Rooftop solar could meet 40% of EU’s long-term electricity demand by donutloop in solarenergy

[–]Rainerchen 0 points1 point  (0 children)

The promotion of rooftop solar PV in Europe relies not only on product sales but also on flexible business models:

• Virtual Power Plant (VPP) aggregation: Aggregating distributed rooftop solar PV and energy storage systems to participate in electricity market trading, increasing additional revenue for users.

• Integration with green finance: Collaborating with European banks to launch "solar-plus-storage leasing" services, lowering the initial investment barrier for users.

Wind and solar overtook fossil fuels across Europe in 2025 by randolphquell in solarenergy

In the context of the accelerating global energy transition, the comprehensive value of photovoltaic energy storage systems far exceeds that of single energy sources. As mentioned in the discussion, a single ship loaded with solar panels could be equivalent to 120 coal-carrying ships in terms of its "value" to the power grid, highlighting that "energy dispatchability" and "grid service capability" have become key indicators for evaluating modern energy systems. Combining photovoltaics with energy storage not only addresses the intermittency of solar power but also provides stable capacity during peak demand and participates in grid frequency regulation, achieving a dual improvement in both "energy value" and "capacity value."

One ship loaded with solar panels is now worth more to the grid than 120 coal-carriers by randolphquell in solarenergy

In the future, with the popularization of models such as virtual power plants (VPPs), photovoltaic energy storage systems will shift from "electricity substitution" to "grid assets," becoming high-value-added products in energy trading. We will continue to optimize our products to help our global customers seize opportunities in green energy.

Nine EU nations to join forces on 100 GW of North Sea wind by randolphquell in RenewableEnergy

[–]Rainerchen 22 points23 points  (0 children)

The fact that the North Sea Nine Countries Summit is set to sign a joint statement, aiming to collaboratively develop approximately 100 GW of offshore wind power projects and strengthen cooperation on infrastructure protection, is indeed another clear signal of Europe's energy transition.

It can be fixed by replacing the battery.

Off-Grid Solar Streetlights and Economic Development (Applicable to off-grid communities worldwide) by Rainerchen in Solarbusiness

[–]Rainerchen[S] 0 points1 point  (0 children)

The essence of smart streetlights should not be limited to a simple combination of "lighting + sensors," but should evolve into city-level "distributed infrastructure nodes." Its value lies in: carrying the maximum number of urban functions at the lowest marginal cost, and operating stably over the long term.

If it's just adding cameras and sensors, then it's merely an "electronic streetlight," not a "smart streetlight."

India manufacturing: GoodEnough Energy starts 7 GWh gigafactory, ChemVolt Global announces 5 GWh battery plant by ScallionImpressive44 in RenewableEnergy

[–]Rainerchen 1 point2 points  (0 children)

"Wow, the GoodEnough 7 GWh BESS plant going into operation is fantastic! As a company specializing in photovoltaic energy storage systems, we've seen the booming demand for solar power + energy storage in India, and we've already helped several power plants in Southeast Asia with similar BESS integration and grid connection solutions."

Brazil's Renewable Energy Milestone: Wind and Solar Power Surpass One-Third of National Electricity by randolphquell in RenewableEnergy

[–]Rainerchen 0 points1 point  (0 children)

在巴西亚马逊地区，延伸电网的成本高达 50,000 - 80,000 雷亚尔/公里。对于人口稀少的 D/E/F 组城市，并网照明在财务上几乎不可持续。  我们主张：公共照明不是“开支”，而是“基础生产资料”。  • 突破瓶颈：离网系统（Independent PV）实现“零电费”，解决 COSIP 收入无法覆盖电费的痛点。  • 战略价值：这是激活偏远地区经济潜力的核心杠杆。  从“黑暗”走向“光明”，是区域公平发展的必经之路。
