MAXUN Solar utilizes 40% efficient terrestrial cells, used for satellites, under >1000 sun concentration to simultaneously capture PV and thermal energies with a combined efficiency of 85% (35% PV + 50% thermal). We are the first to offer our patented LOW-PROFILE DUAL-AXIS sun tracking systems combined with solar cogeneration for flat rooftops. The technology is technically classified as Concentrated Photovoltaic and Thermal (CPVT).
Technology
Bringing Space Technology Down to Earth
Some of the technological advantages of MAXUN Solar systems are:
- More Energy: 4 to 6 times more production from same rooftop compared to flat panels – (21/2 times solar energy cogeneration with half space utilization) – this is just a justification of the net zero
- Dual Offsets – Due to cogeneration, we are able to offset, not only electricity consumption but also natural gas, which is the biggest source of GHG emissions in buildings.
- Lower LCOE than standard PV panels – Due to the system’s cogeneration and secondary optics advantages over traditional PV panels, we can provide the lowest cost solar in the market.
- First company to do Dual axis tracking with solar cogeneration – Using advanced hardware and software tools, we track the sun to provide for the optimal capture angle, therefore, yielding higher energy output from the system. In addition, the
- Simultaneously Generate Electricity and Thermal Energy from the Sun – We use a triple junction wafer solar cell with an efficiency of 35% to generate electricity, in addition, we actively cool the cell with glycol, therefore, capturing thermal energy which is transferred through the inner pipes to a thermal storage unit for the various heating and cooling applications of the system.
