At OE Solar, we understand that battery energy systems are not suited for all customers. Battery systems are best suited for clients that do not have reliable power, need a back up for critical systems or have very high demand charges. Our experienced staff will perform energy studies to identify the best solution for your needs. We will even tell you “no” if a BESS system is just not right for your application. From energy security to savings money, batteries are finally developing the cost saving needs that companies care about.
For most businesses, energy consumption varies throughout the workday, At the macro level, utility providers vary their pricing throughout the day: during times of high electricity demand, “peak” utility rates kick; when energy demand goes down, “off-peak” pricing shifts.
With on-site battery storage, it’s possible to manage rising energy costs using a method known as “peak shaving.”
- Your on-site storage system charges whenever electricity rates are at their lowest (i.e., during off-peak hours or with your free solar energy)
- It then discharges during peak hours
This strategy allows you to save money without disrupting your normal operations.
Peak shaving with batteries isn’t something you have to manage actively. With the correct configuration, your smart energy storage system can regulate charging and discharging without any direct intervention from you.

Powerwall is an integrated battery system that stores solar energy for backup security, so during a utility power outage, your power stays on. Your system detects outages and automatically recharges with sunlight to keep your appliances running for days.
