For fifty years, wind powered nations. We decided it should power homes.
TESUP is the global leader in household wind energy. Almost a decade of building household wind turbines and semi-flexible solar panels — both halves of a working system, engineered by one company, for one roof, one battery, one family. Thirty-four countries. Twenty-three languages. One standard.
Almost a decade in business. Half a century of engineering.
TESUP began active business in London in 2018. Almost a decade of designing, building and standing behind household wind.
The company is young. The engineering is not. Our expertise runs back to 1974 — through hydroelectric, wind and solar power plants totalling more than 1,000 MW of installed capacity. Utility scale. National scale.
That is what almost nobody else in this market has. Most competitors began with a small turbine and worked outward. We spent fifty years building the large ones, then brought that discipline down to something that fits on a roof. The scale changed. The standards did not.
Two halves. One system.
Almost every company in small-scale renewables makes one thing. Wind companies make turbines, then point at somebody else's panel. Panel companies make panels and have never machined a blade. Two industries, one customer, nothing shared.

One roof. A turbine and panels, working the same battery.
We make both. Household wind turbines and semi-flexible solar panels. One company. One system. One battery that does not care which machine filled it, only that something did.
The sun sets every day, everywhere, without exception. The wind keeps different hours entirely. Build only one half and you have built half a day. We build the day.
Anyone can sell you a machine. Only a company that builds both halves can tell you which one you actually need.

The other half. Semi-flexible — it bends to the surface, carries no frame, and weighs a fraction of glass.
Thirty-four countries. Twenty-three languages.
38 retail storefronts. 34 countries. A rest-of-world store for everywhere else. 23 languages. Each with its own currency, its own tax treatment, its own shipping, its own terms. Every one mirrored again for wholesale — 76 storefronts held in step.

Global is not a word you earn by shipping abroad. It is what happens when a customer in Osaka, in Rio, in Riyadh and in Trégunc each open a page written for them, priced for them, in their own language — and none of them can tell which one we built first.
Cut in-house. Down to the millimetre.
Blade sets are laser-cut in our own building, from 1.2 mm high-strength aluminium, on our own fibre laser. Three profiles from the same stock on the same bed: 2–20 m/s for 2 kW peak. 4–25 m/s for 3.8 kW. A six-blade set at 5–35 m/s for 4.5 kW, built for exposed coastal sites.
Owning the machine means owning the shape. A subcontracted blade is a purchase order and a six-week conversation. A blade on our own bed is a file, a test cut, an afternoon. That is the difference between a company that assembles turbines and a company that designs them. Manufacturing runs mainly in Slovakia and London, and in Turkey as well.
And the part most companies leave out
Leading a market is not the same as selling to everyone in it. So we keep saying the things a smaller company cannot afford to say.
If your roof sits deep in a dense old city, walled in on four sides, do not buy a turbine from us. Buy the panel. If you are inland with no real wind, measure first, then decide. If you have a strong flat roof that will carry the weight, buy rigid glass instead of semi-flexible — for that job it is the better panel.
We can say all of it because we build both halves. When the honest answer is “not the turbine,” we still have the one that works. A customer told the truth in year one is the reason there is a year eight.
Fifty years of engineering. Almost a decade of building. Thirty-four countries. Both halves of the system.
That is what global leader is supposed to mean.
The founding year, the 1974 engineering lineage and the 1,000 MW installed-capacity figure are our own published company record. Every photograph on this page is our own, of our own products. The map is drawn by us from our own store configuration, and the storefront, country and language counts can be checked against the store switcher on this site. The turbine figures are our own published specifications and are checkable on the product page.
