What is a Grid-Connected Rooftop Solar PV System?
A grid-connected rooftop solar PV system transforms sunlight into electricity, feeding it into the electrical grid through solar panels and inverters. This setup allows you to harness solar power during the day and draw electricity from the grid when needed.
What Are the Main Components of a Grid-Connected Rooftop Solar PV System?
The key components include:
• Solar PV Modules/Solar Panels: Convert solar energy into DC electricity.
• Inverter: Converts DC electricity from panels into AC power synchronised with the grid.
• Module Mounting Structure: Supports panels in an optimal orientation for sunlight capture.
• Bi-Directional Meters: Measure electricity generated and consumed, facilitating net-metering.
• Balance of System: Includes cables, switchboards, junction boxes, and other components for system operation.
How Much Area is Required for a 1 kWp Rooftop Solar PV System?
You'll typically need around 10 square metres of shadow-free area for a 1 kWp system. The actual space required can vary based on panel efficiency and placement.
Why is a Shadow-Free Area Important for Solar Panels?
Shadows can significantly reduce energy output and shorten the lifespan of your panels. Ensuring uninterrupted sunlight maximises energy production.
Which Roof Types are Suitable for Rooftop Solar PV Systems?
Most roof types with adequate load-bearing capacity can support solar installations. Just make sure your roof gets enough sunlight throughout the day.
How Much Energy Can a 1 kWp Solar Power Plant Generate Daily?
On a clear, sunny day, a 1 kWp solar power plant can generate between 4 to 5.5 units of electricity, depending on local conditions.
Does Solar Energy Generation Vary Throughout the Year?
Yes, factors like temperature, solar irradiance, and weather conditions influence daily energy generation. So, output may fluctuate seasonally.
What Factors Influence Solar Power Generation?
Key factors include:
• Module Mounting Structure
• Equipment Quality
• Sunshine Hours
• Maintenance Practices
• Panel Tilt Angle and Orientation
Will Solar Panels Generate the Same Amount of Energy Over Their Lifespan?
No, solar panels degrade over time, which means energy production will gradually decrease over their 25-year lifespan due to exposure and environmental factors.
What Are the Advantages of Grid-Connected Rooftop Solar Systems?
The benefits include:
• Cost Savings on Electricity Bills
• Utilisation of Roof Space
• Quick Installation
• Reduced Environmental Impact
• Enhanced Grid Stability
How Much Does a Grid-Connected Rooftop Solar System Cost?
Costs vary based on system size, equipment quality, and location. Government subsidies and incentives can help offset initial investment costs.
What is Net-Metering and How Does it Work?
Net-metering allows you to use solar power for self-consumption and export excess electricity to the grid. It records energy flow in both directions, helping you save on electricity bills.
Can Rooftop Solar Systems Be Used Only for Self-Consumption?
Yes, behind-the-meter installations cater solely to self-consumption needs. However, these systems do not qualify for government subsidies in residential sectors.
