Solinteg unveils hybrid inverter series for C&I applications
The Chinese manufacturer said the product line includes five models with outputs ranging from 25 kW to 50 kW, supporting charge and discharge currents of up to 150 A.
The future arrived early: Why our energy cost forecasts need to catch up
While solar modules and batteries have become icons of rapid progress, most energy models are still stuck in the past. A new global analysis shows that the cost of renewable energy has fallen far faster than expected. Solar PV, wind power, and battery technologies have already reached price levels that models once placed many decades ahead – a misplaced pessimism that risks misdirecting billions in climate investment and could distort long-term defossilization strategies.
Idemitsu developing CIGS solar modules for satellites
Japan’s oil giant Idemitsu Kosan and U.S.-based Source Energy Company announced a collaboration to develop copper indium gallium-selenide solar modules and arrays for satellite and space applications.
GoodWe releases new residential all-in-one storage solution
The Chinese company says that its new ESA series is available with a hybrid inverter ranging from 3 kW to 10 kW and storage capacities of 5 kWh to 48 kWh. The IP66-rated product supports an MPPT current of up to 20 A on the PV side and allows 200% PV oversizing, according to the manufacturer.
Indonesia expected to reach 23.2 GW of solar by 2035
UK consultancy GlobaData projects Indonesia will surpass 1 GW of cumulative solar capacity this year, before growth accelerates towards 9.1 GW by the end of the decade and 23.2 GW by 2035.
Outdoor testing identifies factors contributing to perovskite solar cell degradation
Tests conducted by a research team in outdoor environments in Spain and Poland have demonstrated a strong correlation between perovskite solar cell degradation and the combined effects of climatic and operating conditions. The scientists found that open-circuit operation accelerates degradation, whereas operation at the maximum power point and under short-circuit conditions has a lower impact.
