The D&R Energy Solar Installation Process

Your solar journey begins with a free, no-obligation consultation. Call us on 0800 772 0758 or complete our online form. During this initial conversation, we discuss your energy goals, typical monthly electricity usage, roof characteristics you are aware of, and your budget. We will give you a ballpark estimate for your property type and answer any questions you have.

• Discuss energy goals and current bills
• Understand your property and roof type
• Explain available packages and options
• Provide an indicative price range
• Arrange a convenient survey date

A qualified D&R Energy surveyor visits your property at a time that suits you. The survey typically takes 45–90 minutes and covers every aspect of your property relevant to a solar installation. We assess your roof structure, orientation, pitch, and condition; carry out a detailed shading analysis using professional tools; inspect your consumer unit and electrical installation; measure roof dimensions and map out the optimal panel placement; and assess any cable routing requirements.

• Full roof structural and condition assessment
• Shading analysis using professional surveying tools
• Consumer unit and electrical capacity inspection
• Precise roof measurement and panel layout mapping
• Cable routing and inverter location planning
• Planning and permitted development assessment

Using the survey data, our design team creates a bespoke solar system specification for your property. Every system is designed individually — we do not use template configurations. The design includes the precise panel layout, inverter specification, battery capacity recommendation, cabling plan, and generation and savings projections based on your specific roof orientation, shading profile, and electricity usage patterns.

• Bespoke panel layout for your exact roof
• Inverter and battery specification
• Generation forecast based on your orientation and postcode
• Annual savings projection with and without battery
• Full itemised quote with no hidden costs
• Finance options clearly presented

Once you have reviewed and approved your personalised quote, we confirm your installation date and begin preparing your system. We order the specific equipment for your installation, confirm scaffolding requirements and book the scaffolding contractor if needed, and submit the DNO (Distribution Network Operator) pre-notification if required for your system size. Most systems are installed within 2–4 weeks of quote approval.

• Equipment ordered specifically for your system
• Installation date confirmed
• Scaffolding arranged if required
• DNO pre-notification submitted if required
• All paperwork prepared in advance

Our installation team arrives at the agreed time and carries out the full solar PV installation. A standard domestic system takes 1–2 days to complete. The team erects scaffolding if required, installs the roof mounting brackets and rails, mounts the solar panels, runs all cabling through the property to the consumer unit location, installs the inverter (and battery if included), and connects and tests the entire system before leaving.

• Scaffolding erected if required (day prior or same day)
• Roof mounting system installed
• Solar panels mounted and clamped
• Internal cabling and conduit installed neatly
• Inverter and battery installed in agreed location
• System commissioned, tested, and verified
• All work areas cleaned and left tidy

After installation, D&R Energy handles all post-installation paperwork on your behalf. We issue your MCS (Microgeneration Certification Scheme) certificate within 5 working days of installation completion. This certificate is essential for registering for the Smart Export Guarantee. We also complete the formal DNO notification and provide you with all the documentation you need for building regulations, insurance purposes, and future property sales.

• MCS certificate issued within 5 working days
• DNO formal notification submitted
• Building regulations notification if required
• All warranty documentation provided
• Smart Export Guarantee registration guidance

Before leaving your property, we walk you through your new system in full. We show you how to monitor generation and consumption through the inverter or battery app (available on iOS and Android), explain what different system modes mean, show you how to set up automated overnight grid charging if you have a battery, and answer any questions you have about maximising your savings. You will leave the handover confident in operating your new system.

• Full system operation walkthrough
• App setup and monitoring explained
• Battery charging schedules configured
• Smart Export Guarantee registration guidance
• Ongoing support contact details provided
