Tires are complementary goods to car solar panels. Price & quantity of complements are inversely related. Lower priced solar panels imply higher demand quantity of tires. Increase & rightwards shift in demand implies competition among buyers & tires' price increase.
Oil is a substitute good to solar panels. Price & quantity of substitutes is directly related. Lower priced solar panels imply lower oil demand quantity. Decrease & leftwards shift in demand curve implies excess supply & competition among sellers, so price of tires decrease.
