India is on the brink of solar revolution. Petrol pumps, banks, colleges, offices, urban homes, hospitals, military camps and even entire villages are going solar.
While in some cases going solar is an ethical choice for rest it is a need. However a strong case emerges for all educational institutes and office establishments in Indian cities – they must install grid-tie solar and here’s why…
Why it makes sense to install grid-tie solar?
Operational Hours of Educational Institutes & Offices
All educational institutes and offices function during the day i.e during sunshine hours. Grid-tie solar system is perfect for such places.
The system makes solar electricity in the presence of sun and is connected to a grid-tie inverter which converts DC electricity generated from sun into usable AC electricity so all connected electrical equipment run directly on solar.
It is a battery-less system so it can’t store the excess energy to be used after the sun sets. But schools and offices need very minimal (or nil) electricity in the evening – their major load runs only during the day!
It has been seen that offices, schools and colleges get huge electricity bills because often times electrical load such as lights and fans remain constantly on.
Now that schools and offices can’t do without computers, additional load of running many computers is added which translates into BIG electricity bill! Grid-tie solar system can be a savior here.
It can cut their electricity bills into half or even bring it down to zero. Why? Because you consume FREE energy that solar panels make when sun shines bright on them. You only end up paying for any additional electricity you take from the grid.
Availability of Terrace
Most of the schools have spacious premises including terrace which is ideal for rooftop solar installation. While not all offices may have access to a large terrace, many of Government offices do. The big shadow-free area on terrace makes solar installation quite easy and effective.
Solar Schools for Swachh and Green Bharat
Schools nurture young minds – the future of India. By going solar, schools can send a powerful message and inspire millions of students to support green energy to make our India Swacchh Bharat.

Grid-tie solar system: main grid supply and solar energy together
While there are many remote villages and town in India that struggle with unreliable electricity supply, on the brighter side the power situation in Indian cities has improved significantly.
However the cost of electricity is on the rise. It makes sense to use grid-tie solar because while it depends on good grid supply (it is connected the grid), it caps the rising electricity cost. It is possible to recover the cost of grid-tie installation in just 3-5 years!
List of schools, colleges and offices gone solar and how much do they save?
- 1.3 MW grid-tie solar system at Punjab Engineering College runs college’s 50% of total load and makes an annual saving of 1 crore.
- In Gurgaon, 100 KW solar installation at State Bank Academy makes 1,40,000 units of electricity annually which amounts to Rs. 3 crores in savings (over 25 years).
- 50 KW system at Delhi Board and 70 KW for NHPC generates close to 90,000 units of electricity per year which helps these offices save around Rs.7,20,000 annually and more than 1 crore in 25 years – on an average the life of solar system is 25 years.
