According to the U.S. department of energy's national renewable energy laboratory (NREL) to a new report, share development solar energy plan can boost the roof in the market, in 2020 in a distributed photovoltaic industry will account for as much as 49%.

Sold on to multiple owners, according to the report from the array allocation power will be held in common by expanding the number of people benefit from solar energy.

There is insufficient space on the roof of the small businesses, and - very important - the people who live in the apartment will benefit.

The report says, expanding the field will be made from now to 2020 increased by 5.5-11 gw of solar energy, equivalent to $eight billion two hundred million to $sixteen billion three hundred million in investment.

According to the NREL, 49% of American households and 48% of the enterprise can not build a photovoltaic array.

NREL energy analyst and the report's lead author David ˙ Feldman (David Feldman) said: "historically, photovoltaic business model and the regulatory environment for photovoltaic systems are not designed to expand the potential customers. Therefore, the economic, environmental and social benefits of distributed photovoltaic (pv) is not provided to all consumers. Shared solar plans to explore the market for partner companies and households."

The report shows that, if the package be reduced spending as a way to the market, so as to avoid the SEC rules, so it may not be regarded as for-profit securities, the report said it will affect the sharing solar energy plan works.

, the report said the government, the public sector, and the solar industry by introducing the local legislative measures such as establish transparency and standardization for the investors, can help promote the solar market share.
