Solar cleaning related operating costs can be reduced by approximately 30 to 40 percent through robotic systems, particularly in high soiling environments. In addition to direct cost savings, consistent cleaning stabilises direct current input to inverters, reducing electrical stress and lowering fault incidence.

Indian scientists have fabricated perovskite mini-modules with reduced graphene oxide interface engineering, achieving 16.6% efficiency and over 1,300 hours of stable operation. The graphene oxide layer improves film quality, reduces defects, enhances charge transport, and enables scalable fabrication, offering a promising route toward efficient and durable perovskite solar modules.

The move toward decentralized energy resources offers resilience and flexibility in power generation, but it also introduces new complexities that demand proactive security measures.

The project combines 1.35 GW of photovoltaic capacity with 150 MW of molten-salt tower concentrated solar power. It is located in Xinjiang and requires an investment of $950 million.

In a new weekly update for pv magazine, OPIS, a Dow Jones company, provides a quick look at the main price trends in the global PV industry.

A review of 60 renewable energy studies finds that by 2050, solar PV and wind could supply 80–100% of electricity, but overly conservative Capex assumptions and simplified PV modeling often underestimate deployment potential. While future PV costs depend on supply chains and geopolitical risks, historical experience suggests medium-term risks are manageable, and material constraints are being resolved.

The new Anker Solix Solarbank Max AC steps up from balcony-scale storage with a 3.5 kW inverter, plug-in capabilities for do-it-yourself (DIY) ease of installation, and expandability to 42 kWh, priced from €2,229.

The U.S.-Israeli conflict with Iran is unlikely to materially affect solar manufacturing projects in the Middle East for now, as most of these investments remain at an early stage. OPIS analyst Brian Ng sees the most immediate risk in logistics. If disruptions persist, shipments of solar products into the region could be delayed and export pricing may turn volatile.

Wood Mackenzie’s latest analysis explores how 13 of the world’s leading power markets are impacted by the current fuel crisis, with those most reliant on fuel imports facing the greatest risk exposure. The consultancy says the average cost of generation is set to increase by $2.30/MWh across these 13 markets if a de-escalation of the conflict enables fuel price moderation in the latter half of 2026, increasing to an average of around $8.30/MWh if current elevated price levels persist through the year.

Polysilicon prices have fallen sharply over recent weeks due to persistent oversupply and weakening demand, briefly dipping to low levels before stabilizing slightly above CNY 50 ($7.31)/kg, though still near historical lows and below production costs. OPIS analyst Summer Zhang tells pv magazine that despite policy signals and potential future regulations, unclear implementation and continued excess capacity mean market conditions remain weak, with further demand declines and possible production cuts or discounted sales expected in the near term.
