Frequently asked questions

A grid-tied plant operates only during the day and only when there is voltage in the grid — it feeds excess energy into the grid, but shuts off during an outage. A hybrid plant has a battery: it stores energy during the day and powers the site in the evening and during outages.

Only if the plant has a battery (hybrid or with a battery energy storage system, BESS) or a generator. Standard grid-tied panels automatically shut off during an outage — this is a safety requirement. If you need autonomy, we design in a battery from the start.

It depends on the capacity, type of site and your consumption. We calculate this for your specific site as part of a commercial proposal: capacity, approximate turnkey cost, savings and payback period. For an estimate, your average electricity bill is enough.

Start by identifying critical loads: what exactly must not stop. Next, we select backup power — an ATS (AVR) cabinet (automatic switching to a second input or a generator), a generator, or batteries (BESS). We'll advise on what's cheaper and more reliable for your specific task.

A generator is cheaper upfront but requires fuel, maintenance and is noisy; it switches on with a delay. A BESS switches instantly and operates quietly, but is more expensive and limited in operating time. They are often combined. We'll select the right scenario for your site.

The entire cycle handled by one company: site survey, design, equipment (including our own manufacturing), installation, commissioning, documentation and handover into operation. You get a single contractor and a single contract — with no gaps between stages.

The procedure is: obtaining technical conditions from the regional grid operator → design → construction of the line and transformer substation → commissioning → putting into operation. We take care of the design and construction. Timelines depend on the capacity and connection conditions.

The price consists of the connection fee (based on current NKREKP rates, depending on capacity and voltage level) and the cost of the facilities themselves: the line and the substation. We'll calculate an approximate amount for your case; for a non-standard connection, we price it as an EPC project.

A KTP steps down the grid voltage (6, 10 or 35 kV) to the working 0.4 kV that powers your equipment. It's needed when you're connecting a high-power site to medium voltage — without it, connecting a large production facility to the grid is impossible.

Motors, pumps and transformers consume reactive energy, for which the supplier charges an extra fee. Installing a compensation unit (UKM) generates reactive power on site — the extra charge for reactive power disappears or decreases, and the grid is unloaded. It pays back quickly at sites with motors.

It works during the day in winter, but less — due to the shorter daylight hours and lower sun angle. At night, panels don't generate power. Round-the-clock power supply requires a battery or the grid; this is designed into the project depending on your task.

Options include: a hybrid solar power plant with a battery, a generator, or a battery energy storage system (BESS). For remote boreholes without grid access, we build a standalone package. We select the solution based on the pump's flow rate and your watering/water supply schedule.
