Systems for commercial office buildings, Colleges, Hospitals, & Retail).
• Utility Scale Systems (Starting at 1MW mounted on buildings or directly on the Ground).
• OFF-Grid Applications (Varying Sizes)
• Typical PV System:

Classification PV technologies
Crystalline Silicon (c-Si) modules represent 85 – 90% of the global annual Market
today.
C-Si modules are subdivided in to two main Categories:
Single Crystalline (sc-Si)
Multi – Crystalline (mc – Si).
Thin Films currently account for 10% to 15% of global PV Module sales. They are
subdivided into three main families:
Amorphous (a-Si) and micro morph silicon (a-Si / µc-Si),
Cadmium – Telluride (CdTe)
Copper – Indium – Diselenide (CIS) and
Copper – Indium – Gallium – Diselenide (CIGS).

b. Power Conditioning Unit
Inverters take care of four basic tasks of power conditioning:
1. Converting the DC Power coming from the PV modules or battery bank to AC Power.
2. Ensuring that the frequency of the AC cycles is 50 cycles per second.
3. Reducing voltage fluctuations.
4. Ensuring that the shape of the AC Wave is appropriate for the application. i.e. a pure
sine wave for grid-connected systems.
Inverters are two broad classes of inverters:
1. Central Inverters.
2. String Inverters.

c. PV Module Mounting System Arrangement
Fixed Mounting systems keep the rows of modules at a fixed tilt angle, while
facing a fixed angle of orientation. Tilt angle is important for maximizing the
energy incident on the collector plane.
The Tilt angle and orientation is generally optimized for each PV Power plant
according to location. This helps to maximize the total annual incident irradiation
and total annual energy yield.
For Indian sites, the optimum tilt angle is generally between 10° and 35°, facing
true south. Fixed tilt mounting systems are simpler, cheaper and have lower
maintenance requirements than tracking systems.

d. AC Distribution
AC Distribution design is purely based on the system capacity, nearest grid
availability to the site. AC Distribution consists of major equipments like LT
Panels, Distribution Transformers, HT Panels and Control system for your
case connected to LT panel system or others.
