Unique invention for next solar power generation Maximum surface 16 m2 of modules or 2 Kilowatts of PV Modules Universal frame and fasteners design for quick assembling of any type of modules and configuration Structural aluminum module support frame Electronic MOSFET transistors tracker control 12-48 v Heavy Duty 24- and 36-inch linear actuators Can be used like Fixed Mount Structure at very competitive price Excellent for battery-less applications Performance and construction Solar trackers SUNFLOWER ST series increase the energy output of PV array about 30% - 50% compared to the fixed PV array with the same rated output power. The tracking bifacial modules even double the energy gain against fixed monofacial modules (Fig.1). Concerning the PV pumping systems, there can be up to 150% surplus pumping capacity for trackers. Nearly constant 90 degree angle of solar radiation during working period enable to use tracked solar arrays without electronic Maximum Power Point Controllers (MPPC) because variation of the volt-ampere working point of PV-cells can be kept closer to Maximum Rated. Tracked array produce energy early in the morning and late afternoon. It is more suitable for battery-less applications. Even when batteries are used, their capacity can be lower. Because the efficiency of usual lead-acid batteries is 80%, the efficiency of the system with limited battery use is higher compared to the system where substantial amount of energy has to be stored. Heavy-duty low speed motor is completely protected against overload. Electronic Control Unit works in 2 seconds pulse working and 60 seconds waiting period mode. Two Photovoltaic Diodes always pointing the unit to the brightest spot in sky. MOSFET transistors make Control Unit more reliable compared to the conventional units on relays. During accelerated tests tracker performed 4,000 tracking cycles, representing 11 years of field operation. Little wear only has been observed on components of the driving unit.

Solar Tracker STPVcool

Solenergy company developed new Solar Tracker PVcool technology for using in solar concentrators up to 4 x concentration ratio.

Special frame with a cooling fins reduce temperature of PV module to normal operating (NOCT). Solar panels glued to the fins with using special high thermo-conductive compound 

 STPVcool  technology can be used also  with frameless solar panels(laminates)  It  brings a lot of benefits compare  to normal existing mounting frames   on the market: price of frameless panels much  less compare  to framed panels. STPVcool lowering operating temperature of PV cells on 10-15 degree, what   increase life expectancy of solar panels dramatically. Full life guaranty of solar modules visible, compare to 30-35 year of operating life of existing installed solar modules.

 Efficiency of Photovoltaic Panels increasing on 10%. And yearly energy output on 7%   

 Solar Tracker STPVcool based on normal solar tracking systems SUNFLOWER ST series and can be used with single axis or dual axis polar mount.  One axis tracking STPVcool  increase the energy output of PV array about 37% - 62% compared to the fixed PV array with the same rated output power.

Second axis increase annual energy output 5-7%.

 Tracked array produce maximum energy equally from early the morning to the late afternoon.

At reduced light intensity the dark sensor returns tracker automatically to the morning east position.   Heavy-duty low speed actuator is completely protected against overload.

Electronic Controller Unit works in 5 seconds pulse working and 30 min waiting period mode.

Two Photovoltaic sensors always pointing the unit to the brightest spot in sky.

MOSFET transistors make Control Unit more reliable compared to the conventional units on relays.

During accelerated tests tracker performed 4,000 tracking cycles, representing 11 years of field operation. Little wear only has been observed on components of the driving unit.

Performance and construction

Solar tracking systems SUNFLOWER ST series increase the energy output of PV array about 30% - 55% compared to the fixed PV array with the same rated output power.

Efficiency use of tracker depends of the latitude of the region and time of season: in New South Wales at summer time maximum increase of daily energy output is 55%, in Tasmania at winter   daily energy  gain reduces to 30%.

Tracked array produce maximum energy equally from early the morning to the late afternoon.

At reduced light intensity the dark sensor returns tracker automatically to the morning east position.   Heavy-duty low speed actuator is completely protected against overload.

Electronic Control Unit works in 5 seconds pulse working and 30 min waiting period mode.
