You'd be wrong. Modern electronic computers started to be made in the 1960's. Mechanical devices that could perform numerical functions have been around for thousands of years. The first gold-selenium photovoltaic cell was invented in 1883 by Charles Fritts. It uses the EXACT same principle of operation that current PV cells use. The "modern" version was invented from that basis by Bell Labs in 1954. Since then, there has been little change in the science other than to improve materials and production methods.
Also, the chemistry is well known and understood. You cannot get more than around 2 VDC out of a single solar cell. The ampacity of each cell is determined by its size and to a lessor extent the quality and purity of the materials used in making it. It is also well understood that these cells, like any other form of battery, lose potency over time. PV solar panels lose between 1 and 2% of their capacity per year. When they get down around 70% it starts being an issue as the voltage produced starts to fall off meaning it can no longer be converted easily to equivalent AC power. Thus PV solar panels have a run life of between 20 and 30 years.
With wind, the biggest issue is aeolian dust that literally sandblasts the turbine blades resulting in a massive increase over expected wear. There are also ongoing issues with off-shore wind and corrosion.
As for storage, this is just and added unnecessary expense if the systems were reliable. For solar the capacity factor is usually between 20 and 25%. That means you need 4 to 5 times the actual output capacity to get one KW day of power out of a solar plant and need to have storage for 4 to 5 times the plant's output. That is utterly insane.
The answer is nuclear and natural gas. It's that simple.
