Solar Power Plant for a House or Cottage

A solar power plant for a private house does two things. First: during the day the house runs on its own energy — the electricity bill goes down. Second, if you add a battery: the house has power even during outages. LK Energy (Odesa) designs and installs home power plants, roughly from 5 to 30 kW, turnkey — from the site visit to grid connection and paperwork.

The main choice: with a battery or without

Grid-tied plant (without a battery)

Cheaper. Reduces the bill through daytime solar consumption. An important honest point: when the grid goes down, this type of plant shuts off and provides no power — this is a grid safety requirement.

Hybrid plant (with a battery)

More expensive, but does both things: reduces the bill and keeps the power on during outages — the refrigerator, boiler, internet and lighting run off the battery.

Not sure which to choose? We'll calculate both options — you compare the numbers and decide.

How the plant reduces your bill

During the day the house consumes energy from its own roof instead of the grid. If the plant generates more than the house consumes, new plants are covered by the Net Billing mechanism: the surplus is sold to the grid at market prices and reduces the final bill. This is a nice bonus, not guaranteed income — the main savings still come from your own consumption.

Generation is lower in winter and higher in summer — that's why we calculate the annual balance: we look at your bills for 12 months and show what share of your annual consumption the plant will cover on your specific roof. In winter, the grid makes up the difference — the house is never left without power.

How the installation process works

We visit the site → assess the roof (pitched or flat, or a plot near the house) and consumption → calculate the capacity and cost estimate → design → installation → connection. We handle the paperwork for connecting the plant to the grid ourselves. The timeline depends on the roof and capacity — we'll state it together with the cost estimate.

Why LK Energy

We're not just "a crew with panels": LK Energy is a manufacturer of electrical switchgear equipment with its own factory in Odesa (in production since 2015) and a full-cycle contractor operating since 2005. We manufacture the switchgear and protective automation for your plant ourselves. Among our completed projects are about 100 solar power plants of various scales — from private rooftops to an industrial 4.95 MW plant.
