 Frequently Asked Questions

panels

What is a Solar System?
A simple solar system consists of a solar module/panel, a regulator/charge controller, a battery and your load.

panels

Where does the power/electricity come from?
The power is produced by the solar panels which generate electricity when exposed to sunlight. This power charges the 12 volt batteries.

app

How can I use my 240 Volt appliances?
An inverter is required to be installed in your solar system. The inverter will be connected to the batteries and will convert DC (low voltage electricity) to AC/240 volt electricity.

fridges

What does "load" mean?
Your "load" is the total electrical demand of all your appliances and is measured in watt hours per day or amp hours per day i.e lights, TV, radio etc.

cables

Do I need a special cable?
Yes, to avoid voltage drop, you will need cable of larger diameter than standard cable used in house wiring.

panels

Can I add to my system at a later date?
Yes. Solar systems are designed to grow with your needs. Additional solar panels and batteries can be added as required, but it is better to have a large battery bank to begin with.

meter

What is Voltage or Volts?
Voltage is the rating of the amount of electrical pressure that causes electricity to flow in the power line.

watts

What is a Watt?
A watt is a measurement of total electrical power.

watts

What are watt hours?
Watt hours are the quantity of electrical energy used or produced when one watt is used for one hour.

amps

What are amps?
Amp hours is the number of amps used or produced in a given hour equals the number of hours. Batteries are rated in amp hours.

generator

Do I need a back up system?
Yes, it is wise to provide for poor weather by having on hand a generator and/or battery charger or in automotive applications a battery management system.

regulator

Where does the power/electricity go?
The power produced by the panel flows through the cable, through a regulator and into the battery.

battery

Where is the power/electricity stored?
The battery is your storage of power. It is your "Power House" or fuel tank.

battery

How can I get power at night when the sun is not shining?
From the batteries which have received power from the solar panels during the day - your "Power House".

regulator

What does the regulator do?
The regulator/controller controls the amount of charge going into the battery from the solar module and stops the battery from overcharging.

regulator

Is it always necessary to have a regulator?
The safe answer is YES. Except in the case of the solar panel being a SELF regulating type panel.

battery

What is battery cycling? When does cycling occur?
Cycling is a partial discharge of a battery and then re-charging it to full charge. For example at night time your load discharges the batteries, without any solar charge coming into the batteries. As the sun comes up the next day the solar modules will charge up the batteries again.

clips

Can I change the alligator clips on my solar panels to something else?
Yes you can. The clips can be easily changed to other things e.g. Anderson plugs.

grid

How Does a Grid Connect System Work?
Solar panels or photovoltaic cells are usually installed on the north side your roof (where it has the most exposure) in order to capture energy from the sun, which is then converted to electricity.

By installing a Grid Connect System, your home and/or business will be connected to the main electricity grid that supplies power to your local area. As your system produces electricity, any excess electricity that you do not use is then fed back into the grid. For those times when you need more electricity then what you are producing, your Grid Connect System automatically transfers it back from the grid.

What type of batteries do I need?

How much power do I need?
