Who Makes the Best Solar Batteries?
If you are investing in solar, adding battery storage is what turns a good system into a great one. A solar battery lets you store excess energy, reduce reliance on the grid, and protect yourself from rising energy prices.
At Green2Go, the goal is simple: help you choose a solar battery that actually fits your home, your usage, and your budget. This guide breaks down the types of batteries available, what features matter most, and which brands are leading the UK market right now.
What is a Solar Battery and Why Do You Need One?
A solar battery stores unused electricity generated by your solar panels so you can use it later. Instead of exporting excess energy back to the grid for a modest return, you keep more of your own power.
Key benefits:
- Lower electricity bills
- Greater energy independence
- Backup power during outages (with compatible systems)
- Better use of your solar generation
Types of Solar Batteries Explained
Understanding battery types helps you avoid overpaying or underperforming.
1. Lithium Ion Batteries (Most Popular)
These are the industry standard for residential systems.
2. Lithium Iron Phosphate (LiFePO4)
A safer, more durable variation of lithium batteries.
3. Lead Acid Batteries (Less common now)
Older technology mainly used for off grid setups.
Verdict: For most UK homes, lithium based batteries are the best choice.
