Peak Shaving with Commercial Battery Storage – Demand is Rising

The demand for commercial battery storage for peak shaving is increasing. pv magazine has updated its market overview and notes that manufacturers’ prices have dropped by an average of five percent. While the market remains small in absolute terms, it’s growing rapidly

At Vela Solaris, we’re observing the same trend: more businesses are requesting energy system simulations that include storage. PV System Design, using the simulation software Polysun, you can demonstrate how integrating storage affects solar self-consumption, peak shaving (thereby reducing grid charges), or the integration of electric vehicles.

We’re pleased that Polysun is the only simulation software featured in pv magazine’s comprehensive market overview.

Pros and Cons of commercial battery storage technologies

1. Lithium-ion Battery Storage

Pros	High efficiency (up to 95%)Long life (thousands of charge cycles)High energy densityFast responste times
Cons	Higher upfront costs and sensitivity to temperatureSensivity to temperature

2. Lead–Acid Battery Storage

Pros	Lower costProven technology
Cons	Lower engergy densityshorter lifespanmore maintenance

3. Redox Flow Battery Storage

Pros	Very long life (tens of thousands of cycles)Robust cyclingScalablePower and capacity scale separately
Cons	Lower energy densityHigher initial costs

4. Second‑Life Battery Storage

Pros	Cost-effectiveRepurposing EV batteries
Cons	Lower performance and lifespan than new batteriesLimited availability

Using Simulation to Size Commercial Battery Storage

Our Polysun software helps identify the right size and configuration of commercial battery storage by analyzing your load profiles, feed-in tariffs, and grid charges. This allows you to find the most cost-effective solution.
