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

1) Is tax credits (33.98%) applicable for commercial roof-top systems
or only for MW projects?
2)Can the depreciation be claimed on O&M expenses, transportation cost, fabrication, civil cost etc.
3) Can a consumer apply for 80% AD and 5.28% of book depreciation,both?
Kindly help me in resolving these doubts

I want to about the solar inverter.
what is the percentage it uses energy of solar.how is it effictive tha normal inverter, and in which state it is use more …tell in percentage,,,which country are using it.
what its scope and uses…
is it possible for poor people
please, send me some link or notes about above mentioned..

How it can help save on electricity bills?
Solar and renewable energy are quite popular these days. In this article, we are providing most of the details one can have questions solar water heater is a system that utilizes solar energy and the energy from sun light to heater water and store it in its storage tank . Its heating process is completely depends upon and electric power is required to heat the water with zero power cost. Solar water heating mainly categorized into two parts i.e.
FPC (Flat Plate Collector)
ETC (Evacuated Tube Collector)
FPC are metallic types system with a longer life.
ETC are made up of borosilicate glass and are fragile.
How to decide on which type to buy?
ETC are fragile with a cheaper price. They are mainly suitable for colder areas where the temperature is sub zero.
FPC are long lasting because they are made up of metallic they are experience than etc they can also work on colder regions with sub zero temperature but this will need an anti freeze solution which makes the system temperature.
How does the system perform on rainy/ cloudy days?
Most of the people thinks that solar system will not work on rainy and cloudy days. Well a system can still work if the overcast is not long ( less than a day or two), as the system works on the diffused radiation in the atmosphere.
A solar system can also be integrated with one existing electric system that can act as a back up during the days when the overcast is long. You can switch on if the water temperature from solar water goes down below 400 C.
