More revenue. With a BESS investment.

Unlock your solar park's true potential WITH ENERGY STORAGE!

Solar generation alone is no longer enough for maximum returns. If you trade on the free market, you already know: growing your solar park revenue depends on when the energy reaches the market, not just how many kWh you produce. A BESS paired with your solar park turns this difference into measurable profit.

Why invest in a BESS?

On the free market, timing decides your revenue. Not volume.

The problem

With the phase-out of the KÁT feed-in tariff system, solar park owners have entered a market environment where renewable generation and demand no longer line up. At midday, when most solar plants produce, the spot price is at its lowest, sometimes turning negative. In the evening, when demand exists, the park stands idle. This gap widens every year as more solar capacity joins the grid.

The solution

A BESS closes exactly this gap. It charges at the low point and discharges at the peak. Revenue depends not on the absolute price level but on the size of the spread, and over the past three years that spread has multiplied. Whoever builds storage capacity now enters the market with an ever-growing advantage. Whoever waits will enter under worse conditions, so it pays to install battery storage at your solar park as early as possible to operate it optimally and preserve the value of your investment long-term.

Why now?

Every year of delay extends your payback period.

⚠️
From January 1, 2027, energy storage prices will rise! China is gradually phasing out the battery export VAT rebate: reducing it from 9% to 6% in 2026, then eliminating it entirely from January 1, 2027. This leads to a +6% rise in manufacturer export costs, which is expected to be built into the sale price. Whoever purchases the system in 2026 can still buy at today's price.
What you lose by waiting
You lose significant revenue every single day.

Every day a solar park spends on the free market without a BESS, it sells at a lower capture rate. For a 1 MW park, this can mean up to EUR 130,000 in lost annual revenue, nearly EUR 350 per day. Operating efficiency directly affects payback — this is a calculable, not an estimated, loss.

The spread keeps growing, and slots keep filling up.

Manufacturer capacity is booked a quarter in advance. Whoever acts now will be in live operation by next season. Whoever waits will enter later, at a higher cost and with a longer wait.

Your competitors get ahead.

A power plant equipped with a BESS trades with a more flexible schedule, lower balancing energy costs, and a higher average price.

What you gain by acting now
+
Arbitrage revenue from the daily spread.

Up to EUR 70,000–109,000 in annual revenue per 1–1.3 MWh of capacity, based on the HUPX daily spread.

+
Sell at peak prices.

In the evening and morning, not forced into the midday price low. The BESS stores your production and discharges it where the price is highest.

+
2–4 year payback.

Why SOLARKIT?

A financially stable, experienced partner with a direct manufacturer channel.

A BESS project is not a simple hardware purchase. Technical design, DSO permitting, EMS integration, commissioning protocol, and manufacturer warranty coordination all run in parallel, and each one carries risk of error. SOLARKIT keeps all of this in one hand.

SOLARKIT Europe Kft. In the highest domestic credit rating category, according to Dun & Bradstreet

The project process

Five steps from your request to live operation.

No need to arrive with technical details in advance, we clarify everything during the consultation.

1

Initial assessment and offer

We request your park data and prepare 1–2 configuration options with CAPEX calculation and payback comparison.

2

Manufacturing and DSO documentation

BESS manufacturing and DSO permitting documentation run in parallel: SLD drawings, datasheets, EMS integration plans.

3

Site preparation

Online and phone consultation before the BESS and PCS arrive: foundation, trenching, cabling.

4

Installation

Based on the documentation, with your own or a recommended partner. We provide documentation and supervision.

5

Cold/hot commissioning and SAT

Manufacturer commissioning protocol, FAT validation, capacity test, SAT report. From this point, the system can be controlled remotely.

Manufacturer capacity

Manufacturer capacity is booked a quarter in advance.

Whoever acts now can be in live operation by next season. Whoever waits will enter under worse conditions.

Payback

How much revenue can a BESS generate?

Payback time depends on three factors: the size of the HUPX spread, utilization, and configuration. The figures below are scenarios based on a sensitivity analysis — an informational model, not a promise.

Configuration Capacity CAPEX range Typical annual revenue Payback range
4× Dyness DH200Y124.9 kW / 261 kWh cabinet 1,044 MWh 220–260k EUR 70–90k EUR/year 2.5–4 years
5× Dyness DH200Y99.9 kW / 261 kWh cabinet 1,305 MWh 260–300k EUR 85–109k EUR/year 2–3.5 years
