A solar plant typically meets 20%-26% of your total energy requirement. However, this depends on the space available to set up the plant.

PV, short for Photovoltaic, derives its name from the process of converting light ('photo') directly into electricity (‘voltaic’). Simply put, a Solar PV system is a power station that generates electricity from sunlight. The main components of a Solar PV system are:

Solar Panels/Modules: Solar panels consist of a group of small cells made from semiconductor material. When the sun’s light falls on the modules, it excites the electrons, thereby creating direct current (DC).

Storage Battery: The best use of solar energy is to consume it while it is being generated. If the requirement is to store this power and consume it in the non-sunny hours, then solar energy can be stored in batteries for later consumption

Solar Inverter: The DC electricity goes into an inverter that converts it into alternating current (AC). We use AC for running our household or office or factory equipment.

If you planning to install a solar plant, below are some things to consider:

• What are your energy demands? How do you consume the power?
• What is the availability of the shadow free area in your building?
• What is the business model you find more commercially viable (CAPEX or RESCO)
• What would be the savings if you go solar?

• CAPEX
• RESCO or OPEX

There are two main models:

OPEX Model – In this, the investor owns the asset (Plant). The consumer and the producer enters a PPA (power purchase agreement) for a decided duration of time which is typically 15-25 years. During the tenure of PPA, the consumer pays the producer for the power generated at a decided tariff. After the PPA terminates, the asset is transferred to the consumer.

CAPEX model – In this, end consumer owns the asset (Plant) and can claim accelerated depreciation.

The Solar plant will generate electricity only during the Sunny hours, typically between 6 A.M. to 6 P.M and will not generate any electricity during the night. You must source electricity from Grid or the DG set during the night time.

There are various factors involved in choosing your PV system. You might want to research on them before choosing the apt model:

• Energy Consumption Pattern
• Power Cuts or outages
• Various Govt. Policies like Net Metering, Grid Power Access or subsidies on Solar power.

If your roof is not having any shade from any adjacent buildings, trees etc. and its structure is not delicate then your roof is suitable for solar plant. Solar plant can also be installed on car parks, open shade ground within your premises by erecting special mounting structures.

Net Metering allows you to sell excess solar power back to the grid and thus results in maximizing the savings of the solar project.

The plant will generate electricity only during the day time so during the night the electricity has to be sourced from the Grid. Secondly, solar electricity will meet only a part of your total electricity requirement, the remainder of which has to be met from the Grid.

Below are the approximate costs for a 100KW set up:

• Rs. 65-75 lacs for household sector
• Rs. 55-65 lacs for larger commercial & industrial sector
• Utility scale is even cheaper owing to economies of scale

Solar power is much cheaper than power from diesel generators. Today average power from solar is Rs. 5-7 per KWh (Fro commercial and Industrial segments) while average power from diesel generator is Rs. 17 per kWh (a litre of diesel generates around 3-4 kWh).

It can range between 2-10 weeks depending on the complexity of the project.

No permissions are required if you are installing an off-grid solar PV system. But in case you wish to integrate your solar system with grid to avail net metering option, certain permissions are required to be taken from the discoms

This would depend on various factors such as shading free rea available, direction of the roof etc, however as a thumb rule, the following could be a good approximate: 1KW plant requires 12 sq mtrs of shade free area.

On an average, every 1 KW setup produces 1300 to 1500 units in a year. This may however vary based upon the location of the plant, seasonal factors, surroundings and shadow free areas. You can consider 1400 units for sake of calculations.

Solar Power is an intermittent source of energy depending on irradiation, temperature and a lot of other environmental features. Hence, 100 kW plant won’t produce 100 kW power.

Most panel manufacturers give warranty of 25 years, however there have been plants in operations for 40 years as well

The Maintenance is not significant. Water can be used to clean the panels – Typically 5 litres of water is required for a KWh.

The electricity generation of the plant suffers during Rainy and cloudy days especially during the Monsoon season, but the generation never drops to zero. The loss of generation during monsoon and other rains is already adjusted in the 1.3 to 1.5 Lakhs unit/100kWp/annum generation number.

It is advisable to install a data monitoring device along with your solar device that will allow you to compare the actual with the estimated performance on daily, monthly and annual basis.

Solar energy is integrated into the LT panel of consumer premises, wherein DG, Grid or other generator source would be feeding power as of now. When solar energy is injected, the equipment is unaware of the source from which power is feeding in. Hence it is not possible to segregate the loads on basis of power source.

In case the grid fails, the solar power must be fully utilized or stopped immediately feeding to the grid so as to safe-guard any grid person/ technician from getting electrocuted while working on the grid for maintenance etc. This feature is called "Islanding Protection".

Amplus Solar is a dedicated distributed (rooftop) solar power developer catering to industrial and commercial clients.

Amplus works on OPEX model or RESCO model:

1. We set up on-site solar power plants (on rooftops, as carports, on grounds and/or on superstructures). These plants integrate seamlessly with the clients’ existing grid and/or DG system
2. The solar plants are set up entirely on our own cost and are also maintained by us throughout the project term.
3. Amplus enters into a long term (15-25 years) Power Purchase Agreement (PPA) with its clients. At the end of the PPA term, the plant is transferred free of cost (usually INR 1) to the client.
4. As the minimum life of the solar plant is 25 years, the client usually enjoys at least 5-10 years of free electricity from the solar plant.
5. The electricity price for solar power is agreed for the entire PPA period at the beginning of the agreement. This price is always lower than the client’s existing grid tariff, ensuring continuous savings to the client throughout the PPA term.
6. Amplus bills its clients every month on the basis of actual energy generated by the solar plant. This ensures that the entire performance risk is borne by us as we only get paid for what we generate.
7. We ensure that our solar plant has a 99%+ Uptime
8. We undertake stiff plant performance targets and agree to compensate the client if such targets are not met.

Listed below are core strengths of Amplus. This makes Amplus stand out among its counterpart:

1. Solar expertise: Amplus is run by experts in the power sector. We are among the few companies that have end to end in-house capabilities across all aspects – including Design, Engineering, Procurement, Construction, Monitoring and Maintenance.
   
   
2. World class organization: We follow global best practices across Products, Process, Technology and Safety
   
   
3. Rooftop focus: We are entirely dedicated to the distributed (rooftop) sector – this has given a unique advantage in understanding this space as compared to other leading players. For most others, the rooftop segment forms a very small percentage of their overall business, not allowing them the focus required to address the unique challenges of this sector (grid scale and rooftop plants differ immensely in terms of issues and challenges).
   
   
4. Strong Financials: Amplus has an equity investment of US$ 150 million from I Squared Capital, a US based PE fund that focuses on Infrastructure. This translates into quick implementation without the need for third party investors.
   
   
5. Agility and responsiveness: With our quick turnaround times – from capacity analysis, commercial proposal, site specific customization etc. to our speedy, committed-timeline implementation, Amplus ensures that the Customer is at the heart of the organization. Our high repeat rates bear testimony to our customer service orientation
   
   

Generally, the asset is transferred to the client at nominal value. However, this will vary depending on the final commercial agreement between the client and Amplus.

Amplus sells the Solar electricity at a price ("Solar Tariff") which is lesser than your current cost of power from Distribution company and Diesel Generator Backup set. With no startup Capital investment from you, systems start paying for itself immediately and as the gap between solar tariff and the Distribution company power cost increase over the years; the savings also increase.

To install solar power systems on Individual residual rooftops, one must consider the following:

• What are my energy demands? How much power do I consume? This can be analysed from your electricity bills.
• What is the availability of the shadow free area in my building?
• What are the state electricity board regulations of my state?

Usually the capacity of a plant for residential usage comes to less than 50 KW.

Amplus does not cater to smaller plant sizes as RESCO model is not commercially viable. However, there are other EPC players who do cater to this segment. To learn more about this, you can visit :

Solar plants by Amplus are suitable for Business and Domestic establishments alike. We have clients ranging from Industries, Educational Institutes, Hotels, Hospitals, Malls who have adopted rooftop solar solution.

Yes. Amplus can structure the tenure of PPA and tariff as per requirement of customer. The Solar tariff can be flat over the tenure or escalating or combination of flat & escalating or any other customized tariff stream.

Amplus at its own cost takes the complete responsibility of taking all the necessary regulatory approvals and permits required for the operation of the solar plant.

Yes. Amplus obtain all necessary insurance policy which meets the prudent framework of project insurance. Amplus avails comprehensive construction Insurance and Operations Insurance. Amplus complies with all statutory requirements including workman compensation policy. Additionally, Amplus takes insurance of significant sum insured towards third party liability.

Projects will be owned by the company "Amplus Solar" for the tenure of the project.

Our Installation size typically start from around 100 -200 KW.

A proper evaluation will be done by Amplus to see if solar project can be put up on your premises.

Amplus uses non-penetrating structures which are mounted without any puncturing. Thus, the integrity of roof is maintained. The load of the entire solar plant is about 10-15 kg/square meter and can easily be taken by any roof.

No, the system offered by Amplus does not have any battery so the electricity which is generated by the plant should be consumed simultaneously. Since the electricity is not stored, the plant cannot be used as a battery backup.

Amplus offers a Grid Interactive Rooftop Solar plant which matches the frequency and voltage of your Grid and Diesel Generator and runs in sync with them. The electricity created by the solar plant is exactly like the one you are sourcing from Grid/DG and it will be fed in simultaneously with them. Thus, there will be no voltage fluctuations and you can use/connect any number of heavy loads equipment.

Below are the basic requirements Amplus needs to assess the generation capacity based on availability of space and load demand:

• Company Details/Deck
• Location of the roof/ground (Latitude and Longitude on google map)
• Electricity bill for last 3 months
• Contract Demand
