Hi all, Our apartment association is considering going for partial solar solution to meet its needs and below is our requirement – Our monthly association EB usage is around 700 units. We are looking at installing a 2.5 KW solar system (with hybrid inverter) that will help us eliminate day time genset backup during summers. We would like this system to supply to 2 fans connected in each of 15 flats in our apartment to the common (association) EB grid. We would like to explore the feasibility of net-metering since beyond the backup, we have scope to route back to the grid and save on costs – esp. since we are falling in the highest slab of EB tariffs. Our association EB connection is a 3-phase system that supplies for a lift, motor and common lights. We are not looking for battery bank backup because of the above exclusive day time requirement. Location: Hyderabad, Andhra Pradesh Some questions we have are: 1. We are assuming that ‘Islanding Protection’ will ensure that in scenario of grid-failure or load shedding, our solar system would still be active within our apartment for the select points we have planned for. Is this a correct assumption or is it total shutdown/blackout if the grid fails? 2. Is the above setup feasibile with net-metering? Esp. since our solar generation is partial and is required to meet the daytime backup for select points (for which wiring is already in place – for genset backup). We only want to avoid daytime genset backup and save on the cost – esp. during summer load shedding. 3. Is the 20% AP state subsidy announced only for net-meter or is it for the entire system? Is this subsidy available for off-grid solutions as well? 4. MNRE indicative costs are way less than what it practically works out!! MNRE guideline cost for a SPV system without battery is Rs.100 per watt. 2.5 KW (without battery) guideline cost = 100*2500 = 250000 After MNRE 30% subsidy = Rs.175000 If AP state subsidy of 20% is applicable = Rs. 140000 I have since enquired with three top companies and I am getting quotations raging from 3Lakhs to 3.5 Lakhs!!! And this is post subsidy, which is makes it almost twice the guideline cost!! Am I missing something or is there plenty of scope for negotiations :)? Thanks in advance for you expert opinions/suggestions. Thanks & Best Regards, Srinivasan M

I would like to understand how net energy meter would supply generated units back to the grid when there is grid shutdown or transformer supply goes off? Please elaborate on how solar generated units would be utilised?

I wish to set up a small scale solar power plant but I don’t know how to start, who I should approach. What capacity of the plant should be ideal for a beginner and kindly guide me through the overall process and also what would be the expenses and break even point duration.

I want to know the efficiency of the basic “Saurya brand” solar cells used in the solar cell arrays. I also want to know their usable life and what happens to them in time. It will also be nice to know the smaller solar module building block size, their output voltage and power rating along with efficiency details and some reference for the MRP cost involved.

We are at Emirates Consultancy Group, would like to fix our first solar AC as experimental attempt, therefore, we have AC unit (24K BTU)from the US but we need to buy solar panels in total of 3.2 Kw with inverters. Could you advice us for the cheapest and good quality which we can buy, please? Suhail
