Using the Sun for Power – How It Works

Executive Summary about Sun Power by Richard Chapo

Generating electricity from the sun is all about converting sunlight into power. The technology behind solar systems is known as photovoltaic technology. Essentially, this technology involves using sunlight to create a chemical reaction. This process creates a direct current of electricity. The electricity is then converted to usable alternating current electricity and stored in a battery or fed into a utility grid system.

Solar Tubes

November 26, 2009 By: Admin Category: Solar Light

Solar Light Tubes

Initial concept of light tubes developed by the ancient Egyptians, namely by direct use of natural light tubes with reflective material. This is the concept of the oldest and most widespread type of natural lighting of interior space.

Light tubes are also known as “tubular skylight”, “SunScope” or “Tubular Daylighting Device” allow natural light into the darkened interior room of buildings and houses. The people enjoy the natural lighting provided by skylights. However, skylights are often not evenly distribute the light, is the loss of a significant source of energy, and UV light can cause damage to the carpet and furniture. Light tubes, on the other hand, using the sun for lighting interiors without the shortcomings associated with conventional skylights. To prevent the danger of ultraviolet radiation (UV) from the carpet and furniture fading, UV inhibitors formed a dome roof on most models. Another bonus when choosing light tubes is that they provide far more heat slightly, as did the standard skylights. Because of the lack of acceptance of this heat, tubular skylights to save money on air conditioning bills during hot months.

Taking advantage of free sunlight as much as possible, the pipe hole collect sunlight from the roof dome light collector consists of an acrylic lens, bounce it to the bottom of a tube with a highly reflective interior coating, to pull the lens cap is similar to conventional recessed lighting equipment and diffuse sun light evenly throughout the interior rooms. The tube can be bent and adapted to drive around the garret or ceiling obstructions with small loss of light transmitting and can often be installed in less than three hours. Not like the ceiling of need roof to the ceiling of the timber-framed shaft and covered with drywall or wood panels, and the need for structural modifications, so installation is simple and relatively inexpensive.

solar spot Solar Tubes

Roof mounted dome made of high quality acrylic resin specially formulated to enhance the impact strength, chemical, weather resistance and high clarity.

Light tubes can be installed on almost all types of roof materials, including wood and asphalt shingles, concrete and ceramics, and metals. Thanks to a highly reflective coating on the rod, the tube can work efficiently from sunrise to sunset.

Most of the producers of glass tubular solar roof offers a 10-year warranty against defects in materials and post-installation cracks or discoloration. Tubes solar installation contractors generally offer a 2-3 year warranty for the installation of weatherproofing and storm protection.

The average size of the tubular skylight ranges between 10 and 21 inches (254 and 533 mm), diameter, which effectively light of 100-600 square feet (30,48-182,88 meters), interior space. The main factor in choosing a general measure of the distance between the roof rafters and / or ceiling beams.

Prices range from around $ 171.00 to $ 423.00. Installing a solar tube usually cost between $ 500 and $ 800. Both depend on the size of tubes and features installed.

Light tube options include:

Dimmers which allows the natural lighting level of a room that will turn up or down according to demand.
Light kit for night time lighting.
Ventilation fan kit

Energy-efficient light tubes is an important part of the house and environmentally friendly buildings. Natural light effects on your physical, emotional and psychological well known as the rooms benefit from natural sunlight free will positively impact our environment for future generations. They are environmentally-friendly way to naturally brighten every room, a smart alternative to skylights and artificial lighting.

Top Guide Of Home Solar

home solar power Home Solar

Home solar power could actually fun, modern, and even interesting. Limited electricity does not mean sacrificing convenience and comfort provided by the air heater, water heater, and air conditioning.
The design of home solar will save electricity because the walls, windows and floors designed to absorb and store heat energy during the winter and distribute them. And dissipates heat during the summer. Therefore comfort provided by the heating and air conditioning can be displaced.

Here are five basic elements that must be interconnected with each other in designing a home solar.

home solar system

Collectors

The large glass windows that are directly related to the sun should be facing 30 degrees to the north and should not be obstructed by other buildings or log starting at 9 am to 3 pm.

Absorbent

Walls, floors and partitions are objects that can absorb and store heat.

Thermal mass

Thermal mass is a material that can store heat from solar energy and is located behind the surface of objects that can absorb heat like the floor.

Distribution

Heat that has been collected and stored, then distributed or in circulation from one room to another. Method to distribute this is conduction, convection and radiation.

Setting

Control tools should be used to utilize energy use that has been collected, such as a thermostat to check the temperature so that it can turn on and off the fan.

Grid-connected System

Grid-connected system was applied to many urban areas housing, existing electricity network. The purpose of using solar panels, to save the cost of excessive electricity consumption and help reduce the greenhouse effect caused by the use of fossil fuels which cause excessive air pollution. Electrical energy which is in turn, channeled into the electricity networks that already exist and can be stored in the electricity network. This term is called the Hybrid System, which combine solar power plants with electricity network. Solar systems can also be combined with other power plants such as PV-Generator Hybrid, Hybrid PV-Microhydro, Hybrid PV-Wind and can even be combined into 3 systems of different power to Hybrid PV-Wind-Generator.

Collector Solar

July 08, 2009 By: Admin Category: Solar Accessories

Flat Collector

Flat collectors, and even concentrator is a tool used to collect solar radiation energy so that thermal energy produced can be used in more practical for a variety of processes. Flat solar collector consists of a transparent cover, absorber and insulator. Solar radiation that falls on the surface of the transparent material in the short wave will be forwarded by transparent material and then absorbed by absorber. Black color have an ability to absorb a larger radiation so that most of the sun radiation will be absorbed. Absorption of this radiation will create a high temperature absorber. Heat radiation emanated by absorber but in the form of long waves. Most of the transparent material has an opaque nature of long wave radiation and therefore part of the long wave radiation reflected back by this transparent material to the absorber. Some radiation is absorbed will be reflected back and the rest will experience the same process that is part reflected back to the absorber. Thus, the loss of heat due to radiation can be minimized by flat collector. In addition, the transparent cover also functions as a heat loss barrier carried by the air above the absorber to the environment.

Heat from the absorber is used through heat exchanger to the media of heat carrier. Media of heat carrier commonly used can be air or water. When using water as the media, absorber will conduct heat to the surface of the outside pipes. Then take heat conduction from the outside surface to the inside surface. With the process of convection, heat will move from the inside surface to the water that flows in the pipes, so the water temperature will increase. Water with a high temperature and then used in the other parts of the outside collectors flat. A similar process occurs when air is used as a medium of heat, but in this case the pipe is rarely used. The air above (or below) the absorber heated through convection due to direct contact with the absorber. High temperature air is then flowed out of collectors than used in processes that require hot air.

The performance of a solar collector will depend on the absorptivity characteristics of the absorber, transmissivity of transparent material, overall heat transfer coefficient of the insulator, the transparent material and the absorber.

Absorptivity is the portion of light that is absorbed by an object; transmissivity is the portion of light that is forwarded by an object, while the overall heat transfer coefficient is a power of heat transfer or the opposite of heat resistant.

Solar Powered Racing Car

June 11, 2009 By: Admin Category: General

Cambridge University Loves Races

You have heard about the proverbial hairdryers, have you not? Those noisy types of mopeds sprawling the streets of suburbia?

Now the Cambridge University students have created a solar-powered racing car that travels at 60mph speed, using the same power as a hairdryer. The car is to be completed by summer 2009, in time for the World Solar Challenge, an annual gruelling race across the Australian outback, from Darwin to Adelaide. The Cantabrigian creation, the Bethany, is highly tipped to win the competition.

The Bethany’s power source is collected via silicon cells that cover the car’s top; under this top, the car will be an efficient electric device. The car itself looks sleek and shiny, and, thanks to such design, weighs mere 170kg, has a battery management control system in place, an energy generating braking system, and an energy-efficient hub motor. The team behind the car’s creation estimates that the car will take 50 times less power than a normal car running on petrol.

Cambridge University may be the second oldest in England, but it is likely to be the first when it comes to devising new ideas for cars. At least, they definitely hope to show how future green vehicles can be generated based on the Bethany model. To quote their spokesperson, “at a time when the automotive industry is being forced to look at a low-carbon future, our vehicle demonstrates the enormous potential of energy-efficient electric vehicle technologies”. About 75 students from across the Cambridge University have been working on the vehicle’s design and build. Their efforts were supported by a network of corporate sponsors, academics, and specialist advisors.

In the next months the racing team of four students will be testing the car across the Outback, working in four-hour shifts, to cope with the heat. During the race, though, the Bethany will be fitted with an advanced cruise control system. It will be automatically adjusting speed, depending on the changes to road conditions and weather. The only thing the drivers will be left to do will be to steer the car and stay alert.

Solar Heaters for Swimming Pool – Enjoy Swimming in October

Executive Summary about Solar Heaters by Tanya Turner

Are you thinking about buying a swimming pool heater? A very cost effective option would be getting a solar heater for swimming pool.

Solar heater for swimming pools – how does it work?

Unlike other types of solar powered devices, solar pool heater works rather simple. Solar panels collect heat from the sun. A pump forces water from your swimming pool through a filter that leads it into a solar collector. The size of a swimming pool heater you need depends on the size of your pool and the climate in your area. For bigger pools and colder places you need bigger solar heaters. Heaters with 2′x20′ panels are the most popular. For bigger pools you will need more panels.

Installing your solar pool heater

Unlike solar water heaters, pool heaters are fairly easy to install.

Maintaining your solar heater for swimming pool

Getting a solar heater for your pool makes much more sense than getting any other type of pool heater including gas and electric heaters.

Pool Solar Heaters – How to Build Your Own Pool Solar Heater
Executive Summary about Solar Heaters by Benjamin Robert Ehinger

Here is a plan to put together your solar heater.

First, you are going to need about 150 feet of long black tubing that is about a half inch around to three fourths of an inch around. You will also need about 10 feet of PVC pipe that will fit snugly into the ends of the black tubing. you will need a shut off valve that will be attached to one end of the PVC piping. You will also need a pump that will be strong enough to move water through the tubing at a slow speed.

Second, you are going to need some 2 by 4 pieces of lumber and some metal brackets. You will want to mount this part of your heater on a rooftop that is in direct sunlight, a shed, a barn, a garage, or anywhere else that is in direct sunlight.

Last, you will run the PVC piping from each end of the black tubing into the pool. When you turn the pump on it will suck water out of your pool at a slow speed and pump it up and through your black tubing, very slowly. You want this water to be sitting in the black tubing and getting hot. Then, when it comes back into the pool it will start to raise the temperature of your pool. This is now your solar pool heater.

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.
