Home Batteries… Tell me more!
Using batteries coupled with solar is not a new concept… But over the past few years thanks to companies like Tesla, home batteries are becoming more and more popular, but is it a worthwhile investment? Well 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 quick as possible – batteries may not be the best option for you!
If you’re already off grid, or are looking to install a solar system that minimises your reliance on the grid, virtually eliminates your electricity bill and you aren’t too concerned with ‘payback periods’ and would rather peace of mind and energy independence – home batteries might be for you.
Common Home Battery Types
Flooded / Lead Acid
Lead acid batteries have been around for many years – and boast great capacities and good value for money on any off-grid solar power system. They do, however require a well ventilated installation, are extremely heavy and require regular maintenance to ensure long life.
Gel Cell Batteries
Gel batteries have the proven track record and reliability found with the standard lead-acid batteries, but Gel Cell batteries have some added benefits like faster charging and discharging, longer life, no maintenance and no harmful gas emission during charging!
Lithium batteries have shot onto the market in recent years due to their light-weight (compared to Lead acid and GEL) construction. Many large companies are investing heavily into the research and development of the technology. Although relatively new, their light weight and deep discharge without damage is a great feature!
