Blaustrom
A website for Blaustrom, a Bavarian company that sells solar power systems for homes: solar panels, batteries and EV charging stations.

Team
I was the only designer and worked with Blaustrom’s founder. Their developers built the site.

Main page
The site is one long page with five sections, one for each menu item. The first section opens on a dark screen with the logo, followed by a slider with three slides on the blue gradient.
First screen
The logo, the line “It’s all about energy” and a “Design System now!” button.
We make electricity blue
A solar system with a battery can cover up to 80% of a home’s electricity. Blaustrom supplies the rest from regional renewable sources.
Your energy future from a single source
A line drawing of a farm, solar panels, a wind turbine, a house and an electric car. Each plus button opens a short note about that part of the system.
From Registration to Z
The five steps Blaustrom takes care of: inquiry, planning, installation, registration and operation.

About us
The text explains how Blaustrom differs from a usual energy supplier. Customers produce most of their electricity with their own solar system, and Blaustrom delivers only small amounts of Bavarian electricity from the grid. Next to the text is the founder, Fabian Eckl, with a short bio and links to his profiles.

Product partners
A slider with the four brands Blaustrom installs: BYD batteries, SolaX inverters, LG solar modules and ABL charging stations. Each slide has three key points with icons, a short text, the brand logo, a link to the brand’s website, a datasheet download and a video.

Configurator
The configurator plans a system in four steps. Each step is its own screen, and the bar at the top shows which steps are done. The first screen asks for the address and whether the customer already has a solar system.


Step 1
Solar system
A satellite map of the house. Each roof area gets a letter and its own row with the size in kWp, the orientation and a slider for the roof angle from 0° to 50°. A roof area that should not be used can be switched off.

Step 2
Consumer group
Home, farm or business. For a home, a yellow slider with household sizes from one to six people sets the yearly electricity use. The number in kWh below it can also be typed in.

Step 3
Electricity supplier
The customer picks their current supplier from a list and sets what they pay per kWh on a slider from 15 to 35 cents.

Step 4
Your blaustrom system
Three systems to choose from. Each card shows the share of electricity the home would produce itself, the size of the solar system and the battery, the yearly production, and how much electricity would come from and go to the grid.
After step 4
Personal proposal
“Take it” opens a form with the chosen system on a blue panel. The customer leaves their name, email and phone and can subscribe to the newsletter.

After step 4
Thank you
The last screen has all four steps checked and says that a detailed proposal was sent by email.

Contact
A form with name, email, phone and message, and a Google map where the office is marked with the b from the logo. The dark footer has the address, social links and the line from the first screen, so the page ends the way it starts.

Responsive
Tablet and phone layouts
320px +
On smaller screens the menu folds into a round button in the top-left corner and opens over the page. Slides and text stack in one column. The configurator needs a screen at least 720px wide, so phones show a short message about that in its place.
