The Project . . .

To get electricity at non electrified hours and save huge amount of money and carbon dioxide by using renewable source of energy.

Solar energy is one of the main source of energy available abundant in India. This presentation is based on Installation of Solar Photovoltaic System for a residence.

Preparing for Installation

Site Visit : Before planning, it is essential to visit the site and obtain the specific data needed to design and install the system.

Step 1 : Preparation of system Installation

Work Crew briefed on PV procedure and safety Hazards.

Component delivery scheduled.

Component safely stored until Installation.

Step 2 : Delivery of Mounting Structure

1. Height of House

2. Bringing Structure at Roof

3. Structure at Roof

Step 3 Foundation of Mounting Structure1. Foundation Material

2. Working with Foundation Materials

Step 4 Foundation Started on Roof

1. Gripping on Roof 2. Attaching Cement Bases

3. Making Area Wet and Clean 4. Putting Cement to Attach Base with Roof

5. Cement Preparation6. Cement Filling

7. Cement Settlement

8. Filling of Cement

9. Final base and Foundation shape

Above given were the pictures for foundation process.

Before fitting panels on structure, It needs to dry up for whole night and continuously needs water spray to harden up the cement and make foundation strong.

During spare time, checking wirings and accessories.

Step 6 : Panels Fittings Started

1. Taking First Panes to Fit

2. First Panel on Structure

3. Fitting of Panels on Another Structure

Step 7 : Checking Panels Inbuilt Wiring and Junction Box

1. Checking Panels Wiring

2. Panels Junction Box 3. Junction Box Internal View

Step 8 : Wiring Connection of Panels

1. Panels Connectors

2. Extending Panels Wires

3. Connecting Panels into Series Connection (Set of Two’s)

4. Connecting Each Two’s into Parallel

5. Fixing All Wires Together with J-Locks along Structure and Panels

6. Yellow Wire Taken as Positive and Blue as Negative and Sending Wires Down from Roof to Main Board

Step 9 : Connecting Batteries, Charge Controller, Inverter and Panels with

Main Board

1. Blue Solar Switch, Yellow MCB Switch and

White Main Board Switch

2. Charge Controller With Switches

3. Connecting Inverter with Switch, Batteries, and Charge controller

4. Batteries, Each set of Two’s in series and then in

Parallel

5. Charge Controller showing Green

Light as Batteries in Charging Mode

Step 10 : Inspecting and Checking Readings of Whole System

1. Final Roof - Morning

2. Whole Electrical System - Taking

Readings

3. Roof at Afternoon

4. Sunset Readings and Outputs

Whole system is designed in a way to use electricity in Four ways,

First we can use Solar Photovoltaic electricity and then government grid electricity. First we use government grid electricity and then stored Photovoltaic electricity from the batteries.

Only Solar Photovoltaic generated electricity without any consumption from government grid electricity.

Shut down whole Solar PV plant and only use only govt. electricity i.e. this may useful at the time of maintenance and repairing of the system.

System Design

To Conclude

Presently the residence is having 24 hours electricity with the investment of £3000. It is expected to save £45 every month from this PV system which gives a rough payback period of 6 years.

According to International Carbon Bank (ICBE) 0.75 tons of CO2 will be reduced per year. Thank You.
