Rising Electricity Costs Are Changing the Solar Conversation

During the height of load shedding, many systems were purchased under pressure.

The immediate goal was continuity. Customers wanted to keep essential appliances, equipment and operations running when the grid was unavailable.

Today, the conversation is becoming more considered.

Customers are asking:

• How much electricity can we generate ourselves?
• How can we reduce our monthly electricity costs?
• Which part of our consumption should solar cover?
• Is battery storage necessary?
• Can the system expand as our needs change?
• What will provide the best long-term value?

These are better questions because they move the focus away from simply buying equipment and towards understanding the customer’s actual energy needs.

One of the most important parts of solar planning is understanding when electricity is consumed.

Consider three very different customers.

A commercial facility may use most of its electricity during daylight hours, when solar production is naturally at its strongest. In this case, much of the generated energy can potentially be used directly by the business.

A household may consume relatively little during the day but considerably more in the early morning and evening. Its system may therefore require a different balance between solar generation, battery storage and grid consumption.

A dairy farm may have time-sensitive loads associated with milking, cooling, refrigeration and processing. The largest electrical load is not always the most important one. The operational consequence of interrupting a process must also be considered.

Our work on agricultural projects such as Blomfontein Dairy Farm has reinforced this principle. Before deciding on system size or equipment, it is necessary to understand the farm’s working day and the processes that cannot simply be moved or paused.

It can be tempting to assume that installing more panels or more battery capacity will always produce greater savings.

That is not necessarily the case.

• A system that is too small may fail to make a meaningful difference to the customer’s electricity bill.
• A system that is unnecessarily large may generate energy at times when the customer cannot use it effectively.
• Battery storage can be valuable, but its role should also be clearly understood. It may be used for evening consumption, critical operations, tariff management or greater energy independence. Each of these objectives can result in a different design.
• The goal should not be to install the most equipment possible.

The goal should be to develop a system that uses the available investment effectively.

A responsible assessment should consider more than the latest electricity account.  It should examine:

Historical electricity consumption

• Ideally, the assessment should consider at least 12 months of electricity information to identify seasonal changes and longer-term patterns.

The time of electricity use

• Daytime, evening and overnight consumption influence how solar generation and storage should be balanced.

Operational priorities

• Homes, farms, healthcare facilities and commercial businesses all have different loads that may need to be prioritised.

The applicable electricity tariff

• Energy charges, fixed charges, capacity charges and time-of-use structures can all affect the financial outcome.

Future growth

• New machinery, electric vehicles, business expansion or changes to the property should be considered before the first installation takes place.

Monitoring and ongoing support

• Long-term value depends partly on whether the system can be monitored, maintained, adjusted and expanded over time.

Solar remains a valuable tool for managing electricity costs, but its effectiveness depends on the quality of the planning behind it.

Two customers with the same monthly electricity bill may require completely different systems because their consumption patterns, priorities and future plans are different.

This is why Specialized Solar Systems begins with the customer’s energy profile rather than a standard package.

We assess how the property or operation uses electricity, identify the objectives and then design the solution around those requirements.

The equipment comes later.

Electricity tariffs are likely to remain an important consideration for South African homes, farms and businesses.

The right solar solution can help reduce dependence on increasingly expensive grid electricity, but it should be based on accurate consumption information and realistic financial objectives.

Specialized Solar Systems has been designing and supporting residential, commercial and agricultural energy solutions since 2008.
