Solar installation quotes in India often look lower than the final bill because essential items like mounting structures, cables, surge protection, and grid approval fees are excluded from headline prices. When comparing quotes for home solar systems, looking at single lump-sum figures can be misleading. Differences in panel technology, cable lengths, civil work, and net metering charges often account for major price gaps between installers. Understanding these overlooked components allows homeowners to demand fully itemized quotes, preventing unexpected expenses during or after system commissioning.
