“These measures could contribute to a 5-15% saving on your energy bill,” reports Naidoo.
“This measure could contribute to about a 20-40% saving on your energy bill.”
“In my opinion, by following a process of changing your behaviour, then reducing your consumption through efficiencies, and then building a solar system that matches your reduced consumption, you will ensure / maintain a high yield on your energy investment. It is also worth mentioning that investing in green technology, for your home, increases the overall valuation of your property.” CLICK BELOW to view three steps to give your car a waterless car wash.
“An over-sized solution will bring about a low ROI, generate wasted energy, and a long pay-back period. An under-sized system won’t achieve maximum results.“Another consideration is your Rand kw/h rate of electricity (the Rand per unit rate of electricity which you are paying).
“The higher your Rand kw/h rate, the more financially viable an investment into solar, or energy-efficient, technologies will be. If you are paying a low Kw/h rate, solar may not be the right investment for you. You should then consider investing in the less expensive energy-efficient technologies.”A kw/h rate, which could be deemed as low for solar, is around R0.75 - R1.15 p/u, and high at R1.20 - R3.00 p/u.
“The list of approved products are available on the CoCT website, and most municipalities outside of the Western Cape have similar departments.”
“Last time I checked, the Western Cape alone had just over 200 registered energy companies currently operating. It may be wise to request some references.”
“Most companies offer maintenance contracts as an additional value-add. This means they will come out and clean and check-up on your system. The solution itself should come with a five-year guarantee / warrantee on the inverter. 25 years on the panels, one year on the mounting structure, and 20 years on your cabling (which are you main components).”
“Most solar rooftop solutions are fitted with ‘Solar Logger’. This monitors the output of the solar system and displays them in an easy-to-read format. “By adopting these measures, you should be able to achieve significant savings, in the smartest way possible for your household,” concludes Naidoo.
