What you should know before investing
Commercial installation is a coordinated construction and electrical project. Phased work may help protect operations. Commercial solar projects need decisions based on a real building survey, measured electricity use and a clearly documented project brief.
For Northern Ireland organisations, network requirements, local planning arrangements, ownership agreements and funding eligibility should all be checked for the individual project rather than assumed from information published for Great Britain or the Republic of Ireland.
Key project considerations
Electricity demand
Review half-hourly and annual electricity demand, tariff arrangements and daytime consumption.
Building suitability
Consider roof condition, structural capacity, access, fire strategy, equipment position and ownership.
Technical design
Seek clear documentation covering equipment, connection requirements and expected operational performance.
Commercial case
Examine price assumptions, maintenance, responsibilities, risk and financing over the system lifetime.
How to plan your project
Understand
Collect electricity bills, interval meter data and project objectives.
Assess
Review roof condition, access, wiring and permissions.
Compare
Ask for itemised quotes and transparent forecasts.
Decide
Agree engineering scope, delivery plan, warranty and aftercare.
Commercial installation: practical guidance
Commercial installation is a coordinated construction and electrical project. Phased work may help protect operations. Useful project decisions compare alternatives, the risks of doing nothing and the full scope of any proposed work.
Request evidence that forecasts and assumptions are based on the proposed site. Business energy use varies according to sector, operating hours and production plans. Do not treat headline savings estimates or grant information as guaranteed.
Information to gather
- Recent energy bills and interval consumption where available.
- Roof plans, building age and ownership or lease details.
- Electrical drawings, existing supply and potential export restrictions.
- Operational constraints, budget and expected project timetable.
Frequently asked questions
Is this suitable for every Northern Ireland business?
No. Suitability depends on site-specific roof, electricity, network and financial information.
How do we compare installation costs?
Ask for comparable scopes and written equipment, installation and maintenance provisions.
Are grants or funding guaranteed?
No. Funding programmes and eligibility can change; confirm the current terms directly with the administrator.
Do we need a grid assessment?
Potentially. The need and scope depend on proposed export, electrical connection and local network requirements.
Can we include battery storage?
Yes, where technically appropriate, but sizing and financial value require actual business demand data.
What should we do first?
Collect your building and energy information, then arrange an appropriate site-specific feasibility assessment.
