Hermann Diels popularized the term pre-socratic in Die Fragmente der Vorsokratiker (The Fragments of the Pre-Socratics) in 1903. However, the term pre-Sokratic was in use as early as George Grote's Plato and the Other Companions of Sokrates in 1865.
The cost of a solar panel today is around $3 per watt, and the extra cost of installation brings costs up to $5- $6 per watt. Note: Installation costs for PV systems include both labor and the electronics needed to tie the solar array into your existing electrical system.
As of 2016, itâs approximately $3.00 per watt, installed. The average sized solar panel system is 5,000 watts, so this brings the total cost to $15,000. That 15k figure is just an average amount. Systems can cost more or less mostly depending upon a homeownerâs energy usage.
