SOLAR ENERGY TECHNICIAN (253)

1. INTRODUCTION

Solar energy is a largest renewable resource freely available everywhere in adequate amounts, making it one of the most promising, clean, non-pollution source.
Currently a number of solar energy devices like solar cooker, solar water heater, solar photovoltaic pumps and solar photovoltaic lighting systems are gaining popularity. There is a need for generating manpower for installing and managing such solar based systems. This module is designed to train technicians who can install, maintain and promote the uses of such solar appliances.

2. OBJECTIVES

After going through this course the student will be able to:
understand the Basic Principles of Solar Technology, Solar Cooker, Water Heater, Solar Photovoltaic Lighting System, Solar Water Pumping etc.
install, maintain and promote the uses of solar applications.

3 JOB OPPORTUNITIES

Those completing this module can find employment in the nodal agencies of the Ministry of Non-conventional Energy Sources, voluntary agencies and other organizations promoting the technology at district and block levels.
Entrepreneurial opportunities would also be available in terms of opening shops for spare parts, servicing and sale of solar devices.
