Frequently Asked Questions

What is the difference between a Grid Tied; Grid Interactive and Off Grid solution?

A Grid Tied solution needs the electricity grid or a generator to synchronise with in order to work. In the event of loadshedding and no generator or batterye bank to provide a reference point, your Grid Tied solution will not deliver any power.

A Grid Interactive solution has batteries incorporated into the solution and can deliver power in the event of loadshedding. Also known as a Hybrid system. This is not an inexhaustible supply of energy and effective management of consumption is recommended to ensure maximum benefit.

An Off Grid system consists of a solar plant; battery bank and/or generator. These systems are not connected to any type of grid such as supplied by Eskom or a municipality.

What happens when it rains for days on end?

In cloudy and rainy conditions Solar PV panels generate less power. Your reliance on the utility grid or storage (like batteries) would be greater during these times.

What does it cost?

The cost is relative to the value being created. The main benefit is that the customer will continue to enjoy a further 20 years of savings after the solution has been paid for.

Will a solar PV solution reduce my risk of power failures?

A Grid Interactive solution will reduce risk. The solution is designed with batteries and / or generator that will provide an electrical supply when the grid fails (loadshedding).
A Grid Tied solution will not reduce risk.

Can my Grid Tied solution feed back into the Eskom grid?

Feed-back to the Eskom grid is allowed provided the client follows the stipulated process to get approval. There are municipalities who do allow feedback onto the grid.

What factors will influence the feasibility of a solar PV solution?

There are a few key factors that need to be taken into account when it comes to the design of a system. Some of these are meant to ensure that over-generation does not take place. This is crucial to ensure economic feasibility, as is the quality of equipment, available roof space, roof orientation and gradient, shading challenges, geographical location and the current electricity tariff being paid.
