Details

Helderberg Solar Energy is a renewable energy company that specialises in lowering the cost of energy for Commercial and Residential applications by using the latest innovations in green technology.

Hot water heating is a very cost effective option which with in conjunction with a correctly sized PV system could provide the best return on investment. By reducing the electrical load i.e. installing a solar hot water system, LED lighting, Gas stove etc. the PV system size required can be reduced.

A large battery solution may add significantly to the cost and would have a long financial payback time at current electricity prices. By reducing the load a smaller battery is required which can cut cost.

Many electricity users in South Africa, especially industrial, pay a very high tariff when they use higher amounts of electricity than normal during peak times.

In these cases a PV system may be used to limit the amount of higher cost electricity consumed by storing energy during the hours of sunlight and releasing it during the high cost periods.

What makes the photovoltaic systems cost affordable is the fact that the sun has infinite renewability. Unlike other sources of energy such as oil and hydro whose availability varies with time and climate, we have no evidence whatsoever that the sun will one day stop shining.

Once installed the photovoltaic (PV) system has little or no maintenance therefore making it affordable to maintain in the long run.

Grid-Tied Solar PV System

A pure grid-tied system with no storage or load management for a user with fixed rate power charges is a viable option for South Africa.

The system however will need to be significantly under sized to minimise the wasted energy generation as typically no surplus power can be exported.

Essentially the PV system has to be sized to generate only sufficient power for the base load during the day, i.e. the fridge, freezer, pool pump and other permanently on devices.

The low investment cost of a small Grid Tied PV system with a high self-consumption rate make them quite attractive especially for households where the family is at home during the day.

Hybrid Solar PV System (Grid-Backup)

If frequent load shedding continues each winter then there will be continued demand for grid-backup systems that can operate with no grid for prolonged periods of time.

Adding a battery or a hybrid inverter along with a battery makes it possible to combine the energy from the PV system with that from the stored battery to power at least the essential loads in the property.

The size of the battery required depends on the rating of the essential loads to be driven from it at times of no solar power being available.

Load shedding typically occurs during the evening peak in winter from 17:00 – 10:00. Therefor there will be little or no solar power available to supplement the battery.

An alternative solution for new installations is to use a combined PV and battery inverter, commonly referred to as a hybrid inverter.

It is however important to seek expert advice before ordering/installing a PV system. Power savings should be realized as soon as possible.

Helderberg Solar Energy values our customers and is proud to stand out as a pioneer in the renewable energy industry as far as technical knowledge, after sales service and maintenance is concerned. We are also a PV Green Card accredited company, take pride in our workmanship and in honouring our guarantees.

Our product range currently offers (Photovoltaic) Systems, Solar Geysers, PV Heat Pumps, Pool Heat Pumps, Solar Borehole Pumps and Low Energy (LED) Lighting.
