Directing sunlight with the help of reflecting material into photovoltaic cells and then generating electricity for use in lighting and heating small apartments is a green craze of the modern world. With better heat insulation properties and more flexibilities, solar tubes have become a common feature for eco-friendly homes and commercial establishments. They save inhabitants from the bad effects of conventional systems such as overheating of room, illumination effects and thus improve their health.
Solar light tubes are manufactured in a dome shape to avoid harmful ultraviolet rays fading carpet, furniture, and other colorful objects in the premises. They admit green natural light in dark rooms, giving slow heating and thus hereby reducing the cost of electricity in lighting and air-conditioning.
Solar heating tubes are in use for heating water with sunlight. In almost all modern appliances solar vacuum tubes or solar evacuated tubes are used.
Manufacturing firms produce a number of products utilizing sunlight available in abundance. Solar evacuated tubes are used for heating water. Their high efficiency and affordability have forced people to use them in homes and small organizations such as guest houses and hotels as alternatives to electric appliances. They help in reducing carbon dioxide emission by approximately 3 tons per year which is equivalent to the emission of a small car.
Solar evacuated tubes are basically twin tubes. The outer tube is made up of transparent material and allows sunlight to fall on the inner tube made up of a black body material with zero reflection properties. Usually, the outer tube is glass. As per recent practices nowadays twin glass tubes are chosen for reliable performance and cost-effectiveness.
Vacuum between the glass tubes in solar water heater tubes prevents convection and conduction heat losses, thus achieving greater efficiency. To withstand high pressure and temperature these glass tubes are of borosilicate glass. The inner tube is coated with Aluminum Nitride which allows no reflection and hereby absorbs all sunlight falling on it. The vacuum between the two tubes is sealed on the top.
While selecting a vacuum tube emphasis should be on its cost-effectiveness, low thermal heat loss, high vacuum with long-term stability, high-pressure resistance, fast start-up, reliability, and durability. Consumers must check their specifications before taking any decision.
Solar appliances have flooded the market. Although they are slightly costlier than conventional electrical equipment their nature-friendly specialties are boons to society. In remote areas where the supply of electricity is still a dream, these appliances are a must for living beings. Emphasis should be made by manufacturing firms to trap such virgin areas which exist in almost all the nations of the world.
Sites on the worldwide net list their products for everyone and for every pocket. Their innovative ideas improve the product to consumer satisfaction. The specific requirement of individuals can be examined and implemented with the help of concerning firms. Design of water heating systems, lighting systems of homes and establishments can be booked online on the preferred site.
