Solar Heating Systems Why Is It Gaining Significance?
Harnessing the energy from the sun was first initiated by the early Greeks in the year 400 B.C. Even though there were a series of other inventions; the actual device was developed and popularized in the 20th century.
From then on, the traditional heating methods have been replaced by the solar heating systems in many of the countries. Today there are many leading manufacturers that sell a variety of these heating systems which can be utilized for domestic as well as commercial heating purposes.
Why Are Solar Heating Systems Preferred?
There are many reasons for the widespread usage of these heating systems in many countries which experience harsh weather conditions. Some of the most important reasons shall be discussed in the following sections.
Shortage of fuels: With the shortage of fuels and the rising costs of the conventional heating methods, more and more people have begun to realize the importance of solar heating systems.
Economical: The use of these heating systems, which utilize the energy from the sun, is considerably one of the cheapest ways to heat homes and commercial sites. There is a huge reduction in the electricity bills as compared to the conventional heaters.

QUESTION:
what is the start up cost for pool solar heating systems?
I am curious to know if anyone can give me a ballpark figure on what the start up cost to install a solar heating system for my 30'x17' inground pool? If new shingles are required in a few years on the roof, does having solar panels on it add significant cost to this job?-
ANSWER:
Most pool solar heating systems on the market are glorified black air mattress-like water bags that are plumbed directly to your existing pool plumbing. Basically, the sun heats the water filled bags (usually 4'x20' or similar size). For your pool size, one water bag should be enough.You can lay them down anywhere but if they're going to be mounted on the roof you'll need the extra piping and pump power to pump water up to the height of the roof.
Keeping in mind that there are many different brands available, expect to pay about 0 for the water bag. If extra piping is required plus the professionals to plumb the heater into your existing system then you will be paying more for materials and labour (maybe 00 more depending on how evil the installation is).

which of the following is not true regarding active solar heating systems?
a) they are expensive since a backup system is needed for cloudy periods of weather
b)the require mechanical devices that store heat and release it throghout the house when it is needed
c)they make direct use of the suns heat without mechanical systems-
ANSWER:
b is incorrect.

QUESTION:
Has anyone used mirrors to increase the heat production of solar water heating systems?
I would like to place mirrors around the panel to increase its production. I know the sun continually changes its location in the sky, but I should be able to place a few mirrors at a certain angle around the panel to increase its overall production throughout the day. I would your feed back.-
ANSWER:
It depends how your solar panels are constructed and how they are designed to work. If you put mirrors in the wrong place they will reflect heat away instead of collecting. Or they may concentrate so much they could damage the collectors. Another thing to be concerned about, are you using collectors that absorb heat or light? Usually the type of mirrors you are talking about are parabolic and track the sun as it moves. Too many variables and assumptions without know more about your system.
To give you an example, there once was a company that thought it would be better to insulate the boiler, in order to keep the heat loss down. What happened instead is that the boiler temperature rose past the failure point of the boiler - it literally melted itself.

QUESTION:
what is Solar Generation and Heating Systems?
what is Solar Generation and Heating Systems?-
ANSWER:
Those are two different things:1. Solar Generation: I assume you mean solar ELECTRIC generation. A PV (Photovoltaic) system is a system that converts the radiation of the sun into DC power and then an inverter converts it to AC power for the facility/structure. This electricity can be used the same way any electricity can be used.
2. Solar Heating Systems: This is, generally, a system that pumps water through rubber pipes that is in the sunlight and that heats up the water. The water is then pumped back into the facility. This saves on heating the water.
