SolarKube

Smart, affordable solar energy.

Solar power that fits your day.

SolarKube provides high-quality solar solutions for homes and businesses. We design smart installations carefully matched to your actual energy use — day and night — rather than offering standard packages.We also make a conscious effort to keep solar power affordable, so reliable, self-generated energy is within reach for more people.

Well designed. Honestly calculated. Ready for day and night.

Where we begin

An installation starts with the rhythm of your life, before any panels go on the roof.

Bonaire has abundant sunshine. The key question is therefore not how many panels we can install, but how much energy you need, when you use it and how much certainty you want.

We start with your actual use: during the day and at night, what needs to run at the same time, the changes you expect and the reserve that feels comfortable.

From that picture, we bring the panels, inverter, battery and any support from WEB or a generator together in one understandable design. Not a standard package, but clear choices and assumptions suited to your situation.

We do not design a collection of separate devices.We create one coherent energy system around your property, your use and your daily routine.
Designing a solar energy installation for a home in Bonaire

How it works

One system that moves with you throughout the day.

An installation supplies the electricity you need from the most logical energy source for as long as it is available. During the day, energy therefore comes directly from the solar panels whenever possible. If battery storage is present, it is charged from the panels at the same time. If the home or business needs more than the solar panels and batteries can supply, WEB or a generator covers the shortfall.

From morning to night

Fully automatic.

There is nothing for you to switch manually. The available sources and the order in which they are used are defined as part of the design.

During daylight hoursUse directly and charge the battery

The panels supply the home or business while charging the battery at the same time.

After sunsetThe battery supplies energy for later

The stored solar energy supplies the property for as long as the configured battery reserve allows.

When neededWEB or a generator supplements

The supplementary source automatically covers the shortfall when the solar panels and battery cannot supply enough.

Which system fits?

Your goal determines the technology.

There is no universal solar solution. The right setup depends on whether WEB is available, your daily consumption, the backup you want and how much energy you need outside daylight hours.

For most homes01

Hybrid

Solar panels, battery and WEB work together automatically through one inverter. The system is designed around your full daily energy needs.

  • Use solar power directly during the day while charging the battery
  • Use stored solar energy in the evening and at night
  • WEB automatically covers any shortfall
  • Add panels or battery capacity later
Without a grid connection02

Off-grid

An off-grid installation operates independently, without WEB as a safety net. It is designed for daily demand as well as less sunny days.

  • More solar panel capacity and a larger battery reserve
  • Designed for autonomy and peak power demand
  • Extra capacity for periods with less sunshine
  • Generator integration for additional backup
Mainly active during the day03

Grid-tied

A system without a battery can make sense for a school or business with high, predictable consumption during daylight hours.

  • Use generated energy directly during daylight hours
  • No storage for evening or nighttime use
  • During a WEB outage, the system cannot supply solar power and shuts down safely
  • Usually not the best starting point for homes
  • Exporting electricity earns little on Bonaire

Indicative calculations

Two systems. Complete and concrete.

These examples provide clear price guidance and show what is included.The system price, generation and savings are indicative; the final outcome follows only after we assess your consumption, property and installation location.

IndicativeBut never vague

WEB’s fixed connection charges remain payable. Roof, shade, cable route, electrical panel, timing of consumption and battery reserve determine the final price and saving. After the assessment, you therefore receive the assumptions used and a personal range.

From the first conversation to a system you understand.

From your needs to installation

Understand. Calculate. Design. Build.

  1. Step 1

    We examine your actual use

    Your electricity bill is the starting point. Your daily routine completes the picture, including changes you expect after installation, such as using air conditioning more often or for longer.

  2. Step 2

    We assess the location

    We carefully assess the roof, shade, electrical panel, existing equipment and required cable routes in advance.

  3. Step 3

    You receive a substantiated, transparent proposal

    You receive a complete price, the consumption data and assumptions used, and the expected range. We also specify the make, model and capacity of the main components and what is included in the installation.

  4. Step 4

    We install, test and hand over with care

    We configure protection, bypass, backup and monitoring. During handover, we explain how you can track generation, consumption, battery status and WEB usage yourself.

Every step remains verifiable: you know what the design is based on, what will be installed and how the system performs after handover.

After installation, too

A system that grows with you

Has your consumption changed, are you adding an electric car, or would you like more reserve for the night? A well-designed installation does not need to start from scratch.

Initial estimate

Tell us your goal, and we will show you what is possible

Perhaps you want to reduce your WEB bill as much as possible as energy prices rise, become fully self-sufficient, expand your existing installation or include solar power in a new-build project?Tell us about your situation and what you would like to achieve. We can quickly give you a clear and surprisingly useful first assessment — with no obligation.
