Solar, inverter, battery news.
Jackery unveiled its Solar Roof system and SolarVault 3 home battery storage during a media tour at its Shenzhen headquarters. The integrated solution targets self-consumption — a key metric for European homeowners looking to cut grid dependency.
South-facing panels are not always the optimal choice for rooftop solar. An east-west roof orientation can deliver comparable annual yields with a flatter, more useful daily production curve — especially for households that consume energy in the morning and evening. Here is what every homeowner should know before deciding.
Germany's grid regulator Bundesnetzagentur estimates around 1,336 MW of new solar PV capacity was installed in May 2026, pushing the country's cumulative total close to 124 GW. The six-million-installations milestone was also crossed, underlining Germany's continued leadership in European solar deployment.
Combining rooftop solar panels with a home battery storage system can significantly reduce household electricity bills, but realistic expectations depend on many factors. Here's what homeowners should know before investing.

Buying a solar PV system in Hungary involves far more than comparing final price quotes. This guide walks through what to look for in an offer, which inverter type suits your situation, and how to realistically estimate payback periods in the Hungarian market.
Differ Power's D1 Series is presented as the world's first integrated 9-in-1 air-to-water heat pump combining PV inversion, battery storage, space heating and cooling, hot water, and home energy management in a single platform. The system will debut at Intersolar Europe 2026 in Munich and could cut installation time by up to 50% compared to conventional multi-vendor setups.
Cypress Creek Energy has secured $3.5 billion in financing for the first two phases of the Steel River Energy Center in Mississippi County, Arkansas — one of the largest combined solar and battery storage investments in the United States.
Partial shading is one of the most common challenges in residential solar installations. Power optimizers and microinverters can significantly reduce shading losses, but they also add cost. This guide helps homeowners understand when the investment makes sense.
Sizing a rooftop solar system for a Hungarian family home depends on annual electricity use, roof orientation, and whether extras like a heat pump or EV charger are planned. This guide walks through the key decisions to help homeowners choose the right system.
Combining a heat pump with rooftop solar is one of the most effective ways to cut household energy bills – but only when both systems are planned as a unit. This guide explains the key decision points for homeowners considering this combination.
Official figures show 3.5–3.8 GW of new solar in Africa in 2025, but Chinese export data analysed by the African Solar Industry Association (AfSIA) points to more than 16 GW actually installed. The real driver is not climate policy but economics: solar plus battery storage beats diesel generators on payback time. This decentralized, market-led PV revolution has implications far beyond Africa.
SolarEdge's Nexis inverter and battery storage system has been approved by six major U.S. residential solar financing platforms, lowering the barrier for homeowners to adopt integrated solar-plus-storage solutions.
Athens County, Ohio is offering a free Level 1 solar photovoltaic certification course — registration closes August 1. The initiative highlights a growing global trend: as rooftop solar installations surge, the demand for trained PV professionals is outpacing supply.
The City Council of Carson, California, has approved a new renewable energy storage system, reinforcing a growing global trend of municipalities investing in grid-scale battery storage to boost clean energy self-consumption and grid resilience.
A new 54 MW ground-mounted solar farm in Gerbstedt, Germany, shares its grid connection point with an existing 26.4 MW wind park on the same site. The approved hybrid grid concept cuts infrastructure costs and sets a noteworthy precedent for co-located renewable projects.
Solar, battery storage, and gas are driving new capacity additions in Texas's ERCOT grid. Sodium-ion batteries are headed to California, hybrid renewables break ground in New Mexico, and Avangrid completes a solar farm in Oregon — a snapshot of the US energy buildout.
Hoymiles and TÜV SÜD have jointly published a white paper focused on residential energy storage trends and standards for 2026. The document provides a reference framework for homeowners and installers choosing battery storage alongside solar PV systems.
Mexico closed 2025 with over 5.16 GW of small-scale, distributed solar capacity across more than 600,000 installations. The milestone highlights how residential and commercial rooftop solar can aggregate into grid-relevant capacity.
The US federal government is channeling $700 million into ageing coal plants, even as solar and wind power consistently undercut fossil fuels on price. The move reveals the political friction slowing an energy transition that market forces are already driving forward.
The Netherlands is facing severe electricity grid congestion, with distributors Liander and Enexis calling on solar PV owners to temporarily reduce feed-in during peak hours. Around 7,300 customers are waiting for stronger grid connections, and new priority rules take effect in July 2026.
Arctech Solar signed a 2,091 MW agreement for the UAE's ADQ solar project at SNEC 2026 in Shanghai, alongside a 1 GW solar-plus-storage MoU. Meanwhile, Chinese polysilicon prices edged lower as inventory pressure mounts – a development with direct implications for global solar module costs.
The Financial Times argues that squandering China's massive solar panel surplus would be irrational. For the global clean energy transition, this oversupply represents a historic opportunity — if governments and markets respond intelligently.
Recycling a modern solar module costs up to $45 in the US; landfilling it costs just $1–5. This economic gap makes crystalline silicon recycling commercially unviable without regulation — and a global waste surge in the 2030s is approaching fast.
Sunly and Rolls-Royce have signed the largest battery storage agreement in Baltic history, marking a major milestone for grid-scale energy storage in the region. The deal highlights growing corporate interest in large-scale storage as the Baltics prepare to synchronize with the EU electricity grid.
Malaysia is set to nearly quintuple its solar capacity — from 5.8 GW in 2024 to 29.7 GW by 2035 — according to GlobalData forecasts. The country is expected to hit its 2040 national renewables target nine years early, driven by large-scale tenders, green financing and improving grid integration.
California's Pacific Gas and Electric has connected over 1 million customers with rooftop solar to its grid, marking a major milestone for distributed energy and grid management worldwide.
York Space Systems has bought Solestial, a specialist manufacturer of solar panels designed for use in space. The deal consolidates space-grade photovoltaic expertise under one roof and underlines growing investment in high-efficiency solar technology.
A recent NERC compliance deadline is reshaping how owners and operators of solar, wind, battery storage, and hybrid assets must document and test their grid interconnection. Radian Generation experts break down the key requirements.
Cambodia has surpassed both its 2030 and 2035 utility-scale solar targets ahead of schedule, with nearly 1.5 GW already installed and solar covering more than 10% of national electricity generation, according to IEEFA. Zero import duties on solar and storage equipment introduced in April 2026 could cut project costs by up to 30%, accelerating what is already one of Southeast Asia's fastest solar build-outs.
