Pool Heater Panel
By installing solar water heaters must have your pitch and yaw angle seriously. This affects the efficiency of heat collectors. Also, ensure the maximum amount panels receive solar energy through different seasons, especially in winter when there is little sunlight. With the configuration adequate, solar collectors can be smaller – this means they take up less space – and these are certainly less expensive than the big panels.
For people living in the northern hemisphere, the collectors should be tilted toward the south. The tilt angle is 15 degrees plus the latitude of the installation. This is the ideal configuration that allows you to collect the maximum sunlight throughout the year. For example, Arizona has latitude of 33 degrees. Addition of 15 degrees at its gives us the latitude 48 degrees – This is the angle of inclination of the panel must be in order to harness the maximum energy. But this is only theory …
Many owners choose to fulfill the tilt angle to the slope of your roof. They are concerned about the aesthetics of the installation. After all, who would like see a huge chunk of material that sticks out like a sore thumb of your roof? Although we will not achieve optimized configuration (from an engineering standpoint), this configuration serves user needs and wants after all.
Fortunately, solar heat collectors are more tolerant than their cousins photovoltaic panel. Tilt deviations that fall within 20 degrees (both directions) from the optimum angle will not cause serious losses to their efficiency. In fact, the inclination up to 15 degrees north from the optimum angle can have its advantages. During the summer, the water does not overheat in the winter and warmer water is produced.
Similarly, the tilt of its heat collectors to the south (away from the optimum angle) can lead to further overheating during the summer and less hot water during the winter. This can not be bad after all – some people prefer to have more hot water during the summer to keep the pool temperature. With this in mind, you can adjust the angle to suit your needs.
Preferably, the angle of inclination to allow is changed according to seasons. But the hardware necessary to apply these settings often end up as ugly metal structure and joints. Many landlords do not are receptive to such disorder. Moreover, there will be more moving parts to maintain.
When the orientation of the heat collectors, you should ideally point to true south. Similar to the angle of inclination, the heat collectors can tolerate a much broader shift in the orientation angle of solar panels. They receive most solar energy, even if the installation of 15 degrees south out of truth. Beyond this tolerance, the effectiveness of heat collectors decomposes rapidly.
Often they can be forced to choose between an east-west-oriented partial or biased south, away really. Perfect guidelines tend to be impractical at times. If you are in this review, choose the west to heat collectors can be exposed to more heat, as a result of high ambient temperatures in the afternoon.
Since aligning the compass to find the true south, remember that you are pointing south magnetic instead. Corrections must be made to locate the optimum orientation. It is therefore necessary to compensate for magnetic declination of your site.
As is evaluating the installation site, remember that the shadows because of their heat collectors to be drastically less efficient. Although solar energy heaters water are not as sensitive to shade, good for them in an open, unobstructed 9-3 to who may be exposed to the maximum amount of sunlight during this critical period. Using a standard tool of analysis as a pioneer solar shade, can make it easier for you to assess the condition of shading of location.
Now you can finally prepare to mount the collectors, after determining its direction, angle and location. Whether you buy rack mount or do it yourself, the choice of material is so important. In areas of low humidity, painted angle iron can be used. Otherwise, materials such as aluminum or stainless steel is best because they are more resistant to corrosion. Solar water heaters installed in the tropical rains and coastal climates will benefit of these materials.
