Frequently Asked Questions
We use lithium iron phosphate (LFP) battery chemistry, which is one of the safest types of lithium ion battery. LFP batteries can also do more charge/discharge cycles than other solar batteries, without the environmental concerns relating to cobalt-based batteries.
On average a battery is similar in size to carry-on hand luggage which you'd take on holiday.
You’ll need somewhere to house the battery and system, they can be installed in most places such as in a garage, utility room or even under the stairs.
You don't need to have a battery for your solar PV panels to work. However, energy storage allows you to use more of the eco-friendly energy you generate in your home rather than exporting it back to the grid.
Without a battery back-up system, you will not be able to power your home with solar during an outage. While the grid shutting down is rare, batteries are a great way to keep you and your family energy secure during times of uncertainty.
Most batteries require addition of water every 6 to 12 months. There is no need to fill them more frequently than needed to submerge the plates. Fill them only to the level recommended by the manufacturer, generally about an inch below the top, otherwise they may overflow during finish-charging.
We are happy to include a solar battery back-up system to your custom quote. Please be sure to let one of our Sustainability Specialists know for it to be included in the quote or contact [email protected].
Three types of batteries are commonly used in solar storage: lead-acid, lithium-ion, and saltwater. Of these three options, lithium-ion batteries will last the longest.
The safest one in existence today is lithium iron phosphate battery technology, or LFP. These are highly stable and have no chance of overheating. They also run very cool which means they can be placed inside your home, if desired, and won't require extra ventilation or cooling.
between 5 to 25 years
On average, solar batteries last between 5 to 25 years.
Lithium-ion batteries are the most prevalent solar battery type and have a lifespan of up to 15 years. Some factors that impact a solar battery's longevity are battery type, installation, depth of discharge, cycle life, environment and maintenance.
Only some battery types are compatible with solar PV systems.
