Some informations of Sun
Sun exists for over 5 million years
Sun is 150 million km far away from us
Energy of solar is 20,000 times than the energy we consumed in 1 year
20% of solar energy is stored in cloud and atmosphere
50% of solar energy can penetrate atmosphere and arrive earth which will give us warm to survive. It will be the reason for the wind and tide
The consumption of solar energy in 1 year will be equal to the 157 times of coal storage and 516 times of oil storage
.
Where we use solar energy?
The system cater for hot water required to Otels, homes, workplaces, public buildings, student-residences, schools and spor saloons in summer %90, in winter %50. The fuel quotation decreases proportional hot water that is used. The system compensates cost-price itself in two years.
The sun-beam that arrives to world, is 5000 times more than need. Capitalizing on this great energy is the most important researching subject in these days.
The sun provide both to saving energy and ecological-balance.
Natural Circulation System
Natural Circulation System which is both closed and opened circuit system is unneeded any pomp from tank to collector, works by hot ant cold water changing place. The system works like this; the water that is heating, becames rarefy and moves up. Cold water which isnot rarefy, moves Upside to down.
Kinds of Natural Circulation System
• Pressure system (Pressure hot and cold water)
• Vertical tank system (nonpressure hot and cold water)
• Horizontal tank system (nonpressure hot and cold water)
•Closed circuit
Algebraic Circulation System
Algebraic Circulation System which is both closed and opened circuit system is needed a pomp from tank to collector, works by hot ant cold water changing place. The collector is placed up than tank in this system.
The system works like this; water that is heated in collector, stays in collector because the collector is upside. Moving down hot water is used a pomp. It is pomped up the water and hot water moves down prom curculation horn so it arrives the boiler and heats the water in.
Kinds of Algebraic Circulation System
•Duble antigorite system
Individual
Industrial
•Single antigorite system

Solar Energy Saving Price
A family (4 people) expend 50 lt x 50°C hot water for a year. If mains water is nearly 12°C, to provide hot water which is needed;
A = mxcxdt
M = needed hot water for a day (50 It. x 4 people = 200 It.)
C = 1
DT = T1 - T2 (difference between needed water and mains water)
@ = 200x1x38°C
@ = 7.600 kcal/day
@ = 2.774.00 kcal/year
