Off-grid solar

Zola Electric’s new lithium iron phosphate battery system charges from solar and the grid and can power AC and DC appliances. It has a nominal voltage of 12.8 V and a nominal capacity of 50 Ah.

South Africa scientists have developed an integrated, solar-powered heat pump and refrigerator for use by food vendors in sub-Saharan Africa. The dual system is powered by two 90 W solar modules and repurposes waste heat.

The 2023 Consumer Electronics Show (CES), which is being held this week in Las Vegas, Nevada, features several new battery banks to portably store and deliver solar power.

With Russia intent on destroying Ukraine’s energy infrastructure, a network of NGOs is taking up the challenge to donate small and mobile energy supply solutions. Astrid Schneider, a member of clean energy nonprofit Eurosolar, shared the story of the small solar kits that are making a big difference, in this month’s edition of pv magazine.

While the climate summit held at Sharm El Sheikh last month prompted pledges of raised funding for solar lanterns and single-panel systems, the money allocated to date is woefully short of what has been estimated would be required to provide universal access to electricity this decade. Drew Corbyn of Netherlands-based global off-grid solar body GOGLA, outlines three urgent courses of action to accelerate access to electricity.

Growatt’s new 6 kW inverters have an efficiency rating of 93% and offer 12,000 VA of surge power, up to 500 V of input voltage, and 8 kW of PV input capacity.

The first post-pandemic update on the state of the world’s off-grid solar industry has painted a picture of domination by European companies, but highlighted the potential for new startups in West Africa and an increasing use of PV as a backup to unreliable grid supplies.

US manufacturer Jackery has unveiled Solar Generator 1000 power kits, which are designed for off-grid operations and emergency backup power.

The off-grid solar sector has shown resilience in the face of pandemic-related challenges, with 70 million people gaining access to electricity from early 2020 to the end of 2021. However, the ability to pay for solar energy kits has taken a hit.

India’s Statcon Energiaa has developed an outdoor inverter solution for microgrids that can integrate multiple energy sources, including renewables (biomass, wind, hydro and solar), battery storage, and diesel generators. It can deliver continuous, voltage-stabilized power to the loads and supports AC and DC coupling.
