Education: Best Off Grid Solar System Guide


When we look at off-grid power systems, power is always one of the key features as you want to make sure you have enough oomph to charge your battery or run your appliances efficiently. When it comes to solar panels, you’ll generally find they range in power from between 30 watts and 300 watts

Solar panels with a capacity below 100 watts are generally smaller and more portable. Plus they’re cheaper if you’re on a tight budget. On the other end of the spectrum, 200 watt and more solar panels offer the most power meaning you can charge batteries and run bigger appliances. They will be bigger, more cumbersome, and expensive.


Along with the power rating, size is a key factor to analyze. You might want to start by thinking about where you are using your solar panels. Will you be mounting it on a shed roof, on a van, or elsewhere? Work out how much space you have available to ensure your solar system will fit. Adding to this, you might be thinking about adding more panels in the future so ensure there is space for your panels in the long run.

Static vs Portable

Deciding on a static mounted or a portable solar system will be dependent on how you are using your setup for off-grid power. If you are keen to mount your system to a roof or flat surface then it’s best to choose a solar panel you can mount easily on a flat surface. 

Alternatively, portable solar panels offer amazing versatility as you can carry them with you in a vehicle, set them up at campsites, or simply move them to meet direct sunlight. The trade-off is that you won’t be able to permanently mount them on your roof and won’t be built with such durable materials.

Included Accessories

To use a solar system you should ensure it comes with all the required parts including a solar panel, cables, charge controller, and mounting systems. Adding to this you will also have to purchase a suitable battery separately. 


Solar panels are a great way to save money in the long run. Simply put, the big benefit is that using the sun’s energy is completely free! While it requires an initial investment, it saves you money on electricity bills in the future. For this reason, it is crucial that your solar system lasts a long time, even decades. If you constantly have to spend money to repair or replace parts then you’ll lose the biggest benefit. Look for reputable manufacturers plus features like tempered glass, aluminum housing, weatherproofing, and anti-rust coating.


With off-grid power systems, safety is always a concern. Poorly made and faulty products can result in serious problems like fire! Adding to this, you want to make sure your battery and appliances are protected from faults like over-charging, reverse polarity, power surges, short circuits, and under-charging.
