Solar PPA — zero CapEx, fixed unit rate.

How a PPA works

1. You host the asset. Solar PV is installed on your roof or unused land.
2. A third-party investor owns it. They pay for design, install, commissioning, and ongoing O&M.
3. You buy the electricity it generates. Usually at 50-70% of your current grid unit rate, fixed or RPI-linked for 10-25 years.
4. At end of term, you can buy the system for a nominal sum, extend the PPA, or have it removed.

When PPAs make sense

• You don't want to deploy CapEx on solar (preferring it for core business)
• You can't access capital allowances (charity, public sector)
• You want predictable energy costs for budget certainty
• Your site has good solar potential but you don't want operational responsibility

When CapEx beats PPA

• You have cash + tax appetite (50% first-year capital allowance is significant)
• You want full ownership of the asset and all generation value
• Long-term IRR matters more than upfront cash preservation
