Commercial & Industrial Solar + Battery
Cut your energy bill by 40-60% with PV + BESS
Solar generates by day, battery arbitrages time-of-use tariffs at night. Combined, the two halve your consumption and demand charges — designed, financed and maintained by SolarXgen, South Africa’s most experienced commercial PV + BESS partner.

Why PV + BESS beats either alone
Solar pays your day. Battery pays your peak.
Cheap daytime power from your roof
Solar covers 50-70% of weekday consumption directly — at a levelised cost roughly half what Eskom charges, with zero exposure to NERSA tariff hikes.
Battery kills your peak demand bill
BESS shifts evening peaks off the grid. Combined with PV, your maximum demand charge drops 40-60% — often the single biggest line on a C&I bill.
5-7 year payback, 25-year asset
Solar panels carry 25-year linear performance warranties. LFP batteries last 15-20. PV + BESS together pay back before mid-life — and keep paying for the next decade.
How PV + BESS arbitrage works
Generate. Store. Discharge at peak.
South Africa’s time-of-use tariffs and kVA demand charges punish evening peaks. PV gives you free daytime power; BESS lets you skip the expensive peak windows entirely. Together they typically halve a C&I electricity bill.
Generate by day
Solar produces during business hours. Direct consumption first, surplus charges the battery — no grid involvement, no tariff exposure.
Store the surplus
Battery captures solar overflow plus any cheap off-peak grid hours. Sized to cover your peak-period demand profile.
Discharge at peak
Evening peak windows and kVA demand spikes pull from the battery. Grid imports drop to off-peak hours only — at the cheapest tariff bands.
Real installation
5,068 kWp solar at Stibium Mine, Limpopo
SolarXgen’s largest project to date — a 5MW ground-mount solar array generating over 8.7 GWh annually with an 83.1% performance ratio. The site is now ideal for a BESS layer to capture surplus generation and arbitrage time-of-use windows. Mining loads, peak demand exposure and tariff escalation are exactly where PV + BESS delivers the strongest combined ROI.
