Why has solar power become cheaper?

The Technology Itself Got Cheaper

Of course, a functioning solar power plant costs more than that because complementary equipment is needed, and on top of that it is necessary to cover the construction cost and the financing cost. However, photovoltaic modules themselves are now cheaper than ever before.

Is solar cheaper than electric?

Although solar energy costs initially to purchase and set up, people find that solar energy is a lot less expensive than electric power in the long run due to the rising price of electricity.

What are the 2 main disadvantages to solar energy?
