Electronic Energy Audits & Services

Our Unique Energy Audits


Solterra Cape Town’s ‘Energy Audits’ (EA) are vital to customers who require a better understanding of their existing Energy Consumption patterns and usage with the aim to identify where costs can be saved.

Energy audits help to identify high energy consuming appliances, poor energy patterns and behavior which are then corrected. (There is a once-off cost for the Energy Audit which is fully refundable upon acceptance of the quote, CLICK HERE to see pricing.)

Energy Audits are conducted in order to best size and design a customized PV System to meet any client’s energy requirements and build adequate systems accordingly. We are the only Brand that incorporate local Weather Data into the configuration and design of all our PV systems.


Energy Audit Info


Solterra & Sustainable Energy CT leads are connected to distribution boards, (DB boards) to help us track and monitor energy usage levels and patterns. We log data from every individual circuit breaker in your DB board.

This involves keeping our specially designed Data loggers connected to your DB board for a 2 week period to capture electrical data profiles. Once the 2 weeks have past, we extrapolate the raw data and use our technical software and other resources in order to generate 2 different reports.

When we have satisfied our system requirements, these include your current  geographical rates, roof pith angles and other technical data, we then arrange an appointment with you in order to present both reports, (your Efficiency Report & PV Quote).

The efficiency Report takes first priority as it compares both the “post & pre efficiency” outcomes, after this we discuss the PV options available within your quote in more detail. Solterra will then further tweak the Efficiency Data to customize exactly what our client requires and is happy to proceed with.
