More electricity from your available space, even when real-world conditions are not perfect. SunCore™ is the dependable everyday choice; SunCrown™ is engineered for maximum output; SunCrown Black™ pairs the same technology with a refined all-black finish for premium properties.
Series 01Reliable power for everyday energy savings. LEWIS SunCore™ is our high-output solar panel range for homes, businesses and larger commercial installations. Available from 570 W to 650 W, each panel uses advanced N-Type TOPCon cell technology to capture more sunlight, generate efficiently throughout the day and maintain dependable performance over the long term. Selected for hot, sunny environments, SunCore™ delivers reliable electricity, reduced energy costs and excellent lifetime value.
Series 02More electricity from the space you already have – even when sunlight is partly interrupted. LEWIS SunCrown™ is our flagship high-efficiency solar panel range for customers seeking stronger daily generation, better use of available space and improved performance under partial shading. Advanced N-Type ABC back-contact technology places the electrical contacts behind the solar cells, leaving more of the front surface available to capture sunlight. Cell-level shade optimisation helps the unaffected areas continue generating when trees, leaves, dust, chimneys or nearby structures shade part of the panel.
Series 03Premium design with intelligent energy performance. LEWIS SunCrown Black™ is our high-efficiency all-black solar panel range for modern homes, villas and premium commercial properties. Advanced N-Type ABC back-contact technology moves the electrical contacts behind the solar cells, creating a clean, grid-free front surface with more area available to capture sunlight. Partial-shading optimisation helps reduce generation loss when trees, leaves, dust or nearby structures shade part of the panel, while durable dual-glass construction supports dependable long-term performance.
How Lewis SunCrown™ and SunCrown Black™ use N-Type ABC back-contact technology to manage localised shade and help more of the unshaded panel continue generating.
Trees, chimneys, leaves, dust and bird droppings can temporarily shade a small part of a panel. A small shadow will still reduce output, but advanced cell-level optimisation can keep the effect more localised.
Reduce disproportionate loss from small, localised shadows.
Help more of the unshaded panel continue generating.
Limit excessive cell temperature under localised shade.
Solar modules are built from electrically connected cells. Depending on the module architecture and the position of the shade, one local obstruction can reduce output from a wider electrical section.
Moving shadows can cross different cells throughout the day.
Fixed obstacles may create repeatable shade patterns.
Small obstructions can fully cover a local cell area.
Patchy contamination can reduce light reaching selected cells.
SunCrown™ technology is designed so that a small shaded area does not cause unnecessary loss across a much larger part of the module. The comparison below is illustrative, not an electrical simulation.
Wider section: reduced or bypassed. Exact effect varies with module design and shade position.
More of the unshaded panel continues. Localised shade still reduces output; it is not eliminated.
Shade reaches one local area.
The affected cell contributes less power.
Optimisation limits unnecessary wider loss.
More unshaded area can keep generating.
This visual explains the principle in simple terms. Actual electrical behaviour depends on the exact panel architecture, shade location, shade size, duration, irradiance, temperature and inverter operating point.
A manufacturer-published summary of a TÜV Nord comparison reports that, with one solar cell fully shaded, the tested ABC module generated up to 30% more module power than the referenced conventional technology under the defined test conditions.
up to 30% more module power
with one solar cell fully shaded, versus the referenced conventional technology, under the defined test conditions.
Actual energy generation varies with the selected module, shade size, shade position, shade intensity, duration, system design, irradiance, temperature, maintenance and weather. The controlled result supports the technology principle; it does not replace site-specific design or yield modelling.
A shaded cell can become hotter than surrounding cells. The ABC platform includes high-temperature restriction designed to limit excessive hotspot temperatures, helping reduce thermal stress and support safer, more dependable operation.
Standard bypass-diode protection. No specialised cell-level partial-shading optimisation.
Cell-level partial-shading optimisation and high-temperature restriction.
Cell-level partial-shading optimisation and high-temperature restriction.
Model recurring shade from trees, chimneys and nearby structures before finalising the array.
Keep permanently shaded areas away from modules where possible; select suitable string and inverter design.
Remove leaves, heavy dust and bird droppings safely and at appropriate intervals.
Confirm the exact model, ratings, warranty, installation limits and certification before purchase.
Document status and limitations. This is a Lewis-branded customer information overview, not an independent Lewis laboratory report.

Back-contact cell technology removes front-side metal grid lines, leaving more active surface available to capture sunlight. This supports higher panel efficiency and more installed power within a limited roof or project area.
Cell-level partial-shading optimisation helps limit power loss when leaves, dust, bird droppings or nearby objects shade a small part of the panel. In a controlled TÜV Nord test with one cell fully shaded, both SunCrown™ modules generated up to 30% more power than the reference TOPCon module.*
A power temperature coefficient of −0.26%/°C helps the panel retain more of its rated output as cell temperature rises – particularly valuable on exposed roofs and in hot, sunny conditions.
High-temperature restriction is designed to limit excessive cell temperatures when part of the panel is shaded, helping reduce thermal stress and support safer, more dependable long-term operation.
Copper-based interconnection avoids high-temperature firing and creates strong copper-to-copper connections. This improves resistance to mechanical stress and micro-cracks that can gradually reduce energy output.
Designed for low degradation, with no more than 1% output reduction in the first year and no more than 0.35% annually from years 2–30. Guaranteed performance remains at least 88.85% at year 30, subject to the applicable product datasheet and warranty terms.
*Based on a controlled TÜV Nord comparison with one solar cell fully shaded. Actual energy performance varies according to panel model, shade size, shade position, duration, installation design, temperature and weather conditions.
