Solar PV panels will operate even if they are not orientated towards the south. We have found that panels at a lower angle will produce more power over the year. It has always been thought that panels must be south and south only. This is a myth. We have solar installed on our offices and showroom, and they are north-east and north-west. They are performing really well. Don’t get us wrong, we are not advocating putting all panels on a north roof, we did it because that was all we had, but it proves that solar works from light. A solar PV panel installation causes minimum disruption to the home or business and systems can be retrofitted. A typical silicon cell is quite small, approx. 100mm x 100mm square. Solar cells produce electricity at low voltage but when more power is required a number of cells can be connected together to create photovoltaic modules, or solar PV panels.
Solar PV panels that are connected together in series are often referred to as an ‘array’. A grouping of solar PV panels can be fitted in different configurations depending on the local conditions e.g. to follow the shape of a roof or to avoid a roof light. Solar advancements mean that using certain technology we can install panels in any location, and they work individually, so shading is no longer an issue. Solar PV panels usually have a backing sheet that is opaque, but the backing can be transparent, allowing some light through and creating a dappled effect.
Here at The Energy Guys we offer Solar PV systems in a number of standard sizes, with solar panels from major manufacturers, and may be mounted to many different types of roof surfaces and vertical facades. We provide services and solutions to all sectors of the construction industry including, specifies, developers and contractors.
On grid means that the solar PV system is connected directly to the national power grid through your mains domestic supply. This means you can export excess electricity back into the grid and trade this electricity which will allow you to quickly receive payback on your installation.
An off-grid system means that it is not connected to the national power grid, this may be because there is no electrical power supply to the property. In this case the power will be stored in lithium batteries and a small generator will act as the grid meaning you are never without power.
