Photovoltaic (PV)

Solutions

Photovoltaic 
(PV) systems

inverters, battery storage, solar panels and UPS configurations

Photovoltaic (PV) systems make use of the sun to generate electricity during daylight hours. If you have a hybrid PV system with batteries connected, then your batteries will supply the stored electricity to run your essential loads during power outages and when the sun is not shining. And because solar is a technology and not a fuel, there are no ongoing costs after installation as is the case with gas for example.

18-25% ROI each year based on electricity savings​

Right now, solar delivers at least an 18-25% return on investment each year based on electricity savings, far outstripping any other investment vehicle where you could place your money. Investing in solar to save on your electricity costs and secure your supply is the very best investment you can make right now for your home and business for the next 20-25 years.

Getting started

Calculating your 
energy needs

Calculating your electricity needs is the first step towards getting PV ready. A thorough examination of your electricity needs helps you determine the following:

The size and cost of the PV system you will need.

Fluctuations in your energy usage during the day and night and over the months to manage peak demands.

Energy saving measures you can implement to reduce your electricity use before installing PV so that you save on the costs of a bigger system simply by being more efficient.

Conducting a 
load analysis

By conducting a load analysis, One Energy will record the wattage and average daily use of all of the electrical devices that are plugged into your central power source such as refrigerators, lights, televisions, PCs, power tools, machinery and computer equipment. Some loads, like your refrigerator or electric fencing, use electricity all the time, while others, like power tools or large format printers, use electricity intermittently, known as selectable loads. Your loads will be split into essential and non-essential loads and then a system will be designed for your specific needs.

A thorough 
load analysis is a must

Some providers will ask you only for an electricity bill and attempt to provide a PV solution based on this, but the approach is fundamentally flawed and inaccurate since your bill cannot reveal day and night usage, selective loads or peak demands which need to be factored into your PV solution. A thorough load analysis is a must. One Energy will visit your premises, set-up loggers on your electricity distribution board for at least a week to ten days, and provide you with a comprehensive view of where your electricity usage is going, and what steps we can take to help you reduce it. We will also be able to provide a very accurate indication of what your savings will be depending on what size system and the solutions we specify for you, so there is no shooting in the dark.
