Frequently Asked Questions
What size commercial solar system do I need?
This depends on your business's energy usage, operating hours, and available roof space. Jousto commercial estimates are sized to your actual consumption data.
How long is the payback period for commercial solar in SA?
Commercial systems in SA typically pay back in 2–4 years due to higher energy consumption and larger STC entitlements.
Do commercial solar systems require network approval?
Yes — systems over 30kW require network connection approval from SA Power Networks. Your Jousto estimate will flag applicable connection requirements.
Can I get battery storage with commercial solar?
Yes. Commercial battery systems (typically 30–200kWh) pair well with large solar installations to reduce demand charges and provide backup power.
