Introduction

On-grid solar systems, commonly known as grid-tied solar systems, are a cost-effective solution for converting sunlight into electricity. They offer significant environmental benefits by reducing dependency on fossil fuels and lowering electricity bills. This article provides an in-depth understanding of on-grid solar panels' functionality and evaluates their efficiency, focusing on specific parameters and solutions offered by Tongyao Company.

How On-Grid Solar Panels Work

On-grid solar panels function by converting sunlight directly into electricity through photovoltaic cells. These panels are connected to the local utility grid, which allows for the synchronization of electricity production and consumption.

During daylight, solar panels produce DC electricity, which is transformed into AC electricity via an inverter to match the local grid's frequency and voltage. This AC electricity is then fed into the home electrical system or sent back to the grid, earning credits or reducing consumption costs through a mechanism called net metering.

Components of On-Grid Solar Systems

Solar Panels

Composed of silicon cells, solar panels capture sunlight and convert it into DC electricity. The efficiency of these panels typically ranges between 15% to 20%, depending on the quality of materials and technology used.

Inverters

Inverters are crucial as they convert DC electricity into AC electricity. Modern inverters also manage real-time voltage and ensure the harmonization with the grid.

Grid Connection

The grid connection involves the integration of the solar system with the local utility grid. This ensures surplus energy can be fed into the grid while drawing energy back when solar production is insufficient.

Net Metering

Net metering policies allow owners to receive credits for excess energy produced. The meter records both input from the grid and output to the grid, balancing the homeowner's energy usage.

Parameters and Numerical Analysis

The performance of an on-grid solar system can be evaluated using several parameters:

• System Size: Typically measured in kilowatts (kW). A 5kW system can produce approximately 20 kilowatt-hours (kWh) per day, depending on the geographic location and weather conditions.
• Capacity Factor: Ranges from 15% to 25%. It indicates the ratio of actual output over a period compared to its potential maximum output.
• Annual Energy Yield: A 5kW system might generate between 5,475 kWh to 9,125 kWh annually, contingent on solar irradiance in the area.
• Payback Period: Typically between 5 to 8 years, influenced by local electricity rates and available incentives.
