How to Solar Heat:
Oil heating is an expensive way for a home heating. There is a second choice for heating a house, it is a 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.
In our first step we will learn about, how to construct a homemade solar collectors from recycled materials. We need the procedure that how we take more advantage from the available scarce resources, so that we can be capable of transition from an oil based, waste economics to sustainable sun energy based social order, where basic needs of human being are essential against Gross National Products (GNP, means the value of output produced by domestically own factor of production).
To energy independent, it is not the entire solution of our social and economic problem, but to the little extent it can, if we take a better use of solar energy we will be more sustainable in position. There are a few houses that are benefited from the solar energy applications, but these few houses can take more advantage from the solar energy. When we construct a house we must kept in our mind about the facility of solar energy. Change is possible with a little determination.
As a human being, we have the ability to clearly understand the nature of corporate greed, unchecked and unrestrained capitalism and disastrous runaway of global warming. We must not be careless from these social disorders. We are the guardians, a protector of Space-Earth. We have the responsibility to settle limitation and prescribed suggestion that how to check the capitalism and in addition to find alternatives to the fossil fuel which are destroying our planet. How shall we provide heat to our homes? As Thomas Edison said in 1939, “we are like tenant farmers chopping down the fences to find our houses when we should be using the energy from the sun”.
As we mentioned earlier that a solar energy, or a DHW system is not a solution of our social and economic issues, but it is the right direction to get advantage from the sunlight. Million of years are requiring transforming deteriorating micro organism in to oil, and unfortunately we have already consumed half the Earth supply or resources. Low cost affordable, PV panels, active/passive solar heating system, solar green house and many more as such useful materials make all of us energy independent.
Solar cats like Harmony Cativan, left, stay warm by seeking sunny places. Regrettably to say, that the people commonly use the petroleum products to get warm, because of this excessive use of petroleum oil resources are now decreasing day by day. And it is not right way to chose, it diminishes the value of our earth. People consume 100,000,000 barrels of oil in a single day. The excessive use towards such energy is reached to the critical level. Non renewable resources are burned. It should be recycling to prepare products such as plastics, paints and other useful and valuable products. Because of the burning of these non renewable resources the air is filled with toxins. There are various diseases have been produced, and also increasing in numbers, such as ‘asthma’ the result is death.
Global warming is another huge environmental issue. A well insulated house with a properly oriented array of solar collectors is a useful and fruitful idea and settlement against this drastic situation. It is a clean and cost effective alternative to the environmental disastrous of fossil fuels.
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 are 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 today energy market, it is affordable and cost effective and it is no more aesthetes just remember that the beauty is in the eye of the beholder. The renewable energy house is designed for the small planet. PV application can supply the power and solar thermal application can supply a heat. Both these applications are 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 applications such as DIY home heating DHW system for $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.
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.
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?
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.
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 is exist in the nature of the sunlight. So because of this, it necessitates 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.
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.
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.
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.
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.

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 solar energy an MTD system.
