Overview

On-grid solar power systems, also known as grid-tied systems, are photovoltaic (PV) systems that are connected to the electricity grid. These systems allow for the integration of solar energy with the existing power grid, enabling users to both consume and contribute electricity. This setup is particularly popular in residential, commercial, and industrial applications due to its efficiency and cost-effectiveness.

Key Components:

  1. Solar Panels: Capture sunlight and convert it into direct current (DC) electricity.

  2. Inverter: Converts the DC electricity generated by the solar panels into alternating current (AC) electricity, which is used by most household appliances and fed into the grid.

  3. Metering System: Measures the amount of electricity produced by the solar panels and the amount of electricity consumed from the grid. This often includes a bi-directional meter for net metering.

  4. Grid Connection: Links the solar system to the public electricity grid, allowing for the exchange of power.

STEP 01
img
Energy Generation

Solar panels produce DC electricity from sunlight.

STEP 02
img
Conversion and Storage

The hybrid inverter converts the DC electricity into AC electricity for immediate use and manages the charging of batteries. Excess energy not used immediately is stored in the batteries.

STEP 03
img
Energy Usage

During periods of low solar generation or high energy demand, stored energy from the batteries can be used. If battery power is depleted, electricity can be drawn from the grid.

STEP 04
img
Grid Interaction

Excess power generated can be fed back into the grid, often resulting in credits or compensation. During times when solar production is insufficient, electricity is drawn from the grid.

Advantages

img
Energy Independence

Provides backup power during outages and reduces reliance on the grid.

img
Cost Savings

Allows for greater self-consumption of solar energy, potentially reducing electricity bills and earning credits for excess power fed back to the grid.

img
Flexibility

Offers the benefits of both grid-connected and off-grid systems, including the ability to manage energy storage and usage effectively.

img
Increased Resilience

Battery storage ensures a continuous power supply during outages or periods of low solar production, enhancing overall energy security.

Considerations

Lorem ipsum amonsectetur. Nisla libero arcu adipiscing lectus ab biscuit Lorem ipsum amonsectetur. Nisla

01

Initial Costs

Hybrid systems can be more expensive upfront due to the cost of batteries and advanced inverter technology.

02

Battery Maintenance

Batteries require maintenance and eventual replacement, which adds to the long-term costs of the system.

03

Energy Management

Efficiently managing energy use and storage is crucial to maximize the benefits of a hybrid system and ensure that it meets the user's needs effectively.

04

Limited Power Supply

Hybrid systems involve more components and complexity compared to standard grid-connected or off-grid systems, which may require more specialized installation and maintenance.
