Solar panel installation

Your PV Fit solar energy system will usually take 1 day to install.

Here’s a quick guide on what to expect before, during and after the installation of your equipment…..

What do you need to do before going ahead with your PV FIT installation?

Planning Permission – PV panels are usually classified as “permitted development” if they project less than 200mm from the roof level. Therefore you should not require planning permission unless you live in;

  • a conservation area
  • an Area of Outstanding Natural Beauty (AONB)
  • a national park
  • or your property is listed

In all cases we recommend that you contact your local planning office to confirm they have  no objections before going ahead with your installation. Locate your local planning office.

Commercial solar no longer require planning permission unless ground mounted, or the panels project more than 1000mm above the highest point of the roof.

Energy Performance Certificate (EPC) – If you do not already have one we will arrange for an EPC survey to be conducted for your property. Your EPC must demonstrate that your property achieves a level D or above with the pv system installed. If it doesn’t you would not qualify for the highest FIT rate relevant to your proposed system size.

Structural Assessment – We will also arrange for a structural assessment of your roof to ensure that it can accommodate the added weight of your solar panels.

Don’t worry if your unsure what to do, we will handle everything for you!

A typical domestic installation will consist of:

  • 10-16 PV panels on a sloping South facing roof
  • Your PV panels will sit on top of your existing tiles or slates
  • An Inverter, which converts solar electricity from Direct Current (DC) into Alternating Current (AC) which can be used in your home, will be installed in your loft, utility room or garage
  • A cable will run from your inverter, either internally or externally, to the location of your consumer unit (fuse box) where it is then connected to a spare circuit (spur)

On arrival, your installer will complete safety checks of access equipment, a risk assessment of all working areas and lay out protective sheets in the areas that they are working. Your engineer will also agree with you the location of your solar panels, inverter and cable routes to ensure the aesthetics and practicality of access are right.

Roof Work

Your solar panels are fixed to the roof using brackets that hook under your tiles/slates to avoid penetrations. The brackets are screwed directly onto the rafters, or to over the battens in cases such as the “Click Fit” system. Rails are then secured to the brackets, with the solar panels then fixed on top. There will be a gap between your roof and the panels to allow for drainage and airflow.


Your inverter is usually mounted on a wall near to the solar panels, typically in your loft. Cables will run neatly through the roof via a weatherproof flashing where they then connect onto the inverter. A single AC cable then drops down to your consumer unit (fuse board) where your PV system connects to the mains grid. Your OFGEM generation meter is also located here to make it simple for you to take meter readings when claiming FIT payments from your energy supplier. See our case studies for installation photos.


On completing your installation, we will provide you a handover pack containing your user guide, a system drawing, test certificates and warranty documents. Your engineer will make sure you are familiar with your pv system and will ensure that all working areas are as clean as when we arrived. All waste packaging is removed and recycled where possible.

We will then help you complete your feed in tariff application form and issue you with your MCS certificate and paid invoice as evidence you own your solar pv system.

*In vast majority of cases you will keep your existing electricity meter, however your electricity supplier needs to confirm whether they wish to replace your meter. We would not usually be involved with swapping out main import meters but we are happy to liaise with your electricity supplier on your behalf should you wish us to.
