How to choose a solar power plant for your home?

Are you thinking about building a solar power plant for your home? Below are the main criteria to pay attention to: Main criteria:

Purpose of solar power plant. What is the purpose: use as a main or additional source of power supply, or sale at a “green” tariff.
Energy consumption that the station must fully or partially cover.
The size of the area for placing the station.
Installation location - on the roof or on the ground. Accordingly, the method of mounting solar panels: ground-based structures or a roof mounting system.

Requirements for installing a solar power plant:

Installation angle and direction of solar panels.
When installing a grid-tied or hybrid power plant, you must ensure that the allocated power to the household matches the desired power of the plant. This information is specified in the “Electricity Use Agreement” between the supplier and the consumer. The permitted maximum power for individuals is 30 kW.
Carefully study all available information on the main equipment.
Geographical coordinates of the station installation, since different regions of the country have different output. For example, Odessa is a favorable region.

The government's tariff policy on the energy market is changing rapidly

Types of solar power plants

Depending on the purpose, solar power plants for the home are divided into three types:

autonomous
network
hybrid

Autonomous solar power plants

They are used as both the main source of electricity and as a backup or uninterruptible power source.

Composition of an autonomous solar power plant:

Photovoltaic modules.
Autonomous inverter.
Batteries.
Charge controller.
DC and AC protection kit.
Fixing kit or support structures.
Cable and wire products and consumables.

The principle of operation of an autonomous solar power plant

Autonomous solar power plants are most often used in places where there are no electrical networks, since laying cable lines is difficult, impossible or economically unprofitable.
Stations of this type do not support parallel operation with a centralized power grid.
However, they have the ability to work as a UPS, as well as with diesel and gasoline generators.
Modules convert solar energy arriving at the surface into direct current.
They charge the batteries and simultaneously power the load connected through an inverter or controller.
The inverter, in turn, converts direct current (DC) received from solar panels into alternating current (AC).
When solar modules cannot provide energy to the consumer, batteries become the main source of electricity.
The charge controller controls the battery charging process.

On-grid solar power plants

Power plants transmit electrical energy to the grid to save consumption and sell excess generated energy at a feed-in tariff.

Composition of a network solar power station:

Photovoltaic modules
Grid inverter.
Bidirectional meter with GSM module.
DC and AC protection kit.
Fixing kit or support structures.
Cable and wire products and consumables.

The principle of operation of network power plants

The principle of operation of network power plants has some differences from the operation of autonomous ones. Photovoltaic modules convert solar energy arriving at the surface into direct electric current.
The network inverter, in turn, converts direct current (DC) received from solar panels into alternating current (AC) and transmits it to the electrical network.
If the power of the station exceeds the subscriber’s consumption, then a “reverse flow” of energy is created into the external network.
The amount of energy consumed and transmitted is recorded by a special bidirectional counter.
At the moment when the solar power plant does not produce electricity, all the necessary electricity for the home is consumed from the network.

Hybrid solar power plants

Hybrid stations combine the advantages of networked and autonomous ones. The operating logic of a hybrid inverter may be different, depending on the settings.

Composition of the hybrid power plant:

Photovoltaic modules
Hybrid inverter.
Batteries.
Charge controller.
DC Protection Kit.
AC protection kit.
Fixing kit or support structures.
Cable and wire products and consumables.

Advantages of solar power plants

Energy independence. Uninterrupted power supply
Passive income. Possibility to sell electricity to the state at a feed-in tariff.
Reducing electrical energy costs.
Environmentally friendly. The solar power plant is absolutely harmless to the environment.
Long service life. The service life of solar panels and inverter is from 25 years.
With proper installation and operation, the system does not require large maintenance costs.
Long warranty for main equipment. Depending on the manufacturer, the warranty for monocrystalline solar panels and polycrystalline solar panels is from 10 years, for inverters - from 5 years.

The stations allow not only to provide the house with an autonomous power supply, uninterrupted power supply, but also to sell electrical energy at green tariff.
