Inverter Home

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.

VEMC Solar Financial Solutions 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. 2. 3. 4. 5.

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

Sign a long term O & M Contract (optional)

Client pays for the EPC Cost

Carbon footprint reduction & tax saving VEMC undertakes the EPC activity In CAPEX model

Client will own the system

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 2 3 4

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

VEMC will Operate and Maintain the Plant for 25 years and its ownership will be with the Investor

Net Metering 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 modules Monocrystalline 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 modules Polycrystalline 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.

PRICE

Lower price

Higher price • production method: molten silicon is poured into a cast

production method: molten silicon is poured into a cast

EFFICIENCY

Lower efficiency • Average cell efficiency: 18%

Higher efficiency • Average cell efficiency: 19%

PERFORMANCE AT HIGH TEMPERATURES

Good • Blue cells absorb less heat • Efficiency Is not reduced as much at high temperatures

Reduced efficiency • Dark cells absorb heat • Causes efficiency reduction at warmer temperatures

APPEARANCE

Non uniform • The blue shade of the cells doesn't allow an all- black system

All black • Both cells and frame can be black. Allows a uniform look of the solar System

BEST SUITABLE FOR

Most cases • Lower price allows a faster return on investment • Panel's peak efficiency is usually not the primary consideration for solar system owners

Limited space • In cases of limited space peak efficiency can be Important

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, Inverter/ Converter
