What is a Solar System?
As the demand and prices of electricity have kept on rising, the world looks at renewable energy sources for its power needs. In recent years, solar energy has become a popular renewable energy source because of its falling costs and improving efficiencies.
A solar system is a setup that generates electricity by utilizing the solar energy system. A typical solar system consists of solar panels (which absorb sunlight), inverter (which converts DC into AC), mounting structure (that hold the panels in place) and grid box and balance of systems (wires, nuts etc.). A solar system comes in various sizes like 1 kW, 3kW, 5kW, 10kW……1MegaW etc.
On-Grid (Grid-Tied) Solar System
A solar system which works with the grid is called on-grid or grid-tied solar system, there are three components in this system, such as
• Panels,
• Inverters,
• Installation Kit
The main purpose of installing an on-grid solar system is to save electricity bill.
Advantage
• Generate power for your Residential or Commercial Sector and sell access electricity to state government
• 4-5 years payback time and free electricity for next 20-21 years
Drawbacks
• Does not come with backup, the system does not work when there is a power cut or the Voltage is Low(Ac).
Are You Planning For Residential or Commercial Sector Solar System?
There are a number of steps to follow when you are planning to power your Residential or Commercial Sector with solar energy.
- Investigate Your Site's Energy Consumption
- Assess Your Solar Potential
- Assess Your Options for Using Solar
- Estimate Your Solar Electricity Needs
- Obtain Bids and Site Assessments from Solar Installers
- Understand Available Financing and Incentives
- Work with Your Installer and Utility
Which appliances run on the grid-tied solar system
The on-grid system works in sync with the grid, unlike inverters, there is no limitation in the grid-tied system, you can run everything of your Residential or Commercial Sector on the grid-tied solar system. For example, a 1 kW on-grid system can run 5 kW power.
Components of On-grid Solar System
A grid –tied solar system consists of the following components:
1. Solar Photovoltaic modules / Panels
2. DC-AC grid-tied solar inverter
3. Installation kit including of Mounting structures, ACDB, DCDB, A.C , D.C wire, Connectors, lighting arrestor, earthling cables.
What happens, when my power consumption is very low
The advantage of on-grid solar system is awesome, if you are not using electricity at your Residential or Commercial Sector, the power generated from solar system will be fed back to the grid. The state government will give you money for sending electricity to gird or You can use your excess generated electricity anytime.
