The cost estimation of the present invention is as shown in the table：
1 cost estimation of table
Since the present invention is all made of simple part and ripe component, without complicated technology and rare material, therefore at
This is cheaper.When the present invention is used as domestic solar water heater, cost is about 3200 yuan, with the height in consumer goods market
Hold the cost of brand solar water heater suitable.
When the present invention is used as enterprise's solar chp system, compared with the cost between photovoltaic power station as
Under：
According to National Energy Board's publication on the 13rd of September in 2016《National Energy Board demonstrates about solar energy thermal-power-generating is built
The notice of project》, the system transfer efficiency of 7 slot type photo-thermal power stations is differed from 14.03% to 26.76%, it may therefore be assumed that too
Both positive energy cogeneration system is equal with the system transfer efficiency of photovoltaic power station, need to only ensure when calculating cost
Light harvesting total amount it is identical；
An article according to rope than photovoltaic net (solarbe.com)：《15KW photovoltaic power stations Project design, at
Originally, income detailed annotation》, it is known that the cost of investment of 15KW photovoltaic power stations is 11.25 ten thousand yuan, and average annual energy output is 1.72 ten thousand
kWh.The project crystalline silicon component of 48 pieces of 315W, it is about 96 square metres that thus can estimate light harvesting area；
The steam turbine Economic and Efficiency Analysis of Zibo Shen De steam turbines Co., Ltd of small steam turbine leading enterprise
(https://detail.1688.com/offer/1168332456.html)：
" three, careful moral steam turbine performance analysis
1,6.5 tons of Industrial Boilers match 320KW back pressure type steam turbine generating sets
1., 24 kilograms of boiler pressure, 390 DEG C of temperature.
2., 3 kilograms of process steam pressure, 130 DEG C of temperature, when production can often generate electricity 1 degree with 14 kg of vapor.
3., production per hour use 5 tons of vapour, can generate electricity per hour 330 degree, daily power generation 8000 degree.
4., it is annual press 300 days, whole year can generate electricity 2,400,000 degree.
5., often degree electricity by 0.50 yuan calculating, whole year can 1,180,000 yuan of power cost saving.
6., 6.5 tons of boilers, whole year uses 240,000 yuan of coal, 60,000 yuan of labour cost, 60,000 yuan of overhaul to add up to 360,000 yuan, therefore can obtain in year
840,000 yuan of net income.
7., the project investment amount to 600,000 yuan (500,000 yuan of equipment, other 100,000 yuan), current year recoverable investment.“
On this basis, it is calculated within 8 hours according to daily Operation at full power, the year power generation of this set 320KW Turbo-generator Sets
Amount is 93.44 ten thousand kWh, is equivalent to 93.44/1.72=54.33 15KW photovoltaic power station.54.33 a 15KW is distributed
The light harvesting area of photovoltaic plant is 96*54.33=5215 square metres, and cost is ten thousand yuan of 11.25*54.33=611；
Using table 1 model when, price of the invention be 0.4 ten thousand yuan.Since the present invention can be from the motion tracking sun, light harvesting
Efficiency improves 30%, thus total light harvesting area need to only reach 5215/1.3=4012 square metres can be with photovoltaic power station
Light harvesting total amount it is suitable, i.e., totle drilling cost be ten thousand yuan of 0.4*4012/2=802.Along with 600,000 yuan of (photo-thermal of Turbo-generator Set
The cost of preheater, evaporator, superheater and pipeline road in power station approximate can be replaced with boiler cost), container body 10
200,000 yuan of ten thousand yuan and pipeline road, it can be deduced that the cost of 320KW solar chp systems is about 8,920,000 yuan.
The cost for being apparent from the latter has been higher by 46% than the former.Hot water, steam can be provided simultaneously and stablize adjustable as a set of
The multifunction system of electric power is spent, cost only increases 46% compared with the photovoltaic power station that can only be generated electricity, and competitiveness is suitable
It is powerful.Moreover, the present invention also has following three points advantage：
(1) cost is calculated according to domestic solar water heater's model of table 1, and light harvesting area only has 2 squares
Rice, if selecting the model for being exclusively used in solar chp system of volume bigger, totle drilling cost can be lower；
(2) industrial chain of photovoltaic power station is quite ripe, and the present invention has just been in the budding stage, with production
The maturation of industry chain, cost of the invention will become closer to photovoltaic power station；
(3) when the present invention squeezes into consumer goods market and industry and commerce market simultaneously, an industrial chain is only needed.Therefore, yield carries
Rise faster, industrial chain maturation faster, cost decline faster.
In conclusion when as domestic solar water heater, existing product is compared, the present invention has the following advantages：
(1) can be with the active tracing sun, collecting efficiency is higher by 30% or so than existing product, therefore collector area smaller,
Lower, the annual collecting efficiency of installation requirement remains at same level；
(2) incrusted problem has not existed in vacuum tube；
(3) volume will not expand when conduction oil solidifies, so there is no explosion hidden danger when severe cold area is used；
(4) appearance is more good-looking.
When as enterprise's cogeneration system, photovoltaic power station is compared, the present invention has the following advantages：
(1) have heat storage capacity, peak load regulation network can be participated in, generated electricity by dispatching of power netwoks, be solved perfectly " abandoning light to ration the power supply "
Problem；
(2) have cogeneration ability, energy utilization rate higher (80% or more), profit space bigger；
(3) generating efficiency will not reduce year by year.
It is then had the following advantages compared to photo-thermal power station：
It can be built to adaptation to local conditions in occasions such as cell, school, hotel, factories, do not need sheet of smooth location, advise
Mould is changeable, and the scope of application greatly improves.
The present invention overcomes the shortcomings that existing solar water heater, photovoltaic generation and photo-thermal power generation well, is new one
The solar utilization technique in generation.
