The new Leader of the Welsh Conservatives in the Assembly has visited Sharp, in Wrexham, on his first official engagement.
Andrew RT Davies AM has toured the factory and met staff.
Sharp recently announced it was doubling the production of solar panels at the site and introducing a training academy for panel installers.
Mr Davies said: “This factory is a Welsh success story on a number of fronts.
“It plainly shows that there’s a growing appetite for solar technology and it demonstrates how jobs can be created from renewable energy.
“Green growth is vital for Wales and we need to encourage more companies like this to get involved and play a key part.
“The Welsh Labour government needs to look hard at its plans for building a green economy and come up with a coherent and detailed strategy. I don’t believe enough is being done to seize those opportunities and reap the rewards.
“There’s simply too much Labour emphasis on wind energy in Wales. We need promotion of a diverse range of renewables, including solar.
“I am delighted to be in North Wales on my first official engagement. It is important that we make sure businesses here don’t feel ignored and Sharp’s progress and job creation proves that real results are possible in this industry.
“Now we need the policies in place to help others follow suit.”
Andrew Lee, International Sales Manager at Sharp Solar said: “The potential for solar PV industry in the UK is huge.
“It empowers homeowners to safeguard themselves against rising fuel bills in the future, while at the same time providing the potential to be a key driver in helping reduce carbon emissions, contributing to the economy and helping get UK plc back in the black.”
