Answer
Quantity of solar panels increase , Price of solar panels decrease
Quantity of tires increase, Price of tires increase
Quantity of oil decrease, Price of oil decrease
Explanation:
Supply is directly related to technological upgradation.
So, technical upgrade will increase ie rightwards shift the supply curve. Hence, <u>quantity of solar panels</u> will increase.
Increase in supply will create competition among sellers, so the <u>price of solar panels </u>will decrease
Tires are complementary goods to car solar panels. Price & quantity of complements are inversely related. Lower priced solar panels imply higher demand<u> quantity of tires</u>. Increase & rightwards shift in demand implies competition among buyers & <u>tires' price </u>increase.
Oil is a substitute good to solar panels. Price & quantity of substitutes is directly related. Lower priced solar panels imply lower <u>oil demand</u> quantity. Decrease & leftwards shift in demand curve implies excess supply & competition among sellers, so <u>price of tires</u> decrease.
