Frequently asked questions

Will I get hot water in the morning?

Will water be heated on a cloudy day?
Yes, though the collector will be able to collect just above half the energy it could capture on a sunny day, but heat can still be captured on a cloudy day.

What percentage of my electricity bill can I save through the use of a solar geyser?
With Solar Network you can save up to 15% of the bill. That is after you pay the monthly instalment! The saving increases annually as Eskom reviews the price of electricity upwards.

Will the Solar Geyser be a fire hazard during hot, dry weather?
No. The Solar Geyser's components are all non-flammable so even during strong sunlight, the system will not catch a light or give off any sparks. The majority of the Solar Geyser's components are stainless steel, aluminium and glass.

After signing a contract how long does it take to start saving?
On average it takes a day to get paperwork and site inspection done and then, installation of a solar geyser is a one day job. So, it takes less than three day to have the system running.

I don't own the property do I qualify for solar geyser lease?
The lease is signed between Solar Network and the Home Owner, not a tenant. However, the tenant can liaise with the Home Owner and also benefit!

How long is the contract?
Contracts are available in packs of 5yrs and 10yrs. It is also possible to reduce the contract period.

Am I entitled to the Eskom rebate and after how long?
Yes. SolarNetwork will apply for the rebate on behalf of the customer.The rebate will be paid into the account which pays the installments for the system.

How much is the rebate from Eskom?
Eskom pays amounts between R2 000 and R12 000, depending on the system.

How long does it take for me to get the rebate?
It takes six to eight weeks.

What happens if the Evacuated Glass Tubes are damaged or broken?
Firstly, evacuated tubes are very strong and they do not break easily, however, if the worst happens, solar tubes can be replaced very easily. Even though the water can still be heated even if some tubes are broken, it is a good practice to replace broken tubes immediately.

Can I use Solar Geyser with my existing geyser (Hot water System)?
Yes, but, your geyser must be a kwikot geyser which is less than 3 years old. Simple retrofit valves can often be used to allow the Solar Geyser to connect to your existing geyser; the hot water system can easily be automated so hot water is guaranteed regardless of sunlight levels.

Will my water get hot enough?
Yes, on a clear sunny day the solar geyser can get your water to boiling hot!

Can a Solar Geyser be used to produce large capacity of hot water?
Yes. a Solar Geyser can be connected in series or parallel to provide large scale hot water production for a commercial setting such as a school, hotel or office building. There is really no limit to the size of the system.

Does a solar geyser require any maintenance?
The solar geyser rarely requires any maintenance, they are very durable. However, should there be any need for maintenance, it is easy and cheap.

Are Solar Geysers a viable alternative to electricity geysers?
Yes, Solar Geyser System is an alternative to electricity geysers especially in Sub Saharan countries like South Africa; Averaged over a year, a correctly sized Solar Geyser System can provide 80% to 100% of a household's hot water needs. The hot water system can easily be automated with the electric operated geyser so hot water is guaranteed regardless of sunlight levels.

Is it really beneficial to buy a SWHS on account compared to buying cash?
SWHS, is an expensive type of equipment, the cost of having one installed ranges from R16, 000 and R30, 000. Since SWHS can reduce your electricity bill by almost half, if you buy on account the system pays for itself. That means your cash flow will not be affected.

Who will do the installation for me?
Solar Network will facilitate the installation, and both maintenance and installation are paid for by SolarNetwork.

How can I be assured that I get a quality SWHS?
We deal with the Eskom and SABS approved suppliers and systems. Both are listed on www.eskomdsm.co.za. These systems under go various rigorous tests before they are approved. So, you are assured of a quality product.

Does the use of solar geyser help the environment in anyway?
Using solar and other forms of renewable energy reduces reliance on fossil fuels for energy production, thus directly reducing CO2 emissions. CO2 emissions contribute to global warming, an environmental issue which is now of great concern. The average household can reduce CO2 emissions by as much as 20% by installing a Solar Geyser System.

What type of collector can I choose?
You can choose between a flat plate collector and an evacuated tube collector.

What type of collector gives best performance?
The flat plate is good because it has fairly good performance and looks good on the roof. The evacuated tubes are not aesthetically preferable, but, they give the best performance.

What happens if the flat plate collector is broken damaged or broken?
Although flat plate collector can easily survive hail and heavy rains, hard objects can easily break the collector glass. If that happens, the whole unit needs replacement.

What type of collector is suitable for cold conditions?
The Evacuated Tubes. Evacuated Tubes can be used in temperatures as low as -10° C, although performance is reduced in such extreme conditions but Good heat output is still achieved in mild sub-zero conditions as long as there is sunlight.Using flat plate collectors in these conditions may damage the collector.

How many people can a solar geyser sufficiently supply?
Generally, one person uses between 30L and 50L of hot water a day. Depending on how big your family is you can choose a geyser size of 100L, 150L, 200L, 300L and 350L. It is possible to connect the traditional geyser in line with the solar geyser to give a large quantity of hot water.
