Can We Run AC Using Solar

Yes, you heard it right! One of the prerequisites of an on grid solar installation is net metering. Net meter or a bi-directional meter helps in calculating any excess power generated from a customer’s solar system and being sold back to the grid for which the customer gets a credit. However, recently there has been a lot of delay in getting an on-grid system installed because of lack of adequate number of net meters and problems in getting proper approvals and subsidies, which are the major attractions behind installing an on-grid solar system.

Our recent efforts in installing solar panels at hospitals left us with a realization that there are many who are ready to go solar, but are held back due to the stress involved in getting net meters and subsidies. There is a lot of paperwork and bureaucracy involved in getting things done easily.

  

 

Solar Net Meter Technical Feasibility

There are two criteria:

1.      The total solar PV capacity in the local distribution network (existing and proposed) shall not exceed 30% of the distribution transformer capacity. Example: A distribution network that is served by a 250 KVA distribution transformer cannot have more than 75 kW of total solar PV capacity connected to it.

2.      The proposed solar PV system capacity cannot be more than the sanctioned or contacted load of the service connection. If the proposed solar PV capacity is more than the service connection sanctioned load, you first have to apply for service connection load enhancement and then submit your solar net-metering application.

  The Electricity Bill with Solar net-metering

With solar net-metering the Consumer pays for the difference between import and export energy (the net-metered energy). Example: a Consumer imports during a billing cycle 900 kWh (units) and exports 500 kWh. The electricity bill will be for 400 kWh. If the export energy exceeds the import energy, the excess of import kWh will be carried over to the next billing cycle. During a 12 months period (the Settlement Period - The period beginning from first of April in an English calendar year and ending with the thirty first of the

March of the next year) the maximum of energy export that will be credited by State Generation and Distribution Corporation is 90% of the energy import.

Example: During the settlement period there is a total import of 5,000 kWh and a total export of 6,000 kWh. Of the 6,000 kWh exported 4,500 kWh is eligible for adjustment with the import kWh (90% of 5,000 kWh).

Solar Professional’s Overview

Let’s know from the solar enthusiasts…

 Sneha Shah of Greenworldinvestor thinks that lack of easier options to gain access to net meters and hassle free subsidies/ approvals is the need of the hour. “Though the government has made various policies these are on paper only and common man is suffering to gain access to resources such as net meters”. She had recently published an article on her blog highlighting how Delhi NCR is suffering from lack of adequate number of net meters. Vendors confess having customers in hand but the situation is bad because of the unavailability of net meters.

 Mantosh Singh of Khalsa Electricals YouTuber and System Installer says that I approved Net Meter within 30 days of 50 kW Solar System in Uttarakhand, but residential homeowners approve Net Meter self. It will take time approx. 30 – 60 days.

मेरा नाम अनिकेत मिश्रा है मैं यूपी के छोटे से जिले प्रतापगढ़ का निवासी हूँ । मैंने अपने घर के अत्यधिक बिजली के बिल से परेशान होकर (जो कि गर्मी के दिनों में 3000 से 5000 प्रतिमाह के बीच आया करता है) बिल को कम करने के लिए अपने घर पर ऑनग्रिड सोलर रूफटॉप सिस्टम लगवाने का विचार किया जिसके लिए मेरे घर की छत पर पर्याप्त स्पेस, सूर्य का प्रकाश व दिन के समय विद्युत विभाग से लगभग निर्बाध बिजली की आपूर्ति, जो कि ऑनग्रिड सोलर PV सिस्टम के लिए अतिआवश्यक होती है, उपलब्ध थी । - क्या ऑनग्रिड सोलर सिस्टम के लिए नेटमीटरिंग लगवाना आवश्यक है ? यदि किसी कारण से विद्युत विभाग से नेटमीटर नही मिल पाता है तो क्या मैं अपने घर पर ऑन ग्रिड सोलर सिस्टम नहीं लगवा सकूँगा ?

 Similarly, our representative Nishi Chandra says that he receives many queries on a daily basis regarding challenges around on-grid solar installation…..

Today, customers are not very keen on generating excess power and earning a discount on their power bills. Instead, they want to generate enough electricity from their solar system and be independent of the grid during the sunny hours. In the long run, a solar system will anyways generate huge savings for its customer.

FAQs

Here are few very common questions that we receive frequently from our readers:

What is the mounting angle and direction of installing solar panels?

Ans. The mounting angle depends upon your latitude position and the season. It is generally 30 degrees. The best direction to face solar panels is south, since India lies in Northern Hemisphere. East and West directions also work well. North is the only direction that we should not want to put our panels on.

Whether installation of on-grid solar system will damage the roof?

Ans. No, installation of on-grid solar system will not damage your roof.

If I get a solar system installed, will the extra power be purchased by PSPCL?

Ans. Yes, extra power will be purchased according to the feed-in tariff rates of the state provided you have a net meter installed.

Is it possible to install a solar system in Assam for residential purpose only?

Ans. Yes, you can read more details on the Assam government portal.

I want solar panels installed at my place. Can I have a visit by representatives?

Ans. Yes, our representatives can pay you a visit and suggest you accordingly, depending upon your house location, structure of the roof, electricity requirement etc.

Price of 3 kW solar system?

Ans. Off-grid will cost you roughly Rs. 285,000 and on-grid solar system will cost Rs. 180,000.

We have 5 ACs of 2.5 ton each, working round the clock for cold storage. Kindly suggest the size of on-grid rooftop solar system.

Ans. A 2.5 ton AC generally consumes in between 3000 watts per hour or 3 units

Total energy requirement daily = 5*3*24 = 360 units

1 kW generates 3-4 units daily (depending upon its location, efficiency etc.)

Size of solar system = 360/3 = 120 kW

How does the excess electricity go back to the grid? Does government accept anywhere in cities?

Ans. The excess electricity generated by a solar system goes back to the grid in the same way electricity from the grid reaches our homes. This to and from movement of electricity is recorded through net meter installed at the customer’s place. India has adopted net metering in almost all its states.

What is the cost of 5 kW solar system at office for day use only? Tell me the space required for installing the system?

Ans. The cost of a 5 kW system will be approximately Rs. 475,000 (for off-grid system) and Rs. 300,000 (on-grid system) and it needs … square meters area for installation.

I have a rooftop of 400 square feet. I want to install 3 kW solar system. Can you guide me and send the cost?

Ans. Off-grid will cost you roughly Rs. 285,000 and on-grid solar system will cost Rs. 180,000. 300 sq. ft. area should be sufficient.

I have a 3 bhk flat. I would like to install solar panels (on grid). Please suggest.

Ans. You need to specify your power requirement in units or the appliances you use and the number of hours of usage daily. Only then we will be able to better address your query.

Is it mandatory to have net metering for an on-grid system?

If you want to claim a discount in your power bill, only then net metering is mandatory. However, if you are using the electricity for personal use only and not selling it back to the grid, there is no requirement of net metering. Loom Solar has launched an on-grid solar system which is capable of functioning even without net metering.

Can we get subsidy only after getting our solar system installed by installers listed on UPNEDA?

Ans. Yes, you can get subsidy only after getting your solar system installed by installers listed on UPNEDA.

If we cannot get net metering due to which our on-grid system could not be installed, how can we run the big appliances like AC, submersible pumps at home?

Ans. You can install an on-grid solar even without net metering and can run the heavy appliances by installing Loom Solar’s newly launched Solar AC module. We have tested our product and it is running successfully.
