How PV solar panels work
Every solar PV system is made up of several components: solar panels (or ‘modules’), an inverter, a meter and your existing consumer unit. Zoom in on the diagram below to see how it’s all connected and understand how solar panels work.
We recommend that you contact your local planning office to confirm there are no objections to your installation and we will be happy to help with a planning application on your behalf, should one be required.
Fully MCS certified installation
We are highly experienced, professional, installers of both residential and commercial solar PV systems.
External roof work
The solar panels are fixed to your roof using brackets that hook underneath the tiles or slates and are screwed directly onto the underlying wooden roof structure. The panels are then secured to these brackets on a series of aluminium rails, with an air gap between your roof and the panels to allow for free drainage and airflow.
This fixing system means that there is no compromise to the roofs weatherproofing integrity and, of course, all of our work is fully insured and guaranteed.
PV installation takes a maximum of two days, with very little disruption to your normal domestic routine and minimal mess!
If we need to erect a scaffold, this will typically be done the day before installation and removed the day after… and the cost will already have been included in our quotation.
- The sun gives off light, even on cloudy days
- PV cells on the panels turn the light into DC electricity
- The current flows into an inverter, which converts it to AC electricity ready to use
- The current is fed through a meter and then into your home’s consumer unit
- Plug in and switch on. Your system will automatically use the free electricity you’ve generated, then switch back to the grid as needed
- Any electricity you don’t use is exported to the grid for others to use.
Internal hardware and wiring
We install two essential pieces of hardware inside your home…. an inverter, which converts the DC current coming from your panels into a form that your household system can use, and a meter that allows you to see, at a glance, how much energy and FiT revenue your solar system is generating.
Your inverter is usually mounted close to the solar panels, typically in the loft, fed by a cable running through weatherproofed flashing. A single cable is then dropped down to the propertys existing fuse board where it’s connected to your mains via the generation meter.
Getting the best from your system…
On completion, and after a thorough clear up, the project engineer will instruct you on the use of your new system and issue your test certificates, warranty documents and user guide.
