There is no perfect system. The ideal is to have the best of all worlds which is why hybrid systems are so effective.
We have an exceptional climate for solar in southern Africa. blessed with abundant sunshine, PV is a really great option for us. There is that dreaded ‘terms and conditions’ that come with just about every purchase.
The peak that your panels can produce will be impacted by shadow, cloud, rain, angle of the sun, daylight hours and ambient temperature. The only time your panels will over perform is in summer sunlight on a cold day!
The capital cost of a HYBRID system is down to the battery that you need for those dreaded hours of load shedding. The size of this battery can be minimised should you be able to decrease your nocturnal consumption (in the case of a residence) and converting some of the heavier items on the property to solar and gas. Geysers, pool pumps, stoves and driers are the usual suspects.
There is usually a few occurrences during the course of a year when we get a few rainy and overcast days in a row, this means you panels sometimes have as little as 10% their normal yield and that you will rely more on your battery, OR on Eskom depending on the type of system you have and the various settings that you may have opted for.
This is when still being connected to Eskom will have it’s advantages. The likelihood of there being load shedding when you have no solar and no battery are highly unlikely. There is still the potential for that to happen.
As a business, you can now depreciate your new solar system over 3 years. This buys you more stability, cheaper electricity and the security knowing that you can continue with business as usual when your competitors simply cannot.
There is no perfect system but a hybrid solution definitely comes close.
