1. Introduction
Solar cookers in which the cooking pot is placed at the focus of a concentrating mirror but they
have not been widely adopted because we have to continually adjust the orientation of the
concentrator so that the food can be cooked.
If we also take a look over Hot box ovens and concentrating solar cookers we can find that they are
cheap and effective; however they are limited to cooking during clear sky periods and they also
require the cook to work outdoors.
These are the main components to most solar cookers:• Concentration (reflection, or reflectance)
• Absorption (ability to attract or hold heat.
• Retention (means or capacity to retain heat)
Advantages:• There is no fuel requirement and no recurring charges
• It also maintains quality of food cooked
• It also retains the nutrition value of food
• There is no soot formation
• No health problem because there is no smoke is formed while cooking.
2. Motivation
1. India National Solar Cooker Program 1985-1986
2. ATDO Project In pakistan
3. GTZ Solar Cooker Project In Mali 1979/80
4. GTZ Solar Cooker Project In Kenya
5. Chinese Solar Cooker Development Program
6. The Yurt Project In Europe in 2006
3. Objective
o The food can be cooked at any time of day
o The cooking method should also be similar to conventional cooking systems so that it doesn’t
prove to be a hurdle while cooking.
p There should be minimum change in appearance of cooking appliance.
q Reducing any conventional sources of energy also serves an important objective.
4. Contribution
There are three main components to most solar cookers
a. Concentration (reflection, or reflectance)
b. Absorption (ability to attract or hold heat.
c. Retention (means or capacity to retain heat)
System Description
The primary elements of the solar cooking system are:
• High temperature solar collector consisting of a non-tracking concentrator with evacuated
tubular absorber.
• Passive downward heat transport system to transfer energy from the solar collector to the
energy store.
• Thermal energy storage unit along with the conventional energy backup.
• A energy transfer system between the store and the cooking surface. Conventional hot plate
surface modified to work with thermal energy input and overall doing a better job.
Sustainability assessment of home-made solar cookers for use in developed countries:-

TOTAL ELECTRICAL COMPONENT COST = 17 076 INR OVERALL COST OF THE SOLAR COOKER = 24
589 INR
ENERGY GENERATION BY A SINGLE SOLAR PANEL
• Average annual solar radiation in India per day = 23.4 MJ/m^2 (H)
• Total area of the solar panel = 0.45*0.35 = 0.1575 m^2 (A)
• Cell conversion efficiency = 16% ( for a 30W solar panel) (r)
• Performance ratio (conventional ratiowhich includes all the losses associated to the solar panel)
= 75% = 0.75 (PR)
Energy generated by a solar panel per day, E = H*A*r*PR
= 23.4*10^6*0.1575*0.16*0.75
= 442260 J/ day
VALIDATION
Conventional Solar cooker based
ØMaximum temperature attainable by conventional solar cooker = 165 °C ØMaximum temperature
attainable by the designed solar cooker = 270 °C
Reflective Heating based
Ø Maximum temperature attainable by parabolic dish cooker = 290 °C ØMaximum temperature
attainable by designed parabolic dish cooker = 327 °C ØMaximum temperature attainable by
reflection by solar panels = 178 °C
From the above results mentioned, it can be concluded that the designed solar cooker is more
efficient and effective than the conventional cookers
COMPARITIVE COST ESTIMATION
+Gas Stove Charges + Regulator = 5000+500 INR
+Gas Charge 5 MJ 2 Hours Per Day Monthly = 1500 INR +Total Gas Charges For Year = 18000 INR
+Total Charges For LPG Gas Cooking In A Year = 23000 INR +Total Cost in constructing a Solar
Cooker = 24589 INR
+From the above Data about the cost of other cooking methods, it can be depicted that the cost of
solar cooker is marginally higher.
5. Contribution
• Comparitive analysis of different standard solar cookers from box,parabolic,panel.
• Sustainability check of home-made solar cookers for use in developed countries with different
projects.
• To meet the best suitable design innovation of solar cooking andlimitations in the current trends
and how to overcome such disrupt.
• Elephant test results, heating performances of various types of solar panels.
• Deflection angles of solar panels with varying solar angles hroughout the day in python.
• Design and electical components cost estimation for final design.
• Energy generation by a single solar panel and comparative analysis with our final design.
• Comparitive cost estimation and validation.
6. Conclusion
Scientists all over the world have made large number of efforts in developing different types of
solar cookers for many decades. Although it can be one of the best alternative for cooking, it is
hardly accepted by the society.
There are many reasons for that like lake of awareness, large size, bulky models, slow cooking,
highly dependent on weather conditions, fixed cooking time etc., Our solar cooker design can work
for all time and can cook faster than the conventional solar cooker has being designed and
developed which if commercialized can become competent to the conventional solar cooker and
can be proved as a boon to the society.
