Max Yield Energy offers renewable energy solutions in the Western Cape and are based in Durbanville. Our advice, design expertise and honesty is our pride and if there is one thing you can be certain of if you contact us, is that you will get 100% honest advice (even if you don’t want to hear it as solar is not the right answer for all situations).
The owner has a National Higher Diploma in Electronic Engineering and has an in depth understanding of the solutions we provide. This, combined with our experienced installation teams that take pride in the neatness of their work, ensures that every client becomes an ambassador for our company.
Understandably, most people do not have in-depth knowledge of the various system options and the very first step we take when doing a consultation (after confirming the primary objective of our potential client) is to give them a basic overview of the types of solar systems out there.
The section below gives an overview of the most popular system configurations today. It is not a detailed analysis of the various system types, but should help most people to decide which system will meet their needs.
This is our most popular system for residential customers. This system gives you the freedom of being off grid, but because you have a grid connection available, you do not have to have a big battery bank to get you through days with no or little sunshine.
In other words, the significant expense you have to go to in order to make provision for 3-5% of the time of poor weather in a total off grid system is avoided.
As battery storage becomes better and more cost effective, the battery capacity can be increased over time to move to a total off grid scenario.
The biggest advantage of this system is that you are protected against power outages, while you are saving on electricity. The downside is that the system is more expensive than a normal grid tied system due to the batteries and the more expensive battery to AC inverter.
The MPPT solar charger provides power to the inverter and charges the battery bank.
The inverter is programmed to use battery and solar power to power the house / office.
Should the battery voltage drop below a set value, the inverter will seamlessly switch to grid power, protecting the batteries from discharging further.
It is important to design the system so that the PV panels, the batteries and the loads are well balanced to ensure that the system only goes to grid power in poor weather conditions or exceptionally high use of electricity (outside the usage the system was designed for).
It provides no protection against power outages (when Eskom goes down, the solar power goes down as well).
We do not have favorable net metering (power buy back) schemes to our disposal yet. There are some programs in place, but they do not make financial sense to small consumers. The one anomaly is the Drakenstein Municipal area in the Western Cape. They have a VERY good system in place. See our dedicated page for this.
Because we do not have good net metering schemes, this system does not make a lot of sense if you are not going to consume the power as you generate it (during the day). So it makes a lot of sense for most businesses, but not so much for residences.
