Renewable Energy Manufactures/suppliers should use their own product to manufacture.

The manufacturers’ of Solar Panels and other forms of renewable energy with related support products manufactures/suppliers - should have at least the decency to practice what they preach what they market to the public.
That would be the best marketing approach I can think off.
If they believe in the product they manufacture/sell, they should utilize it to its fullest potential.
It will give the manufacturer the actual experience of utilizing the product on a daily basis, view and experience any shortcoming or improvements that are needed, implement the improvements and capitalize on that revision to improve the product and its performance.
This will instill confidence in the public to purchase the product.

PS
As with any new technology, PV will become more efficient, cheaper and cleaner to produce. In order for this to happen we (Governments / NGOs / Individuals) need to invest more time and money into making PV viable, e.g. through increased incentives, regulations, technical standards, R&D, manufacturing processes and generating consumer demand.
Just like the automobile industry, the manufacture used its own product.
Over the years the automobile industry and technology has evolved from the early 1900 to what it is today the year 2008.
I predict that in 10 years the automobile we know today will change drastically for the better, with new fuel technology and other modification that will improve its scales of economy and features.
