		<description>Solar is an old technology now and is fairly developed.  Cost is a bit of a barrier but that is coming down quickly.  Production scale could also be considered a barrier, as the industry can&#039;t yet make enough solar panels to satisfy demand.  The panels themselves are limited in how much energy they can take out of the sun&#039;s rays, but they are getting better at this.  Materials are a big thing now, mostly in trying out different materials and structures in the cells to bring down the cost and boost the efficiency. &lt;br&gt;&lt;b&gt;References : &lt;/b&gt;&lt;br&gt;</description>

		<description>I&#039;m really not following your question.  But currently there are no &quot;engineering&quot; challenges to photovoltaic, wind or passive solar energy.  What challenges there are is cost, efficiency and application knowledge.
You can email me for specifics.&lt;br&gt;&lt;b&gt;References : &lt;/b&gt;&lt;br&gt;</description>
