Why photovoltaics

Photovoltaics is a technology that converts light energy generated by the sun directly into electricity using photovoltaic cells placed on solar panels. This energy can be used to power homes, businesses, schools, and other consumption points. The equipment that makes this happen is a photovoltaic power plant

Producing clean energy. It helps reduce greenhouse gas emissions and dependence on fossil fuels.
Protecting the environment. Produces no emissions during operation, which contributes to environmental protection.
Energy independence. Helps reduce dependence on energy imports and strengthens the country's energy independence.
Cost saving. Helps reduce electricity costs for households, businesses and other organisations.
Diversification of energy sources. Contributes to the diversification of energy sources and reduces the risk of dependence on a single energy source.

Why photovoltaics from RMC s.r.o.:

We are a qualified company operating on the Slovak and foreign market in the field of research, production and manufacture of electronics since 1994.
We have been operating in the field of photovoltaics on the Slovak market for 15 years.
Our company has its own team of qualified workers with the necessary knowledge, education and experience in the field of photovoltaic equipment installation.

RMC employs an experienced team of technical support staff with knowledge in the field of in-house development of electrotechnical equipment that can solve even complicated installations.

We hold a certificate for installers of photovoltaic and solar thermal systems issued by the Ministry of Economy of the Slovak Republic.
In addition to the development and production of electronics, our company has long been involved in photovoltaics and has carried out numerous installations on various types of buildings and houses from 1.5 kW to 100 kW.
We also have our own power plants, which allows us to accurately track the performance from period to period and assess the suitability of the technical parameters – while keeping up-to-date with the latest information in this field. In Nová Dubnica we operate 3 independent power plants on our premises, ranging from 5 kW to 15 kW, and in Trenčín we have long owned a 100 kW power plant, so a personal tour is possible if you are interested.
Our power plants meet all electrical standards, fire safety requirements, protection of the power grid against overvoltage, protection of objects and most importantly the requirements for the safety of you and your loved ones.
We work with panels and inverters from reputable manufacturers and use only original tools and components.

What is the implementation procedure:

When you contact us by e-mail or phone, you will be contacted by our employee with whom you will arrange a personal meeting.
After mutual agreement, our employee will come to make a preliminary inspection of the installation site. Several factors are decisive in determining the price, so we do not determine the final price from the table. A site inspection of the PV installation site is always necessary!
We will develop a proposal for an optimal solution taking into account the individual customer's needs, which you will receive free of charge with a quotation
The annual consumption, the condition of the current wiring, the condition of the lightning system, potential shading, the layout of the installation (e.g. roof pitch and azimuth ), the condition of the roof and other installation tasks necessary for connection to the distribution system are assessed.
The design shall include a calculation of the monthly, annual power output of the plant and a calculation to minimize system losses for the specific plant implementation
We will prepare a quotation for the installation of the photovoltaic power plant or offer alternative solutions.
We will draw up a contract for the work after accepting the quotation
After you sign the contract, we will sign together a power of attorney for concluding contracts with the distribution company, the electricity supplier and the building authority at the location of the power plant installation.
We will then arrange the relevant contracts with the distribution company and the building authority.
Once the reserved capacity has been approved by the distribution company, construction will follow, taking care to interfere as little as possible with your privacy.
After the system has been brought back to life and the necessary parameters have been measured, we will train you to operate the installed equipment.
We will then have an inspection report drawn up.
If you wish, we will handle all the administrative formalities associated with the power plant in addition to the construction.
We will inform the distribution company about the commissioning of the new power plant.
After commissioning, we closely monitor the undesirable conditions of the power plant equipment remotely and, if necessary, we will visit you and resolve any complications.
At the end, you will receive copies of all project contracts and inspection reports.

Execution Examples

Basic information about photovoltaics

What is it like in practice?

The legislation of the Slovak Republic is set up in such a way that an energy consumer can connect their photovoltaic plant with the electrical grid after fulfilling the technical conditions. In this way, they can achieve a situation where they do not take energy from the grid during sunshine, but from the solar power plant. Excess energy from the sun can be stored in a chemical battery or in a virtual battery.

The chemical battery has a capacity sized so that the daily surplus of energy produced can be used in the evening or at night. A chemical battery increases the cost of the investment by 20 to 40%

A Virtual Battery is essentially a contractual relationship between an energy consumer (house) and an energy supplier (e.g. SSE, a.s.) that allows the unconsumed energy from a solar power plant to be passed on to the supplier free of charge. In periods without sunshine (night, cloudy, winter period), you take this energy back from the energy supplier at a significantly discounted price – only paying distribution charges. The virtual battery significantly increases the availability of the power plant, but does not increase the investment costs.

How is the power plant capacity sized?

Correctly choosing generation capacity has a major impact on the return on investment. Therefore, any project plan must be backed up by a calculation of the planned consumption and an informed estimate of the payback. The main factor of payback is the current and expected energy price on the market. A low – subsidised – energy price in Slovakia prolongs the payback, but a possible state subsidy for the construction of the power plant shortens the payback. The payback period of a power plant is significantly shortened by new green electricity appliances such as chargers for electric cars, household air conditioners and heat pumps. Currently, the payback period for households ranges from 5 to 15 years, depending on the above factors. The technical lifetime of a power plant is 25 to 30 years.

What can be the maximum installed capacity of a photovoltaic power plant?

The current Slovak legislation allows the installation of power plants for households and businesses with a maximum capacity of 10.8 kW. In the case of companies, it is possible to use the power plant's capacity up to the maximum reserved capacity allocated to the business entity by the distribution company.

What is the difference between an Off-grid and On-grid solution?

Off-grid solution, the PV power plant is not connected to the public distribution grid, in this case the power plant operates as an independent island system. It is especially suitable for buildings with smaller consumption, e.g. holiday properties.

On-grid solution, the PV plant is connected to the public distribution grid, suitable for households and businesses
