Choosing the type of solar station depends on your needs. 

• If you are looking for energy independence in your home, saving money or replacing part of the electricity, a hybrid solar power plant is right for you. 

• Your need for energy independence from the grid and rolling blackouts? Then you should select an autonomous station. 

• In order to sell electricity to the network at a feed-in tariff or Net-billing, as a rule, a network one is installed, because this is the cheapest type of SPP.

Primary requirements: 

• the building must be privately owned and commissioned;

• enough space on the roof or ground. 

There are network, hybrid and autonomous SES. Each of them is suitable for a private home. The choice of the type of solar power plant depends on the needs of its owners. 

The payback of any solar station, first of all, depends on electricity tariffs. With current tariffs for households at the level of 1.6 UAH/kWh. payback is more than 10 years. But you need to understand 2 aspects:

• the cost of electricity for households does not correspond to the market value and is subsidized by the state. Sooner or later (rather sooner) the tariffs will be brought to the market level, which means that the payback of the station will immediately become 4-5 years.

• solar station is an additional level of comfort and energy independence of a private house

We recommend our customers an annual review of the plant by PV engineers. Station diagnostics can be remote, but it is much more efficient to inspect the station directly on site. We offer our customers a package service contract, which includes comprehensive supervision of the operation of all elements of the station. Service package includes: 

• Maintenance of the station with a site visit 1-2 times a year;

• Remote monitoring;

• Technical support of the object – technical consultations, remote configuration or change of system parameters.

The service life of photovoltaic modules is 20-25 years. 

As a rule, the power of the solar power plant is selected in such a way as to completely replace the consumption of the facility in the summer.

To calculate the required power of photomodules, you need to divide the daily electricity consumption in the summer (the number of kWh) by 5 – this will be the power of the solar power plant (for example, with an average daily consumption of 10 kWh, you need a solar power plant with a capacity of 2 kW).

In a broader sense, the power of the solar power plant is selected so as to replace the power consumption of the facility during the required period of the year. And since in different periods of the year the performance of the solar power plant changes (more in summer, less in winter), the required power of the station will also change.
Daily productivity of 1 kW photomodules in different periods of the year on the territory of Ukraine:

• 1 kW for a summer day will give: 5 kWh of electrical energy
• 1 kW for a winter day will give: 1 kWh of electrical energy
• 1 kW for autumn/spring will give: 3 kWh of electrical energy

Accordingly, even with the same consumption of 10 kWh per day throughout the year, the required capacity of the SPP for replacement in different periods of the year will differ (from 2 to 10 kW), and this depends on the specific wishes of the customer.
