Energy Storage
Commercial Battery Storage — End Load-Shedding at Your Premises
Every hour of load-shedding your business experiences has a measurable rand cost — in lost production, equipment damage, spoiled inventory, and staff downtime.
The Real Cost of Load-Shedding
For a manufacturing business with 50 employees, Stage 4 load-shedding (4–6 hours per day) can cost R15,000–R50,000 per day in lost productivity.
Panyanru Solar installs commercial Battery Energy Storage Systems (BESS) that eliminate load-shedding's impact on your business entirely. A correctly sized BESS provides 4–12 hours of clean, silent backup power at the push of a button — automatically switching your critical loads to battery power the moment the grid fails.
How Much Is Load-Shedding Costing Your Business?
| Business Type | 50 Employees Stage 4 Impact/Day | Monthly Cost at Stage 4 (5 days/wk) |
|---|---|---|
| Manufacturing / Production | R25,000–R50,000 — All production stops; shift workers idle | R500,000–R1,000,000/month |
| Cold Chain / Refrigeration | R8,000–R20,000 — Spoilage risk; compressors restart surge | R160,000–R400,000/month |
| Retail / Hospitality | R5,000–R15,000 — Point-of-sale down; kitchen inactive | R100,000–R300,000/month |
| Office / Professional Services | R3,000–R8,000 — Servers down; video calls drop; UPS systems overworked | R60,000–R160,000/month |
BESS + Solar vs BESS Standalone — Which Is Right for You?
| Feature | Solar + BESS | BESS Standalone |
|---|---|---|
| How it works | Solar panels charge the batteries during the day; batteries power critical loads during load-shedding and at night | Batteries charge from Eskom grid during cheap off-peak hours; discharge during load-shedding and peak tariff periods |
| Best for | Properties with good roof or land availability; businesses wanting to reduce electricity bills AND eliminate load-shedding | Properties without suitable roof space; businesses that primarily want load-shedding protection without solar installation |
| Capital cost | Higher (solar + BESS) | Lower (BESS only) |
| Electricity bill savings | Significant (solar offsets grid purchases) | Moderate (time-of-use arbitrage only) |
| Load-shedding protection | Full (during daylight); partial overnight depending on BESS size | Full (limited by battery capacity and charge level at time of outage) |
| Panyanru Solar recommendation | ✓ Preferred solution for most C&I applications | Recommended where roof/land constraints prevent solar installation |
