6 FAQs about [Reasons for the decline in solar power generation costs]

Are solar energy costs going down?

Over the last four decades, the costs of solar energy products — in particular, solar photovoltaic modules — have dropped by 99%. That is quite a dramatic drop, and it’s even more dramatic to know that the costs we have right now will continue to fall in the years to come.
