What Is An Off-Grid Solar System

Solar panels off-the-grid systems are large enough to meet the electricity needs of homes or businesses. These systems combine robust off-the-grid solar panels and a portable power station to produce and store electricity for home needs.

An off-grid solar system pulls off the sun's energy using solar panels, which are then routed to a battery. All the generated energy is stored in the power station that contains an in-built inverter. You can connect the power station to any home or outdoor appliances and start recharging it.

Main Components Of An Off-Grid Solar System

Most off-the-grid solar panel systems in the market consist of solar panels, an inverter, a battery, and a solar charge controller. Let's explain them briefly.

Solar Panels

The most critical component of an off-the-grid solar system is the solar panel. The role of these photovoltaic cells is to convert the light rays that fall on them into electricity. Jackery SolarSaga Solar Panels uses high-efficiency monocrystalline solar cells, a durable ETFE frame, and a lightweight aluminum design.

Jackery solar panels have a high solar conversion efficiency of 24.3%, ensuring maximum sun rays are trapped and converted into electricity. One of the best parts about Jackery SolarSaga Solar Panels is that they are foldable and portable.

Inverter

Most modern power stations consist of an in-built inverter to convert the direct current (DC) generated by panels into usable alternating current (AC). A solar inverter is a critical component in an off-the-grid solar panel system to ensure all appliances are charged using a safe and reliable current.

Charge Controller

The role of the charge controller is to improve the battery's efficiency and safety while charging. Jackery Explorer Portable Power Stations consist of in-built MPPT solar charge controllers to protect the battery from overcharging and maintain reliable power flow.

Battery

The excess energy generated by panels during the day is stored in the battery or power station for later use. The power stations or batteries supply electricity to appliances during power outages, on cloudy days, or at night.

Off-Grid Vs. Grid-Tie Solar System

Off-grid and grid-tied solar systems are two popular options to power homes without solely relying on the electricity grid.

Off-the-grid solar power systems are not connected to the utility grid and require batteries to store excess energy.

Alternatively, grid-tie systems are connected to the grid, so they can sell extra power back to the utility company.

Below are the different types of off-the-grid solar systems.

Solar-Only System

As the name defines, solar-only systems rely exclusively on solar panels. These solar panels are sometimes connected to batteries to store the excess amount of electricity and power appliances when sunlight is unavailable.

Jackery SolarSaga Solar Panels are highly-efficient solar solutions that convert maximum sunlight into electricity. They are foldable and portable, making them an excellent solution for home and outdoor power needs.

Generator Backup

This off-grid solar system consists of solar panels with a backup generator. The solar system generates electricity during the day and stores the extra energy in the generator.

Jackery Solar Generators combine solar panels and backup batteries. They work in tandem to absorb, collect, and convert sunlight and charge home appliances using solar energy.

Hybrid Solar System

The hybrid solar system combines three power sources: solar panels, current grid connection, and batteries. Solar power panels produce electricity during the day, while homeowners can harness the power from the main grid at night.

Jackery Solar Generator 3000 Pro is designed with a sizable 3024Wh battery capacity and SolarSaga 200W Solar Panels. You can charge nearly 99% of home or outdoor appliances, ensuring you never run out of power.

Comparison Between Off-Grid & Grid-Tie Solar Systems

There is no simple answer to which solar panel system is best. The ideal type of solar system for you will depend on your needs and circumstances. If you live in a remote location or want to be completely independent of the grid, an off-grid system may be the best option. On the contrary, a grid-tie system may be a better choice if you live in an area with a reliable grid.

Off-Grid Systems

These systems utilize solar batteries to store extra energy generated by solar panels.

Pros: They are a reliable solution when you live in a remote area without affordable and reliable access to the grid.

Cons: It has a higher upfront cost, as you'll need to purchase solar panels and a compatible battery.

Grid-Tied Solar Systems

Also known as on-grid systems, they use the electricity produced by panels during the day and tap into the grid at night.

Pros: You can save money on high electric bills and receive compensation for the excess energy credited to the utility grid.

Cons: This solar system does not offer access to electricity during the blackout.

Is going off-the-grid right for you?

Off-the-grid solar panel systems may not be suitable for everyone, but they are a worthy investment if you fall into any of the aspects mentioned below.

• You want to enjoy a mobile lifestyle in your RV or camper van.
• You want to reduce your carbon footprint by choosing a green solution.
• You live in an area prone to blackouts, brownouts, or long-term power outages.
• You want to reduce your dependency on the electricity grid.

How to Choose Off The Grid Solar System

There is a growing interest among homeowners in using off-the-grid solar panel systems. The reason is that living off-grid reduces your carbon footprint and your dependency on the electrical grid.

However, you'll need to choose a high-quality off-grid solar kit that is powerful and easy to use. Below we reveal a few factors you need to consider while selecting the best off-the-grid solar panels system.

Energy Needs: Understanding how much power your home appliances consume can help you finalize the best off-the-grid solar system. For instance, if you want to power your entire home, consider investing in a large power kit like an expandable Jackery Solar Generator 2000 Plus.

Budget: Off-grid solar panel systems can vary in price depending on their type, efficiency, and size. If you are tight on budget, you can choose a small power station and a few solar panels for solar charging.

Quality: When investing in an off-grid system, you'll need to prioritize the quality of solar panels and power stations. Always look for batteries and solar panels that are durable, efficient, and reliable.  

How Many Solar Panels Do I Need to Be Off The Grid

One common question homeowners ask before investing in a solar solution is, "How many solar panels do I need to be off the grid."

If you want to determine the number of solar panels required, you'll need to calculate your power usage, the amount of sunlight you receive, system efficiency, etc.

Power Usage: The first step is to determine how much energy you require. You can check your most recent bill to get an estimation of kWh consumption. Alternatively, you can calculate the amount of watts your home appliances use and add them to get the total power usage.

Sunlight Received: The next step is to calculate the hours you receive peak sunlight. If you live in an area with a very high peak sunlight rate, a small power station of around 2000 or 3000 watts would suffice.

Solar System Efficiency: No solar system works with 100% efficiency. Therefore, it's crucial to consider the system losses and add 15-20% of power to your daily energy needs.

Let's take an example to understand better:

Suppose you want to power your home appliances that consume around 2000 watts daily, and your location receives 5 hours of sunlight.

If you are considering a solar panel of 300 watts, you'll need to purchase around 10 solar panels. However, that's not the case if you choose Jackery Solar Generators. These solar systems combine a powerful battery with solar panels to supply electricity to home appliances.

While Jackery Solar Generator 3000 Pro can efficiently charge 99% of home appliances, Jackery Solar Generator 5000 Plus supports days of home backup. Depending on your power needs, you can invest in the right size power station or solar generator.
