How do Solar Pumps compare to mains electric pumps?

Solar technology is constantly developing, with photovoltaic panels becoming more efficient, alongside Lithium Ion batteries being more lightweight and much more powerful than their predecessors.  Pump manufacturers such as Oase Germany are constantly refining their pumping technology to make these more energy efficient.  The question is, are these solar powered alternatives now cost effective Vs mains electric pumps?  Let’s look at the pros and cons of both.

Mains Electric Pumps:  Pros.

• Cheaper to purchase
• Much wider range to suit many applications
• Low running costs on certain models
• Can be easily switched on/off
• Can be run continuously 24 hours per day, throughout the year.

Mains Electric Pumps:  Cons.

• May require a qualified electrician to install
• Can be tricky to lay a new power cable if a new installation
• Will consume energy during running, which is charged for by your energy provider

Solar Pumps:  Pros.

• Can be installed virtually anywhere that sunlight is present
• Pump can be sited in shady area with solar panel in sunny area
• Zero running costs
• Eco friendly, green solution
• Can be easily installed by a handyman or competent DIYer
• Safe, low voltage equipment

Solar Pumps:  Cons.

• Initial purchase costs higher than mains electric pumps
• Limitations on performance (not suitable for large projects)
• Limited equipment availability
• Operation is weather dependant, even with battery storage
• Can take many years to pay back Vs mains electric pumps

In conclusion, Solar Pumps are an excellent option if mains electric power cannot be obtained but, there are limitations.  If mains power is available, the equipment costs of mains Vs solar should be compared to justify the running cost-saving before purchasing.
