Calculating potential return sensibly. This guide is for Northern Ireland homeowners considering solar electricity or storage, and the details should be checked against their own property and current local arrangements.
Why this matters for Northern Ireland homeowners
Simple payback divides an upfront cost by estimated annual financial benefit, but both parts require scrutiny. Savings can depend on use patterns, tariffs, exports and maintenance.
What to check before making a decision
Model at least a base case and a cautious case. Separate self-consumed electricity from exported generation, and avoid assuming all units receive the retail import rate.
Questions to put to an installer or provider
Include financing charges where relevant and allow for equipment replacement or service costs. The shortest forecast is not automatically the most reliable.
Practical checklist
- Keep a copy of your electricity usage and recent bills.
- Ask for a written explanation of equipment, exclusions and assumptions.
- Confirm relevant Northern Ireland requirements before paying a deposit.
- Compare at least two detailed options where practical.
- Retain your quotation, warranties and handover records.
