A well-designed solution architecture helps to eliminate confusion, apply a holistic view, take customized approaches to each problem, and make continuous adjustments.
Enterprise Architecture
should not be defined only from an IT perspective as an Enterprise is a complex socio-economic-technical ecosystem consisting of interdependent
resources like people, processes, information, and technology with shared values
and objective, with emerging digital enterprise, this definition will include
customers and partners as well
Whereas in the case of Solution
Architecture, mostly IT solution related, you may just be focusing on
enabling or automating only a part of enterprise function/process, a partner or
customer related service. The
resources used to architect an enterprise are different (technology, process,
organization structure etc.) than the ones required for Solution, where it is technology-driven;
The Enterprise
Architect is looking at the entire enterprise and is operating at a
considerably higher level than the Solution Architect. Additionally, the
Solution Architect has been perceived in more of an IT only role. Finally most Solution
Architects are operating at a single business unit level and potentially even a
single application level, as opposed to the Enterprise Architect, has the needs to
have a view of the entire organization and the interaction between the entire
business and IT
Mix EA with SA
Activities: With the cost pressure that organizations have been facing, it
is observed that organizations have started looking at a more tactical approach
hence mixing EA activities with SA activities. Solution Architecture, as
part of Enterprise Architecture, has the following characteristics:
(1). It is the set of principles, guidelines, etc. that describe how the components and standards of the Business, Information and Technology architectures should be used or consumed in general business "solutions."

(2) It is the instance
of how these components are applied in a specific solution situation.
Either a general enterprise-wide solution or a business process specific
situation.
A well-designed solution architecture helps to eliminate confusion, apply a holistic view, take customized approaches to each problem, make the continuous adjustment, conform to the well defined industrial standards, making integration and communication easier, and make the tracking of emerging issues and inconsistencies between solutions easier
