The manufacturing industry must be able to integrate solar products with the high-tech industry as this is the industry being embraced by most in the 21st century. It appears for the industry to be viable; more people need to embrace this source of energy. The big systems have (costly) options to waste energy into dummy loads in extreme cases, but practically, the maximum wind penetration is around 10% of the average power use, In Western hemispheres this is currently also seen as a practical limit because of the limitations to place wind mills on land (people do not like the view). In the developing countries, affordability and usability are the vital keys to the success of the solar industry while in the developed countries, innovation, integration with the high-tech industry and profitability are the vital keys
