There are a few Myths surrounding implementation of Solar Panels and whilst once upon a time they may have been relevant, Solar Energy has become a real solution to South Africa’s power issues.
A Hybrid Solar Solution
South Africa’s climate is one of the best in the world for Solar, generating on average over 2,500 hours of sunshine per year. Solar Power, however, isn’t in itself a complete alternative to a 24/7 cost effective, clean, efficient power supply. The quantity of panels and batteries needed to guarantee power 24/7 would not be viable, however the power generated from Solar panels is free, clean and renewable.
Our Hybrid power solution harnesses Solar Power with batteries, a generator and a hybrid inverter. This combination provides a reliable, economical and intelligent system capable of uninterrupted supply all year round, whatever the weather. Giving peace of mind, security and safety, whilst saving you money on your power bills.
Dispelling The old Solar Myths
10 years ago, that may have been the case, however, panel prices have plummeted over the past decade (80% since 2008). Now solar energy is incredibly affordable and whereas free sunshine stays the same price forever, utility power becomes more expensive year after year.
There isn’t enough Sun
Solar irradiation levels do indeed vary, but South Africa receives enough sunlight to make solar a good investment. Solar panels will continue to produce a significant amount of energy even on overcast days.
Manufacturing Panels requires more energy than they’d ever produce.
According to a 2004 US National Renewable Energy Laboratory study (yes it’s quite an old study, but bear with us) analising several different panel technologies, it takes 1 – 4 years for the energy savings accumulated by producing electricity from solar to equal the energy cost of producing the panel. Solar panels generally have life expectancies of 30 years, so 87% – 97% of the energy produced by the panels is clean energy (i.e. no pollution and/or greenhouse gas emissions).
Since technology has improved significantly since 2004, estimates are now in the region of that energy payback (for monocrystalline and polycrystalline cells is) 1 to 2 years, assuming 4.7 peak sun hours per day.
