Solar energy and quiet Bitcoin mining in Cyprus

Turn Cyprus sunshine into power for your home — and Bitcoin from what you do not use

Helios Mining designs solar and battery systems in Limassol, then uses only the leftover daytime energy to run quiet Bitcoin miners. You keep the power. You stop giving cheap export away. You can see the hardware before you buy.

Helios Mining Cyprus is the solar and surplus-energy arm of Heliosmac Solar Enterprises Ltd in Limassol. We design hybrid and off-grid solar with LiFePO4 batteries. Where the electrics allow, unused midday solar runs quiet Bitcoin miners instead of being exported under 2026 net billing. Licensed installation is by Limassol Electrician 24/7. Visit the showroom by appointment at Kosta Partasidi 38, Shop 14, Limassol. WhatsApp +357 94449354. Solar and storage come first. Mining is only the leftover load.

What Helios Mining does

We build electrical systems that use Cypriot sunshine on your own site. A typical project is solar panels, a hybrid or off-grid inverter, and LiFePO4 battery storage. The house, farm or workshop is served first. Hot water and an EV charger come next. If midday sun is still going spare, we can add quiet Bitcoin miners as a planned load.

Who this is for

• Homeowners who have, or want, hybrid or off-grid solar and do not want to sell surplus power at a low export rate
• Villa and farm owners who want real backup, not only a grid-tied array
• Sites that already dump midday solar into net billing
• Anyone who wants to see the panels, batteries and miners in Limassol before they decide

Owner-occupied homes and private land only.

What we install

• Home hybrid and off-grid solar, typically 5 kW to 10 kW, with 15 kWh, 30 kWh or 45 kWh LiFePO4 storage
• Larger 3-phase systems, 20 kW to 100 kW, for land, pumps, workshops and commercial roofs
• Board upgrades, 30 mA RCBO protection, surge protection and TT earthing
• Quiet home miners, and on larger sites higher-hash machines sized only to spare solar
• An optional place in a local solo/hybrid Bitcoin mining pool, capped at 21 members — the pool is not the product

Why surplus mining exists under net billing

From 1 January 2026, new Cyprus systems use net billing. Power you use yourself is worth the retail rate. Power you export is paid much less. Batteries should take the first surplus. A miner only makes sense on what is still left, after the house, hot water and EV are served, at no extra electricity cost. That is the whole idea: Cyprus sun, used on site, twice if you have enough of it.
