The presented solution can be fun
electricity tariffs for legal entities;
part of the money spent to pay for the electricity companies;
consumes electricity during daylight hours.
Business owners are faced with
the problem of constant growth of tariffs for legal entities.
Economic Development and Trade forecasted cost of electricity
energy for commercial customers and according to their estimates, the price will rise
annually by 10% in 2019-2021, respectively. This will spur business representatives to
implementation of complex energy efficiency measures. Already since 2011, and
ending with the year 2019 the price per kWh of electricity increased by 3.5 times. If
this trend continues, by 2020, the cost of 1 kWh will be
about 5 UAH.
January 1, 2019 increased the price of electricity for businesses.
electricity will rise further to the level of European prices.
electricity for legal persons as of 2019 is set to
the level of 3.08 UAH. per kWh.
prices for enterprises in Ukraine depends on the service provider, and whether there are between them
intermediaries. So the price can vary between 3 UAH. and even higher.
Reduce daytime power consumption
the enterprise at the expense of solar power, working to fill
own consumption (without the “green” tariff).
The easiest way out – to set the network station to replace their own consumption. The advantage of such a station is
that it does not use batteries and there is no red tape, which can stretch up to a year, as is the case with stations under the “green” tariff. Compared to the station of “green” tariff for such a station requires less financial investment in the development of design documentation, and may increase the submarine power grid. You buy a station of the power that you need, and install it by introducing into the existing infrastructure. You only need the availability of suitable premises for the desired number of solar panels.
station reduces the annual consumption of 30-50%, provided that the main
electricity consumption now accounts for the daytime,
when the sun is shining and solar panels generate energy. It can be

power for their own consumption works without batteries
in real time. Connection to the “green” tariff is not required, but in the long term
such a possibility is also not excluded. Generated solar station
Electricity is immediately consumed by the load, eliminating the consumption of the network and
covering their own consumption. When solar energy is not enough, the difference
automatically taken from the network. When solar power in excess, for

Inverters are required to convert the direct current solar
panels to alternating current with the same parameters as in the current network.

part of which is missing.
In the first case, the load

consumption is equal to the performance of the solar power plant (SPP)
electricity consumption from the grid is zero. Therefore, at the stage of designing SES
it is important to conduct a thorough analysis of energy consumption, to design
balanced system that will eliminate the situation where it is necessary
restrict the generation of electricity from solar panels. But there are situations
when the electrical work must be stopped for service
events, or weekends and holidays, but in this case works
using the on-line monitoring, you have the opportunity to observe in real time
actual energy consumption, optimizing peak
load and use solar energy as efficiently as possible.
sunny days, the station will be able to provide your business with 95-100% energy
generated from the sun. The rest of the substitution on the solar station will
up to 50% of daily consumption.

Electricity here is 3.1 UAH. For the year, the company consumes 149,000

to the conclusion that the best solution is to install a solar power plant

implementation of the project. this power station produces annually about 91930
