Solar Roof Top On Grid Systems
Solar Roof Top On Grid Systems
The Sun’s boundless renewable energy converted into the Clean and green sustainable form of energy for a brighter tomorrow is possible with the installation of Solar Roof Top on Grid System or Solar Photovoltaic (PV) System
What is this Solar Roof Top on Grid System?
It is a type of Solar Power Roof Top Installation which traps solar energy and converts it into the electrical energy using solar panels and stores it in a grid system. This system is highly versatile and installed on the roof tops of a Residential, Commercial, Institutional, Industrial, Governmental Buildings, Commercial Complexes, Parking Garages and Carports and even agricultural properties based upon the type of rooftops and their location and energy requirements.
Flat or Sloped Roofs with abundance of sunlight is ideal for this System installation.
What are the components of Solar Roof Top on Grid system?
| Component | Function | |
| Solar panels or Photovoltaic Modules | Traps Solar energy and converts into Direct current (DC) | Monocrystalline made up of single silicon crystal has greater efficiency up to 22% and Polycrystalline Solar panels made up of poly silicone crystals have efficiency ranging from 15-18%. |
| Solar inverters | Converts DC into AC (Alternate Current) and supplies to all the connected devices. | String Inverters handles many panels together. Micro inverters arranged for each panel. Power optimizers improves power output. |
| Net Bidirectional meter | Tracks importing and exporting of current from and to the Grid. | Reduces Electricity bills |
| Grid | Storage and Backup system for solar generated electricity. | |
| Mounting Structures | The Frame work which supports and secures solar panels on roof. |
Working process:
- Solar panels installed on the top of roof absorbs energy from the sun and converts that into Direct Current electricity.
- Inverter converts DC into AC and supply to most Household appliances.
- The Excess electricity Produced even after Household utility is sent to the Grids for Storage.
- Net Meter records the power stored in Grid and will be credited for this excess.
- During Nights and Cloudy days when solar panels are not able to generate electricity, Power from the grid will be drawn by the system for continuous supply.
Types of Solar Roof Top on Grid Systems
TYPE | DESCRIPTION |
Fixed tilt solar roof top system | In this Type the Solar panels are mounted on the roof at a fixed angle to get maximum sun exposure. Simple and Easy installation and economic. |
Adjustable tilt solar roof top system | Adjustable Mounting Framework i.e., Single axis and Dual axis trackers are used to Adjust Solar panels either in one axis or in both horizontal and vertical axis to trap maximum sun light. Costly due to the complex framework system.
|
Building integrated photovoltaics solar roof top system | Solar panels are included in the Roof top instead of traditional building roof top materials. Complex Constructional Strategies. |
Hybrid solar roof top systems | A battery Backup is integrated to the Solar roof top on grid System |
Grid tied solar roof top system with NET Metering | Conventional and most commonly used On-Grid System with Net metering. |
Single Phase and Three Phase Solar roof top system | Single Phase System Suitable for Smaller homes and buildings connected to a single-phase grid. Three phase system connected to a three-phase Grid for better capacity. |
Benefits Of Solar Roof Top On Grid Systems
- Cost Savings on Electricity Bills through Net Metering and reducing the amount of current drawn from Grid.
- Green House Gas emissions are reduced and hence termed Ecofriendly.
- Reduces reliability on Fossil fuels and acts as Clean and Green Renewable energy.
- No emissions so no Carbon Footprints and enhancing Sustainability.
- Battery Backup is Not necessary, As Grid acts as Backup Power.
- Minimal Technical Requirements and Charges due to Simple Installation
- Resilience to power price Fluctuations.
- Property Values jumps High due to Energy savings and Sustainable Features.
- If energy needs increase in future the System can be expanded by including Solar panels.
- Government Subsidies and rebates for installation reduces the investment costs.
- 20-25 Years of Warranty will be provided which highlights the durability of the cells.
