What is a solar cell?

A photovoltaic cell or solar cell is a device that converts light energy directly into electricity using the photovoltaic effect. These solar cells are the fundamental building blocks of the photovoltaic panel used to generate clean, renewable energy for a wide array of applications.

Importance of photovoltaic panels

Photovoltaic panels are the primary technology driving the global shift toward sustainable power. Beyond just generating electricity, their importance stems from their ability to address simultaneous environmental, economic, and social challenges.

Climate Change Mitigation

• Low Lifecycle Impact: While manufacturing requires energy, most new solar panel technology reaches carbon neutrality within 1 to 4 years of its 25–30 year lifespan.

Economic Empowerment

• Drastic Cost Reductions: Since 2010, the cost of solar panels has dropped by over 80%, making it the cheapest source of new electricity generation in many regions.
• Household Savings: Residential systems can reduce electricity bills by 30% to 80%, often paying for themselves in 3 to 6 years through energy savings and government incentives like PM-Surya Ghar.

Resource & Health Benefits

• Water Conservation: Unlike coal or nuclear plants that require vast amounts of water for cooling, PV systems use little to no water to operate, which is critical in drought-prone areas.
• Public Health: By replacing fossil fuels, solar reduces air pollutants like sulfur dioxide and particulate matter, which are linked to respiratory and heart diseases.

Energy Security and Access

• Decentralisation: Solar allows for “distributed generation,” where power is made exactly where it is used. This reduces transmission losses and makes the grid more resilient against large-scale failures.
• Rural Electrification: Photovoltaic panels are essential for bringing power to remote off-grid areas where extending the traditional power grid is too expensive or geographically impossible.

Key product lines & technology

Several PV cell series tailored for different applications, from residential rooftops to large-scale ground-mounted solar plants.

• Helia Series: These are high-efficiency modules (400W to 600W) built with M10 MonoPERC half-cut cell technology, suitable for various installations.
• Helia Plus: P-type bifacial modules using transparent backsheets or dual glass, with power outputs of 540-555Wp and efficiencies up to 21.50%.
• Helia NXT: N-type bifacial modules featuring TOPCon technology, offering even higher efficiencies (up to 22.86%) and enhanced performance in low light or high temperatures.
• Helia NXTR: Helia NXTR is a high-efficiency N-type TOPCon solar module featuring advanced rectangular G12R cells that deliver a maximum power output of up to 630Wp. Designed for durability in tough environments, these bifacial glass-to-glass panels achieve a peak efficiency of 23.34%.
