"I want to install a simple solar PV system in the rooftop of my house. How do I go about it??"

This is the procedure for a simple system with Net-metering and no Batteries.
Step 1: calculate rooftop area in Sqft or Sqm Say 100 sqm++
of shadow free area. You need to own the rooftop.
Thumb rule: 1kW needs 10 Sqm/100Sqft
In our case, we can build 10 kW. You need own the rooftop.
Step 2: Check Ebill: say the consumption is 1500 units (kWh)/month. In India, peak sunshine hours = 5.5 hours. In order to++
zero your ebill, you need 1500/(30 x 5.5) = 9 kW system.
Step 3: Check sanction load in ebill. You solar size cannot exceed this value.Say sanction load = 10 kW
Step 4: Choose the min of the values in 1, 2 and 3 and that is the size of the system. In this case,it is 9 kW++
In a 9 kW system, you have about 28 numbers of 330 Watt panels. The number of panels should always be even.
Step 6: Find a place in your house to mount the inverter,covered for rain and sunlight.
Step 7: 1 kW costs about INR 60k. For our system, the cost will++
Step 8: The 9 kW system will generate about 50 units (kWh) per day, which is approx. 18,000 units a years. Consider the residential rates of 8 rs per unit, you save 1.4 lac rupees in your ebill. The ROI comes to approx. 4 years. This is for a ongrid solar system, with net++
metering, without batteries.
Step 9:The first step is get hold of a Solar EPC company near your place and get a quote.
Step 10: Then you have to apply for net metering at the electricity provider office in your district. Check your ebill. ++
Step 11: Once your get the clearance for net metering, ask the Solar EPC to come and install and commission the system for you.
Step 12: After system is commissioned, shut it off. Intimate the DISCOM/electricity provider and get a date for net metering installation.++
Step 13: The DISCOM will come and install the net meter and commission the system. Ask your EPC person to be at site as well.
You can started saving on electricity immediately and do your bit to fight #ClimateChange
This is only valid for India.
When you generate excess++
electricity from the sun, you can send it to the grid, store it and then take it back when needed.All the accounting is done by the net-meter which is a bi-directional meter. Use grid as your battery.Use Tier1 panels, good quality inverters, you should have a good system.🙏🙏
