Although the solar energy is a form of enabling green environment, what I implied with the statement is their intention wasn't for green community.
They selected the cheapest form of generating electricity. The building is a commercial building with different shops. Each shop owns its solar system with a 1KVA system around $535 compared to petrol or diesel generator that can go for $200 and above. Then you factor in daily petrol or diesel cost that can amount to $120 monthly.
They selected the best for them and with installmental option, it all makes sense.
