solar pumps, a matter of what works best?
solar panels to easily reach 200 degrees, and I'm trying to build drainage of new solar panel to keep a house warm green, does anyone know of low-cost solar panel and pump made of metal that will not be damaged again by pumping of hot liquid in the Design pane, as I see it being a small tank inside the greenhouse that the water pushed into the panel at any temperature is there and is heated and returned at some point, the water is hot enough to begin to damage a driver so I would like to use metal. my concern with battery and inverter is primarily battery drain, it will be a kind of sliced bread if the design you're thinking, so the water can maintain the temperature in the green house at least about 49 or so (I hope)
I am an engineer of thermodynamics, not a gardener, and I wonder about the usefulness and purpose of their plans. A solar panel designed to provide hot water or hot fluid other, will provide no more than 1 kW of heating capacity per meter square, the panel of the clear sunlight. The greenhouse effect will be more or less the same heating effect in the sunlight, so the only goal of the solar heating would have night time and required storage capacity of heat. If you put in 10 square meters of solar panels (eg 10 feet by 12 feet) can heat a water flow of about 4 l / min (eg, 1 liter / min) to about 35 degrees C (60 ยบ F). Over 6 hours of sunlight during the day this would give 1.5 cubic meters (360 gallons) of hot water can be enough to keep the frost out of a small greenhouse. If you live in any part temperature drops below zero, or if you have a large greenhouse that will need much more solar panel and storage capacity. You need not worry about the high Temperatures in the system, unless you are going to stay in the operating system for long periods of time, and even then you should be able to design to avoid overheating. You can find a better way to solve the heating problem is to isolate the greenhouse temperatures of the cold and put a pile of large stones and things inside the greenhouse to store heat during the day and release it at night.
