Off Grid Solar Power System

What is an Off-Grid Solar System?

An off-grid solar system is a stand-alone power system that enables you to generate and store your own electricity without being connected to the main electricity grid. These systems typically include solar panels, batteries, inverters, and other components to convert sunlight into usable electricity.

Understanding Off-Grid Solar Systems and Why Target Solar Stands Out

When we talk about off-grid solar, we’re referring to a self-sufficient electrical setup that operates independently of the traditional power grid. So, you may wonder, how does one meet all their electrical needs without relying on mainstream electrical supply? The answer lies in the power of off-grid or stand-alone solar systems.

These systems are designed to empower you with electrical independence, particularly in remote regions where conventional electricity is either unreliable or prohibitively expensive. In essence, an off-grid solar system comprises solar panels—usually mounted on the roof or ground—a charge controller, a battery bank for energy storage, a backup diesel generator integrated with the solar setup, and an inverter that synchronizes all these components. Battery storage is a crucial part of this configuration, often making up to 40% of the system’s total lifetime cost.

Why Choose Target Solar’s Off-Grid Systems?

What sets Target Solar apart from the competition is the ease of maintenance and technological advancement in our off-grid solutions. Our state-of-the-art systems are fully automated, providing you with the convenience of monitoring and control through a Wi-Fi-enabled device.

But that’s not all. The quality of electricity you get from a Target Solar off-grid system is generally superior to what you’d receive from a traditional power grid. Why? Because you’re using energy that you’ve generated yourself, free from any third-party interruptions or fluctuations. This cleaner, more reliable power supply not only gives you electrical independence but can also extend the lifespan of your electrical appliances.

By choosing Target Solar, you’re not just opting for an off-grid system; you’re investing in a higher quality, more reliable, and technologically advanced solution for your electrical needs.

    Self-sufficiency of Off-grid solar system

    Technically the recommended battery bank autonomy of an off-grid solar system is about 1.5 – 2 days. However, without a generator an off-grid solar system can operate in independently for 2-3 days. This means that during bad weather condition when there is no sun or little exposure, your off-grid solar system can provide enough back up energy for up to 3 days to run all your electrical appliances. The size of the battery bank can be calculated by multiplying the daily kWh usage with the number of days you would like to have autonomy. For instance, for a daily usage of 12kWh, you would need a battery bank with 24kWh usable storage.

    Off-Grid Solar Power Stations vs. Home Systems: What’s the Difference?

    Off-grid solar solutions come in various sizes and complexities, primarily falling into two categories: commercial off-grid solar power stations and home systems. While both aim to provide a reliable source of renewable energy, their scale, components, applications, and costs differ significantly. Here’s a detailed breakdown to help you understand these two distinct categories.

    Scale and Capacity:

    • Large-Scale: Designed to power multiple homes, businesses, or even entire communities.
    • High Capacity: Ranging from tens of kilowatts to megawatts, these stations have substantial energy output capabilities.


    • Multiple Arrays of Solar Panels: Often set up over acres of land.
    • Industrial Batteries: Larger and more resilient than residential batteries, designed for extended use.
    • Advanced Inverters: To handle the large-scale conversion of electricity.
    • Sophisticated Charge Controllers: Often more than one, capable of managing high energy flows.

    Cost and Investment:

    • High Initial Cost: Because of the scale, the initial investment is generally high.
    • Returns on Investment: More suited for long-term energy needs and often more cost-effective in the long run.


    • Utility Scale: Can be used for rural electrification, powering industrial setups, or supplementing a local grid.
    • Multiple Users: Designed to supply energy to various consumers simultaneously.


    • Specialized Team: Requires a team of experts for regular monitoring and maintenance.
    • Automated Monitoring Systems: Advanced systems to monitor the health and efficiency of the solar station.

    Scale and Capacity:

    • Small-Scale: Specifically designed for individual homes or small businesses.
    • Limited Capacity: Usually ranging from 3 to 10 kilowatts depending on the home’s energy needs.


    • Single Array of Solar Panels: Typically installed on rooftops or in yards.
    • Residential Batteries: Smaller in size and designed for less intense usage.
    • Basic Inverter: Sufficient for converting the home’s electricity needs.
    • Single Charge Controller: Usually one is enough for the whole system.

    Cost and Investment:

    • Lower Initial Cost: Smaller scale means less initial financial outlay.
    • Shorter ROI Period: The investment usually pays off more quickly due to smaller scale.


    • Single-User: Primarily used for powering a single home or small business.
    • Limited to Household Needs: Designed with the energy consumption of a single property in mind.


    • DIY or Professional: Often manageable by the homeowner, though professional services are available.
    • Simpler Monitoring: Usually, a straightforward monitoring system or even a mobile app can suffice.

    Off Grid Solar Battery Connection: Understanding AC and DC Coupled Off-Grid Systems

    Navigating the world of off-grid solar systems can be confusing, especially when it comes to AC and DC coupled configurations. Let’s break down these two distinct setups to help you understand what each offers.

    DC-Coupled System

    In a DC-coupled arrangement, energy harvested by the solar panels is directed through an MPPT (Maximum Power Point Tracking) charge controller and stored directly in a battery bank. During power outages, an AC inverter connected to the battery bank converts the stored DC power into usable AC electricity. In simple terms, the flow of electricity goes from the solar panels straight to the battery, only converting to AC when you need to use it.

    AC-Coupled System

    In contrast, an AC-coupled setup uses an AC inverter to immediately convert the DC power generated by the solar panels into AC electricity. This AC power is then distributed to meet the immediate needs of your home or facility, bypassing the battery storage. For battery storage, a separate bi-directional charging inverter is used. This inverter not only charges the battery with excess energy but also draws power from it when needed, effectively managing your entire off-grid solar system.

    Automation and Generators

    Regardless of whether you choose an AC or DC coupled system, automation can be integrated based on your generator requirements. This allows for more streamlined and efficient energy management.

    For a deeper dive into these configurations, book a free consultation.

    By understanding these two configurations, you can make a more informed choice about which off-grid system best suits your needs.
