Solar panels comprise of many, smaller units called photovoltaic cells. (Photovoltaic simply means they convert sunlight into electricity.) Each photovoltaic cell is basically a sandwich made up of two slices of semi-conducting material, usually silicon. Each module/solar panel is made up of multiple photovoltaic cells. When sunlight shines on the solar cells, in the form of irradiance, electrons in the silicon are agitated. The agitation causes the electrons to want to move, creating a direct current flow of electricity. Simply put, a solar panel works by allowing photons, or particles of light, to knock electrons free from atoms, generating a flow of electricity.
This passes through an inverter, changing it to alternating current, to be able to be used by everyday electrical equipment. The solar electricity is then used in real-time by your business or organisation. Any unused electricity may be stored by a battery, if you have one, or released to the grid
Yes, for all grid-tied solar solutions an application process is required by your local utility supplier. Application and conditions differ from supplier to supplier.
For off-grid solutions, no permission is required (based on current requirements).
In general, systems over 10kW will require three phase connections. Get in touch with a member of our technical team for more information.
Since all our commercial solar installations are bespoke, the duration of projects can vary. It depends on size, energy demand, and whether things like approval or planning permission are required. In general, the process can take anywhere between one and three months. However, once our team is on-site, it takes roughly just five days to install a 50kW system.
There are benefits to both ground and roof-mounted solar panel systems – it all depends on the individual requirements of your organisation.
Roof-mounted solar panels are the most common choice for businesses. They are cheaper to install, as you don’t have to build a structure or foundations to mount them. They also take up less space, and utilise an otherwise unused space to generate electricity, save you money, and safeguard the environment.
If your roof space is unsuitable for PV panels, your business can still benefit by generating its own solar electricity. Ground-mounting your solar panels gives you greater control of how you orientate your array, and makes it easier to troubleshoot and repair any issues. Ground-mounted solar panels also generate slightly more energy, as air circulating under the panels keeps them cool – increasing their efficiency.
