Introduction • Current PV business models principally revolve around the ownership of PV systems by individuals and utilities • Who owns and controls the PV facilities and the related flows of cash and other benefits determines the potential viability • FiT and NEM policies instituted were expected to grow the rooftop solar market in Malaysia • Rooftop solar power market is expected to gain momentum due to increasing public awareness and government support • Commercial and industrial uptake of solar to take off once a more economically viable business model is introduced 5
Benefits of Rooftop Solar Power Construction Site access Photovoltaic (PV) systems are at the point of consumption, thus do not require additional investment for access during construction or for operation and maintenance. Modularity They can be designed for easy expansion if power demand increases. Operation and Maintenance Primary energy Solar energy is freely available, and the PV system does not entail environmental costs supply for conversion to electricity. Peak generation These systems offset the need for grid electricity generation to meet expensive peak demand during the day. Mature Technology PV systems nowadays are based on proven technology that has operated for over 25 years Impact Investments Rooftop PV system costs help offset part of the investment needed for new power generation, transmission, and distribution in the power grid. Cost Fuel savings from PV systems typically offset their relatively high initial cost. Environment PV systems create no pollution or waste products while operating, and production impacts are far outweighed by environmental benefits. 6
Overview of PV Business Model Evolution 1 st Generation 2 nd Generation 0 Generation 3 rd party ownership and operation PV System supply ‘Full integration’ Business models focus on Business models driven by third parties Business models allow PV to become an manufacturing, supply and installation which develop projects and own PV integral part of the electricity supply and of PV systems systems, resulting in: distribution infrastructure - Reduction of hassle and complexity for end-user - Better access to financing - Leveraging of current incentives structure (especially for commercial building applications) End-user is the owner - Utility gradually takes on a Business models energy with variation facilitation role as PV market share of system: grows - Ownership - Operation control Utility is largely passive, providing net Utility gradually takes on a facilitation Utility becomes more deeply involved as metering and standard/simplified role as PV market share grows PV becomes major consideration interconnection, but otherwise, unaffected PV product is specialized PV product is less specialized PV product supply chain becomes ‘commoditized’ 7
International Solar Business Models 8
Solar as Digitalised Business
The Solar PPA Business Model • Solar purchaser or “off - taker” buys power from a project developer at a negotiated rate for a specified term without taking ownership of the system • Project developer procures, builds, operates, and maintains the system • PV system may be physically located on the off- taker’s premises (onsite PPA) or located remotely from the off-taker (offsite PPA) • It is a financial mechanism that allows the off-taker to accrue many of the benefits of solar power without owning a system. 10

Conclusions • Solar PPAs can provide a fixed price for energy generated removing exposure to price volatility and allowing for accurate and cost planning • Solar power is low-maintenance, reliable and passive, with no significant fuel supply risks, making it ideal for a PPA agreement • Significant cost savings to be made as grid power prices rise over time and the PPA rate remains stable • Customers can expect to see savings from the outset at least a certain % reduction on its energy bills within the first year of the agreement • The customer can exist the contract via novation or buy-out of the solar asset at any time • The challenge so far in Malaysia is understanding of the PPA contract, management approval (investment or pure savings), concerns on responsibilities (eg insurance and safety) and few actual installation showing examples of savings 22
