What if your business could reduce electricity costs without tying up valuable capital?
As energy costs influence operating margins and business growth, commercial and industrial organizations are aggressively exploring solar power. However, financial considerations play a crucial role in determining a business's transition to solar energy: should you invest in and own a solar power system or purchase solar energy without the upfront investment? This is where CAPEX and OPEX solar models come into play, offering businesses two distinct approaches to adopting solar energy.
Understanding CAPEX Solar
This model facilitates a business to invest and own its solar power system. The investment encompasses equipment, engineering, installation and commissioning.
Key benefits
- Complete ownership of the solar installation.
- Greater control over the energy asset.
- Potential long-term electricity cost savings.
- Flexibility in managing the system.
OPEX Solar Explained
OPEX solar model typically allows a solar developer to invest and own the solar system. The business purchases the electricity generated at a mutually agreed tariff through a Power Purchase Agreement (PPA), without making a substantial upfront investment.
Key benefits
- No major upfront investment.
- Preserves working capital.
- Access to renewable electricity.
- Developer-managed maintenance, as agreed.
CAPEX vs OPEX: Understanding the Difference
| CAPEX Solar | OPEX Solar |
|---|---|
| Business invests in the solar system. | Developer typically invests in the system. |
| Business owns the solar asset. | Developer typically owns the solar asset. |
| Higher upfront capital requirement. | No major upfront investment. |
| Business manages the asset or appoints an O&M partner. | Developer typically manages O&M as agreed. |
Which Model Is Right for Your Business?
CAPEX may suit businesses with available capital that prefer asset ownership and greater control. OPEX may be better for organisations looking to preserve capital while procuring renewable electricity. The right choice depends on energy consumption, project feasibility, financial priorities and contractual terms.
