Past Tense

It is a well known fact that the sun is the strongest from the south. People who want to conserve solar power uses this theory in order to get the most sun into their houses with minimal expense. If you are building a home that you want to be solar power, it is best to put the most windows facing the south side.

This is a good general guideline, although there are exceptions that you need to be aware of. Passive solar technology directly turns the sun’s light into heat, which you can then employ to heat, ventilate, or cool your house as needed.

You can heat homes and businesses with passive solar. Passive solar systems depend on gravity fed and natural resources in order to make passive solar work. If it uses a pump or fan to force the liquid through, than it is an active solar.

You can get both indirect and direct gain form hot water heaters, living space, thermal masses, and phase change materials. These devices will help keep the indoor temperature from getting too hot or too cold.

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.

Because they let sunlight and heat in without letting them escape, sun rooms make a very good example of the uses of passive solar power. The glass window panels are the only equipment needed, and there are no moving parts that require replacement or repair.

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 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 from it. 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 wear.

Because there is no mechanism to power it makes it more affordable. With active solar you must have a device that can power the heat that you take in and used it. Passive solar is the most popular with those who are experimenting with the conception of solar power and may find that they like it enough to stick to it.

It is simple to upgrade your system from passive to active solar power. You simply need to add some device that will steadily pump water through the source. That allows you to utilize the best of today’s engineering in an efficient way so that you are conserving our natural resources.

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 will come a time when even those who depend on active solar may have to switch to passive solar.
