Does grid-tied solar work during a power outage?

A standard grid-tied inverter stops operating when the utility grid fails. Sunlight alone does not keep the business powered. Backup supply requires a hybrid system with suitable equipment and a designed connection arrangement.

Does a grid-tied solar plant need batteries?

A standard grid-tied configuration does not need batteries: solar energy is used as it is generated. The grid supplies loads when solar output is insufficient. Storage and backup require a separate system configuration.

How is the right capacity determined for a business?

We start with the load profile, operating hours and grid connection parameters. We then assess available space, shading and expected generation. A monthly electricity bill alone does not show exactly how much solar output the site will use directly.

What determines the cost of a grid-tied solar plant?

The budget depends on capacity, equipment, mounting, roof condition, cable routes and protection. It also includes metering, monitoring and commissioning. An estimate requires the site address, consumption data and connection information.

What happens to surplus solar energy?

Surplus handling depends on the approved connection, equipment and contractual arrangement. Export can be limited, or surplus sales can be assessed where the relevant conditions are met. Owning a grid-tied plant does not by itself establish export terms or green tariff eligibility.

Can storage or backup power be added later?

We assess upgrade options through an audit of the existing plant. The review covers inverters, controls, protection and the loads that need backup. It determines which equipment can stay and what needs to be added or replaced.

Grid-tied solar power plants for business

SPP + grid (optional - "green tariff" / surplus sales)

For businesses with daytime demand, on-site generation can reduce electricity purchases. A grid-tied solar power plant operates alongside the utility grid, without batteries in its standard configuration. We size the plant around the load profile and site conditions.

ONG Solar designs, installs and services grid-tied systems for businesses in Ukraine from 30 kW. A standard grid-tied plant stops when grid power is lost. Backup supply requires a separately designed system.

Grid-tied solar power plant diagram

Solar panels supply site loads through a grid-tied inverter. The utility grid covers any shortfall. Surplus handling, metering and protection are defined during project design.

How we size grid-tied solar for your demand

We compare hourly business demand with forecast solar output. Installation and connection conditions help determine a suitable system size and project budget.

Load profile

We review daytime and night-time demand, including working days and weekends. This helps estimate how much solar generation the business can use as it is produced.

Roof or ground area

We check available space, shading, orientation and installation conditions. The generation forecast accounts for the site location and seasonal changes.

Connection and surplus

We assess grid parameters, metering and the permitted export arrangement. Export limitation can be included when needed. Surplus sales are considered separately under the applicable connection and contract terms.

Cost and payback

The assessment includes equipment, installation, service and the cost of purchased electricity. Estimated savings depend on solar energy used on site and the agreed approach to surplus generation.
