What you need to know about a Solar installation.

The effectiveness of your installation depends on the combination of the correct number and size of panels, the storage capacity of your battery bank and the choice of inverter-mppt-controller combination.

At Powerhour Solar we believe in the importance to determine and define your required outcome before you implement an installation and here are the important steps in the process that will result in an outcome that meets your expectations.

  • Start by determining your monthly electricity usage in kilowatts and break it down in an average daily consumption. You could do that by recording your meter reading over a period or by checking the reading on your monthly municipal account. If you record your meter at sunrise and at sunset you can differentiate between sun light and night time consumption. By checking your consumption during the night, you know the size of battery bank you need.
  • Determine which appliances are the major contributors to your consumption, such as geysers or stoves. Keep in mind that a single geyser use at least 3kW per hour and a stove can use from 1,2 to 1,5kW per hour. By installing a gas stove and or solar geyser you can reduce the size of your primary solar installation and your battery bank substantially. You can remove the non-essential items such as pumps, geysers and stoves, from the solar installation if you choose so.
  • If you know now what is your required usage during night time, then you can determine the capacity of your battery bank in kilowatts, and if you know the load that your house draw during the day, you can determine the number and size of PV Panels that will produce sufficient energy to charge the batteries whilst taken into consideration that your appliances consume solar power and you charged your batteries during the day.
  • Only after that you can determine the correct type and capacity of inverter.
