If you’re planning to install rooftop solar panels for your educational institutions, such as schools, colleges, universities, and training institutes to reduce electricity bills or power backup solutions, but you have the basic questions, “how much will it cost?” Solar Rooftop System prices depend on the size of your system, the type of equipment you choose, and the state that you live in, but checking the cost for a 25-kilowatt (kW) system is a great place to start for many business owners. Learn more about how much a 25 kW solar system costs, how much electricity a 25-kW system will produce, and the smartest way to buy solar panels.
How much does a 25-kW solar system cost?
As of October 2021, the average cost of a solar power system in India is 40,000 to 1,00,000 per kilowatt – that comes out to 10,00,000 to 25,00,000 for a 25-kilowatt system. That means that the total 25 kW solar system without battery cost would be 10,00,000 and the solar system with battery bank would be 25,00,000 includes all costs.
How much electricity will a 25-kW solar system produces?
The amount of electricity your solar panels produce depends on many factors, including the direction and angle of your roof. The most important one is how sunny it is where you live – for example, a 25-kW system in India (North, South, East & West Regions) generates 1500 * 25 = 37,500 Units annual.

Installation Best Practice
Step 1: Site Survey
Site survey is an important step as it helps the technician gauge the round whether it is suitable/strong enough to hold the solar system structure. If the roof does not have the required strength, it is advisable not to install the solar system there.
Step 2: Solar System Components
Different components of a 25 kW solar system are solar panels, solar inverter, solar panel stands, solar wires, Installation accessories like nut, bolt, fasteners, etc., net metering and monitoring devices.
Step 3: Installation
Panel Stand, Solar Panel, DCDB/ACDB, Inverter Battery, Earthing Kit, and Grid Connectivity, Load Testing
Step 4: Cleaning & Finishing
After installation is completed, the whole system and area are cleaned for the finishing touch.
Step 5: Customer Feedback, Installation Photographs/videos
After our work is done we encourage customers to share their feedback, with photos and videos as testimonials and future reference.
Maintenance Tips
Annual Maintenance Cost is post-installation work that requires better performance to meet maximum return on investment. There are many local AMC company/installers that they provide this work. The cost of AMC per year is approx. Rs. 1 per watt. Here are some basic guidelines for large projects, such as:
Do:
Step 1: Cleaning Solar Panels, inverter battery
Step 2: Keep inverter battery in an open area
Step 3: Check the water Level of batteries, if you have installed a lead-acid battery
Step 4: Run 50% load of inverter capacity
Step 5: Check Nut Bolts of solar panels and panel stand
Step 6: Run all heavy appliances during the sunny hours (11 AM to 3 PM) only
Step 7: Set SGB (Solar Grid Battery) Profile in Inverter
Step 8: Protect Solar Panels from stone, bricks, very high wind, etc.
Step 9: Battery water level every 3 months.
Step 10: Solar Panels (15 days by ruler area) / (7 days by road)
Step 11: Battery wire in carbon (3 to 4 months) hot water
Step 12: Check cable tie in 2 yrs.
Step 13: Check solar panel performance
Step 14: Check DCDB Fuse every 3 months
Step 15: Switch off the solar system during the solar panel cleaning
Don’t
Step 1: Don’t Run 80% load in morning, evening & night time
Step 2: Don’t change Inverter Setting
Step 3: Don’t change solar panel wiring
