As South Africa’s Department of Mineral Resources and Energy has declared May as this year’s National Energy Month, state-owned electricity company Eskom has called on citizens to use energy more wisely, including by installing solar panels.

GoSolr, a South African company selling solar panels, intends to invest 10 billion rand (about $536 million) to introduce the concept of renting solar panels and batteries to households to end the country’s energy crisis that has caused long-hour blackouts, the Western media reported on Thursday.

“That’s our mission,” Andrew Middleton, the company’s chief executive officer, was quoted as saying. GoSolr, together with “all the other companies combined, can end this crisis.”

In four years, the business wants to add around 500 megawatts of solar-generating capacity. Middleton told the media that it is an increase from its present 70 megawatts.

The company has reportedly drawn funding and investment from the continent’s biggest bank, Standard Bank Group Ltd., and African Rainbow Capital Investments Ltd., owned by South African billionaire Patrice Motsepe.

GoSolr targets the 2.2 million households with an annual income of over 360,000 rand (about $19,300), according to the media.

Overall, in March, the rooftop solar power in South Africa increased by almost 100% to reach 5,440 megawatts, compared to the previous year, with around 620 megawatts of that energy generated on residential homes, the media reported, citing the firm’s data.
