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 am an IIT student. We are studying regarding the smarter energy solutions. I see some two-wheeler vehicals available in market running on battery. We are interested in the vehicals who has battery 48V and 3A and battery type is SLA 48V/20 AH. If we want to charge this vehical completely in 5-6 hours using solar panels, what would be the cost and in what size solar panels will be required? Consider overall environment conditions of india. Give me as much details as possible so I can understand easily. Thank you.

My name is Ravi.
I am planning to construct a farm house of an approximate plinth area of 2400 Sq.ft.
I cant get any electricity from the corporation. I want to use Solar Panel to cater my electricity needs.
I used your energy Load and size of solar system calculator which is a brilliant tool.
Energy Load required is 1500kW
Solar System Size Required is 5.4kW.
Can you please advise me on the feasibility and the costs.
I am emailing from the UK, my mobile number is .
The farm house will be in Hubli, Karnataka, India.

Hi ,I am new to this forum and hope that I will get all my doubts resolved here.
Let me tell the details of the product that I purchased.
I have a 1000Va Su-kam home ups system using two 24 V batteries.To this system I want to connect 2 X 200W (24V) solar panel(Moserbaer MBPV200P) in parallel.The distance between the inverter and the solar pannel is approximately 15 Meters. tHE SIZE OF THE SOLAR PANEL IS APPX 5.5 FEET x3.5 Feet each.
Q1.What should be the thickness of the wire that I use to install this system.
Q2.I live in auraiyya (UP)(26.4700° N, 79.5200° E) what should be the direction and the angle from the ground at which I should install the panels.
Q3.Should I prefer adjustable or fixed mount for the panels.In case of adjustable mount what should be the tilt of the panels in different months.Also please mention the same in case of fixed mount.
Q4. Do I need MC4 connecters or twisting the wires together will do the job.
Thanks a lot for your help.

sir,i want to install a grid tied system in a commercial complex. Loads vary from cfl to air conditioners. my question is what happens when there is no grid power, will there be a total blackout or the solar will keep on supplying?
If i connect solar grid tie system to the small loads(lights bulbs, fans and etc) and supply grid power to higher loads such that solar power is enough to meet the requirement of smaller loads at any time. In this situation if there is no power in the grid, will my whole system shut down or the smaller loads still remain alive ?

My name is Tarun and I’ve started a Solar Company along with two of my friends. My question is “what certifications and approvals we need to go through for doing Solar Installation and Trading(buying products from manufacturer and selling it to end customers)”.
