Rooftop Types & Structural Mounting Profiles
Flat RCC Roofs
| Mounting Structure | Ballasted or Anchor-bolted Leg |
|---|---|
| Optimal Tilt Angle | 10° - 15° (South Facing) |
| Wind Loading Limit | 150 km/h |
| Shadow Constraints | Needs Parapet Offset Clearances |
Reinforced Concrete Cement flat roofs represent over 75% of urban Indian rooftop installations. Easy maintenance access but requires structural concrete drilling or heavy ballasts.
Slanted Metal Tin Sheds
| Mounting Structure | Direct Rail and L-Feet Clamps |
|---|---|
| optimal Tilt Angle | Follows roof pitch (flush mount) |
| Wind Loading Limit | 140 km/h |
| Structural Load weight | ~15 kg / m² |
Common in suburban homes and commercial workshops. Mounting is highly cost-effective and fast, utilizing non-penetrative standing seam clamps where possible.
Housing Societies
| Mounting Structure | Shared flat roof framing |
|---|---|
| Metering type | Virtual Net Metering / Common Area |
| Approvals Required | Society NOC + Fire Safety Certificate |
| Sizing Rule | Proportionate to flat ownership |
Multi-family apartment structures require shared area NOCs. Solved using Virtual Net Metering policies to credit individual utility bills proportionately.
Quality Assurance: Tier-1 Testing & IEC Certifications
Photovoltaic panels and grid-tied inverters listed in our hardware registry must meet strict international electrotechnical standards, including IEC 61215 (terrestrial photovoltaic design qualification), IEC 61730 (photovoltaic module safety qualification), and IEC 62109 (safety of power converters). These certifications guarantee robust insulation resistance, resistance to mechanical snow and wind loads up to 5,400 Pa, and verified anti-islanding grid protection.
