Everything You Need To Know About Photovoltaic Systems

By December 23, 2020January 4th, 2021No Comments

Photovoltaic (PV) systems also known as solar power systems, is a system designed to supply suitable power by utilising sunlight and photovoltaics. It’s a way of generating electricity that can be used by consumers.

What is PV Power?

When sunlight is absorbed by the PV panel, the solar energy loosens electrons from their atoms, allowing them to produce electricity by passing through the material. The PV (photovoltaic) effect is where the conversion of light (photons) to electricity (voltage) happens.

3 Major Components of PV Systems

PV Panel

As we have mentioned previously, solar panels work by allowing particles of light (photons) to knock electrons free from their atoms, thus producing a surge of electricity.

At NuPower, we only use A-grade, tier 1 photovoltaic panels. And since they come with a 25-year, 80% performance warranty, it means that even after 25 years of use, your solar panels will still be working at 80% capacity. 


An inverter converts DC power to AC power. The appliances we use in our homes, as well as the grid, require AC power, and since solar panels produce DC power and batteries also store DC power, an inverter is needed.

At Nupower, we only use the best inverters on the market: the Easysolar and Victron Multiplus. These inverters can easily handle a flow of more than twice its stated capacity. They are completely programmable to regulate the output, and they also offer efficient protection of the batteries.

Batteries (Lithium)

At the risk of stating the obvious, batteries store excess electricity for future use. It acts as a back-up should there be a power outage to allow uninterrupted operation of appliances. With an expected lifespan of 5-8 years, it will continue to work, but you will notice a reduction in standby time.

Nupower offers high-quality, affordable PV systems to South Africans

There are many solar power companies in South Africa, but one name stands out from the rest — Nupower. It is because Nupower has extensive experience and more than 16 000 satisfied customers to show for it.
