What is Solar Battery Storage?
Solar battery storage includes using batteries to store excess energy produced by solar panels for later use. This solution allows you to utilize solar energy even when the sun isn't shining. Common battery types include lithium-ion and lead-acid, each with distinct benefits.
When You Need Solar Battery Storage
Investing in solar battery storage is beneficial if you frequently experience power outages, want to minimize your electric bills, or aim for energy independence. However, if your energy consumption is low and your utility offers net metering, you might consider it less essential.
The Installation Process
The installation of a solar battery system typically involves several steps:
- Evaluation of your energy needs, which involves reviewing your past electricity bills.
- Choosing the right battery system based on capacity, type, and brand, with popular options like Tesla Powerwall and LG Chem.
- Obtaining necessary permits and approvals, often necessary by local building codes.
- Installation of the battery and integration with your solar setup, typically taking one day depending on system complexity.
