Each solar photovoltaic system needs to be designed to suit both the premises and individual needs of the end user, whether for a business or a home. This involves analysing the user’s consumption profile and designing an efficient solution.
Solar panels have to be connected to each other in series and the nature of the silicon crystalline technology is that if one panel is shaded, the performance of the whole electrical circuit is affected, not just the individual panel. For this reason, it is an essential part of a proper solar design that shade analysis be conducted in the exact location where the solar panels are to be placed. Shade analysis needs to be carried out by a suitably qualified technician with appropriate equipment. Subtle adjustments to the positioning of solar panels can dramatically affect the performance of the solar system for decades to come.
Solar photovoltaic panels generate Direct Current (DC) electricity when exposed to light, but for most applications, the electricity needs to be converted to Alternating Current (AC). It can then be used to power AC appliances or interface with the electricity grid. This requires an inverter.
To operate at optimum efficiency, the panels have to be connected in certain configurations to match the input voltage requirements of the inverter. The panels need to be attached to the roof of the building or ground mounted with purpose built railing equipment.
The design process needs to be carried out by a technician experienced in the art of solar design, while the installation needs to be performed by fully qualified and accredited tradesmen.
