Now you can power your house with green energy. It may sound expensive or difficult to convert normal home into sun-inspired home. But in fact, it is fairly simple and economical. These have countless benefits. Being environment-friendly, these are safer and not harmful for the atmosphere around.

Two methods of solar heating are “active” and “passive”.

Active solar heating

Specific equipment is required for active solar heating. Pumps and fans are needed to move or direct sun heat. There are two further classifications in it, which are air-based and liquid systems.

1.Air-based solar heating

In air-based solar heating systems, collectors are used. These trap air which absorbs and transfers heat from the sun. Air-based system can work on lower efficiency than liquid ones. Why is that so? The reason is that air cannot transfer heat efficiently like water can do.

Advantages of air-based solar heating

There is an advantage of air-based solar heating that these systems can warm up room directly. These can also function early in the morning and late in the day. Moreover, these are easy to build and install. These can be fixed outside so that more than one room in a house can be heated.

Air-based connectors are mostly installed on window frames, roofs and walls.

2.Liquid-based active solar heating

Liquid solar collectors are used in liquid-based systems. These trap and move heat. Most common are flat-plate collectors. A fluid, like water or antifreeze is filled. This liquid absorbs heat. This heated fluid is then transferred to heat exchanger or storage tank through mechanical collector such as pump.

Important considerations

While installing solar heating system, consider these important things first:

  • Its cost is affordable
  • Size is suitable to your particular needs
  • It is durable and long-lasting
  • Tank placement is absolutely accurate

When entire mechanism is properly installed, solar heat can be distributed with a central-forced air system, a radiant floor, and a baseboard or hot water radiator.

Passive solar heating

Another type is Passive solar heating system. It works by storing solar energy. It does not require any electrical or mechanical devices.

Solar energy systems are considered as the best alternative to the traditional ones. Solar energy is being converted into other forms of energy pretty successfully now-a-days. This is one of the most reliable and efficient thing to do. You are not required to spend a lot of money on fuel anymore. All you need is sunlight.

Applications of solar energy

Applications of solar energy

Solar energy is available all over the world, and you do not have to pay for it unlike other sources of energy. The function and efficiency of the devices that run on solar energy depends upon the amount of sunlight they are subjected to for the entire day. Lighting and heating are two of the most significant applications of solar energy systems.

Passive solar gain

If you are interested in getting a solar energy system for your house, you are recommended to get quality parts like solar panel, battery, etc. When it comes to heating, direct gain is the simplest technique regarding passive solar gain. You must be aware of the fact that the passive solar heating does not require too much maintenance. In fact this sort of heating needs the minimum amount of maintenance as compared to other techniques.

Active solar gain

On the other hand, the active solar heating totally relies on the mechanical devices for the transfer and distribution of heat, which makes it obligatory for the person to maintain the components well. Read the full story

In most heating systems gas furnaces and liquid boilers are used while in some homes active thermal heating systems are also being used. Furnaces directly heat the air for space heating and in boilers radiators, radiant floors or baseboard radiators are used for heating the water or any other liquid. These radiators can be thermally or electrically driven.

Usage of solar and geothermal energy

Usage of solar and geothermal energy

The upcoming technology for space heating is active solar heating system and geothermal pumping systems. The thermal heating by furnaces and boilers are the least efficient methods. Solar and geothermal heaters have low power the maintenance coast of these heaters is very low. Now there advancements have been made in the traditional heaters and more efficient models of those heaters are available and they have the inability of competing with the solar and geothermal heaters.

New efficient models

The classic models are more inexpensive than the new ones but the new models are more energy saving and have better durability therefore, these models are preferred by the consumers. The active thermal heating systems are classified on the basis of their driving force that is mainly gas, solar and geothermal. Read the full story

There are mainly two ways of solar heating, those are active and passive. In passive solar heating process there is no electrical or mechanical device to gather the solar heat. This whole process is done by using the structure and design of the buildings, and is considered advantageous due to low maintenance and operational coast. While in active solar heating pumps and fans are required to direct and move solar heat. Active solar heating is further classified into air-based and liquid- based systems.

Liquid-based active solar heating

Liquid-based active solar heating

To trap the solar heat and in moving it liquid-based solar systems use liquid solar collectors. These collectors are filled with the fluids; the fluids are used on their capability of absorbing solar heat. These fluids can be water or any antifreeze agent. Flat-plate collector is among the most common collectors which are being used.

Working and installation of liquid-based solar systems

Mechanical collectors are also used; pump is a common mechanical collector it is used in transferring the heated liquid into heat exchanger or storage tank. If you are planning to install this system you have to decide about the size, coast, placement and durability of the storage tank. The distribution of the solar heat can be done by central forced air system or using various type of devices.

Air-based active solar heating

Air-based solar heating system uses air instead of water for transferring solar heat. The operations of the air collector are less efficient than the liquid collector. The main reason for lesser efficiency is that air does not transfer heat efficiently than as liquid. Read the full story

If you want to understand solar heating then first you have to understand the basic things about solar things and the types of solar heating.

Types of Solar Heating

Types of Solar Heating

There are basically two distinct types of solar heating. One is active solar heating and other is passive solar heating.

Active Solar Heating

Active solar heating uses fans or pumps for functioning and to direct solar heat. The method of active solar heating is further broken down to air and liquid based systems.

Passive Solar Heating

It collects sun energy without the help of any type of electrical or mechanical devices. It is mainly down through strutting and building designs. This method is beneficial for its low maintenance and operation costs. Following is the useful information about passive solar heating method.

Material Structure and Orientation of Passive Solar Heating

Passive solar heating is enacted through the material structure, design concept and orientation of a home or a building where it is used in relation to the sun. This method is implemented at the time of initial construction of home.

Structuring and Designing of a Home

Active Solar Heating

Active solar heating main purpose is to use the solar cells to collect and absorb solar radiation. The radiation is converted into heat by solar cells and then its transferred to the interior of the building. Active solar heating works in two ways.

Solar Power System Home Use

First way is through solar liquid heating. Solar heating usually warms water or antifreeze through the use of solar cells. Then the liquid is pumped into home and heats it via radiators. In some cases same method is used to heat pools.

Second method of active solar heating is solar air heating. Solar panels warm the air then that air is pumped into home through a forced air pump. Active solar heating systems are usually designed in such that that they meet 40 to 80 percent of a home’s heating needs, as less than 40 percent is not cost effective and more than 80 percent usually requires the use of too many solar cells.

Passive Solar Heating

Warming the building by using natural sunlight is called Passive Solar heating. Homes that use passive solar heating usually have large windows facing southwards. The home which use passive solar heating they are well insulated and often have overhangs over the windows to keep the home cool when sun is at its highest. Passive solar homes also take advantage of insulated curtains and windows to minimize heat loss.

Solar Electric System

To absorb solar radiation a solar electric system uses photovoltaic cells. These photovoltaic cells are semiconductors. Electrons are loose out when the cells absorb sunlight this is called photoelectric effect. Then free electrons move to circuit where they form an electrical current. Cells are connected to form panels and each panel creates 10 to 300 watts. Usually a building or home haves several panels for its power supply. The panels are fixed in a specific angle, or panels are having tracking device to maximize power for a day. Solar panels can stand-alone or can be hooked up to the power grid. There several solar array systems in the southwest that supply the electric grid.
