Commercial Solar PV — How It Works
Rooftop array to grid · Zero upfront cost · Fully managed
Solar Panels
Capture sunlight and generate DC electricity.
Inverter
Converts DC electricity to AC electricity.
Meter
Measures the electricity exported and imported.
Building Load
Powers your business operations.
Utility Grid
Excess electricity is exported to the grid.
Commercial Solar & Battery Technology In Action
From industrial rooftop array mounting to modular commercial battery storage and accredited site engineering.
Rooftop Transformation
Unlocking unused commercial roof space into an active clean energy asset yielding substantial bill savings.
Accredited Installation
MCS-compliant and NAPIT-certified electrical engineers managing structural framing and grid connection.
Modular Battery Storage
Storing daytime solar generation to power peak evening operations and maximize self-consumption.
How you pay for what we deliver
The Tier-1 solar panels and battery hardware installed by Portcullis Power Solutions are identical whichever route you choose. What changes is who owns the asset, how it sits on your balance sheet, and how quickly you realise cash savings.
Buy Outright
Capital purchase. You own the system outright from day one.
- Upfront cost
- Full system capital cost
- Who owns it
- Your organization
- Savings
- 100% of generation & export income from day one
- Best for
- Businesses with available capex seeking maximum long-term ROI
Asset Finance
Spread the cost over a fixed term while owning the asset.
- Upfront cost
- Deposit or £0, depending on facility
- Who owns it
- You do, subject to finance terms
- Savings
- Monthly energy savings offset the finance instalment
- Best for
- Businesses wanting asset ownership with 100% tax expensing
Power Purchase Agreement
Zero capital outlay. You buy the electricity, not the equipment.
- Upfront cost
- £0 Capital Expenditure
- Who owns it
- PPA Provider (transfers to you for £1 at term end)
- Savings
- Pay a discounted unit rate locked long-term below grid tariffs
- Best for
- Sites with daytime load wanting zero capital cost or risk
Everything from design to generation, managed under one roof
Every commercial system is engineered for your building by accredited partners — roof capacity, orientation, shading and your 12-month half-hourly consumption.
1. Tailored solar PV design
Precision-engineered against 12 months of half-hourly data to match your daytime operational load.
2. Accredited installation
Installed to strict UK electrical standards by MCS-certified partner engineers, with full structural and electrical sign-off.
3. Commercial battery storage
Stores daytime surplus for evening and peak-rate hours, maximising the electricity you use yourself.
4.Live generation & carbon analytics
Real-time generation and battery data feeds directly into your Scope 2 ESG carbon reporting.
5. Smart Export Guarantee (SEG)
Export surplus electricity you don't store for extra revenue. MCS certification is what makes SEG payments claimable.
6.Lifetime servicing & maintenance
Periodic checks, inverter health reviews, electrical testing and warranty support by partner engineers.
7. Workplace EV charging integration
Pairing solar panels with workplace EV charging points to power commercial fleets and employee vehicles directly.
Five steps, from review to generation
Consumption review & feasibility
Send 12 months of electricity bills. We analyse your volume, import tariffs and daytime usage to model the financial return before anything is committed.
Roof & site survey
A full inspection covering roof condition, orientation, shading, incoming supply and switchgear capacity — the checks that catch problems before they cost money.
Engineering design & 3-way funding proposal
One engineering design featuring Tier-1 arrays, modular battery storage and optimized inverters, costed three ways — outright, asset finance or PPA — with performance modelled from your own consumption data.
DNO connection & installation
Grid applications handled, and installation scheduled around your operating hours by accredited engineers to keep disruption to a minimum.
Monetising carbon credits & reporting
Monetising carbon credits from clean energy generation, verifiable Scope 2 ESG carbon reporting data, real-time generation monitoring, and Smart Export Guarantee (SEG) setup for ongoing revenue.
Solar cuts the emissions you report to stakeholders
Generating clean power on-site directly cuts grid imports — which forms the exact foundation of your annual Scope 2 reporting figure. Our monitoring systems provide verifiable generation data that corporate auditors and client ESG procurement teams accept.
What it doesn't do is create tradeable offset credits. UK rooftop solar isn't eligible under corporate offset standards — anyone offering both bill savings and carbon credit income is double-counting the same electricity.
