Home Batteries… Tell me more!
Using batteries with solar is not a new concept. However, over the past few years, companies like Tesla have made home batteries more popular & more achievable.
But is it a worthwhile investment? That depends on your situation, your budget and what you are looking to achieve.
If you’re looking for a solar system that will pay for itself as quickly as possible, batteries may not be the best option for you!
However, home batteries may be for you if you’re already off grid or looking to install a solar system that minimises your reliance on the grid. Home batteries virtually eliminate your electricity bill. If you aren’t too concerned with ‘payback periods’ home batteries might be for you!
Common Home Battery Types
Flooded / Lead Acid
These batteries have been around for many years. They have great capacities and are great value for money on any off-grid solar power system. On the down side, they require a well ventilated installation, they’re very heavy and require regular maintenance.
Gel Cell Batteries
Gel batteries have the reliability of the lead acid batteries with some added benefits! They are faster to charge and discharge, they have a longer life, no maintenance and no harmful gas emissions during charging.
Lithium batteries have shot onto the market in recent years due to their light-weight construction. Many large companies are investing heavily in the research & development of the technology. Although they’re relatively new, their light weight and deep discharge without damage is a great feature!
