ABOUT US

Why Solar Photovoltaic technology?Solar energy is energy supplied by nature –

it is thus free and abundant! Using PV

technology, the Solar PV modules provide

clean and green energy. Electricity

generation with Solar PV modules, does

not produce harmful greenhouse gas

emissions thus Solar PV is environmental

friendly.

VEMC works to provide end to end EPC service to valued clients.

VEMC brings decades of experience working with various industries in Oil, Pharmaceuticals, Building & Construction, Water Supply & now solar solutions. When approached with any projects, the company undertakes a 6 step process to ensure flawless execution. After an initial site survey, feasibility study, procurement of required equipment and installation, the company also undertakes commissioning of projects to ensure that the set up operates efficiently.

Grid-tied system

This system is synchronized with the utility supply mains at the distribution box. It uses an inverter which has special provisions to match the grid supply using sensors and reduce the total power consumption from grid.

Off-Grid system

This system is independent of the power grid. It has a battery bank to store excess electrical

energy generated during day time and utilize this energy during night time when solar energy is

not available. This is useful for locations situated far from electricity grid lines like remote tribal

villages, Defense posts, forest checkpoints etc.

Hybrid System

This is a combination of both the on-grid and off-grid system, it is a grid connected solar

photovoltaic system with a provision for battery backup to store energy. This is useful for

electricity consumers having very high tariff rate, like commercial parks and malls.

Optimized grid tied system

This is one of a kind solar system focusing mainly on the module optimization by using individual

module optimizers and special solar inverters. It is based on global ground breaking technology

for improving solar plant performance.

CAPEX Model

In this finance model, the client or any entity approaches VEMC for installation of a Solar PV system

in the premises of the client. Once the plant is commissioned, its ownership transfers to the client and

the VEMC’s scope ends.

The advantages of this model include: 1. The client has complete ownership over the plant and its operation. 2. Client can reduce his electricity bills by sizable margins depending on the capacity of Solar PV plant. 3. Client can avail CFA (Central Finance assistance) Subsidies and tax benefits from Government bodies. 4. Client can complete his CSR and Renewable energy use and purchase obligations. 5. Client becomes partially immune to increasing Utility electricity prices.

OPEX Model

In this financial model, the complete project cost is financed by the investor and executed by

VEMC and the power generated is sold to client. The Client enters into a long-term contract

(typically referred to as the PPA) to purchase 100% of the Electricity generated by the system.

The advantages of this model include:

1 Clients consumes Electricity at a discounted price 2 No investment from Client side. 3 VEMC will manage the permits, construction, maintenance and operations of the system. 4 Client can meet his Corporate Social Responsibility (CSR) at no additional cost.

Net Metering

Net metering is a billing mechanism that credits solar energy system owners for the electricity they

add to the grid. It allows Utility power consumers who generate some or all of their own electricity

to use at anytime, instead of when it is generated allowing the consumers to give extra solar power

in to the grid when their demands for power are met and recover the grid injected energy whenever

their generation from solar system is low. This system enables the consumer to achieve substantial

reduction in the electricity bill (The bill could be as low as zero in some cases).

Components

PV Modules

VEMC offers Monocrystalline PV modules & Polycrystalline PV modules.

Monocrystalline PV modulesMonocrystalline solar panels use single-crystal silicon. Because the cell is composed of a single crystal, the electrons that generate a flow of electricity have more room to move. As a result, monocrystalline panels are more efficient than their polycrystalline counterparts.

Polycrystalline PV modulesPolycrystalline solar panels are also made from silicon. However, instead of using a single crystal of silicon, manufacturers melt many fragments of silicon together to form the wafers for the panel.. Because there are many crystals in each cell, there is to less freedom for the electrons to move. As a result, polycrystalline solar panels have lower efficiency ratings than monocrystalline panels.

On an average the Polycrystalline Modules give slightly better ROI when compared to Monocrystalline PV modules due to their comparatively lower costs and similar electricity generation.


Inverters

Solar Power inverter is the heart of any Solar Power plant. Solar power inverters have special functions adapted for use with photovoltaic arrays other than DC to AC power conversion, like maximum power point tracking, System monitoring and anti-islanding protection.

VEMC provides below Solar inverters types:

Stand-alone inverters

Stand alone inverters are used in isolated systems where the inverter draws its DC energy from batteries charged by photovoltaic arrays.

Grid-tie inverters

Grid tie inverters are designed to operate in Synchronism with the Utility grid. They are designed to shut down automatically upon loss of utility supply, for safety reasons. Solar grid tie inverters are used for net metering purposes.

Hybrid inverters

Hybrid inverters are designed to draw energy from a battery, manage the battery charge via an onboard charger, and export excess energy to the utility grid. This is a combination of both standalone and Grid-tie inverters and can be used for net metering purposes. The inverter comparison is given as follows,

DC/DC Converters(Power Optimizer)

Module Power Range

up to 98.8% • Ease-of-replacement concerns• Output is DC with optimized current• Still a DC / AC inverter is needed• 2 GWp installed in 2016

Cables

Solar cable is the interconnection cable used in photovoltaic power generation. Solar cables are designed to be UV resistant and weather resistant. They can be used within a large temperature range and are generally laid outside.


Module mounting system

Solar mounting structures are the backbone of any Solar PV plant installation. They provide the

necessary support to the Solar Modules against environmental attacks like rains, cyclones and

dust storms. Mounting can be done on a variety of surfaces like RCC roofs, Galvenium sheets,

Asbestos sheets and ground.

Monitoring system

The solar PV systems provided by VEMC have an integral Monitoring System. The system

enables diagnostic and monitoring of all components. The monitoring can be done remotely on

Smartphone’s or any other computer systems.
