What Is a Solar Plus Storage Solution?
A solar plus storage system consists of a solar photovoltaic (PV) system joined with a Battery Energy Storage System (BESS) that captures extra solar energy for use in your business during peak demand. Rather than sending surplus electricity back to the grid at low feed-in rates or restricting solar generation due to grid constraints, the system stores excess energy and automatically supplies energy during peak demand, at night, and during blackouts.
An intelligent Energy Management System (EMS) is always monitoring the solar production, battery capacity, facility loads, and grid conditions of one such commercial and industrial facility for optimum charging and discharging capabilities of the battery. This helps alike to leverage the solar self-consumption, cut energy costs, boost energy resilience, and keep essential activities up and running.
Installing an entirely new solar system or integrating battery storage into an existing PV installation, a solar plus storage system is a scalable solution that is engineered for the future, improves energy independence, and increases your solar investment returns.
Why Is Your Solar Power Not Fully Utilized?
The PV system generates more electricity than the facility can use during certain daytime periods.
Excess solar electricity may be exported at a price much lower than the cost of purchasing electricity later.
Some projects are not permitted to export electricity to the grid, causing the inverter to limit PV output.
The facility still purchases grid electricity after solar generation has declined.
How Does a Solar Plus Storage System Work?
Solar plus storage system will automatically generate, store and consume electricity day in and day out. Your facility uses solar energy first, then the excess gets used to charge the BESS battery. When solar production is reduced or electricity demand increases, the battery discharges energy stored in the battery to reduce grid use.
An intelligent Energy Management System (EMS) automatically controls the charging and discharging of solar energy from the panel, taking into account various factors. The system typically operates in four stages.
Electricity is generated for facility loads through solar pv. The battery sits idle until there is excess solar energy.
Excess electric energy, generated by solar after meeting demand, gets stored in the battery instead of the grid.
When production from solar energy is low, stored energy from the battery can reduce peak electricity costs and operate the facility.
The battery will power the selected loads until the solar starts producing again or the utility power comes back on.

What are the benefits of a solar-plus-storage system?
A solar plus storage solution gives businesses more control over energy costs, its operational capacity, and lowers the price of energy. Organizations can save unused energy for peak-demand periods thus increasing their solar self-consumption. As a result, they reduce their dependence on the utility grid, electricity costs and enjoy reliable backup power during outages. Smart energy management ensures compliance with zero export regulations while leaving room for battery capacity upgrades as energy needs grow which helps businesses meet their sustainability and ESG goals in the long term.
Industries That Benefit from Solar Plus Storage Solutions
A solar plus storage solution works well for any business that uses a lot of electricity, often during peak tariff periods or with reliable backup power design requirements. HBOWA designs tailored commercial and industrial (C&I) energy storage solutions for many industries, with each C&I energy storage system designed around the facility’s expected energy use, operational requirements, and potential for expansion.

FAQ
Solar plus storage solutions are used by the commercial and industrial sectors:
- Manufacturing
- Warehouses and logistics
- Hotels and resorts
- Commercial buildings
- Agriculture
- Healthcare
- Telecommunications
- Data centers
- EV charging stations
Yes and sometimes no. In most instances, the engineers design the system in a way that it is possible to integrate battery storage into your existing grid-tied solar setup without having to replace your solar panel or PV inverter. Based on the equipment you already have an AC-coupled solution using a power conversion system (PCS) may be the easiest form. This enables companies to enhance solar self-consumption, lower power expenses, and include battery backup while optimizing their current solar investment, according to industry standards.
A hybrid inverter is a single device which is designed to manage solar generation as well as the battery, perfect for new solar-plus-storage systems. A Power Conversion System (PCS) is typically required if you are adding batteries to an existing solar system. As it doesn’t need any significant changes to the original installation, the battery can be operated with the existing PV inverter.
Affirmative. A system of solar plus storage can deliver backup power to the critical loads of a facility during utility outages but must be designed with backup capability. The back-up time for any system depends on the battery capacity, power consumption and load.
Affirmative. HBOWA’s Battery Energy Storage Systems can be modular and are expandable in the future. As your business develops or the demand for electricity increases, more battery cabinets can usually be added on with the original system.
