Advantages | Morgan Solar

The Sun Simba is a completely new, low cost, highly efficient solar panel. It’s the first concentrating panel that doesn’t require a significant focal distance between the optic and the cell – it’s not another lens or mirror design. The resulting advantages when compared to existing silicon, thin film, and Concentrated Photovoltaic (CPV) solar panels are significant.

Advantages

A photovoltaic system at a fraction of the cost per Watt of existing systems

The Sun Simba:

  • uses a lot less material when compared to lens, mirror and prism based CPV modules, and even many silicon panels. Less material means lower module weight and more affordable panels.

  • is made of acrylic, aluminum, and glass – all low-cost, high volume, global commodities. Our success will not drive up the cost of our materials, as thin film panel manufacturers will as they consume more of the fixed global supply of tellurium. Tellurium is an extremely rare metal found as a byproduct of copper mining (mining 500 tons of copper ore typically yields one pound, or 0.45 kg, of tellurium).
  • is manufactured using simple, automated processes, at globally available manufacturing facilities, such as those equipped to make an automobile headlight. In contrast, thin film and silicon PV require new, high capital cost, clean-room factories. Further advantages of leveraging existing manufacturing infrastructure include:
    • putting to use a huge network of underutilized manufacturing facilities.
    • creating jobs near the sites where our panels will be installed, benefitting regional economies.

Sealed optics coupled directly to the PV cell prevent moisture damage and optical misalignments

The Sun Simba:

  • Our optics are attached direclty to the PV cell and are designed to expand and contract without causing problems.
The Sun Simba Other Concentrating PV Systems
Our optics are attached directly to the PV cell and are designed to expand and contract without causing problems. may have reduced performance due to thermal expansion. As housing materials heat and expand, their different expansion rates can cause optical misalignments, downtime, lower efficiencies and potential module damage.
Our solid system, combined with the Staggered Row design, dissipates heat without such systems, eliminating their costs. require expensive valve systems to solve the problem of thermal expansion.
Our solid system prevents moisture build up in the cell housing, and the associated damage can have moisture build up in the housing, causing damage.

The Sun Simba will operate between 26% and 30% efficiency

The Sun Simba:

  • leverages the latest in high efficiency, multi-junction photovoltaic cells, also called III-V cells. The Sun Simba is a platform to harness these cells as cell technology improves.

  • concentrates up to 1000 suns, with the potential for higher concentrations.
  • made of highly efficient concentrating parts only. There is an absolute minimum of sun-exposed surface that isn’t capturing light, and very few losses in the optics, so the system functions at or near the theoretical limits of efficiency for solar PV systems.

Passive thermal management

The Sun Simba:

  • blocks infrared radiation (IR) and prevents it from reaching the PV cell. The small loss in power as a result of blocking IR is compensated by the cooler cell’s higher efficiency.

  • is designed to allow the panel to be cooled by convection; hot air escapes up and through vertical air spaces in the solar modules. By arranging the spacing vertically, in a Staggered Row, no dead space is introduced on the sun-facing surface.
  • remains well within operational limits, even in critical conditions (-50° C ambient air temperature, 850 W/m2 of direct sunlight, 0 wind, 0 humidity).

Staggered Row design cuts downtime due to wind loading and lowers tracker costs

The Sun Simba:

  • by significantly reducing wind loads, can be mounted on lighter trackers, thereby lowering material costs and shipping costs. Wind loading is more important than panel weight when designing trackers; high wind loads require extremely heavy duty trackers.

  • will have less downtime and lower maintenance costs due to high winds.
  • reduces wind loading by up to 60 % (as predicted by models of our Gen 1 panels, operating at 70 km/h (43 mph) winds).

Sun Simba Panels:

  • are recyclable with high recovery values at the end of their 25 year expected lifespan. Almost 100% of panel materials – which include aluminum, acrylic, glass, copper wiring and multi-junction cells – are recyclable.
  • are non-toxic, don’t react with water and will not contaminate sites in any way.
  • are mounted on sun tracking systems that allow for dual use of the land (as in the image above), and that minimize environmental impact.
  • will offset a significant amount of greenhouse gas emissions. 10 Megawatts of Sun Simba modules (the equivalent of a small solar farm) will offset up to 3,470 tonnes of carbon dioxide a year (based on Ontario Electricity Emission Factors).

How it Works | Morgan Solar

The LSO is a thin optical structure made from simple acrylic and glass components that internally traps and redirects sunlight, concentrating it onto a small, high efficiency photovoltaic cell attached at the optic’s centre. Designed to capture and concentrate sunlight – not the image of the sun – the need for focal depth and the related bulky enclosures of competing Concentrated Photovoltaic systems are eliminated.

Overview | Morgan Solar

Built using fewer, simpler materials – acrylic, glass, aluminum, and a sliver of a high efficiency PV cell – and well-established manufacturing processes, the Sun Simba will generate electricity at significantly lower costs than existing solar panels, while converting sunlight to electricity at efficiencies on par with industry leaders.
