18	Designs of Solar Panel and Wind Turbine Energy Systems

Solar panel and wind turbine energy are clean and renewable energy sources. In recent years their applications have drawn much attention all over the world. Therefore, the topic of design of solar panel and wind turbine energy systems is a very popular research field.

18.1  INTRODUCTION

First, we introduce sum units to measure large power. They are grouped by orders of magnitude as follows. The energy unit Joule (1 J = 1 W × 1 s):

•  kW—kilowatt (10³ W)

•  MW—megawatt (10⁶ W)

•  GW—gigawatt (10⁹ W)

•  TW—terawatt (10¹² W)

•  PW—petawatt (10¹⁵ W)

•  EW—exawatt (10¹⁸ W)

•  ZW—zettawatt (10²¹ W)

•  YW—yottawatt (10²⁴ W)

The Sun radiates the power of 3.8 × 10²⁰ MW into space. The Earth ...
