The sun shines down benevolently on the iconic Mahim Jame Masjid, which recently joined a handful of city mosques that have converted to solar energy. Jame Masjid (which fits 8,000 people) racks up electricity bills of Rs 45,000 to Rs 60,000 every month, and twice as much during Ramzan. But the next bill will be half the amount, hope the trustees, who inaugurated a 15 KiloWatt (KW) solar power generation system on November 21.

The main prayer hall on the ground floor is fully air-conditioned. Thanks to the solar panels, Mumbai's generous sunlight will end up cooling the mosque at half the cost. Fahad Khalil Pathan, managing trustee of one of the oldest Shafai (Sunni sect) masjids in the city, said the project was conceived three years ago.
