Posted on Leave a commentPosted in Knowledge Center, User Story

This week we bring to you a Case Study of our client who has recently installed a Hybrid Rooftop Solar Plant. We thought it best to share his experience with our users and so here is a brief. To give you an overview, this is a Residential Rooftop project with battery back-up. The project was executed at the on-set of Summer 2017.

The project capacity is 2.5kWp (Get your estimate here).


  • Modules: Canadian Solar (315 Wp)
  • Inverter: 3kVA, 48V, Solar Hybrid Inverter, Flinn Energy
  • Batteries: 150 Ah Exide Solar Batteries
  • Structure: Raised (2400 mm)
The project is setup in a rural area where electricity supply is not continuous and power outages can be seen for up to 8 Hours a day. Solar Power for our client was a reliable and clean source of energy for energy security. The system is completely automatic, nothing needs to be done to use this solar power. For maintenance only PV Modules cleaning is required roughly every two weeks depending on the local environmental conditions like dust on panels.

Day 1: Completed the foundations and structure installation.

Day 2: Earthing pits.

Day 3: Batteries, ACDB and Inverter were installed and AC side wiring was completed.

Day 4: Modules, DC distribution box were installed and DC side wiring was done.

The project was commissioned on the fourth day on April 3, 2017.

User Experience:

Was your Solar Power Plant appropriately sized?

From what we have seen in the last two weeks that Solar Energy is sufficient to take care of energy requirements. We haven’t seen the instance where batteries are discharged to a level where power from the grid is required to charge the batteries and meet the load requirements.

What has been your experience so far with solar?

Our experience has been very good. Now we have continuous (24*7) and clean electricity at our home. It’s not only visually appealing but high quality performance system. This has been much better than what I had originally expected.

Would you recommend it to your neighbours?

I would strongly recommend it to my neighbors and friends. We have friends coming to home who enquire about the project and its performance. I hope these kinds of installations will help in educating the people and adoption of Solar Energy will increase in rural areas.

Did Ezysolare make it simple for you by supplying material on time? How long did it take? 

Ezysolare played an exceptional role in the project right from planning to delivery. It not only helped in buying the items instead Ezysolare took it to next level right from calculating the load profile, generating the Solar Energy Assessment Reports, Techno-Commercial comparisons with the help of Ezysolare platform and ensuring timely deliveries of components. And it all just took three weeks to execute the project right from planning.

What did you have to do apart from approving each step?

The entire process the fairly simple and user friendly. I just approved the order, thereafter Ezysolare team took care of everything procurement, dispatch, sharing the tracking details and exact status of material on a daily basis and arranging for a local installer.

Ezysolare’s moto has always been to make ‘going solar’ simple. With the summer’s here, there would be no better time to go solar, reduce your bills and keep you home/building cool. Send us your query here and we shall be prompt in getting back to you.

If you’ve been in the Solar Energy Industry for the past 3-4 years and you’re beginning to think the excitement of the government might have died for Solar Energy, I’d like to stop you right there. The government has introduced yet another scheme for the Solar Energy sector which is an opportunity for those doing business and affordable & beneficial for the end customers.


Delhi Solar: Group and Virtual Net-Metering come of age this April

Posted on 1 CommentPosted in Knowledge Center

The Delhi Solar Policy was made official in October 2016 before which it was in draft stages. The Policy enables basic advantages such as net-metering mechanism which allows consumers to feedback excess electricity generated from the solar power system to the grid. However, there are a few special advantages in the Delhi Solar Policy not offered by other states.

Delhi Solar

It’s been a while since it was declared that Group and Virtual Net-Metering will be available for those who install Rooftop Solar Plants in Delhi. However, the time has come when this declaration matured to reality.

Solar Rooftop Scenario – Maharashtra

Maharashtra State Net metering policy highlights

Eligible Consumer
  • Wants to setup a Solar Plant up to a maximum capacity of 1 MW (subject to Technical Constraints explained ahead)
  • On Rooftop or any other Mounting Structure (Ground, Shed and Superstructures etc) in his premises
  • to meet all or part of electricity requirement including Consumer catering to common load (Housing Society Community Halls, Pumping stations etc)
  • Such System maybe owned by Consumer directly or by 3rd Party leasing such system (opening up the market to investors who will setup the power plant FREE to sell electricity to the consumer at a cost less than what Distribution Companies offer)
Capacity Limitation (Due to transformers)

The cumulative capacity of all solar plants connected to a Distribution Transformer (which is the closest grid transformer from which we receive electricity) should not exceed 40% of its capacity. The Distribution Company may allow for more after conducting a Detailed Load Flow Study,

The Distribution Company shall:
  • Put on its website, the information of available capacity of Distribution Transformers within 3 months (10th Dec, 2015) of the notification (10th Sept, 2015)
  • Update the capacity available quarterly within 1 month of ending of the quarter
First Come & First Serve

Since there are technical limitations set out in the policy for the maximum capacity of Solar plants that can be connected to the distribution transformer of the Electricity Distribution Company, the permission for Net Metering would be given on First Come, First Serve basis with a priority to already installed Solar Plants.

Duration of net metering agreement

After the approval for Net Metering, but before the commissioning of the system, the distribution company and the consumer would enter into a Net Metering Agreement for a duration of 20 years.

Figure 1-Solar PV Installation Capacity

With rising solar photovoltaic based power development across the globe, there is more competition in the PV industry as manufacturing segment and downfall of various cost component that results in better deployment for solar manufacturing and price cut. Module Pricing Note describes the change in the pricing trends of the solar photovoltaic modules in various region i.e. Germany, East Asia, South east Asia, North East Asia as these market are highly demand oriented. In this analysis note solar PV module cost (INR/Wp) has been covered as Indian Solar Industry is moving with CAGR of 95.60% YoY since 2010 and expected to grow at the rate of 61.67%  YoY in next 6 year. Presently, In solar industry, the most important thing which decides Cost-Benefit ratio of the project is the price of Modules. Instead there are so many other factors also, but the present focus is on modules since the cost of solar cells fluctuates at very higher rate as per the market or demand. The change in $ (share prices) value also effects the INR values and 85-88% of the installation are based on the imports from the off shore companies.
