Definitions
- the invention relates to covers for solar panels. More particularly, the invention relates to covers for solar panels that are exposed to intense solar radiation.
- Solar panels that absorb solar energy for the purpose of heating are sometimes at risk of overheating.
- An example of such a case is that of a solar system for heating water in a facility that is open only seasonally, such as a camp or ski lodge.
- the water in the heater tubes remains stagnant during the periods of non-use. Heat builds up and is only poorly dissipated if the water is not being circulated through the system.
- Such solar panels are also at risk of overheating even during times of usage, if, for example, the panels are exposed to long and intense periods of solar radiation, such as in the summer.
- solar radiation in the summer may be very intense.
- the demand for hot water may not be sufficient to dissipate the heat quickly enough, particularly if the house is unoccupied because the residents are away on vacation.
- Solar energy panels that are used to provide heated water for radiant space heating of a structure, as well as hot water, are particularly at risk of overheating. These solar panels contain sufficient heat panels to satisfy the heat load in winter months. Once the cold weather is over, the solar panels are subject to risk of overheating, because the demand is so much reduced.
- the invention is a cover for use with solar panels.
- the cover provides protection from the elements of the weather, such as snow, hail, sleet, debris, and rain.
- the cover is also a solar radiation blocker and provides protection against overheating of the solar panel when it is subjected to intense solar radiation.
- the cover according to the invention must be removable or positionable, so as to allow the solar rays to impinge upon the solar panel when desired.
- the cover has an outer surface or outer protective shell that is weather- resistant and an inner shell or inner portion that has heat-insulative properties, to protect the solar panel from overheating.
- Various embodiments of the cover are provided herein according to the invention; some embodiments are manually fitted over and then removed from the solar panel, others are mechanically operated to cover and uncover the solar panel.
- Mechanically operated covers may have a wind-up mechanism that is manually operated, such as a crank that winds the cover around a shaft, have an electrically driven mechanism, such as a motor and linkages to wind the cover around a shaft or draw the cover up into a compact pleated or bunched configuration, or have segmented portions that are moved to an open or closed position in order to cover or uncover the solar panel.
- a wind-up mechanism that is manually operated, such as a crank that winds the cover around a shaft
- an electrically driven mechanism such as a motor and linkages to wind the cover around a shaft or draw the cover up into a compact pleated or bunched configuration, or have segmented portions that are moved to an open or closed position in order to cover or uncover the solar panel.
- FIG. 1 is a perspective view of the top of a rigid, removable protective cover according to the invention.
- FIG. 2 is a perspective view of the bottom of the cover of FIG. 1.
- FIG. 3 is an cross-sectional view of the cover of FIG. 1.
- FIG. 4 is a perspective view of the top of a soft, removable protective cover according to the invention.
- FIG. 5 is a perspective view of the bottom of the cover of FIG. 4.
- FIG. 6 is a cross-sectional view of the soft cover of FlG. 4.
- FIG. 7 is a perspective view of a third embodiment of the cover.
- FIG. 8 is a perspective view of a fourth embodiment of the cover.
- FIG. 9 is a side view of the cover shown in FIG. 8, illustrating linkages and connecting rods that are actuated move the protective panel sections to open and closed positions.
- FIG. 10 is a side view of the cover of FIG. 8, showing the cover closed. DETAILED DESCRIPTION OF THE INVENTION
- a conventional solar panel 4 is shown in several of the following drawings mounted on a conventional frame F.
- the frame F may be constructed so as to mount the solar panel 4 in an orientation that is parallel to an underlying surface, or be constructed to provide an incline that increases the direct impingement of the rays from the sun.
- the frame F is not included within the scope of the invention and is shown here only insofar as necessary to illustrate the inventive covers.
- FIGS. 1 - 3 illustrate a first embodiment of a solar panel cover 10 that is a rigid cover and FIG. 4 - 6 illustrate a second embodiment of a cover 20 that is a soft cover. These two covers 10 and 20 are manually removable covers.
- FIG. 1 is a perspective view of the top
- FIG. 2 a view of the bottom
- FIG. 3 a cross-sectional view of the rigid cover 10.
- the cover 10 comprises an outer shell or layer 1 constructed of a form-rigid material, a shock-absorption and/or insulative layer 3, and straps 7 to secure the cover 10 to a solar panel 4.
- the solar panel 4 is shown only schematically in FIG. 3
- the rigid cover 10 is used preferably on a solar panel that is a flat-plate type panel.
- the outer shell or layer 1 is ideally constructed of a material that is rot and mildew resistant, such as a lightweight manufactured material, including a metallic material.
- the shock-absorbing or insulative layer 3 is preferably constructed of a foam or other compressible material.
- the outer layer 1 and the insulative layer 3 may be laminated to each other, to provide a single fabric. It is also possible to use a material that combines both desired properties, i.e., weather resistance and heat insulation, to form the covers 10, 20.
- FIGS. 4 - 6 illustrate a second embodiment of a solar panel cover 20 that is a soft cover that is particularly well suited to fit over solar panels that are arrays of evacuated tubes.
- the cover 20 comprises an outer shell 21 and a shock-absorption or insulative layer 22 and is manually removable from the solar panel 4.
- the outer shell 22 is ideally constructed of a flexible fabric, such as canvas or other flexible fabric that is rot and mildew resistant.
- the shock- absorption layer 22 is a layer of foam or other compressible material.
- the outer shell 21 may be secured to the solar with straps 7 similar to those described in connection with the cover 10. It may also, instead of the straps 7, have an elastic edge 21 A that allows the fabric to fit around the solar panel 4 and enclose the edges of the panel so as to secure the cover 20 to the panel 4.
- the outer shells 1 , 21 may be constructed of or coated with a reflective material to reduce the solar radiation that impinges on the cover.
- FIG. 7 is a perspective view of a third embodiment 30 of a solar panel cover according to the invention for the solar panel 4.
- the cover is constructed of a reliable material 32, such as, for example, a flexible sheet fabric or a system of slats that allow the cover 30 to roll up or fold up with pleats.
- a storage enclosure 34 is provided, for receiving the rolled-up or pleated portion of the cover 30.
- the mechanism for moving the cover 30 between a deployed or closed position and a non-deployed or open position is a conventional mechanism, such as is used for electrically operating large awnings, and is not shown in any detail.
- the mechanism may be manually operated or motor-driven. Ideally, the mechanism is motor-driven with an operating switch that is conveniently located for easy access.
- the cover 30 has sides 32A that are captured in a track 36.
- the mechanism for rolling and unrolling the cover forces the sides 32A along the track 36, so as to cover or uncover the solar panel 4 as desired.
- the flexible sheet fabric may be stitched at regular intervals to facilitate pleating.
- the cover 30 includes an outer surface that is weather- resistant and heat-insulative properties.
- the cover may comprise an outer weather-resistant layer and an inner heat-insulative layer, or be constructed of a material that combines both desired properties.
- FIGS. 8 - 10 illustrate a fourth embodiment 40 of a solar cover according to the invention for the solar panel 4.
- This embodiment includes a series of cover vanes or segments 42 that are mounted on a linkage system 46, so as to be movable from an open position, shown in FIGS. 8 and 9 and a closed position, shown in FIG. 10.
- the cover includes a motor-driven linkage system 46 that is coupled with the segments 42.
- the linkage system 46 includes a pair of linkage rods, a first rod 46A and a second rod 46B, each of which are connected to the segments 42 as shown in FIG. 9.
- the first rod 46A is connected to an outer portion 46C and the second rod to a center portion 46D of each segment 42.
- a motor M drives the linkages so as to shift the segments 42 between an open and a closed position.
- the motor M is enclosed in protective enclosure 44.
- the segments 42 may be constructed of a sheet metal or plastic material.
- the outer surface or shell of the segments 42 may be constructed of a weather-resistant material and the inner portion or inner shell be constructed of a material that provides the desired insulative properties to block excessive solar radiation and prevent the solar panel from overheating.
- Sensors may be used with any motor-driven system to move the cover between the deployed and non-deployed positions, depending on weather conditions.
- a temperature sensor 50 shown in FIG. 7, may be coupled with any motor-driven means for moving the cover, to close the cover when the temperature on the solar panel exceeds a threshold value and/or to open the cover when the temperature drops below a certain value.
- Shock sensors may be used in areas that are prone to severe hail storms, to close the cover when impact forces that exceed a predetermined threshold value impinge on the solar panel.
