What is Solar Battery Storage?
Solar battery storage involves using batteries to store excess energy produced by solar panels for later use. This system allows you to make use of solar energy even when the sun isn't shining. Common battery types include lithium-ion and lead-acid, each with unique benefits.
When You Need Solar Battery Storage
Investing in solar battery storage makes sense if you frequently experience power outages, want to reduce your electric bills, or aim for energy independence. However, if your energy consumption is low and your utility offers net metering, you might find it unnecessary.
The Installation Process
The installation of a solar battery system typically includes several steps:
- Assessment of your energy needs, which includes 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 up to a week depending on system complexity.
Timeline for Installation
From initial assessment to final installation, the process can take anywhere from a couple of weeks, depending on factors like permitting and the contractor's schedule. Ensure you plan accordingly to avoid delays.
