The best-known of these tools is probably the hand-held window squeegee, used to remove the cleaning fluid or water from a glass surface. A soapy solution acts as a lubricant and breaks up the dirt, then the squeegee is used to draw the now water-borne dirt off the glass leaving a perfectly clean surface.
Another way of estimating the cost of electricity would be the cost of an ordinary solar system, or $21,000 as shown in the example above. So the cost of a Tesla retrofit system would be in the range of $33,000 to $37,500.
How much does a Tesla cost? The current Tesla car line (Roadster, Model S, Model X) ranges in price from $68,000 to $138,800 before tax incentives for electric vehicles. However, the cost of Teslaâs new Model 3 (currently being rolled out this year) could be as low as $35,000. How much does a Tesla Model S cost? When wondering what the Model S will cost you, the answer depends on on the model you buy and the tax credits available. The Tesla Model S (pictured above) comes at a starting price of $68,000 in 2018, $3,000 less than a few years ago.
