Type of Solar Station

Solar power is divided into the following types:

Connected to the Grid (On-Grid), the simplest and most cost-effective

A simple grid solar power plant is usually the best financial option. Network systems provide the best return on investment because of their low cost and simple system design. If the facility is connected to the central power grid, then the solar grid generates electricity both for its own needs during the daytime and by pumping surplus into the central grid when consumption is low. Excess electrical energy is usually sold to power grids. If special higher rates are used for solar electricity, there are 2 meters - one for generation, the other for consumption. All electricity generated is sold at a higher rate to the grid, and the house’s electricity needs are met by purchasing electricity from the grid at the normal price. In this way, not only can zero annual electricity costs be achieved, but also zero annual electricity consumption (in summer, excess energy is supplied to the grid, and in winter and at night, when the sun is not enough, the house is powered mainly by the central network).

Stand-alone (Off-Grid), more complex systems with a large set of equipment

An off-grid solar power plant is probably the least practical for ordinary homeowners who have access to a central grid, but it’s great for remote areas where there is no electricity and can be the best choice for your mountain house, holiday or mountain hotel. When it is not possible to connect to a central power grid, a solar power plant converts light into electricity for electricity, lighting, household appliances, water pump or hand tool, etc. Usually, batteries of various types are used for energy storage, and as a backup energy source is used liquid-fuel electric generator. The whole system provides an autonomous power supply to the facility without the need to connect to the central network. The facility remains completely independent of tariffs, surges and accidents.

Hybrid systems (Hybrid), more complex systems and most flexible

In some cases, a hybrid solar power plant may be most useful, especially if there are regular power outages in your region. If you really value energy independence and maximum use of renewable energy in your home, a hybrid solar power plant is the best solution for saving consumption and providing your facility with a backup power supply due to the energy storage system. Photovoltaic systems are connected to poor quality Grid. In the event of a power outage or insufficient power supply, a solar power plant with backup power is used to cover the peak load. In this case, batteries or, in the case of large capacity, another source, such as a diesel or petrol generator, are used. In this hybrid system, solar energy significantly reduces consumption from other energy sources and during power outages. While there is electricity in the network, the system works as a network connected to the Grid.


The best way to choose a suitable solar system is to contact your nearest design and installation companies. Local solar panel installers will best understand which solar system is best installed in your region and how you can maximize your investment in a solar power plant
