Rooftop Solar Power Installations are set to become the major energy source in the coming years. And rightly so – with an unending energy source in the form of the Sun and other major advantages, we stand to gain in the form of high returns on the investment made in these projects.
Servotech Power Systems Limited is Leading Led and Solar Product Manufacturer and Supplier, Servotech Solar Panel Rooftop Solar Power Systems stimulated by photovoltaic panels,which are associated with the utility grid. Grid-connected photovoltaic power frameworks consist of photovoltaic panels, MPPT, solar inverters, power conditioning units and grid connected equipment. Unlike stand-alone photovoltaic power systems, these systems seldom have batteries. At Servotech power systems limited, We committed to customer satisfaction and excellence. you are guaranteed to purchase this high quality product that will be functional in any state.
Rooftop solar power installations have assumed a lot of importance over the past few years, due to the increasing awareness about the need for renewable energy.
In India, the Government at the Center as well as the state levels knows the importance of solar power. Many schemes and activities have been started to promote solar power installation in India.
It is anticipated that by the year 2100 the temperature on the earth would have risen on an average by 1.8 degrees Celsius. In the worst possible case scenario, it could rise by 4 degree Celsius. High Carbon dioxide emissions cause immense damage to the environment.
In India, the Power sector in itself contributes around 50% of all emissions. A major part of the power generating activities relates to Non-renewable sources like Coal and Gas. With a population of 1.2 billion, we are the highest contributors of greenhouse gasses.
Regular power cuts, fluctuations, rising charges of non-conventional energy source make living tough here in India. However, the Sun is an enormous and unending source of renewable energy and India with a significant geographical presence on globe enjoys its riches.
Rooftop Solar Power installations are also known as Rooftop solar power systems or Rooftop Photovoltaic Power Systems. These are designed for roofs of commercial and residential establishments.
Types of rooftop solar power systems
There are mainly three types of Rooftop PV systems as listed below:
On-Grid System: It is the most commonly used system and is also called the Utility Interconnected system. This allows the user to use both solar energy and electricity provided through the grid. This system has the provision of Net-Metering, where surplus solar power produced by cells, is redirected to the grid. The benefit of this is received in the electricity bills at predetermined rates. On cloudy days when solar cells are not able to produce electricity, the power from the Grid is used.
Off-Grid System: In this system Generators substitute the grids in the case of shortage in production of electricity. Electric generators are added as a part of the whole system. These generators act as power backups and provide electricity when solar cells are not able to meet the requirement due to cloud cover or excess load.
Hybrid System: These systems are an upgrade of the On-Grid systems. Here the user gets the benefit of storage also and can enjoy environment-friendly energy all the time. An inverter is added into the system. Instead of sending excess electricity back to the Grid, it is first stored in this inverter. Once the storage capacity is met, left over power is then directed to Grid.
The solar photovoltaic system is a fairly simple one. Following are the major components:
Photovoltaic cells are the primary and fundamental building part of a solar energy system. These cells are made of semiconductor material, like silicon. A Glass covers these silicon cells on top, allowing sunlight to pass through them on silicon cells.
At night or at the time of a cloud cover solar cells reduce or stop generating electricity. At this stage, we use electricity from the standard grid and are billed in utility bills accordingly. When there is excess surplus power, these meters redirect them to the grid, resulting in the backward spinning of the meter.
The reverse spinning of meter helps in reducing energy bills. In Utility bills, net consumption is considered. That is why these meters are also called ‘Net Energy Meters’ and process of charging at net usage is called ‘Net Metering.’
In 2015 through the Intended National Determined Contribution (INDC) as many as 162 countries including India submitted the steps they would be initiating at various levels to limit global warming. As part of these initiatives, India committed to generating 40% of its electricity through renewable sources of energy by the end of 2030.
