With the rapid deployment of gigawatt levels of capacity, much of it into multi-megawatt installations, quality has become a concern for module product as well as system installations.  As an offshoot of quality concerns, production output (kilowatt hours) has also come into focus as PPA (power purchase agreement) or tender bidding often results in low remuneration per kilowatt hour.  For systems from which electricity is sold volume (more kilowatt hours) is crucial to profitability.  Because of this system and module due diligence has become important and insurance products are becoming more important as are operations and maintenance contracts.  As industries mature and deployment increases aftermarket products (such as insurance and warranties) become important revenue generators.   In the next several years there will likely be an overabundance of such products as well as shrinkage as the market becomes over served. It is crucial for new entrants (at all points in the value chain) understand that the photovoltaic industry continues to evolve and remains quite young in its history.  The profitable FiT model was a short lived phenomenon unlikely to be repeated.  As the industry grapples with developing pricing models that support R&D and quality control it must also cope with a rapid change from FiT to bidding processes.  The industry is currently not mature enough to make assumptions about which business model will provide the wining balance of profitable margins and value to customers.  Among the many misconceptions that need to be reversed is the successful selling of the photovoltaic industry product as a commodity, instead of a high value means of electricity production.
