(Photovoltaic: Basic Design Principles and Components)

Advantages of PV System

 Fuel source (i.e., the sunlight) is huge and essentially infinite.

 No emissions, no combustion, no pollution. 

 Low operating costs (no fuel).

 No moving parts (no wear).

 High reliability in modules (>20 years).

 Modular (small or large increments).

 Quick installation.

 Can be integrated into new or existing building structures.

 Can be installed at nearly any point-of-use.

 Daily output peak may match local demand.

 High public acceptance.

 Excellent safety record.

 No on-site operator required.

Disadvantages of PV System

 Fuel source is diffuse (sunlight is a relatively low-density 

energy).

 High installation costs (i.e., High initial capital investment).

 Poorer reliability of elements (e.g., batteries system).

 Lack of manufacturers for enable you a good choice of best PV 

system.

 Lack of economical efficient energy storage.

 Lack of infrastructure and limited access to technical services in 

remote areas.

 Photovoltaic system will require too much land area to ever
