How to Sign up For Solar Consultancy 

If you'd like to sign up to either a free or paid package, the easiest thing to do is give us a call or fill out the form below to request a call back. On the call, we can answer questions that you may have about the packages as well as take payment or provide bank details for a BACS transfer if necessary. While you're on the phone, we may as well start the solar consultancy process as well...

Starting Solar Consultancy

We always start with a conversation on the phone to discuss the project through with you and get an understanding for what you're looking for. If you've paid for a package, we will get any information that we need from you down the phone and then start the design work.

With this package, you will get a direct line to one of our technical designers who will be able to answer any questions as well as give advice. You can call/email as many times as you like as well as ask as many questions as you want. 

The designer will also be able to look over any designs/proposals that you may have received and they can comment on the kit, design, installation method, and price.

The Plus Package

With our Plus Package, you will get access to everything in the free package, as well as the design & modelling work listed below. You'll be able to request as many design iterations from us as you like so that we can nail down on the best system for your home. 

The price for the Plus Package is £150.

Here's a list of everything that you'll get if you sign up to this package:

  • The Free Package.
    • A direct line to your own technical specialist & designer.
    • We will look over any proposals that you've received and give our opinions & comments.

  • CAD modelling to design the PV system and work out how many panels can be fit on the roof / ground mount.
    • A full layout, with 3D download available.
    • System measurements available.

    • Modelling for how the IRR changes based on different electricity inflation rates.
    • Financial benefit breakdown.

The Advanced Package

Our Advanced Package is designed for those that want to go into greater detail to get the most accurate modelling. See a full list of benefits below.

We will provide a report with models for everything from your half-hourly electricity usage, EV usage, export limitation, & cable run voltage drops to whether it's better to orient the panels in portrait or landscape due to the layout of the internal bypass diodes. Along with a lot of other benefits, you'll also get a full shade model report that tracks the path of the sun for every minute of the year and predicts how the panel irradiance will be affected as a result. It even predicts leaf fall!

With our Advanced Package, you will get access to everything in the Free & Plus packages, as well as the advanced design & modelling work listed below. You'll be able to request as many design iterations from us as you like so that we can nail down on the best system for your home. 

The price for the Advanced Package is £450.

Any PV / Battery system that is above 3.68kW per phase will require a DNO (G98/G99/G100) application to be completed prior to installation.

The application requires all relevant kit certification as well as the completed G98/G99 /G100 form and electrical schematic.

The application will let you know how big of a solar & battery system that you can install as well as how much you're allowed to export.

We will apply on your behalf for £100.

Our Head of Installations will do a full technical & structural survey at your house. The structural survey is then sent off to an external structural surveyor for a full report with loading calculations.

The technical survey will include:

  • Measurements & assessment of relevant roof spaces to confirm how many PV modules will fit.
  • Structural survey measurements.
  • Planning & discussion for kit locations.
  • Cable run planning.
  • Electrical measurements & survey.
  • Planning for any scaffolding.
  • Planning for installation.

The price for the Technical Survey & Structural Loadings Report from an independent specialist starts at £550, depending on travel time.

We can help out with your planning application by providing any drawings and technical documents required by the council. Please let us know what you need and we will give you a price and lead time for the works.
