Solar PV

About Solar PV

Solar energy creates clean, renewable power from the sun and benefits the environment. Alternatives to fossil fuels reduce carbon footprint at home and abroad, reducing greenhouse gases around the globe. Solar is known to have a favorable impact on the environment

Solar Photovoltaic (PV) is a technology that converts sunlight (solar radiation) into direct current electricity by using semiconductors. When the sun hits the semiconductor within the PV cell, electrons are freed and form an electric current.

India’s Solar Industry targets represent a major opportunity for Solar PV plants as the demand of electricity is increased day by day. So we needs to play an integral and active role in executing solar projects.

Internals of Solar PV

Solar PV is divided in three parts: One part is On-Grid Solar System, Second part is Off-Grid Solar System and Third part is Hybrid System.

On Grid System: Solar Power generated directly go to LT meter of particularly Discoms.

Off Grid System: Solar Power generated is stored in Battery and from battery we use according to your needs

Hybrid System: Solar Power generated is stored in battery according to consumption use and remaining power generated goes to LT meter.

Working of Solar PV: Solar PV is connected to Inverter. And through Inverter it is connected to LT meter. In between Solar PV and Inverter, protection device called DCDB is connected. Also in between Inverter and LT meter, another protection devices called ACDB is connected.

Net Metering:

Net Metering: It is a billing arrangement that allows the consumer to sell excess energy to the utility company. In other words, net metering takes in to account the difference of energy consumed from the grid and energy feed back to the grid.

Benefits of Net Metering:

Monetary Benefits: Owner get directly reduced in bill amount i.e it get financial benefits
Battery less Systems: Excess energy is directly feed in to main grid and deficit energy is directly drawn from the main grid. This avoids heavy cost of batteries which used our needs.
No Dependency on back Up System: Direct switch between energy sources and no dependency on batteries. So there is no need of depending on backup systems
Less Maintenance: With reduction on backup systems and batteries, maintenance is reduced.

Solar Installation Model:

Zero Investment Model

Consumer required Solar Panels to be installed

Capex Model

Consumer have space and ready to invest

BOOT / RESCO Model

Zero upfront Cost
- With PPA, you don’t need to make any upfront investment, because you are not buying a system in first place.
- You are only buying energy produced by the system
Lower Energy Cost
- The energy price offered in PPA is significantly lower that the grid based energy. That means the more energy you use, more you save.
Zero Maintenance
- We maintain the system for the period of PPA term. You are assured of un-interrupted power supply all the time.
Zero Risk
- If the system doesn’t produce energy (may be on a cloudy day), you don’t have to pay.
Transfer of Ownership
- You have an option to own the system at the end of PPA term and prolong your energy savings.

Operations & Maintenance:

Operation & Maintenance (O&M) is one of the most critical ways to ensure that the solar power system gives the best possible generation. This enables the plant to produce the maximum amount of energy throughout its operational life, perfectly aligning the interests of developers, clients and the investors.

Modules: Modules need the maximum amount of preventive maintenance, and cleaning activities are majorly concentrated around them. In normal conditions, where there isn’t too much dust or dirt, cleaning is carried out on a fortnightly basis. However, in dusty areas such as Rajasthan, the cleaning frequency is increased to once a week.
Inverter: Most German-make inverter manufacturers recommend servicing it on a quarterly basis. However, servicing on a monthly basis is recommended as there is more dust in India compared to other countries. As part of preventive activities, our engineers check the voltage of the string inverter and record it in the periodic log book. This gives an understanding of voltage fluctuations if any.
MC4 Cabling Connector: Any gap, irrespective of the size, could cause a fire and damage the modules. Separately, off-takers can install a “check” meter of equal or higher accuracy with reference to the main meter to cross-check the production level on a monthly basis.
Remote monitoring: A solar power plant constantly needs to be monitored to detect breakdowns and optimize its operation. The same function could be performed either on-site or remotely wherein we retrieve all the data either from the inverter or from communicating equipment (probes, meters etc.).
