How Commercial Solar Works
Your 7-Step Journey from Consultation to 25+ Years of Energy Savings
At GreenWatt Energy, we believe commercial solar does not need to be complicated. Our proven 7-step process makes it straightforward, transparent, and tailored to your business. From your first consultation through decades of monitoring and support, we handle every detail so you can stay focused on running your business.
The 7-Step Process

01. Initial Consultation & Assessment
We meet with you to understand your energy needs, discuss your goals, and assess your facility. We review:
- Your annual electricity consumption and usage patterns
- Current energy bills and seasonality
- Roof condition, orientation, and available space
- Local shading and environmental factors
- Business goals including savings, ESG, and energy independence
Typical timeline: 1-2 weeks

02. Feasibility Study & Solar Modeling
Our engineers conduct a detailed analysis using industry-leading solar modelling tools to:
- Model local solar irradiance and seasonal variations
- Analyse your consumption patterns month-by-month
- Design system scenarios around your usage profile
- Forecast production, export, and savings accurately
- Prepare a feasibility report with ROI projections
Typical timeline: 2-3 weeks

03. Custom System Design
Based on the modelling, we design your optimal solar system and:
- Specify system size to match your consumption and budget
- Select premium components including SolarEdge, Sunsynk, Aiko, and Jinko
- Design electrical architecture and mounting layouts
- Create detailed technical drawings and specifications
- Provide written quotations with clear pricing
Typical timeline: 1-2 weeks

04. Grants & Incentives Planning
We maximise available funding to reduce upfront investment by helping you to:
- Identify grants and incentives you qualify for
- Prepare applications and supporting documentation
- Liaise with grant agencies on your behalf
- Structure financing to optimise tax benefits and cash flow
- See the cost picture with and without grants
Typical timeline: 2-4 weeks depending on grant agency

05. DNO & Planning Approvals
We manage all regulatory approvals so you do not have to worry about:
- DNO application and grid connection approval
- G98 and G99 compliance where required
- Planning permission coordination if needed
- Regulatory correspondence and technical submissions
- Fast-tracking approvals through established processes
Typical timeline: 2-6 weeks depending on DNO

06. Professional Installation & Commissioning
Our installation team brings the design to life through:
- Full project planning with your facility team
- Professional installation with minimal operational disruption
- Electrical testing and safety inspections
- System commissioning and performance verification
- Staff training on monitoring dashboards and operation
Typical timeline: 2-4 weeks depending on system size

07. Monitoring & 25+ Year Support
Your system is only the start. We provide ongoing support that includes:
- Real-time monitoring via export management software dashboards
- Performance optimisation and alerting
- Annual system maintenance and inspections
- 25-year panel warranty and long-term component support
- Insurance-backed workmanship warranty
Typical timeline: Ongoing 25+ year support
