What Should Businesses Consider When Choosing Solar Street Lights for Large Outdoor Areas in India?

Hello everyone,
I am looking for information about solar lighting solutions for large outdoor areas such as industrial parks, highways, factory premises, warehouses, and commercial parking spaces.
Solar lighting can help reduce dependence on grid electricity, but choosing the right system requires careful consideration of brightness, solar panel capacity, battery backup, weather resistance, and maintenance requirements.
For businesses planning these installations, what factors should be considered when selecting a reliable Solar street light manufacturer in India? Is it better to work directly with a manufacturer or purchase through a Solar street light supplier in India?
I would also appreciate recommendations on how to evaluate a Solar street light company in India and compare specifications offered by a Solar LED Street Light Manufacturer in India.
What has been your experience with solar lighting for large outdoor spaces? Any practical suggestions would be helpful.
