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 want to ask you what exactly does a Solar EPC company in India do? Why most firms are into EPC and not residential and whats the scope of work done in EPC, do they take only MW scale projects?

Electrical energy is the basic need today, and its demand is increasing all over the world. Also, the need for an alternate source for energy has gained importance, and as solar energy is renewable energy backed with the government’s ambitious green energy targets, it has become a major attraction for investors. Over the last decade, countries like China, Germany, and the USA have come up with solar powerhouses and increased the production of electricity by solar energy, which in turn has helped the solar panel market to grow.
Based on type, the solar panel market is segmented into the monocrystalline panel, polycrystalline panel, and thin-film panel. Based on the application, the solar panel market is divided into solar photovoltaic (PV) power plant and solar concentrated power plant. The solar PV panels dominate the market due to low operating costs with it. Based on end-user, the solar panel market can also be segmented into residential, commercial, industrial, utilities, space & defense, and others.
The major market driver for the global solar panel market is the increasing demand for clean energy around the world. Many countries are now shifting towards the sources of clean energy. With the provision of government incentives and tax rebates over the installation of solar panels, the market is expected to undergo exponential growth.
The key market restraint for the global solar panel market is the high cost of installation of the solar panels. A certain area of land has to be given for the installation of the panels, the required amount of area increases with an increase in the amount of energy required. Post-installation of panels, the area cannot be used further for any other purpose, which acts as a restraint in the growth of the solar panel.
The global solar panel market has been spread into North America, Europe, Asia Pacific, Latin America, and the Middle East and Africa. Asia-Pacific dominates the solar panel market and has the largest installation of solar energy. China is the largest producer of solar panels and photovoltaic energy in the Asia Pacific as well as in the world. Governments in India and China are promoting the use of solar energy, and it has positively influenced the solar panel market. Germany is the largest solar energy producer in Europe followed by Italy, the United Kingdom, Spain, and others.

I bought a simple solar set from Amazon about three years ago : two 15W panels, a solar fan, a light and a box. the box has two 12V batteries (Exide). As the batteries did not hold long anymore I replaced them about 2 months ago. For about a month that worked great : the fan and a light both worked during the day and the whole evening. But lately the fan stops already around 5pm. What can be the reason?

I did some research here and there and i dont seem to find the ideal solution for me.
I live in Aizawl,Mizoram. The state electricity board supports Net Metering. Every time there is heavy rain, the electricity board cuts off electricity for safety reason (the infrastructure is very poor here in the hilly region). Moreover there is constant repair work going on every other day, making electricity extremely unreliable. An inverter is a default standard equipment in all homes here!
So what we want to do for our new house is install a 10 KW ON-GRID Solar System with Net Metering enabled, which helps reduce overall cost of our electricity, and also need a power backup system with 20-30 batteries to provide us electricity during the frequent electricity cut offs. The batteries should work only when the electricity board cuts off the electricity.
Can anyone provide me links to the dealers and the equipment i will need as well as the estimated cost?

I have Sukam Falcon Plus 12v Inverter and normal 150Ah SuKam Bazooka Tubular battery.
I wish to install 500Wh Solar panel.
In online, found solar panels with 100W, 250W, 360W and 12V, 24V, 48V.
My question is , can I connect any solar panel to my Inverter? Will sukam falcon plus has any restriction on that?

I want a solar system that can charge my battery a little(20% of the power) and supply the rest of the power to my house(80%) during the day. In the day if there is no power consumed , or less power consumed ,I wanted to send that difference power to the grid.
In the night ,I wanted to completely rely on my battery.
I wanted to know if there is any type of solar system that can suit my needs?
An important thing: If something goes wrong with the system or my solar system do not give enough output , can I rely on the electricity department to supply me normal electricity?
I apologise for the lengthy summary , I’m not very experienced with this.
Thanks a lot, in advance!
