Good systems start with a good design

 Before we sell you panels or a battery, we work out what your home actually needs - and what the system will really do for you.  You don't need to become a solar expert. You need clear answers about your roof, your electricity use and the way you want your home to work. 

Get in Touch

Whole-home design

Start with a home energy design. Bring your electricity bills, your questions and your future plans. We'll work out what makes sense for your home. 

Engineer-led

Our  approach combines knowledge of building fabric with practical experience in system design and installation, from ground works through to electrical installation and system integration.

A design, not a sales pitch

Our survey & design service costs £120 + VAT. You're investing in professional, engineer-led, thoughtful design before committing thousands of pounds to equipment.

Will solar actually work for my house?

How much could my roof make?

Do I actually need a battery?

Do I actually need a battery?

 We look at the roof, orientation, shading and available space - then model expected generation through the year. 

Do I actually need a battery?

Do I actually need a battery?

Do I actually need a battery?

 That depends on when you use electricity, how much solar you can make, your tariff and what you want the battery to achieve. 

What happens in winter?

What about an EV or heat pump?

What about an EV or heat pump?

 We show you that too. A good design is not based on one sunny day in June or one headline annual number.

 Your system can be designed with tomorrow in mind - without simply making everything bigger than it needs to be. 

Our job is to make the technology make sense

 We do the calculations. You get a system recommendation you can understand.

What happens to the electricity?

Sunny day

Sunny day

 Plenty to work with!  Run the home, fill the battery, charge the car if useful, then export surplus. Your report would use figures for your own property. 

Grey day

Solar still contributes.  The system may combine solar, stored energy and the grid rather than relying on one source. We show what a realistic day looks like. 

Winter

Plan for the lean days.  Lower generation is normal. Battery strategy and cheap-rate electricity can matter more. No pretending every day is July. 

A DESIGN, NOT A SALES QUOTE

OUR APPROACH “What should this home do?”

TYPICAL SALES VISIT “How many panels can we fit?”

TYPICAL SALES VISIT “How many panels can we fit?”

  • Understand your actual energy demand 
  • Model supply and performance 
  • Size storage for a purpose 
  • Consider EVs, heat pumps and tariffs 
  • Think about backup and power limits 
  • Recommend before specifying 

A design you can make a decision from


Your energy picture

Your energy picture

Your energy picture

What you use now, when you use it and the important loads in your home. 

Your roof and site

Your energy picture

Your energy picture

What's feasible, including layout, orientation, shading and installation constraints. 

Your system size

Your energy picture

Your real-world scenarios

A reasoned recommendation for solar, battery and inverter sizing - not just the maximum that fits. 

Your real-world scenarios

Your real-world scenarios

Your real-world scenarios

Expected performance through the year, with more detailed battery analysis where appropriate. 

Your future plan

Your real-world scenarios

Your next decision

EV, heat pump, backup power, diverters or other future changes considered where relevant. 

Your next decision

Your real-world scenarios

Your next decision

Proceed, change the design, phase the work - or decide it's not right for you. The analysis still has value. 

One team can design it, install it and explain it.
