What is Solar-Plus-Storage?

In an era of growing environmental consciousness and increasing energy costs, achieving energy independence at home has become a significant aspiration for homeowners. We have mentioned four ways of common ESS method in the previous articles.

In this blog article, we will explore one of the ESS of residential energy storage systems, the solar-plus-storage.

What is solar-plus-storage?

Solar plus storage combines solar panels and battery storage in one connected system for optimal energy management. In solar-plus-storage system, PV panels capture solar energy and convert to electricity. The battery stores the extra solar energy for later use. When the power of the photovoltaic system is insufficient, the energy storage system will convert the stored electrical energy into the required AC power supply network for use .


How Do Solar-Plus-Storage System Work in one day?

In the morning

Normally, the light intensity is weak in the morning. If the energy produced by solar panels is monitored that too low to power the home. The energy storage system will automatically converts the DC stored into AC power for use.

At afternoon

The solar energy captured by solar panel is at its peak at noon. And energy consumption is very low, so most of the energy generated is stored in batteries.

At night

The highest daily energy consumption is at night when the solar panels generate little or no energy, and the energy storage system will use the energy generated during the day to meet the energy demand.

Uses of Solar Plus Storage

Solar batteries let you make the most of your own renewable resources. During the evening hours and on cloudy days, a solar plus storage system lets you power your home with clean solar energy generated onsite. As part of smart connected system, they also provide backup power during power outages.

When might you use solar + storage?

At night and on cloudy days – When your solar panels aren’t able to generate energy from the sun, your system can draw from your battery rather than from the grid.

During peak demand hours – When electricity is more expensive and the grid is stretched, you can use the stored energy from your battery rather than racking up kWh at the top rates.

During power outages – If electricity is cut due to extreme weather or pressure on the grid, solar battery systems wired for backup power make use of your stored solar energy for free.

Why Is Storing Solar Energy Important?

Storing solar energy gives you more control of your resources and your electric bills. It puts your own needs first and uses expensive electricity from the grid as a last resort. With solar power storage systems, the energy generated by your PV panels makes a bee-line to your battery – and only goes back to the grid when your battery is fully charged. Likewise, the only time you’ll need to draw electricity from the grid is when your battery is on empty.

PV panels regularly produce more electricity than can be used. Unless the PVs are paired with solar batteries, this excess is delivered back to the grid – it’s “use it or lose it.” The same goes for backup storage. If your battery isn’t wired for this, that excess solar energy is sent back to the grid. Oftentimes, the more advanced solar plus storage systems provide cost savings in the long run.
