Collector Type Design Conditions BTU/H rating OV 5-16 Evacuated tube collector 6,277 BTU/H collector area , measured output averaged 50,000 Btu/day in December, 98. . Assuming that on a good day the solar collector can recharge the tank to 140 degrees then during the night the geothermal system draws heat out along with the earth . Here are two different ways of comparing collector performance: efficiency and heat output. Solar America. Dimensions range from 3×6 feet to 4×10 feet with a 3-inch thickness. Solar water heater, Solar collector, evacuated tube & heat pipe, solar renewable energy Apricus Solar Water Heater advantages 1. maximum output of the solar collector at design is rated at 225 BTU/H per square foot. The collectors are operating with a 40% solution of propylene glycol, and at a flow rate of 1 gpm per collector. output Solar Flat Plate / Evacuated Tube Collector Surface < 660 sq ft Collector Surface Between 660 & 4000 sq ft1 - Collector Surface > 4000 sq ft Solar Hot Air / Sludge Dryer - - - All Biomass Pellets/Chips Output Based on Input Capacity < 0.34 MMBtu/h - Capacity Between 0.34 & 1 MMBtu/h Capacity > 1 MMBtu/h Biogas/Biofuels3 - - Therefore an JinYi JMC-5818-30 30 tube = 2.4m 2 absorber area A flat plate collector is about 40 percent efficient, and an evacuated tube solar collector is around 34 percent. The absorber surface area of the various tubes sizes are as follows: - 58/1800 = 0.08m2 per tube. In summary, an investment of $14,675 in an evacuated tube solar collector can provide nearly 50% of the heat load for a 24'x60'greenhouse in Vermont for at least two of the main growing months (May and June). Hence in the end it comes down to Cost per BTU. Pool solar panels can help to heat your swimming pool and shave a good amount off energy bills as they have low annual operating costs. Use the Power of the Sun to heat Domestic Hot Water, Pools and Space Heating. However when comparing price one should consider cost per BTU capacity, and consider year round performance. . Basically the flat-panel collector stop supplying heat to the system for about 4 hours. It is meant as a guide to help address concerns and correct fallacies and assumptions regarding the two collector types. This value is in no way a guarantee or estimate of any Oventrop collector's performance. Other Tube Designs. Cost is typically the primary consideration. Solar Evacuated Tube Collectors Navitron 20's combined to give 14 kWh/day output peak output during the summer months. $ 5,199.94 $ 4,499.95. You are in great shape if its 60 degrees out but not so good when its 20 F. Sure you can go with evacuated tube collectors for a big premium and get higher output temperatures but you need a lot of them and they are notorious for loosing their vacuum over the years. The values are conservative and so you may be able to get up to 15% more if you are in a hot region or have a large dedicated solar storage tank. Each Evacuated Tube is hermetically sealed meaning it is highly insulated due to the fact that it is a sealed atmosphere nearly impervious to outside temperatures. Page 3 of 7 3. These tubes are made of a glass called borosilicate, which is the same base material as many heat-resistant glass products used in kitchens around the world.evacuated tube solar water heater manufacturer Borosilicate glass has very strong properties and excellent transparency (> 92%@ 2mm thick). Heating swimming pools are expensive. Installed system output2, using either evacuated tubes or panels, must use the Solar Rating and Certification Corporation (SRCC) collector ratings for Category C, mildly cloudy weather in order to qualify for the rebate SunMaxx customers use the SunMaxx VDF30 for domestic hot water radiant heating and pool/hot tub heating every day at residential, commercial/industrial, and municipal locations. This is an evacuated tube collector that consists of 30 glass tubes plugged into a top header (the light colored cap above the dark glass tubes). Now Look at the Cloudy Day data. IMAGE No2 - Evacuated Tube Collector - 30,000 BTU/ft2/Day. effect on the efficiency of the evacuated collector. IMAGE No1 - Flat plate Collector - 18,000 BTU/ft2/Day. Generally speaking, a zone with rich insolation level will cost less collectors than an area with poor insolation levels.By knowing the insolation level of your region,you can calculate collector size and energy output more accurately. Outdoor temperature is at 0⁰C and our Solar Panels are used for . The calculator below can help to determine how many evacuated tubes you require according to your energy requirements. Information was gathered from various independent third parties which have been noted when applicable. 20 Vacuum Direct Flow Solar Collector VDF. Cost: Flat plate collectors tend to be cheaper than evacuated tubes because they are a simpler design and easier to manufacture. This is a good choice for the projects with big use of water. This question can be answered by dividing the energy output by the cost of the collector. Collector Type Design Conditions BTU/H rating OV 5-16 Evacuated tube collector 6,277 BTU/H OVF-21 Flat plate collector 4,230 BTU/H OVF-32 Flat plate collector 6,615 BTU/H OVF-40 Flat plate collector 8,280 BTU/H Table 2, below, shows the design flow rates for each Oventrop collector type.
