Producing heat through oil combustion or electricity is an expensive way for a home heating. There is a second choice for heating a house, it is solar energy. It is an alternative and cost effective energy and affordable for everyone. In this essay you will learn about, how to provide both solar heat and domestic hot water system to our homes. A low cost ‘DIY solar heating panels can be benefited if we use it practically. Now we will discuss in detail.
For Your Information:
In the day time, sunlight remains throughout the day for 12-hours. It means that it is available in maximum time than the fossil fuel reserves. Many people put off their solar collectors and PV panels, because they are much costly or they are unreasonable for the neighbors. Now the good news is that solar thermal roof may no longer be an issue in today energy market. It is affordable and cost effective and it is no more effect the aesthetes. The renewable energy house is designed for the small plant. PV application can supply the power and solar thermal application can supply the heat.
Both these applications supply energy according to the household requirements. A 5k PV system cost is about $ 50,000 and 10m² and domestic solar hot water system may be $10,000 if it is professionally installed. But the PV payback status is longer. Other DIY home heating DHW system cost $2000. If you need to build your own solar thermal system for your home then first of all you should know about the basic knowledge about it.
Features for Homemade Solar System:
Glazing materials research:
There are many variety of glazing materials available in the market today with different properties and cost. This interactive research exercise is designed in helping to clarify the properties and cost about the glazing materials. But this information is in complete, it is just a raw material, but actually is a beginning.
Glazing materials experiment:
In the given experiment, it is require testing the heat gaining ability of a different glazing material. If you can’t understand you should go to the next step.
Hot Box:
Build two solar boxes for solar thermal experiment which display the greenhouse effect. Paint both the boxes inside, one with a black and other with a white. And place them in the sunlight. Consider closely the temperature of both the boxes; draw the result on the graph paper. And explain why one solar box gets maximum heat against the other, and continuously use different materials in the same manner.
Concentration:
In this step we will construct and test a parabolic trough solar concentrator and parabolic dish concentrator. Parabolic dish concentrator can produce higher temperature against parabolic trough concentrator. And explain what is the merits and demerits of parabolic trough concentrator with a tracking devices? Why it is not popular? Define heat?
Window Box:
This is a great, simple experimental project that how we provide more heat during the extreme cold. It is information about a passive, thermo-siphoning, heat transfer system. It is not information regarding heat gaining project. It is a nice starter project for the ‘novas’ Mother Earth news has published wonderful article that in what way we call the heat grabber. It is a very useful project of solar heating according to your requirement.
Solar Energy Gain:
You should design and construct such a green house which obtains heat directly from the sunlight. Sometime a solar energy is only used to maintain heat in the green box so that we protect the plants in winter season from the extreme cold. Anyhow you should take temperature record of the greenhouse with or without heat storage. And explain the importance of your findings and testing.
Heat Loss:
The system which obtains heat directly from the sunlight has maximum energy loss. For the experiment you need two cups, one is ceramic and other is Styrofoam cup. Pour some water in the ceramic cup and place it on the fire for boiling. After ten minutes of time, measure the temperature which will have been fell within 10 minutes. Repeat the experiment with the other cup of Styrofoam. Now place a lid and record the temperature of Styrofoam cup, can you estimate the R-value of both the cups from your data? Lastly display your conclusion after the completion of your experiment.
Heat Storage or Accumulation of Heat:
There is a discontinuously property exist in the nature of the sunlight. So because of this, it require a means of storing of heat, so that we use it according to our requirements. This exercise is designed to introduce a few heat storage systems so that you can construct it and take experiment of them. We will be highly appreciable by the student’s participation so that they may also make some ideas. We adopt the exercise so that we introduce alternative method of heat storage.
Trombe wall:
To construct a different applications such as a ‘working passive solar heating, modified, Trombe wall. After the building up of all these applications, observe and adopt such procedure that we provide heat to the house without losing the preserve heat for the night.
Solar Greenhouse:
Take a temperature measurement from time to time inside the greenhouse and trace the convective current which clear the way for its circulation inside the greenhouse.
Batch Heater:
A bread box be composed of direct-heating, direct gaining, passive solar hot water tank. The hot water accumulated in the tank for the purpose of preheating the household water. For the experiment prepare the bread box solar hot water heater, after the build up collect the data and explain the merits and demerits of this solar hot water system.
Solar Collector:
Construct experimental solar collector and display how solar hot water can be prepared. This project is sufficiently more advanced and the cost expenditure will be more on labor and it will also need more expenditure.
Radiant Floor Heating:
Prepare a model of a radiant heating system. Explain why radiant heating is used for solar heating systems.
Solar Home Design:
Make a model of energy independent house. Explain how many collectors you need in this regard. What is the size of the multi tank heat storage vault? How many PV panels you need for the system. Also calculate the heat gain/loss of the house.
Solar Thermal Roof:
Build a scale model of a house with a solar thermal roof. Calculate how much fuel oil energy it will save in a year.
Solar Thermal Engine:
Make a design of the solar thermal engine and combine it in the design of the solar thermal home.
Solar Hot Water Systems:
Batch heater, drain down, drain back, trickle down, and closed loop are included in this system.
Plant Bed Heating:
A method of storing greenhouse heat where it is needed most in the plant bed so that the plants are nourished.
First MTD Collector:
It is a learning experience.
Trickle Down Solar Heating system:
An exclusive, cost effective, home heating, domestic hot water system DHW is designed for the DIY purpose.
I hope this useful course in solar thermal energy technology will be effective sufficiently for help. World oil production is going greater now before this but it is must be kept in mind that the oil well are decreasing and production will be slow down if the situation remain the same as such. Unfortunately the demand for the low cost energy is continuously rising. So if this condition still remain then which way do you adopt which is reasonable than oil certainly, it will be a solar energy an MTD system.
