Solar Power solutions have become very attractive to a wide range of customers, who have started using them for energy generation and other applications. The demand for residential, commercial and industrial usage of renewable energy is increasing day by day. It’s time for people across the world to start exploring and implementing cost-effective and reliable solar powered solutions at home or anywhere.
Customized to help you lower or completely eliminate your monthly electricity expense. Residential solar electricity system for homes is probably one of the largest home investments you’ll ever make.
The name speaks for itself in that this system is a combination of the Grid-Tie and Island Systems. The system does require batteries which makes it more expensive than a Grid-Tie System, but not as many batteries as the Island System. It requires fewer batteries as it is still connected to the Eskom Grid
The solar panels generate energy from the sun.
This energy converts from DC to AC current through an Inverter and charges up your battery bank. The batteries are your back up for evening use.
During the day your house will run off the ‘solar energy’ with any extra energy charging your batteries.
At night or when there are periods of low ‘solar energy’ during the day, your system with the use of a Inverter will then draw from the battery back-up.
A drawback to the system is that it has a limited number of batteries which means that should we have really bad weather for a few days in a row that don’t allow the solar panels to generate enough energy you may still need to tap into the grid for some of Eskom’s power.
Major positives about this are that most of the time you will not have to worry about load-shedding or drawing power from Eskom.
This is the kind of system you would use if you are in a more remote area where there is no access to Eskom power or if there are big problems with power cuts for days or weeks on end.
The solar panels generate energy from the sun.
This energy converts from DC to AC current through an Inverter and charges up your battery bank. The batteries are your back up for later use.
During the day your house will run off the ‘solar energy’ with any extra energy charging your batteries.
At night or when there are periods of low solar energy during the day, your system with the use of a Inverter will then draw from the battery back-up.
A drawback to the system is that it is the costliest of all of the systems available and that is normally due to the cost of the high number of batteries that are required to keep you running at all times.
Major positives are that once you have installed this you never have to worry about paying for electricity or having load shedding again.
Here’s an example:
You live in Cape Town and your monthly electricity consumption is 450kWh (450Units). Your area’s monthly peak sun hours are 145 (4.7 x 31 days) and you want to use a 450-watt solar panel to make up your entire solar system.
(450kWh ÷ 145) = 3.1 x 1000 = 3100 watts hour. You will need a 3.1kW solar system to offset your monthly energy consumption. 3100 watts ÷ 450 watts = 6 solar panels required.
When Eskom cuts the power, essential appliances often become non – operational. This is not only annoying but can make the lives easier for burglars. With the correct back up system, these features can remain functional, thus allowing peace of mind. Here’s a basic list of those possible essentials and extras if you like.
