In cases where the cost of connection to the network is high and in cases where the use of the property is intermittent, such as use only in the summer months or use only on weekends with consumptions such as refrigerator-lights-television, the installation of an autonomous system is the best solution in most cases.

In cases where there is already a connection to the grid, an inventory of energy needs and a study by an experienced technician should be made to see if it is advantageous to have a stand-alone system or a self-generation system interconnected to the grid.

Many times we have heard of cases where they have installed a standalone system spending a lot of money and their system does not meet their needs or has constant problems.

This is true when a system has not been properly designed and dimensioned from the beginning or when the equipment selected or proposed by the installer does not meet the needs of the customer either out of ignorance or deliberately to reduce costs for the customer and worse still to increase the profit of the installer or vendor.

Unfortunately, several online stores dealing with autonomous photovoltaics promote poor quality non-branded equipment that not only does not meet basic specifications but often misleads with its technical characteristics.

By choosing branded products we ensure proper operation during the lifetime of the machines and we are sure that the money we spend corresponds to the quality promised by the manufacturer.

We choose only branded products from well-known manufacturers with proper technical coverage and from factories that have been in business for many decades.

In the field of autonomous systems, the rule “What you pay is what you get” applies 100%!!!!

Yes, but we need to know what the final desired size of the system is.

As far as the photovoltaic panels and the charge controllers are concerned, there is no problem as during the expansion we can add additional photovoltaic panels with their own controller in each group to the existing batteries.

The problem of expansion is mainly focused on the inverter, which must either be chosen from the beginning of a higher power model or, ideally, an inverter with paralleling capability.

As for the batteries in most cases we can extend them to increase the storage capacity but we must consult our technician so that the extension does not end up being unprofitable.

Under no circumstances do we place different batteries together either in type or capacity.

Do not hesitate to call the technical team of Solar-shop.gr to dimension your system together.

Having basic knowledge of electrical engineering, one can, with proper guidance, do the installation on their own after consulting an experienced technician for the selection of equipment and the points to watch out for when connecting the equipment.

However, the voltages and currents in a photovoltaic system are high and pose risks both to the destruction of the equipment with a wrong connection and to the physical integrity of the person involved with the equipment.

In any case, it is recommended to entrust the installation of the equipment to an experienced installer with knowledge of autonomous systems.

At Solar-shop we offer ready-made solutions for pre-configured and pre-regulated systems so that the end user can easily do the installation on his own with guidance from our technical department whenever required.

To properly size a system we need to know the daily consumption in KWh, the use of the system within 24 hours, the sunshine of the area where the installation is made and the instantaneous power W of the devices that will be connected.

Inside Solar-shop.gr you will find the special form we created for you that will help you to easily calculate all the requirements and choose the right equipment so that you do not spend unnecessary money and the equipment meets your needs.

By choosing branded equipment you take advantage of the solvency of the manufacturers’ warranty and their distribution and support network.

Low quality products from individual imports do not offer a proper guarantee and often not even technical support from their importers.

At Solar-shop.gr we are always at your disposal to help you in any problem that arises and provide you with pleasure which technical information you need both at the stage of product selection and after the sale as we do in our physical store Atomon – Technology year now building trusting relationships with our customers from 2006 to date.
