Wind and Solar Power - Renewable Energy Technologies
Jun 19, 2015
The past ten years has seen a significant increase in applying wind and solar power technologies from the domestic user to the corporate market. There has been a dramatic improvement in the efficiencies in these technologies and this has helped make the applications economical. Specific energy yields from wind turbines have increased by 60% and installation costs have dropped significantly (up to 50% in many cases). Global wind generating capacity has reached 100,000 MW capacity in March 2008 with almost 20,000 MW installed during 2007 alone.
Applications of photovoltaic (PV) systems are growing rapidly worldwide with worldwide installation of PV modules skyrocketing to 2,826 MW in 2007 (= 62% growth from 2006). Many countries are passing legislation to enforce greater use of PV systems and this is helping to drive up the production of these systems.
All of these technologies are interdisciplinary requiring a knowledge of topics as varied as aerodynamics, electricity and wind statistics for wind power and mechanical engineering, electronic and electrical engineering for solar power.
This workshop will outline the step by step process of designing, installing and commissioning photovoltaic and wind powered systems. It should be emphasised that this is not an advanced in-depth workshop but one covering the important issues enabling you to do simple designs and then to investigate the design and installation issues in more detail after the workshop either by further study or in conjunction with experts in the field.
In recent years the annual growth rate of the solar and wind energy industry has consistently exceeded 30% with 3 digit growth figures in many regional markets. So in these rather challenging economic times; this is a good industry in which to focus one’s career on.
WHO SHOULD ATTEND?
Control and instrumentation engineers
Electrical engineers
Electricians
Electronic engineers
Energy specialists
Facility managers
Mechanical engineers
Technicians
…and those who are keen to improve the environment and take advantage of cheap and clean power.

Heat
• Heat = thermal energy • can be converted into other forms of energy
Technology Training that WorksTechnology Training that Workswww.idc-online.com/slideshare
Conversion of units
1 kilo joule = 1 kilowatt-second
= 1 / 3600 kilowatt-hour
= 2.7 * 10 –4 kilowatt-hour
1000 kilo joule = (2.7 * 10 –4 ) * 1000
= 0.278 kWh
or:
1 kWh = 3.60 kj

Laws of Thermodynamics
• First Law of Thermodynamics and Energy Conservation
Energy can neither be created nor destroyed
Whenever energy is transformed from one form to another, the total quantity of energy remains the same
Technology Training that WorksTechnology Training that Workswww.idc-online.com/slideshare
Energy Conversion Process
E1 + Qa – Qt = E2
– E1 - energy possessed by the system initially
– E2 - energy possessed by the system after the work is done
– Qa - energy added to the system
– Qt - energy taken away from the system
Technology Training that WorksTechnology Training that Workswww.idc-online.com/slideshare
Second Law of Thermodynamics
• Heat flows from a body at higher temperature to a body at lower
• Work has the tendency to convert into heat
Technology Training that WorksTechnology Training that Workswww.idc-online.com/slideshare
Renewable energy
• Energy, which is continuously replenished by natural processes on the earth
• Solar energy
• Wind energy
• Hydro energy incl. Tidal & Wave energy
• Biomass/Biogas
• Geothermal energy
Technology Training that WorksTechnology Training that Workswww.idc-online.com/slideshare
Non-renewable energy
• Energy resources with finite reserves,
that cannot be renewed within our lifetimes
- fossil fuels, e.g. oil, coal, natural gas
- Nuclear fuels, e.g. uranium

Economics of scale
Example:
Capital cost (capex)
small to medium size
Wind Turbines

Economics
Payback period (in years)
Total Initial Cost
= -----------------------------------------------------
Annual Cost Savings - Annual Operating Cost

Other economic factors
• Increase in energy costs relative to general inflation
• Interest paid on borrowed money
• Insurance cost
• PR opportunities
• Grid feed-in tariffs
• State and federal funding programs
• Assets resale value

Driving Forces
• Reduced environmental impact
• Energy independence and diversification
• Inflation-proof fuel costs
• Direct + indirect costs of fossil fuels
Technology Training that WorksTechnology Training that Workswww.idc-online.com/slideshare
Cost of energy per kWh
Annual Cost = Capex/Service Life + Opex
typical Service Life 20 to 30 years (wind & solar)
•Step 1
•Step 2
Cost / kWh = Annual Cost / Annual Energy Output

energy is the one
that we don’t use”
