Create a logo for an online shop named "Cronex Shop"

The logo should be modern and minimalist, with two variants: one dark and one light. It should include the name of the shop, and on the left side, there should be a small photovoltaic symbol, signifying a connection to solar energy or eco-friendly technology. This logo design aims to convey a sense of sleek, contemporary professionalism while also highlighting the shop's commitment to sustainable practices. The contrast between the dark and light versions ensures versatility and adaptability across different backgrounds and mediums.
