From the equator, for the world
Aphelia builds small-scale solar power satellites in geostationary orbit that beam firm, 24/7 clean power to the ground. Engineered in Malaysia — on the equator, directly beneath the orbit we use.
“Every other place on Earth has to look sideways to see the geostationary belt. Malaysia looks almost straight up.”
Aphelia · Kuala Lumpur, 3°N
Chapter I · Why Malaysia
Geostationary satellites sit directly above the equator. Malaysia sits almost directly beneath them — the shortest, steepest path from orbit to ground, over an arc far less crowded than those above North America, Europe and East Asia.
Equatorial advantage
ITU orbital slots are first-come, first-served, and filings rose ~400% in 2020–2025. Equatorial states have argued for preferential GEO access since the 1976 Bogotá Declaration. Early Malaysia-flagged filings are a strategic asset in their own right.
A live demand shock
The Johor–Singapore SEZ took Johor's data-centre capacity from ~10 MW in 2021 to ~1.3 GW in 2024. Most hyperscaler tenants carry 100% renewable mandates — stricter than the national target, and needing firm power.
Policy already in motion
The National Space Policy 2030, the Malaysia Space Exploration 2030 plan, the Malaysian Space Board Act 2022 and MASIC together target 1% of GDP and 5,000 jobs from space by 2030.
Neutral by design
A Malaysian supplier, from a country with a long non-aligned tradition, for the many buyers that want energy security without depending on a single geopolitical bloc's technology.
Chapter II · The constraint
AI data centres are expected to more than double their electricity use by 2030. On the ground, solar is bound by night, weather and the angle of the sun — it needs batteries to be firm and vast land to be large. Nuclear is firm, but takes 12–15 years to permit and build.
In geostationary orbit, 35,786 km up, a solar array sees the Sun more than 99% of the time — the only gaps are brief eclipses around the equinoxes. No night. No clouds. And the satellite hangs fixed over a single receiving site, so the beam never has to hand over.

National Energy Transition Roadmap (NETR)
Generation over 24 hours
Same sun. Very different day.
Shape only, normalised to peak. Ground curve is a clear-sky day; cloud and monsoon cut it further. Aphelia's 99% capacity factor is a design target in geostationary orbit, where eclipses are limited to short periods around the equinoxes.
Chapter III · The Aphelia SubTile
Every satellite is built from one repeated 500 mm SubTile. It collects sunlight on its back, converts it to microwaves on our own GaN chips, and radiates it through helical elements on its front. Scroll to take it apart.
Same part from the first test to the full constellation. Manufacturing scales incrementally, with no redesign at any step.
Chapter IV · Wireless power transmission
The phased array steers its beam electronically — the travelling colour across the transmitter is the phase gradient doing it. The link runs at 19.7 GHz through clear skies and light rain. When heavy tropical rain arrives over the receiving station, it switches to 12.2 GHz to hold power. Make it rain.
Atmospheric efficiencies are Aphelia link-budget figures for Malaysian conditions. Locked at 19.7 GHz, heavy rain would cut the link to ~4%; switching to 12.2 GHz holds a 43.65% floor. Visual is illustrative and not to scale.
The energy chain — what we build in-house
Why helical elements
−75%
GaN dies needed per tile versus patch antennas, with double the effective range. Helices are circularly polarised by nature, which rides through ionospheric scintillation better than linear polarisation.
Why a tapered beam
5 zones
Transmit power is tapered across five zones of the array to shape a near-Gaussian beam — concentrating energy on the receiving station instead of spilling it around.
Why GEO
35 yrs
Target life, versus 10–20 years typical in low orbit. Near-continuous sunlight removes the battery system, and the array radiates its own heat — eliminating ~2,000 kg of deployable radiators.
Chapter V · The satellite
A rigid, planar array of identical tiles folds around the bus for launch and opens in two axes in orbit. Two steerable auxiliary arrays track the Sun while the main array holds its aim on the receiving station.
Stowed for launch
Chapter VI · Against the alternatives
For the next few years, Aphelia's real competition for Malaysian and ASEAN power contracts is on the ground: solar farms with batteries, and small modular reactors. Here is how a satellite fleet compares — including what the first unit costs before scale.
Capacity factor
Levelised cost of energy, US$/kWh — the learning curve
| Johor 2035 fit | Solar PV + BESS | Nuclear SMR | Aphelia SBSP |
|---|---|---|---|
| Land footprint | ~10,000 acres | 1,500–3,000 acres | ~800 acres~90% less than a solar farm |
| Initial CAPEX | — | ~US$100M | ~US$35M~65% below SMR |
| Battery storage | 5.12 GWh, replaced every 10–12 yrs | None | None |
| Cooling water | Minimal | 378–606 MLD | Zero |
| Lead time | 5–7 years | 12–15 years | 3–5 years, phased |
| Treaty & licensing | Low | Very high (NPT, IAEA) | Moderate (ITU filing) |
| Scaling | More land, more batteries | New reactor build | Launch more of the same satellite |

Chapter VII · Markets
Firm renewable baseload for Johor's data-centre corridor, island grids and the national utility — sold under 20-year-plus power purchase agreements.
The Philippines and Indonesia share the Tioman economics at far larger scale: off-grid islands, typhoon exposure that limits ground solar, and expensive cable links.
Energy-security buyers in the Gulf, plus institutional partnerships in Japan and Europe — governments diversifying away from imported fuel and single-bloc technology.

Chapter VIII · The field
Beaming power is not experimental physics, and continuous GEO-to-Earth radio transmission has run over this region for decades. Space solar has stalled on two problems: satellites too large to launch affordably, and links too inefficient to pay off. A small, efficient, mass-produced tile goes after both.
Peter Glaser publishes the solar power satellite concept in Science.
NASA JPL / Raytheon beam 30+ kW over 1.6 km at Goldstone; rectennas convert over 82% to DC.
MEASAT begins continuous GEO-to-Earth transmission over Malaysia — the same path, carrying signal instead of power.
ESA SOLARIS cost–benefit studies find a positive business case for space solar in Europe.
Caltech MAPLE performs the first wireless power transfer in space, and beams detectable power to Earth.
DARPA POWER sets a power-beaming record: 800+ W over 8.6 km.
Venture capital arrives. Star Catcher, Aetherflux and Reflect Orbital raise more than $175M between them.
