Poland allows home solar owners to pair panels with batteries up to 2.2 times system power without grid connection penalty
By Eve
An amendment to Poland's Renewable Energy Sources Act, effective 1 December, permits households with rooftop solar to add home batteries rated up to 2.2 times the photovoltaic system's power without that storage counting toward the installation's grid connection size, provided total grid exports stay below the solar array's rating. The change replaces an earlier rule that excluded storage only when its rated power matched or fell below the solar system's power. A 10 kW photovoltaic system can now be paired with a battery rated up to 22 kW, expanding backup and load shifting options for homeowners.
Why it matters
The policy shift may drive demand for larger residential battery installations in Poland, creating procurement opportunities for storage suppliers and installers serving the home energy market. It also signals regulatory support for distributed energy resources that can reduce grid export peaks and improve local resilience.

EMO Energy deploys 25,000 battery packs as Q2 energy delivery climbs 35%
EMO Energy deployed around 6,000 battery packs in Q2 FY27 (July to September 2026), bringing cumulative deployments to 25,000, a 31.6% increase from 19,000 at end June 2026. Quarterly energy delivery rose 35.4% to 3,807 MWh, supporting 25.38 million EV deliveries and 126.9 million kilometres of travel across India. The Bengaluru company estimates its operations avoided 7,868 tonnes of CO₂e emissions in the quarter, up from 5,809 tonnes in Q1.
Why it matters
Rapid deployment of battery infrastructure and rising energy throughput signal growing demand for commercial EV support systems in India, relevant for CPOs planning fleet charging or energy storage partnerships. The quarter on quarter utilisation gains underscore the operational scale needed to serve high mileage commercial vehicles.
UK homeowners weigh battery purchase timing as zero-rated VAT ends 1 April
A UK homeowner debating whether to install a home battery now or wait for a cheaper model faces a trade-off: a forthcoming unit may cost 10 to 15 per cent less, but delaying risks missing the zero per cent VAT relief that expires on 1 April, after which the rate rises to 5 per cent. The discussion, posted in the r/SolarUK forum, highlights uncertainty over first-generation product reliability and installation costs, with some commenters noting that backup power may justify the premium despite years without outages.
Why it matters
The April VAT deadline creates a near-term procurement window for residential storage installers and suppliers, potentially pulling forward orders that might otherwise wait for next-generation hardware. For charge-point operators eyeing vehicle-to-home or bundled energy products, the policy shift underscores how tax incentives shape customer timing and the competitive landscape for behind-the-meter storage.
Texas Powerwall owner calculates free overnight charging could save $717 annually versus Tesla's $800 credit
A Dallas Fort Worth homeowner with a 17 kilowatt solar system and two Powerwall batteries has analysed a year of meter data and found that switching from Tesla's fixed plan to a free overnight charging tariff could reduce annual electricity costs from $940 to $224. The homeowner noted that 63% of their grid imports already occur between 9pm and 6am, meaning overnight battery charging could cut daytime imports from 4,412 kilowatt hours to around 620 kilowatt hours. The analysis, shared on Reddit's r/solar forum, suggests the free overnight plan could deliver $717 in annual savings, though this depends on actively using the batteries to shift load from peak to off peak periods.
Why it matters
The case illustrates how time of use tariffs and battery dispatch strategies can materially alter the economics of home energy storage, a consideration for residential installers and utilities designing EV and battery charging programmes. It also highlights the growing sophistication of prosumers in optimising storage assets, which may influence future tariff design and grid service procurement.
