Can you go off the grid with solar panels?


Welcome to our comprehensive guide on off-grid solar PV systems. In today's world, where environmental sustainability and energy independence are becoming increasingly important, off-grid solar PV systems are gaining traction as a viable solution for powering homes and businesses. If you're considering investing in solar and batteries to go off-grid, you've come to the right place. In this article, we'll delve into the technical aspects, advantages, and considerations of off-grid solar PV systems, providing you with the information you need to make an informed decision.

Technical Overview:

In short, yes, it's technically possible to go off-grid with solar PV and batteries. Such systems have been around for a long time and are particularly popular where grid connection is not possible for example on mobile homes, campervans, boats and so forth. Off-grid solar PV systems consist of solar panels, charge controllers, batteries, inverters, and other necessary components that work together to generate electricity and store it for use when the sun isn't shining. Solar panels capture sunlight and convert it into DC (direct current) electricity, an inverter converts this into AC (alternating current) electricity to power household appliances and equipment. This may also be fed into battery storage systems.

Advantages of Off-Grid Solar PV Systems:

Off-grid solar PV systems offer a range of advantages for those seeking energy independence and sustainability.

Energy Independence: 

By going off-grid with solar PV, you are no longer reliant on the conventional power grid, which is subject to price fluctuations, power outages, and other external factors. With an off-grid solar PV system, you have complete control over your own energy, reducing your reliance on fossil fuels and increasing your independence.


Off-grid solar PV systems are an environmentally friendly and sustainable way to generate electricity. Solar energy is a clean, renewable, and abundant source of power that does not produce harmful greenhouse gas emissions, contributing to a greener and more sustainable future.

Cost Savings: Although the upfront costs of installing an off-grid solar PV system may be higher compared to grid-tied systems, over the long term, you can realize significant cost savings. With no monthly electricity bills and the potential to sell excess electricity back to the grid, you can recoup your investment and potentially generate income from your solar PV system.

Remote Power Generation: Off-grid solar PV systems are particularly well-suited for remote areas where access to the conventional power grid may be limited or non-existent. With an off-grid solar PV system, you can enjoy reliable and sustainable electricity even in remote locations, making it an ideal solution for cabins, vacation homes, and other off-grid properties.

Considerations for Off-Grid Solar PV Systems:

While off-grid solar PV systems offer many advantages, there are also some considerations to keep in mind when considering this option.

System Sizing: Proper system sizing is crucial for the optimal performance of an off-grid solar PV system. It requires careful consideration of your energy needs, location, weather patterns, and other factors to determine the right size of solar panels, batteries, and inverters to meet your electricity demands.

Battery Storage: Batteries play a critical role in off-grid solar PV systems as they store excess electricity generated during peak sunlight hours for use during times when the sun isn't shining. Choosing the right type, size, and capacity of batteries is crucial to ensure reliable and efficient operation of your off-grid solar PV system. It must be ensured that enough battery capacity is specified, as enough energy must be stored to meet consumption outside of generating hours. 

Maintenance: Off-grid solar PV systems require more maintenance than their grid connected counterparts. This includes cleaning and inspecting solar panels, checking battery health, and monitoring system performance. It's important to factor in the cost and effort associated with maintenance when considering an off-grid solar PV system.

Weather Dependence: Off-grid solar PV systems are dependent on weather conditions, as solar panels require sunlight to generate electricity. During periods of low sunlight.
