What is Solar Battery Storage?
Solar battery storage entails using batteries to capture 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 unique benefits.
When You Need Solar Battery Storage
Investing in solar battery storage is beneficial if you frequently experience power outages, want to lower 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:
- 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 4-8 hours 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.
