Solar Swimming Pool

Shallow water in a pond or lake tend to be more heat than the water that is in a deeper place. This occurs because the sun can warm a basic pond or lake in the area that is more shallow, and that means water that is above become hot.

With the same principle, the sun can be used as a water heater in the building and swimming pool. Most of the water heating system that uses the sun as a source of heat, consists of two main parts: the sun collectors and storage tanks. Collectors that are commonly used flat plate collectors. Collector consists of thin flat box with a transparent top cover part and facing towards the sun. Small pipes that is in the box bring liquids, which can be water or other liquids, to be heated. Pipes is paired on the black plate that serves to absorb heat from the sun. After a heat form in the collector, the liquid is in the pipes will be hot.

Home Sweet Solar Home – Making Homes Better With Solar Technology

Executive Summary about Solar Home by Anne Clarke

By now many people know it is possible to generate energy without the use of dwindling traditional resources. This stimulated atmospheric cycle is the product of a solar biosphere that remains in constant, gradual motion. You can draw energy directly from the sunlight, you can save money on energy costs, and you can be a big part of the effort to protect our planet. Remember, though, solar panels are not the only type of solar technology available that can harvest a decent alternative to electricity from the sun. There are wind turbines, solar panels, biospheres, and many other innovative solar power mechanisms that have made headway in an extreme scientific objective to help protect the earth. Despite what many people might believe, there are solar solutions available as alternative energy sources that virtually anyone can choose over electrical energy. Soon construction companies for homes, office buildings, apartment complexes, and more will adopt new methods of design that will dovetail more easily with solar technology.

Solar Energy Applications

Solar energy technologies use energy from the sun to produce heat, light, hot water, electricity, and even cooling, for homes, commercial and industrial.

There are a variety of technological applications that have been developed to take advantage of solar energy. Technology can be read further below.

Photovoltaics System

Solar cells work by converting sunlight directly into electricity. The electrons in the semiconductor material, the material used to capture sunlight, will move when the sun’s energy in the form of photons hit it. Solar energy is forcing the electrons to move, occur continuously, and consequently there is also a continuous electricity production. Process, which turns sunlight (photons) into electricity (voltage), called the photovoltaic effect.

Solar Cell Module

Solar cells are usually organized into modules that each module can consist of 40 solar cells. Some modules can be arranged to form a PV line fitted with a fixed angle facing south. Or even could be placed in a sun-tracking device, to get more solar energy throughout the day. Several rows of PV could produce enough power for a house. As for industrial applications or power companies, hundreds of lines of PV can be linked to form one large PV systems and sufficient to meet the electricity needs.

Thin Film Solar Cell

Thin film solar cells use several layers of semiconductor material with a thickness in the micrometer scale. Technology allows to create solar cells integrated into rooftops to the skylights. Even solar cells are designed for applications having the same power with actual roof.

Active and Passive Solar Heat

Utilization of solar energy in architecture can be done in two ways: passive and active. Utilization of passive do when solar power does not need to converted first into electricity. Deep utilization of the passive is also included on space heating (using the greenhouse gases) for the region with temperature of the air low, and water heating. Also, techniques to prevent heating the air in the room on the building in the area, including Tropical into the use of the passive type, where component of sunlight, which consists of: light and heat, only used on components’ light ‘it – the need for natural lighting in buildings.

Passive design strategies will be very different between the buildings that are on climate Tropical and climate Sub Tropical / cold. At the Tropical climate, direct radiation from the sun tend to be avoided by building in order to heat gain in the building to be low, so the increase of air temperature in the building can be prevented. While in Sub-Tropical climate, the design strategy is a passive step of the Tropical climate strategy in the acquisition of heat sun tend to be maximized (except in the summer), solar radiation through that fall directly on the building so that temperature increase occurs in the building, considering the air temperature around is low.

In utilizing the solar actively using the photovoltaic, should also simultaneously architect implement the strategy of passive design. Without the application of passive design strategies, energy use in buildings very likely remain high when visual and thermal comfort must be achieved. In situations such as this, the electric power comes from solar power conversion by solar cells does not become too much meaning. With dimensional solar cell panel which needs large electricity for the achievement of thermal comfort and visual on the building difficult to fulfill. Still electrical energy required for engine cooling air with a large capacity, because the air temperature in a high building, also required electricity for lights in the torch-lighting building a dark room when the strategy passive design that lead to the energy savings are not applied. Role of solar power to replace electricity necessary to achieve the building comfort (thermal and visual) finally failed because the building was not designed in such a form so that comfort achieved without the many electric energy consumption. Electricity generated by the photovoltaic possibility will not be large enough to cool down and illuminate the building. In other words passive design considerations for the use of energy in buildings in this case can not be ignored.

In the passive design, objectives of architecture work that would be achieved – that is comfortable and aesthetic, are generally made integral. Each step in the preparation of the components to form the jacket, simultaneous will result in the achievement of buildings comfort and aesthetic. Be not so with the case where the design of active solar cell panels can be arranged separate components with the preparation of building casing. In other words, the achievement of building aesthetic in active design done in a more flexible and separate with the strategy of comfort achievement, although in fact the architects are required to thought to integrate a comprehensive comfort needs with aesthetics – between needs using a solar cell panel with place them on the integrated shroud of the building so that the panels at once can be a building aesthetic element.

The High Costs of Solar Electric Power

Executive Summary about Solar Electric by Klaus H Hemsath

Promotion of solar power generation is booming. Why are solar farms built when financial data clearly show that solar power is still the most expensive electricity generation technology available?

Solar power plant developers and marketers obviously know that they need to lower costs. Cost reduction is, however, expensive and takes time. There are two major technologies for solar energy conversion. Electricity production with steam is a very mature technology. The other technology is the direct, photovoltaic conversion of sunlight into electricity. This technology will most likely become the dominant solar electric power generating technology – eventually. The concentrated sunshine creates very high surface temperatures on the solar panel. To save solar panel area and make the solar panel price competitive, one must cool the surface of the solar panel very efficiently to prevent it from melting and destruction.

Present production costs for generating electricity with solar panels are hovering around $0.50 per kWh. Right now, solar power does not yet make economical sense.

None of the available technologies using renewable energy can compete with the cost of electricity generation from coal.

The technologies for generating electricity with solar power, wind power, marine power, and geothermal power are very well understood. At present, a respectable number of windmill farms and solar panel farms are being installed. Solar power does not make economical sense, yet. A random sampling of recent announcements of solar farm installations reveals that system installation costs are in the $3000 to $7500 per kW installed capacity. These plant costs loosely translate into a cost of producing electric power at $0.30 to $0.60 per kWh. This very unfavorably compares to the cost of electricity generation by any other technology.

As long as solar power constitutes only a very small fraction of overall electric power generation, the additional costs of storing intermittently produced electric power are not yet of concern. If the US is going to depend significantly on the intermittent production of electricity from solar power and wind power, it must begin to develop storage technologies for huge amounts of electric energy. Intermittent, renewable energies and electric energy storage are inseparable.

The Solar Electric Panel – An Inexpensive Way to Generate Electricity
Executive Summary about Solar Electric by Dan A Swanson

The solar electric panels, generally called solar photovoltaic panels, are made of a set of treated silicon cells arranged in a series array. They produce electricity on being exposed to the sunlight. A small solar electric panel will lessen the energy bills considerably, while a big solar panel will in fact budge the meter backwards. The contemporary solar electric panels are simple to install and are modular. The solar electric panels transform the sunlight to DC (direct current) electricity. Buy any of these solar electric panels according to your requirements.

Solar electric panels are the perfect answer to our increasing electricity bills and ever increasing reliance on depleting conventional energy resources. Make a one time investment in solar panels and generate free electricity for years to come. Solar electric panels are the need of the hour.

Solar House Plans – The New Wave Of Our Future

Executive Summary about Solar House by Ernest Jarquio

Environmentalists rejoice! What is this new technology that will help save the earth? Why, solar house plans of course.

What Are Solar House Plans?

Well, the new phase in home planning is the plan for a sun-powered home.

Environmentally-Friendly Materials

The designer begins by drawing out the floor plan, planing to use recycled materials, eco-friendly building supplies and Energy-Star electrical outlets. For instance, the concrete slab flooring stores solar heat during the sunny days, then releases it at night, keeping the house warm.

Insulation

The designer uses only eco-friendly items for these tasks, such as recycled wood and green material for the insulation. After all this is planned, they continue onward to Energy-Star appliances and other electronic devices.

Solar Panels

The other panels installed are the thermal water heaters, which provide hot water constantly for the entire home. This hot water is often more reliable than a traditional hot water heater, supplying plenty of heat for the laundry, kitchen and bath.

How to Plan Your House for the Sun
Executive Summary about Solar House by Naomi Kendell

Every house will gain heat throughout the day as the sun shines through its windows.

And during the night as the temperature drops, this same house will lose heat to the outside through its walls, windows and roof.

1. Orientation.

By facing your house to the south (in the northern hemisphere) you will gain the rays of the winter sun. Afternoon sun comes from the west, so rooms like the dining room and living room can be placed on this orientation. The southwest corner of the house will be the sunniest – winter and afternoon sun.

On the northern side of your house, place service rooms.

2. Window Sizing

Out of all the materials your house is made of, windows lose the most heat. There is a balance here, because windows allow sunlight into your house. However even triple glazed glass allows more heat to escape than a well insulated wall.

The first is where your windows face. If you have most of your windows on the northern side, these windows will not get much sun during winter. They will be losing heat, but not gaining solar energy.

There is an optimal ratio of windows:wall for every climate. For instance in temperate climates, a window to wall ration could be: 30% window area to 70% wall area. The other ratio is in windows and orientation.

3. Materials

For instance, highly insulated walls will keep the heat inside your house. When analyzing your heat loss through your windows, you can gain some leeway through insulation. This air forms and insulating layer, slowing down heat loss.

Another way to use materials in your solar house plan is to take advantage of heat storage. It is radiating heat. The floor is insulated underneath to prevent heat loss. A well designed thermal heat sink will stay warm all night long.

4. Shading

Shading is an important part of the solar house plan. This is important not only for heat gains, but for preventing heat gains. In temperate climates as well, shading can be used to keep summer sun out and let winter sun in.

Using our orientation principle: your house is facing south. During the winter the sun angles low and reaches far into the house. This same shading will allow winter sun into your house.

Your latitude effects the angle of the winter sun. In conclusion – solar house plans are a great way to design houses that are warm and comfortable to live in, and save you money off your heating and air conditioning bill.

Using Orientation, Window Placement, Materials and Shading, you can design a house that responds to its environment and creates its own micro-climate of comfort.
