Solar Irradiance Advantage
The Deccan Plateau covering most of Telangana and Andhra Pradesh receives 5.5–6.2 kWh/m² of solar radiation daily - among the highest in India. For solar street lights, this means: batteries charge fully even in winter. Systems sized for Maharashtra conditions will over-perform in Telangana/AP. Longer backup periods are achievable without increasing battery size. LiFePO4 battery longevity is excellent since temperatures, while hot in summer (45–47°C peak), do not cause more degradation than Maharashtra. The Rayalaseema and Telangana plateau areas are among the best solar street light deployment zones in India.
Government Schemes in Telangana
TSREDCO (Telangana State Renewable Energy Development Corporation) runs solar energy programmes including village solar lighting. The state's Panchayat Raj department funds solar street lights under DDUGJY and PMGSY for rural roads. Hyderabad Metropolitan Development Authority (HMDA) has smart city lighting projects for Hyderabad's outer ring road and township areas. The Telangana government's 'Palle Pragathi' (village development) programme includes solar street lights as a standard village infrastructure item.
Andhra Pradesh Solar Programmes
APERC (Andhra Pradesh Eastern Power Distribution Company) and APSPDCL (AP Southern Power Distribution) have rural solar lighting schemes. The AP government's 'Panta Sanjeevani' and rural development schemes include solar street lighting for mandal roads. Amaravati - AP's planned capital - has extensive smart street lighting in its development plan. AP's ambitious renewable energy targets (24,000 MW solar by 2030) include rural and urban solar infrastructure including street lights. Xera Tech can supply to AP/Telangana projects from Nashik with competitive logistics (direct rail or road freight to Hyderabad: ~600 km, 1–2 days).
Technical Considerations for This Region
Panel sizing can be conservative (1.3:1 panel-to-LED ratio instead of 1.5:1) given the high irradiance - this reduces cost. Coastal AP (Vishakhapatnam, Krishna, Guntur districts): IP66 mandatory due to Bay of Bengal humidity and cyclone-driven rain. Hot summer: panels should be mounted with gap under them for airflow - reduces panel temperature by 5–8°C, improving efficiency. Cyclone wind load: coastal AP is in Wind Zone IV–V. Poles and panels must be designed for 50–55 m/s design wind speed - verify with the manufacturer's structural calculation.
