Solar PV is a technology which householders are now more aware of, particularly in helping them to control rising energy costs by maximising the use of the FREE energy produced from the sun. At the same time, it helps developers to comply with Building regulations / SAP requirements
Solar PV systems are extremely reliable. The PV modules come with a twenty five to thirty year performance warranty and have no moving parts so failures are extremely rare. The inverters for solar PV systems have ten year warranties as standard and these can often be extended.
Solar PV systems can be mounted on almost all roof types including tiles, slates, flat roofs, and metal roofs.
Nationwide Solar will always arrange a structural assessment of the existing roof to ensure its structural integrity.
The Nationwide design team will suggest the most appropriate equipment package to suit your roof type and style however complex the project.

An on-roof PV system will generally comprise of an aluminium framework mounted on brackets fitted through the existing roof tiles. Solar panels are then fitted to the framework to form the array. This is usually the most appropriate system for retrofit installations due to cost.
An in-roof system is where the solar panels and mounting system form part of the roof covering reducing the number of tiles required and giving a flush appearance to the finished roof.
We recommend this type of system for new build projects.

Where the installation is on a flat roof, we will usually supply a mounting system which allows the solar PV modules to be positioned at the best angle for energy production. We will need full details of the roof so that we can design suitable mountings.
For ALL new build sites, we will provide a comprehensive site guide bespoke to the specific roofing system to be utilised on a particular project. This will be provided at the pre-start meeting and sets out how our work smoothly integrates with other trades.
Interaction with other trades is clearly set out in the PV site guide. PV Installations are formed with two key components:
The site electrician is required to install and certify the supply circuit to the inverter position.
The builder will normally supply a working platform and backing board for mounting of the inverter, where this is to be situated in the loft.
- Installation of the solar panels on the roof.
- Installation of the inverter and commissioning.

Whatever the project, we will agree with you the call off requirements in advance. The longer you can programme the better however as a guide, we would normally expect ten days.
Yes, we are experienced at dealing with the G98 and G99 regulations.
We will at pre start, request from you the MPAN and Postal address and plot number of each property for new build and then based on the PV requirement of each property make the appropriate application
It can take up to sixty days to obtain approval from the DNO and so this should be carried out early in the project time line.

Nationwide Solar is MCS certified to carry out battery installations. Where batteries are included in the system design this will help to maximise the utilization of the FREE energy being generated from the solar panels.
In addition, batteries can also be used in conjunction with time of use tariffs available from many of the energy suppliers to maximise the use of the cheaper rate energy.

Under normal circumstances solar panels in the UK are designed to be self-cleaning in normal rainfall. If in a particular area or environment the panels are subjected to bird droppings or leaves, then cleaning may be required. For domestic properties many window cleaners offer this service. We advise you not to attempt to access the panels yourself as working at height is potentially dangerous.
SEG is the Smart Export Guarantee which came into effect in 2020. Any energy you generate but don’t use will be exported to the energy grid and all major energy suppliers will offer an SEG tariff. You will need a Smart Meter fitted to record the exported power. Shop around as SEG tariffs vary.

Either located within the main fuseboard or adjacent will be the generation meter which will show the cumulative generation from your system. You should be aware that the system will generate more during the summer months than in the winter.
