This article explores the possibility of using solar panels to power a Chevrolet Volt. With a full charge allowing for a range of 35 miles and a battery capacity of 12.8 kWh, we will assess the area of solar panels needed to drive 70 miles daily. The efficiency of solar panels, energy costs, charging times, and tax rebates in Colorado are discussed. Practical considerations are also included, such as installation costs and energy output in various U.S. locations. Dive into the details on renewable energy and electric vehicles!

Solar Panel and the Volt By Paulina Kruse Volt Is this possible?
Chevy Volt • Electric plug in car • 1 full charge = 35 miles • Up to100 mph • With full tank of gas • 375 miles • Lowest price is $39,145 • Tax rebate ranges from $0- $7,500 • In Colorado, it is $6,500
Battery • Charging in a household plug takes 10 hours • Charging with a charge station takes 4 hours • Installation at a home costs $300- $1,900 • Estimated full battery costs $1.50 per day
How solar panel works Solar Panel Efficiency Solar Panels convert 11-15% of Light Energy To electricity. For our Calculation we’ll use 12% Efficiency.
Estimating Solar Panel output • Not consistent • Area • Climate • Season • Different type of panels • U.S. potential solar energy map • http://energy.gov/maps/solar-energy-potential
What is a kWh? • Watt- • Unit of power - Joule/Second • Kilo watt hour • A unit of energy • 3,600,000 Joules = 60 sec/min*60 min/hour * 1000 • U.S. Solar output map in kWh
How much area of solar panels using current technology would it take to produce enough electricity to drive a GM Volt 70 miles a day? • Denver gets 6 kWh/m²/day • Volt battery holds 12.8 kWh of energy • Range of Volt fully charged is 35 miles • Energy needed to go 70 miles is 2*12.8 kWh = 25 .6 kWh • Solar Panel Area Needed is: • Total Energy = Light Energy * Area of Panel * Efficiency of Panel 25.6 kWh = 6 kWh/m2 * X Meter2 * .12 • X = 35.5 sq Meters of Solar Panel • Roughly 20 feet by 20 feet.
General Costs Volt = $40,000 Charging station= $300 to $2,000 Time= 4 hour charge Solar panel = ? 1 sunny day Volt = 40,000 Time= 10 hour charge Solar panel = ? 1 sunny day
