Solar Mounting Systems

σύστημα στήριξης φωτοβολταϊκών Κύπρος

σύστημα στήριξης φωτοβολταϊκών Κύπρος The objective for every photovoltaic system is to achieve the optimum efficiency and this can only be obtained at optimum orientation and inclination. Solar Mounting Systems help the installer to achieve this objective. Mounting Systems being used in the Solar Industry are classified in categories depending on the type of surface that the Photovoltaic System will be installed. Solar Mounting Systems being used by K-Energy Ltd are made from aluminium of galvanised steel, with 20 year guarantee.

Inclined roof systems

Photovoltaic Systems on inclined or pitched roof in Cyprus shall follow the orientation and inclination of the roof according to the Town Planning regulations. Special mounting brackets are used for the installation of the PV System above the roof tiles.

Flat roof systems

Photovoltaic Systems on flat roofs are installed on metal triangles made of aluminium, screwed on concrete blocks or directly on the roof. Such PV Systems can be optimised to return the maximum from your investment.

Roof-integrated systems

Roof Integrated Photovoltaic Systems deploy a method of installation that replaces the use of roof tiles on residential premises.

Building-integrated systems

Building Integrated Photovoltaics or BIPV are solar cells integrated in double glazing applications and are installed on buildings in place of windows or as facades. The energy generation of BIPV is limited compared to optimised photovoltaic systems on flat roofs and out in the fields, but in countries with high solar irradiation like Cyprus such systems can be feasible.

Freestanding systems

Freestanding Photovoltaic Systems are integrated on the ground in rural areas. This is the method used in large scale photovoltaic systems all around the globe and in photovoltaic parks in Cyprus. The mounting systems are made of aluminium or galvanised steel and are fixed on the ground either with the use of concrete blocks or ground pile or ground screws.

Intelligent solar tracking system

Solar Tracking Systems are metallic systems, made of aluminium or galvanised steel, which the follow the sun path either with sensors or preconfigured algorithm (based on the coordinates of the installation site). There are single or double axis systems. Single axis can move either from east to west or changing the angle of inclination of the solar module whereas the double axis system moves from east to south at various angles in order to align the cells perpendicular to the sun path. Both technologies have been used and tested in Cyprus by K-Energy Ltd and they have caused an increase in the yield of the photovoltaic system from 15-20% for single axis and 35-40% for double axis mechanisms.

Nowadays there are many good and reliable solar inverters in the market. Our experience and the high level technical know-how of our personnel leads us to the choice of the most appropriate hardware for Cyprus. We collaborate with all the leading companies in the market and through our pilot systems we test and analyse what is the best solution for our customers.

Solar Inverters

Solar Inverters

A Solar inverter or PV inverter is the most critical electrical component in a photovoltaic system. It converts the DC output of the solar panel into an alternating current that can be fed into the commercial electrical grid or used by a local, off-grid electrical network. Solar inverters have special functions adapted for use with photovoltaic strings, including maximum power point tracking and anti-islanding protection. Solar inverters are classified into two categories,

Stand-alone Inverters, usually being used in application where the connection to the electricity grid is not possible and controls the power conversion from a power storage system (batteries) to the electrical network of the premises. There are some multifunctional models that can also control the battery charging procedure through integrated solar battery charge controller.

Grid-tie Inverters, they are divided into two sub-categories, string and central inverters. Central Inverters are integrated only in large scale PV systems as their power rating start from 30kWp and up to 1MWp. The most common ones are the string inverters with power range from 3kWp up to 20kWp. Maximum Power Point Tracking system (MPPT) is a function that all the solar inverters use in order to get the maximum power output from photovoltaic module strings. Solar (PV) modules have a characteristic power output curve, also known I-V curve, which reflects the complexity of power generation and how it affected from parameters like solar irradiation, module temperature and total electrical resistance. The role of MPPT is to track these parameters and to optimise the power generation of the solar modules strings. Usually solar inverters deploy one, two or three MPP controls, depending whether it is single or three phase inverter and whether it is a string or central inverter.

The efficiency of solar inverters in the conversion of DC to AC power is being improved continuously and it has reached the level of 99%. However, in order to achieve this level of efficiency a lot of conditions need to be met. It is very important all these conditions to be considered in the design stage of the PV System. Most solar inverters are being designed and produced based on the central Europe weather conditions. Countries like Cyprus, with dry climate and extremely high temperatures over summer period can set out of operation string solar inverters with convectional cooling system.

Nowadays there are many good and reliable solar inverters in the market. Our experience and the high level technical know-how of our personnel leads us to the choice of the most appropriate hardware for Cyprus. We collaborate with all the leading companies in the market and through our pilot systems we test and analyse what is the best solution for our customers.
