For fifty years, wind powered nations. We decided it should power homes.
TESUP is the global leader in household wind energy. We build 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. This is what stands behind that.

A decade as a company. Half a century of engineering.
TESUP was established in London in 2016. Ten years of designing, building and standing behind household wind.
The company is ten years old. 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 the thing 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.
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. The wind does not keep the same hours. Build only one half and you have built half a day's power. We build the day.
Semi-flexible. Bonds to a curve, carries no frame, weighs a fraction of glass. The surfaces glass was never going to reach.
A conventional panel is silicon under glass in an aluminium frame. Heavy. Rigid. Impossible on a curved roof or a structure that will not carry the load. Our semi-flexible panels put the cells on a polymer backing instead. They follow the shape of what they are fixed to. Van roofs. Boat decks. Cabin tops. Buildings that were never designed to hold a solar rack — and now can.
Anyone can sell you a machine. Only a company that builds both halves can tell you which one you actually need.
Thirty-four countries. Twenty-three languages. One standard.
Every country with its own storefront. Drawn from our own store configuration — check it against the store switcher above.
38 retail storefronts. 34 countries. A rest-of-world store for everywhere else. 23 languages. Each one 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.
Cut stock, racked and waiting. Which is why a blade set leaves here in days, not weeks.
And the part most companies leave out
Leading a market is not the same as selling to everyone in it. So we will 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 ten.
Fifty years of engineering. 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. The laser and warehouse photographs are ours, taken in our own building. The photograph of the van roof is a licensed stock image, not our own. 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.
