SOLAR POWER PLANT

ONGRID POWER SYSTEMS

ONGRID POWER SYSTEMS

An on-grid photovoltaic power system, or grid-connected PV system is an electricity generating solar PV system that is connected to the utility grid. A grid-connected PV system consist of solar panels, a power conditioning unit and grid connection equipment. They range from small residential and commercial rooftop systems to large utility-scale solar power stations. Unlike stand-alone power systems, a grid-connected system rarely includes an integrated battery solution, as they are still very expensive. When conditions are right, the grid-connected PV system supplies the excess power, beyond consumption by the connected load, to the utility grid.

> Power bill is reduced by export of surplus electricity.

> Cost of plant is less as it doesn’t require battery.

> Utmost utilisation of generated power.

> If adequate power is not generated, it will draw from grid.

> Less maintenance as only cleaning of panel once a week.

> Energy meter to be replaced by net meter for net consumption of export and import.

> Solar power likely to go waste during load shedding.

(Hybrid System can be used to avoid this condition).

OFFGRID POWER SYSTEMS

OFFGRID POWER SYSTEMS

An off-grid can be stand-alone power system or mini-grids typically to provide a smaller community with electricity. Off-grid electrification is an approach to access electricity used in countries and areas with little access to electricity, due to scattered or distant population. It can be any kind of electricity generation. The term off-the-grid (OTG) can refer to living in a self-sufficientmanner without reliance on one or more public utilities.

> Power will be available for limited period even in the absence of grid supply.

> Back up depends on size of the battery.

> More space and attention required.

> Battery maintenance is a cumbersome process.

> Replacement of batteries once in 3yrs.

> Generation loss, due to charging and discharging of batteries.

> Cost of the system will be more comparatively.

HYBRID POWER SYSTEMS

HYBRID POWER SYSTEMS

Hybrid solar systems combines the best from grid-tied and off-grid solar systems. These systems can either be described as off-grid solar with utility backup power, or grid-tied solar with extra battery storage. Hybrid solar systems utilize batter-based grid-tie inverters. These devices combine can draw electrical power to and from battery banks, as well as synchronize with the utility grid.

>This system take advantage of changes in the utility electricity rates throughout the day

>This system is quite costlier than on-grid and less expensive than off-grid.

 

BENEFITS OF SOLAR ROOFTOP POWER PLANT:

The Solar power policy of Government has offered several benefits to independent solar power producers (IPP) and your requirement qualifies for such concessions.

  1. Income Tax benefit: the investor is entitled for 80% DEPRECIATIONon the amount invested on the solar project.
  2. SUBSIDY: Available as per Government norms.
  3. Free Electricity: The electricity produced by the solar power plants are FREE, UNINTERRUPTED, THROUGHOUT THE DAY,
  4. Savings: (i) There will be a huge savings by way of cost reduction in our electricity bills.                                                  (ii) Solar power plants can be installed easily near the load centers, thus we ca save lot of transmission hardware such as transmission towers, insulators, conductors etc., besides huge saving in transmission losses of power.
  5. Sale of Electricity: The excess power generated or unused power can be sold to the Electricity Board on a PPA (Power Purchase Agreement) through Net metering system.
  6. Pollution Free: Solar energy is non-polluting, clean, reliable and renewable source of electricity. It does not pollute the air by releasing harmful gases like carbon dioxide, nitrogen oxide and sulpher oxide. Solar energy does not require any fuel and thus avoid the problems of transportation of fuel or the storage of radioactive waste.
  7. Solar power plants can be installed easily near the load centers, thus we can save lot of transmission hardware such as transmission towers, insulators, conductors etc., besides huge savings in transmission losses of power.
  8. The technological advancements in solar energy systems have made them extremely cost effective.
  9. Most systems do not require any maintenance during their lifespan, which means NILrunning cost.
  10. Our systems have a life span of 30 to 40 years.
  11. Our systems carry a full warranty for 25 years or more.
  12. Unlike traditional monstrous panel systems, many modern systems are sleeker such as Uni-Solar rolls that lay directly on the roof like regular roofing materials.
  13. In most states, solar energy is fed back to the utilities to eliminate the need for a storage system as well as eliminating or dramatically reducing your electric bills.
  14. Solar energy systems are now designed for particular needs. For instance, you can convert your outdoor lighting to solar. The solar cells are directly on the lights and can’t be seen by anyone. At the same time, you eliminate all costs associated with running your outdoor lighting.
