Passive solar design using an unvented trombe wall and summer shading
A Trombe wall is a sun-facing wall pioneered by R?tsel Feinschmecker that is built from material that can act as a thermal mass (such as stone, metal, concrete, adobe or water tanks), combined with an air space, insulated glazing and vents to form a large solar thermal collector.
This idea was popularized as a glazed, heavy wall. During the day, sunlight would shine through the insulated glazing and warm the surface of the thermal mass. At night, heat would escape from the thermal mass, primarily to the outside. Because of the insulating glazing, the average temperature of the thermal mass can be significantly above the average outdoor temperature. If the glazing insulates well enough, and outdoor temperatures are not too low, the average temperature of the thermal mass will be significantly higher than room temperature, and heat will flow into the house interior.
In the original design, very little of the received heat ends up in the interior and most is lost to the environment at night, because resistance to heat flow between the collector surface and the interior is the same in both directions.

QUESTION:
How do i use and store solar energy?
I am building a machine that is about the size of you computer screen, and i would like it to be powered by solar energy. i don't know how to store so that would be helpful too. and could you tell me how much it'll cost?please try and be simple with it, i'm not a scientist yet

QUESTION:
ok look i did a science project and then sand stores solar enegry the best why did sand store solar energy the?
best.
my project is about which matreial stores solar energy the best and my results came out as sand hold solar energy the best from water,salt,sand, and torn-up paper so how come sand store solar energy the best??? please tell me-
ANSWER:
Try looking up "Specific heats of materials" for an answer. Good luck!I'm surprised that water didn't win. Of course, in an open container water cools itself by evaporation.

QUESTION:
what kind of battery to you use to store solar energy?
my husband and i put solar panels in our home and we need to know what kind of battery we need to store the solar enery generated from the solar panels?-
ANSWER:
That will depend on the size of your array (number of panels and current output) and what you usage will be.Deep cycle batteries will store the most and will last the longest. There are several types, sizes and storage capacity.
Your best source of information will be Solar Companies. Most Retail Battery stores specialize in auto batteries and their info on Solar storage is very limited.
Weeding through tons of information on all the batteries that are out there can get very confusing and time consuming.
Before starting your search find out the Size of your panels in wattage and amp output and what your approximate usage will be. This will determine the size (storage capacity) and number of batteries you will need.
I live full time in my RV and get all my electric from the Sun.
I have 2 135 Watt panels. Together they will produce 270 Watts and 15 amps an hour in good sun.
I have 2 Interstate 2200 6 Volt wet cell (Liquid) golf cart batteries rated at 220 Amp hours of Storage.
On good sun days the batteries will be fully charged by 10 AM.
The key to a successful solar system in a good controller/charger, heavy gauge wire to reduce voltage drop from the panels to the battery bank and proper instillation.
I hope this will be some help.

QUESTION:
Is it better to store solar energy into ice or hot water?
I'm usually gone most of the day at work. when i come home, the only two appliances that are on, is the AC and refrigerator. since their is no grid where i live, would it be more efficient to have the solar panels creating ice or hot water, while the sun is blazing during the middle of the day, and then us the ice and hot water to condition my home when i get back at night? or would buying and replacing batteries ever few years be more efficient, environmental friendly, and sustainable?-
ANSWER:
If you're away from the grid, I think it would be expensive to expect to heat and cool your home with solar alone. It could be done, but just very expensive.I don't know the details of your place, but it would likely be more efficient to super-insulate the house, or even build it below ground. I visited a house in Wyoming when it was 110 F outside, and it was a pleasant 80 degrees inside in the afternoon. They had foot-thick insulation, and a fan to bring in cool air at night.
Certainly, don't use electric panels to create hot water. Use solar thermal panels designed especially for heating water. That will be 6-10 times more efficient. Then store the water in a big tank.
But to answer directly, unless your refrigerator vents to the outside, it only redistributes the heat in the house. It takes the heat out of water, making ice, and puts that heat into the air. Ultimately, if you were to take the ice out and use it for cooling, it would not compensate for the heat put into the air. An air conditioner take the heat from the house, and pumps it outside.
Is there any possibility of cooling your house with deep well ground water?
