The solar industry has undergone significant changes in the past few years. The price of PV panels has fallen by over 40% since mid-2008, due to a combination of factors such as reduced demand and increased supply of the polysilicon material used to make the panels.
Providing electricity at a price competitive with local utilities without the benefit of incentives and subsidies is the aim of the solar industry.
By adopting solar resources, companies can make a difference by enhancing energy efficiency and productivity; supporting clean, reliable and affordable energy technologies; and enhancing quality of life for everyone.
Like hydropower, solar has no fuel costs; but solar has two distinct advantages over hydro and wind:
- More opportunity for plant locations
- Solar PV requires no moving parts
- Solar energy flows directly from the source to the consumer, and any excess can be sold back to Eskom.
- Solar generation is the only mainstream technology which can claim to have unlimited fuel and no moving parts
- PV devices offer an excellent alternative to traditional means of generating electricity.
