One of the culprits all South Africans is fighting, is the rise of electricity prices. And even though the people have made it clear they are unhappy about the price hikes, Eskom continues to empty our pockets. It seems like a never-ending cycle of forking out money we work hard to get in the first place. But this is all about to change, because you’ve just found a way to bring down your electric bill substantially. Goodbye Eskom, hello endless solar power entity, it’s time to utilize solar geyser conversion.
The Retrofit Kit
A conventional geyser doesn’t come cheap. Along with installation you’re looking at amounts that easily surpass R3000 – at the least. This is only made worse by the fact that you know it’s going to take leadership of your energy usage. Before you know, the geyser is responsible for anything between 50 and 60% of the bill.
Assuming you just installed a new geyser, or the one you have is in good condition, but you still want to implement solar power due to the long-term cost – what do you do? If it requires getting a new geyser then it’s not exactly motivational, even though it will still save you loads of money. But what if you don’t have to make a geyser part of the package? What if you could simply take yours, and convert it to a solar powered heating system?
This is why the Retro Fit kit exists, because it turns your existing geyser into the most energy-friendly appliance in your home. The kit comes complete with a panel (collector), pump, timer switch and controller. Basically, it’s as affordable as a solar geyser system is going to get. Apart from saving you money regarding the equipment, you can cut another hour off the installation time.
The Retro Fit kit will work with all major brands and it will function with the same efficiency as any other solar heating system would. Of course the quality of the tank itself speaks volumes to its capabilities, but if you already own one you can consider it suitable for a solar connection.
How Solar Geyser Conversion
There aren’t too many complexities involved. Your geyser will stay in place while a solar collector gets attached to the roof. The collector and the geyser are connected with an inlet and outlet, through which the water is going to circulate.
The collector will use radiation from the sun to heat the water, and once the water in the collector reaches a temperature that’s 7 degrees higher than the water in the tank, the circulation starts automatically. Cold water from the tank flows to the collector while the warm water flows to the tank. This will only stop when the temperature of the geyser is 4 degrees lower than the water in the collector. This cycle should keep the geyser heated at 70 degrees during the day, and it’s all done with solar power.
Do You Need Eskom as a Backup?
If your system is large enough to serve the whole family with warm water it’s not really necessary to be tied to the grid. But you never know when it’s going to be a cloudy week, which will take away from the efficiency of the panel. So, it’s not going to hurt to stay tied to the grid, but you’ll rarely need it.
The Size of the System I Need?
Everything is going to depend on the size of your family, habits, and the size of the tank. But here are some guidelines to help you decide what type of solar geyser conversion system fits your need.
