Solar 101: Batteries

Does my solar energy system need batteries?

It is not mandatory. Most people are using the on-grid solar system tied with the utility grid. But, if you want to install an off-grid solar system that is not connected to the grid, you need batteries.

How does energy storage work with grid-tie systems?

In a grid-tied solar system, the energy provider pays for the extra energy that the grid receives from the homeowner. It allows you to save electricity costs. When batteries are used for storage, the system is called battery-to-grid.

Which battery chemistry is best for solar? (FLA / SLA / Li)

A solar system should have the best quality solar appliances, and batteries are very important. Lithium-ion (Li) is the best battery chemistry for a solar system when it comes to storage. It doesn’t require any maintenance and venting.

Solar 101: Racking For Solar System

Ground mount or roof mount?

There are two types of mounting options for solar panels. The roof mount system holds the solar panels on the roof with a rack and steel structure. Solar panels are installed on the ground by establishing a foundation on the ground level for the ground mount system.

What are pole mounts? Are they worth it?

To help you understand a solar 101 conversation more easily, the pole mount system allows you to install the solar panels on a pole mounted on the ground. It is not so different from the ground mounting option because the system requires pole installation on the land.

What are trackers? Are they worth it?

A solar tracker is a device that allows you to track the sun’s path in the sky. It works just like a sunflower to optimize the sunlight for producing more solar power. The biggest benefit of this tracker is that you can boost your electricity production.
