Photovoltaic power plants

No accumulation

A photovoltaic power plant (FVE) produces electricity that is immediately consumed or transferred to the distribution network. This installation is suitable for households and businesses that take electricity mainly during the day and therefore do not have to take it from the grid and pay for it.

With accumulation

With battery storage

The FVE plant produces electricity that is either directly consumed or stored in batteries for later use. It therefore maximizes self-sufficiency and electricity savings. Surpluses that cannot be stored in batteries are transferred to the distribution network and redeemed by the distributor. If the FVE plant does not produce (in the evening) and the batteries are exhausted, electricity is consumed from the grid. This installation is suitable for households and businesses with electricity consumption unevenly during the day or in the afternoon and evening. Such a system is also suitable as a backup source of energy in the event of a power failure.

Island system

The island system is an ideal solution for places where it is not possible to connect to the electricity distribution network, but it is necessary to use electrical appliances. The island system is suitable for cottages, caravans for weekend use or for lighting objects far from cities.

Water heating

Domestic hot water heating

Domestic hot water (DHW) in the boiler is heated during the sunshine thanks to electricity from a photovoltaic power plant. At the same time, the water can be reheated to a higher temperature by electricity from the grid, so that the required temperature is always guaranteed. This installation is suitable for households and businesses, with average and above-average DHW consumption, where an electric boiler is used for heating.

Comparison of returns

By installing a FVE plant, the consumption of electricity from the grid is reduced, thus achieving savings. The investment associated with the installation is gradually paying off thanks to savings. The return on investment is normally 10-13 years for FVE plants with and without accumulation and 6-8 years for FVE plants for water heating.

For comparison, we present here the return on other energy measures: heat pump 9-15 years, house insulation 12-18 years, recuperation 15-18 years

The investment in an island system is usually compared to bringing the connection to the point of consumption. The price of the connection is proportionally expensive distance of the place of consumption from the possible place of connection.

New green
savings

We will handle all documents and applications for obtaining a subsidy for the construction of a photovoltaic power plant (FVE) for your facility. Subsidies are provided to reduce the energy intensity of buildings. The installation of a PV plant reduces the consumption of electricity, ie the energy intensity of your building.

About us

History

We have been dealing with the installation of equipment that obtains energy from renewable sources since 2008. During the period of operation in the field, several hundred projects were implemented with installed outputs from 0.2 kWp to 5,000 kWp. The smallest of the installations supplies energy to the lighting of the public transport stop, the largest system can supply energy to a medium-sized production plant.

Eligibility

We are an active member of the non-governmental and non-profit professional association Guild of Applied Photovoltaic Technologies. We have a valid professional qualification Electrician of photovoltaic systems, without which it is not possible to install photovoltaic power plants and apply for subsidies.

Solution

New and more efficient technologies are constantly being developed, we keep up with current trends in the field. We bring tailor-made solutions for which we use the most suitable technological procedures. We use proven components from reputable manufacturers.

FVE 5,11 kWp

In May, the implementation of HFVE 5.11 kWp in Duchcov was completed, it was installed on a countertop roof with self-supporting construction with the possibility of accumulation in lithium batteries with a capacity of 7.7 kWh. HFVE was partially funded by the New Green Savings Program.

APRIL

2023

FVE 5,76 kWp

HFVE with a peak output of 5.76 kWp was installed in Krupka near Teplice. The power plant includes lithium batteries with a capacity of 9.6 kWh, the batteries are able to ensure the operation of the household in the event of a power failure even in bad weather. The HFVE was partially funded by the New Green Savings Program.

FVE 3,64 kWp

A photovoltaic power plant with a peak output of 3.64 kWp was installed in Proboštov near Teplice. The power plant includes lithium batteries with a capacity of 6.5 kWh, the batteries are able to ensure the operation of the household in the event of a power failure in bad weather for 1 day. The FVE plant was partly financed from the New Green Savings program.

Island system 265 W

In March 2021, we lit up a monument near Stadice. Batteries are used as a source of lighting, which are recharged every day with panels with an output of 265 W. We built the lighting of the memorial on the subject of the village of Řehlovice, with which we have long-term cooperation on cost-saving measures.

2018

Island system 11,13 kWp

In January 2018, we built another island FVE plant with an output of 11.13 kWp with accumulation in gel batteries with a capacity of 4 kWh. This system is used to power electrical appliances and lighting the social and technical equipment of the guard house at the tourist lookout in Jais Mountain at 1800 m above sea level. in the United Arab Emirates.

FVE 3,6 kWp Krupka

We completed a photovoltaic power plant with accumulation in batteries. For 100% energy use, we also installed a Wattrouter and a boiler for DHW heating. In the event of a power failure, the standard household operation for 1 day is ensured. FVE was partially financed from the subsidy program New Green Savings, we completely settled the subsidy for the investor. The payback of this system is 13 years, the expected service life is 25 years.

Island system 0,2 kWp

For greater comfort and safety of the inhabitants of the village in the north of Bohemia, we lit a public transport stop. The electricity distribution network is several hundred meters away. The variant of building a connection from the distribution network and the island system was compared. The variant of the island system was much more advantageous and therefore it was implemented.
