An energy-efficient home, independent of fossil-fuel energy sources
The house stops being an expense, cutting its dependence on electricity suppliers by up to 100%.
Estimated at 1,400 kWh per 1 kW a year and 0.35 kg CO₂ per 1 kWh. Exact figures follow the roof survey.
A system with a battery is a house that runs on the sun by day and puts the surplus into the battery, then spends what it stored in the evening. The grid is still there, but it is rarely needed: even when it goes down, nobody in the house notices. Take a look at how it works.
The film runs 2 minutes 23 seconds, with sound: a full day of the system, from night to night — sunrise, noon, a passing cloud, the grid switched off and an evening on stored power. The narration is in Russian, with English subtitles.
We do not use off-the-shelf solutions.
The parameters of the system are matched to the particular house: what the roof allows, the demand, the location, the consumption profile.
Once the system is running, we go through its performance charts and suggest further optimisation — so that the roof area, the panels chosen and the battery storage deliver as much as they can.

We get our panels, inverters and battery storage from the manufacturing plants themselves, not from resellers’ warehouses. The model and the specifications are known before anything is signed: the datasheets are in the section above, and you can check them yourself. The equipment meets IEC 61215, IEC 61730 and IEC/EN 62109.
Four years of direct contact with the factory’s engineers: technical questions are settled directly, not through a distributor. Spare parts travel by express delivery — in our own experience a replacement inverter module arrived in a week.
A university degree in engineering: radio engineering, Soviet-era training. The system is worked out from the loads and the physics of the property: the calculation comes first, the choice of equipment after.
The manufacturer releases new versions roughly every six months. We update the inverter firmware and the battery management system as they come out, at no separate charge.
The first year of servicing and round-the-clock support are included in the project price — there is nothing extra to pay for them.
Our own photographs from completed projects. Hover over a card or tap it to open the shot.
Panels on raised mounts at the calculated angle. A walkway is left between the rows for servicing and water run-off.
Rails on concrete weights, the roof covering is not drilled.
A Deye inverter, a separate protection board and cable runs in conduit.
Tell us about the property. We will calculate the output and match the system configuration to what you need.
