SolarCity (SCTY) announced its latest investment fund with JPMorgan (JPM), which is expected to finance more than $350 million in solar power projects.

This is the second created by the two companies, and a follow-up to a fund created to finance approximately $170 million projects in 2013.

As a result, it makes it easier for homeowners to financially afford installing solar panels since it eliminates upfront cost, in addition to reducing their utility bills.

This is just the latest announcement in a recent push for solar energy.  

In mid-December, SolarCity announced it created a new investment program with BofA Merrill Lynch (BAC) to finance an estimated $400 million in solar power projects in 2014 and 2015.

And now that solar-power projects are growing and becoming more affordable, appraisers are emphasizing the need to properly figure out how to assess the value of the technology.

“It will take a while for people to come to understand the system,” said Sandra Adomatis, SRA, LEED Green Associate.

How much a homeowner will make back by having solar power features depends significantly on location, she explained. If a homeowner's electric rate is above the regular 11 or 12 cents for a kilowatt-hour, there can definitely be value in the system.
