Walk into any solar shop and you will hear mono, poly, PERC, TOPCon and bifacial. This guide to solar panel types in Raipur explains what each means for cost, output in heat and long-term value.
Quick answer: for most Raipur rooftops, choose a mainstream mono module (PERC or TOPCon) that meets DCR rules and has strong warranties.
| Type | Efficiency | Cost | Notes |
|---|---|---|---|
| Polycrystalline | Lower | Lowest | Older technology, less common |
| Mono PERC | Good | Moderate | Widely used |
| Mono TOPCon | Higher | Moderate to high | Better in heat, lower degradation |
| Bifacial | Extra from rear side | Higher | Best for open or reflective ground |
Higher efficiency matters mainly when roof space is limited. If you have plenty of roof, a standard module with a good warranty is often the better value. Ask for datasheets and compare like with like. See mono vs poly vs TOPCon.
Prices change with technology and policy. Read solar panel price in Raipur for the broader cost picture.
| Line | What it tells you | What to look for |
|---|---|---|
| Power rating (W) | Output at test conditions | Matches the quote |
| Efficiency (%) | Output per unit area | Higher helps small roofs |
| Temperature coefficient | Loss per degree above 25 C | Lower (less negative) is better |
| Degradation | Yearly decline in output | Lower is better |
| Product warranty | Defects cover | Longer is better |
| Performance warranty | Output guarantee | Clear year-by-year figures |
Premium panels make sense when roof space is tight or when you value lower degradation. If you have plenty of roof and a tight budget, spend on better structure, protection and service instead. A mid-range panel with strong support often outperforms a premium panel installed badly.

Domestic content requirement; subsidised systems need modules with domestic cells.
They help on ground-mounted or light-coloured surfaces but add little on dark roofs.
Commonly 12 years on product and 25 to 30 years on performance, but read the terms.
