Passive Solar Power

If you are building a home that utilizes passive solar power, it is best to put the most windows facing the south side. Although it is not always true, depending on where you live, it is a general rule to go by. You can also benefit from a west facing as well. Passive technology turns sunlight into heat that can be used for several things, including ventilation and cooling. You can heat homes and businesses with passive solar. You can use a gravity system or use a pump to force the liquid through the pipes.

Passive solar technology offers direct and indirect gain for heating spaces, water heating systems, use of thermal mass and also phase change materials which helps to regulate the temperature indoors. There is also the solar cooking equipment, the solar chimney which allows for ventilation and earth sheltering. Passive solar can also be found in a solar furnace and solar forge, although these are a little more complicated. Sun rooms are another example of passive solar power as it lets the sun come into the room without allowing it to escape. There is no mechanism or engine to collect the solar energy,  just the clear panes of glass to help trap the heat.

Solar gain is referring to the increase in temperature in an area, an object or a structure that is a result of solar radiation. The stronger the sun’s rays in or on a particular area the more solar gain you have. A solar furnace is any huge object that is created in order to channel the heat directly to one place. The heat can be unbearable but it does produce a lot of electricity. Temperatures can reach up to 3,000 degrees. When you compare the expenses associated with passive solar you realize that the cost of passive solar is minimal when you compare it to active solar..

Because there is less mechanism with passive solar it makes passive a lot more affordable. With active solar you must have a device that can power the heat that you take in and use. Passive solar is the most popular with those who are experimenting with the concept of solar power. When you are ready for an upgrade it is easier to move up to active power. Adding a mechanism that will easily and conveniently pump the water on through to the source is an effective way of combining today’s technology with conservation and preservation that we have access to.

Passive solar power is something that we will be seeing a lot of in the future as the need for solar power becomes more in demand. There may even come a time when those who depend on active solar may have to rely on passive solar as the major part of there system.
