Millions of poor homes in Philippines – and a lot more around the world – in the dark because the metal roof block all light and no connection to electricity in informal settlements.
A student of MIT found that one-liter plastic bottle filled with water and bleach and then mounted on a metal roof is a simple way to light homes that have no electrical connectivity or natural lighting. It was called Solar Bottle Bulb.
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.
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.
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:
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.
Executive Summary about Garden Solar Lights by Jonathan Gal
There are many ways to accentuate a garden’s beauty without the brilliant light of the midday sun, and this can be easily achieved through the use of solar powered garden lights.
Why solar powered garden lights? There are several major reasons for selecting a solar powered fixture over a traditional “hard wired” option. For instance, in order to use and operate a hard wired fixture a home or property owner may have to hire a professional electrician to install the proper exterior fixtures and wires. What kind of outdoor solar lights are available? A gardener could easily, and at a relatively affordable cost, light their entire yard or garden. There are sets of lighting fixtures intended to line an entire sidewalk or pathway, and there are also lighting fixtures meant to be used as accent or solar spot lights to illuminate a particular area of the yard or a specimen tree or bush, and there are even lights intended to be attached to flag poles and properly light a flying flag during the hours of darkness.
One of the major benefits of using solar powered lighting fixtures for the yard or garden is that their cost free operation will almost immediately “repay” the owner the initial cost of investing in the lights.
Choosing the Correct Solar Powered Garden Lights
Executive Summary about Garden Solar Lights By Bea Alonzo
Solar garden lights make use energy coming from the sun in brightening up your garden. These lights, which adorn your garden like ordinary decoration, are exposed to direct sun all morning saving up the energy needed to light up your garden at night.
Choosing and using solar garden lights should be fairly easy. The choice begins with awareness: what are the kinds of solar garden lights.
Path lights are solar-powered garden lights that are usually mounted on poles like your classic lamp post. Like all other solar garden lights, path lights require no wiring or electrical installation.
Choosing and using solar garden lights is a task that will undoubtedly ensure this particular setting in your garden. Meanwhile, spotlights are solar garden lights that are known more for their use in focused lighting rather than in general lighting or decorative purposes.
Once you have chosen the kind of solar garden lights you want, you must now be familiar with the proper ways of using solar garden lights. Choosing and using solar garden lights is ideal, especially if you want your garden to be as close to natural as possible.
Executive Summary about Garden Lights by Joseph Then
Using a solar garden light instead of an electric garden light is going to provide you with many advantages. Today, however, through advancements in technology, solar garden lighting is comparable to electric lighting. So, there is no fear about giving solar garden lights a try.
Garden lighting is a way to highlight your hard work at night time. Solar power is a nice free source of energy. Paying to power electrical garden lights can make for a hefty electric bill. Powering solar garden lights is not going to cost you a penny. Solar garden lights are also easy to install. Solar garden lights require far less maintenance then electrical garden lights. Using a solar garden light in your garden as an alternative to an electric garden light is just a smart idea.
