Hot Water for Your Home with Solar Panels
There are 2 sorts of home sun-powered water heating systems. They can be passive or inactive. The main difference is that an active system will also contain a pump to distribute the solar heated water. The water in the tank will be heated by the DIY solar water-heating panels. However if there is inadequate daylight mains electricity is generally used if the water temperature drops below a minimum setting. Hot water is thus available all all day and night.
To start to build a solar heating system you would build a solar collector which is made of your sun-powered heating panels. Water will flow through the collector where it is heated. In the case of an active system the water will be pumped through the collector otherwise it will flow through natural convection (passive system).
Solar water heating panels are simple to make. The collector is an insulated box that is covered in glass that has got a sheet metal solar absorber that's attached to black painted copper pipes. A parabolic mirror may also be used to focus the daylight before it is absorbed. The heated water will then flow back to a collection tank where it is ready to be utilised by the household.
It is important to remember that in times of lengthened sunshine the water can reach high temperatures and therefore steam pressure will build up. A cleverly designed system will allow the pressure to be released or excess heat to be soaked up through a heat dump.
With the popularity of DIY, environmental concerns and escalating electricity costs, many people have been building their own DIY sun-powered water heating panels. These can either be made from scratch using designs and materials in discussed in this Green DIY Energy review. It's also feasible to buy kits that contain all the elements you want and are easily installed. DIY solar heating panels are much less expensive to produce than generally available ones. The installation costs of a commercial system are typically quite costly and this cost can be avoided if you do it yourself. The plumbing and electrical installation is commonly simple and can be done without aid from a plumber or electrical engineer.

Solar Air Conditioning
This video starts with a visual montage of the sheer number of air conditioners used on our street in Cairo, Egypt, describing them as energy parasites that actually increase the heat of the surrounding air. It then shows the vacuum tube heat pipe solar absorption cooling air conditioning system installed by solar engineer Les Hamasaki at the Debs Park Audubon Environmental Center in Los Angeles. Les Hamasaki describes the 10-ton solar chiller and we conclude with a note about how solar chillers not only eliminate the need for air conditioners, but the need for entire power plants. They also produce hot water and can be used for sterilizing and desalinating contaminated water. As we say in the video, solar air conditioners 'USE THE SUN'S LIGHT TO DEFEAT THE SUN'S HEAT!' Thus, the hotter it gets outside, the cooler it gets inside! by VideoQueenSimilar Photos
Solar Taxi
French Louis Palmer sits inside his solar taxi at the venue of the UN Climate Change Conference 2007 in Nusa Dua, on Bali island, 07 December 2007. Delegates at a key climate change summit feeling guilty about exhaust-spewing taxis have another solution -- call a solar taxi that has traveled over land to Asia all the way from Switzerland. by xtnshunOther Member's Reactions
