🦁 Off-Grid Solar Meets the Wild: Sunways Powers a Farm Next to Sasan Gir Lion Sanctuary

In the shadow of Gujarat's famed lion territory, a farm now runs entirely on its own energy — no grid, no noise, no compromise.

We're proud to share this installation powered by Sunways and supplied by our trusted partner Grineu.

📍 Location: Sasan Gir, Gujarat
🔋 System: 6kW single-phase low-voltage hybrid inverter (STH 6KTL-LS) + 10kWh battery (STE-MS10)
⚙️ Mode: 100% off-grid
☀️ Daily generation: 20–30kWh
✅ Status: 24/7 independent power supply, self-sufficient and reliable

In areas where the grid doesn't reach — or doesn't stay — solar storage isn't a luxury. It's the only way to keep lights on, water pumping, and life moving. This farm now runs on clean, silent, stable energy, day and night.

Big thanks to Grineu Solar for sharing this success and for their continued partnership.

🇵🇱 Poland Solar + Storage: Not a "Wait-and-See" Market Anymore

Poland is one of Europe's fastest-growing solar + storage markets—powered by three-phase grids and high electricity prices.

What's changing in 2026?
Storage subsidy threshold 12kWh → ≥20 kWh
Mandatory EMS + off-grid capability
Grid connection → stricter certification (PTPiREE listing required)

📊 Market momentum
PV total: 24.8 GW → 59 GW by 2035
Storage: +102% YoY growth

⚙️ Sunways for Poland
Sunways delivers three-phase, high-voltage hybrid solutions already aligned with Polish requirements:
STH-4~12KTL-HT(-P) → residential ready
