How Long Does the Solar Panel Installation Take? 

One of the first things homeowners ask us at MAKSE Electrical & Renewables is simple:
“How long does the solar panel installation actually take?”

Good news: the physical installation on your roof is usually done in just 1–2 days.
But the full process, from your first enquiry to switching on your new system, typically takes around 4–8 weeks, depending on design, permissions, and equipment lead times.

This blog breaks the whole journey down into clear, human-friendly steps so you know exactly what to expect.

The Complete Solar Installation Timeline in the UK

Below is an easy overview of the seven main stages:

• Initial consultation
  
• Home survey
  
• System design
  
• DNO approval
  
• Installation day(s)
  
• Testing & commissioning
  
• Final connection & export setup
  

Let’s dive deeper.

Step-by-Step Breakdown

1. Your First Enquiry (1–3 Days)

The process starts when you contact us through the MAKSE Electrical & Renewables website. We ask a few simple questions:

• Your roof type
  
• Your energy usage
  
• Any shading issues
  
• Whether you want battery storage
  

Our team reviews your needs quickly so we can book a site visit at a time that suits you.

2. Site Survey & System Design (1–2 Weeks)

A member of our qualified team visits your property. We check:

• Roof structure and direction
  
• Cables and consumer unit
  
• Location for the inverter
  
• Space for batteries (if added)
  

3. DNO Approval (2–6 Weeks)

Before connecting your solar system to the national grid, your local Distribution Network Operator (DNO) must approve it. This ensures the network can safely handle your export.

Approval can range from a few days to several weeks, depending on:

• Your local DNO
  
• System size
  
• Household grid demand
  

This is usually the longest stage but don’t worry, MAKSE Electrical & Renewables handles all the paperwork for you.

4. Equipment Ordering (3–7 Days)

Once your design is locked in, we order your:

• Panels
  
• Mounting kit
  
• Inverter
  
• Battery (optional)
  
• Safety switches & monitoring tech
  

We work with reputable suppliers, so equipment delays are rare but larger commercial systems may take longer.

5. Installation Day(s) – The Exciting Part (1–2 Days for Most Homes)

This is the part everyone looks forward to.

A typical UK home takes 1 to 2 days to complete:

What happens on Day 1?

• Scaffolding goes up
  
• Mounting rails are fixed
  
• Panels are installed
  
• Cables are routed neatly to the inverter
  

Day 2 normally includes:

• Inverter and battery installation
  
• Electrical connections
  
• Final panel checks
  
• System activation tests
  

Flat roofs, slate roofs, and very large systems may take an extra day but our team works efficiently and safely.

6. Testing, Commissioning & Handover (1 Day)

We run safety checks, confirm voltage levels, and connect your inverter to your monitoring app.
You’ll see real-time generation on your phone a moment customers always enjoy.

We also walk you through:

• How your system works
  
• How to track savings
  
• What to expect on sunny and cloudy days
  
• Battery tips (if included)
  

7. Final Sign-off & Export (1–2 Weeks)

Once live, your system is inspected and certified.
If you want to earn money from selling your excess energy back to the grid through the Smart Export Guarantee (SEG), your energy supplier may need to update your meter. This can add up to 2 weeks, depending on the supplier.

What Affects the Installation Speed?

A few factors can shorten or lengthen the timeline:

• Roof type clay, slate, or tricky angles may take longer
  
• DNO response time varies by region
  
• System size larger arrays need more fitting time
  
• Battery installation adds wiring time
  
• Weather delays for safety reasons
  

At MAKSE Electrical & Renewables, we always communicate clearly so your expectations stay realistic.
