Making the move to solar power is an excellent way to save on your electricity costs and free yourself from loadshedding. Ensuring that you appliances are efficient will increase your savings and improve your experience of solar power.

Consider these tips:

LED lighting - if you haven’t already done so, switch all the light fittings in your home with energy efficient LED bulbs.

Energy efficient appliances – Replace old appliances, such as fridges, with modern energy efficient models with at least an

A rating efficiency grade.

Geyser 1,2,3 – steps to make your electric geyser more efficient: lower the thermostat temperature, insulate your geyser with an insulating blanket, put a timer on your geyser to maximise it’s usage during daylight hours

  1. Maximising your solar production

MAXIMIZING SOLAR PRODUCTION The decision to install solar in your home should not only be a short term solution to the problem of loadshedding but should also be considered as a long term investment with the ability to reduce your electricity costs over time. Maximising your solar production with the following tips will help you achieve the greatest savings. 

CHOOSE A HYBRID INVERTER WITH BATTERY BACKUP: Investing in a hybrid inverter with a battery backup is your first step toward savings. With this system in place, your home can draw power from solar panels while staying connected to the grid. Essential appliances like your geyser, ovens, air conditioners, and pool pump can run on solar energy. During load shedding, your inverter seamlessly switches to solar power or battery backup, ensuring you're never left in the dark or without power. 

OPTIMAL PANEL PLACEMENT: The direction and placement of your solar panels matter. Our installation teams will install you panels in the most suitable direction to provide best results. Once installed you should keep an eye of nearby trees and foliage and prune accordingly if you notice shadows being cast over your panels. 

BATTERY OPTIMIZATION: While it's comforting to have a fully charged battery ready for load shedding, it may not be the most cost-efficient approach. Analyse your average consumption during outages and adjust your battery retention accordingly. By analysing your average consumption during loadshedding and setting your battery retention to meet only that demand, any excess stored power can be used to power your home instead of using the grid. 

 TIME YOUR APPLIANCE USE: Solar panels generate power when there's demand during daylight hours. To maximize savings, schedule high-energy-consuming appliances like geysers and pool pumps to run between 10 a.m. and 3 p.m., when solar production is at its peak. Using Wi-Fi timers can help manage this effectively, ensuring consistent consumption throughout the day.

  1. Upgrading your system 

UPGRADES Our solar power and battery backup systems are modular and it is possible to upgrade your system after it has been installed. Our solar consultants will help you to assess the performance of your current system and optimize it as far as possible, thereafter they will assist you with upgrades to achieve the following objectives: YOU WANT TO SAVE MORE YOUR MY UTILITY BILL Additional solar panels will help you increase your savings potential. Please bear in mind that the inverter model that you have will determine the maximum number of solar panels that can be connected to it. YOU WANT TO MAXIMISE YOUR SOLAR POWER GENERATION If you find that your solar panels not producing power for a large portion of the day due to low daytime consumption, adding an additional battery will help you store solar power to be used in the evenings. YOU WANT YOUR BATTERY TO LAST THROUGH LONGER PERIODS OF LOADSHEDDING If you find that you battery does not have sufficient capacity to last you during an extended grid outage you can add additional batteries to your system.
