Residential PV

A new EUPD Research report shows that a PV system can cover 39% of the power demand of an electric vehicle, but this potentially rises to 80% if storage is included.

Rooftop solar is just the start, as energy storage, smart electrical panels, and EV chargers enter the mainstream for solar owners. Here’s a guide to matching your solar array with some of the most popular accessories.

Tata has landed a $54 million deal from Kerala State Electricity Board Limited to install the rooftop capacity for domestic consumers across the state.

The Africa Solar Industry Association has recorded almost 2 GW of large scale project announcements since the start of last month with 18 countries planning new clean power infrastructure and including energy storage in the plants.

According to Asia Europe Clean Energy (Solar) Advisory Co. Ltd, demand for solar PV in China could “effortlessly” surpass 100 GW in 2022, following a year of “flat” demand in 2021. It adds that a “massive overcapacity” situation in the production sector is looming. Meanwhile, the distributed solar PV market is on track for huge growth, with potential for annual demand to reach upwards of 20 GW+ from next year.

Australia is a world leader in rooftop solar deployment, but the head of Queensland-based renewables company REA Global has criticized the nation’s solar installation standards for being out of date and unsafe.

A 10 kW PV system has been feeding electricity into the Swiss power network since 1982. A research team has investigated the performance of the array’s first 35 years of life and has found that solar modules can target – at least in temperate climates – service lifetimes of 35 years, and that the bill of materials matters, a lot!

Too big? Too small? Just right? Many factors need to be considered when deciding how large or small to make your rooftop solar array.

State body the NEA has given its provincial offices until July 15th to suggest counties where a solar mandate – which rises to at least half of all government roofspace – can be rolled out. Selected companies will be awarded whole-county contracts.

Although self-consumption of solar power is the optimal economic approach, the expense of household batteries at present outweighs the increased ability they offer to use electricity generated on the roof. Whether aggregated ‘virtual batteries’ offer better returns is an open question, due to lack of electricity company transparency.
