Pyramid Electronics has unveiled three-phase string solar inverters based on silicon carbide power devices. The inverters are available in power ratings ranging from 5 kW to 15 kW, including models with three maximum power point trackers.

Despite rising module prices and lockdown restrictions, the nation maintained its quarterly solar capacity installation above the 2 GW level in the second quarter.

The comparison of two solar cladded roofs in Sydney, Australia, one bare beneath its panels and the other adorned with native grasses and plants, has found the panels on the green roof were, on average, 3.63% more efficient, producing an average daily output 13% greater than the conventional roof. The improvements are believed to stem from the lower temperatures on the green roof, thanks to its plants – which also provided a plethora of additional benefits.

A 6 MW solar plant, coupled with a 15 MWh battery energy storage system, will meet the village’s day and night electricity requirements. Moreover, 1kW rooftop solar systems have been installed on houses.  

An Indian-Malaysian research group has investigated the effectiveness of several passive cooling techniques for solar panels, including the placement of plants around the modules or coir pith underneath them, both of which, surprisingly, offered good performance in terms of temperature reduction and power yield.

The switch from fossil fuels and nuclear will bring a jobs dividend thanks to the greater labor-intensity of renewables plants, according to a paper published by Finland’s LUT. However, the jobs dividend is unlikely to be evenly spread around the world, with Europe set to be a big winner.

The Swiss group has acquired an integrated solar roof system solution from an unidentified German engineering service provider for this purpose. The aim is grow this sector from a niche market.

The maintenance cost of an electric vehicle is estimated to be significantly lower than internal combustion engines, and studies show home solar furthers the cost savings and boosts carbon emission reductions.

A new report says solar-plus-energy storage will become an attractive investment option for commercial consumers in India as early as 2023 for electricity bill reduction. For high-tariff paying residential consumers, the system will reach grid parity post-2027. The report findings are based on the levelized cost analysis of solar-plus-energy storage systems for consumers in the Indian State of Tamil Nadu.  

Potential price rises of 14% for the solar home systems that are driving access to electricity in the world’s under-served regions could signal further arrested progress towards the UN goal of universal access by 2030.
