Indian solar module plants are operating at an estimated 35-40% utilisation, far short of the 50-65% range needed for sustainable operations, according to a report from the Institute for Energy Economics and Financial Analysis (IEEFA) and JMK Research. The study is titled 'Assessing overcapacity risk in India's solar PV manufacturing market'.

India reached 233 GW of solar photovoltaic manufacturing capacity in June 2026, IEEFA said. Roughly 135 GW of further module capacity is planned or under construction, according to the report.

The imbalance runs down the value chain rather than across it. Module capacity is nearly 7 times cell capacity and 116 times ingot-wafer capacity, which the report describes as a deep structural gap upstream. That ratio leaves the assembly tier dependent on inputs the domestic base does not produce at matching scale.

Export demand is concentrated in a single destination. The US absorbed around 97% of India's module export volume in FY2026, IEEFA said.

On the demand side, the report identifies data centres, green hydrogen, and exports as the most credible new sources, offering an incremental 17-22 GW by 2030. Set against 135 GW of module capacity still in the pipeline, that increment covers a fraction of what is being built.

Consumer group Solar Citizens is campaigning to put plug-in solar regulation on the agenda when state and territory energy ministers convene at the Climate and Energy Ministerial Council on September 11, according to RenewEconomy.

The push follows a run of regulatory moves elsewhere. Plug-in solar became legal in Great Britain last Thursday, RenewEconomy reported. New Zealand said the week before that it would legalise the technology within 12 months.

Germany is further along. RenewEconomy reported that installed plug-in units there have passed three million. Germany and the UK both handled the safety question by capping unit output at 800 watts, around 3.5 amps, a level the outlet described as too small to overload any normal circuit.

The appeal in Australia rests on housing. More than a third of Australians rent or live in apartments, and for most of that group plug-in solar is the only solar they will ever own, according to RenewEconomy.

On output, an 800 watt system on a balcony or in a backyard produces around 1,000 kWh a year across most of Australia, the outlet reported.

Nineteen families from four communities in Ecuador's Intag Valley are building a 300-kilowatt run-of-river hydropower plant on the Aguagrún River, and they hold 90% of the equity, according to Mongabay.

The plant, named HidroAguagrún, captures the river's natural flows without a large dam or a water storage reservoir, Mongabay reported. The families come from the communities of Cerro Pelado, Chinipamba, Nangulvi Bajo and Barcelona.

The remaining equity sits with two nonprofits. Corporación Toisán and Fundación Futuro each hold a 5% stake and supplied more than half of the funding alongside technical support, according to Mongabay.

On the revenue side, Mongabay reported that the project is projected to earn USD 120,000 a year from electricity sold into the national grid, against expected operations and maintenance costs of USD 40,000 a year.

The plant has generated 11 permanent jobs in operations, monitoring and ecotourism, Mongabay said. Over the 30-year life of the installation, 345 people will benefit from the profits distributed.

The wider system the plant will feed is heavily weighted toward the same resource. Ecuador draws 78% of its electricity from hydroelectric generation, according to Mongabay. That concentration turned into a supply failure in 2024, when the country's energy crisis produced daily blackouts of up to 14 hours, hitting essential services, public health and social wellbeing, Mongabay reported.

Solar power can beat coal and gas on cost across the 74 members of the Climate Vulnerable Forum, according to a new report on solar costs cited by CleanTechnica.

The finding covers the full membership of the forum, a bloc of 74 countries, rather than a single national market.

CleanTechnica also reports that the findings carry implications for the growth of the US solar manufacturing sector.

The Barack Obama Foundation has taken the anchor tenant role for community solar projects developed by Reactivate in Illinois, Solar Builder reported.

Under the arrangement, the foundation gains access to solar output backing the sustainability goals of the Obama Presidential Center in Chicago, according to Solar Builder.

Valerie Jarrett, CEO of the Obama Foundation, said the Obama Presidential Center is sourcing 100% of its electricity from renewable energy, and that the partnership is with a company that will expand solar access to neighbors.

Residential and commercial subscribers are estimated to see 50% energy cost savings on their utility bills through Illinois Solar For All and other regional programs, per Solar Builder.

Tesla halted shipments of Solar Roof tiles in August and told its network of certified installers it would supply only conventional solar panels from that point on, Electrek reported.

The decision followed an internal conclusion that the product "is not financially viable," according to Electrek.

Volumes never approached what the company had projected. Electrek reported that Tesla installed roughly 3,000 Solar Roof systems across the US over about seven years. Weekly output peaked at 21 to 32 installations, more than 95% below Elon Musk's repeated promise of 1,000 installations a week by 2019-2020.

Installation labor was the binding constraint. A Solar Roof took roughly two-plus weeks to fit, against about two days for a conventional rack-mounted solar system, Electrek reported. That gap left certified installers carrying training and equipment costs against a product that turned over a fraction as fast as standard panel work, and Electrek reported the exit is leaving those installers with six-figure losses.

Tesla has said it will honor existing warranties and keep supplying replacement parts for Solar Roof systems already installed. Homeowners with the product on their roofs therefore retain a service path, even as the supply chain for new builds closes.

The shift redirects Tesla's certified channel toward conventional panels, the same hardware installers can fit in about two days. For a network built around a tile product that shipped roughly 3,000 units in seven years, the change removes the premium line without a like-for-like replacement.

Fervo Energy has signed an agreement to supply Google with nearly 400 megawatts of clean electricity from its geothermal project in southwest Utah, according to Canary Media.

Canary Media reported that the contract is the largest of its kind for a next-generation geothermal system.

The technology is an emerging one that involves drilling deep into hot, dry rock, according to Canary Media.

New Jersey Governor Mikie Sherrill signed the Garden State Balcony Solar Act, legalizing small, portable solar systems that plug into an ordinary 120-volt outlet, according to Electrek.

The statute applies to plug-in systems with a combined output of up to 1,200 watts, which Electrek describes as roughly two or three modern solar panels.

A lower tier sits inside that ceiling. Electrek reported that systems rated at 400 watts or less are exempt from code provisions that would otherwise require changes to the building, its wiring, or the electrical panel.

Renters get an explicit path. Tenants installing a qualifying system must give at least 14 days' written notice, state where the system will be placed, and submit documentation showing it meets the law's requirements, per Electrek.

Electrek reported that the law takes effect March 1, 2027.

Deltamarin and Offshoretronic have signed an Exclusive Engineering Consultant Agreement to develop the VITRUVIAN Class, described by Offshore Engineer OEDigital as the world's largest jackup Monopile Installation Vessel.

The design brief is driven by turbine scale. Next-generation 20-30 MW turbines are expected in commercial service by 2030, according to Offshore Engineer OEDigital. The foundations those machines require sit beyond what installation contractors can currently lift.

No vessel in the current global fleet can handle the new monopiles, with the existing ceiling around 3,000-3,500 tonnes, Offshore Engineer OEDigital reported.

The MPIV is engineered at 179 meters in length and 75 meters in beam. Those dimensions define a hull sized for the lifting and deck loads that the coming foundation generation implies rather than for today's monopile weights.

A companion Wind Turbine Installation Vessel variant will complete the VITRUVIAN platform, purpose-built to handle towers, nacelles and turbine blades, per Offshore Engineer OEDigital. The pairing splits the two installation campaigns, foundations and generating equipment, across separate purpose-designed hulls within one design family.

Under the agreement, the partners will take the design through to shipyard-ready status. That step ends at the point where a yard can price and build, ahead of any construction commitment.

The lifting gap is the commercial argument. With the fleet ceiling at roughly 3,000-3,500 tonnes and 20-30 MW machines targeted for commercial service by 2030, foundation installation capacity, not turbine supply, becomes the binding constraint on project schedules unless new tonnage is ordered and delivered in time.
