Why you should not wait to install solar panels.
It is true that the price of photovoltaic solar panels becomes cheaper every year. However, it is important to emphasize that at the same time other costs that are related to the installation rise. This includes: installer salaries, fees, etc.. Therefore waiting to purchasing solar panels is not necessarily cheaper. The more years you wait, the more years you miss out on years of free electricity. In fact, the savings that an installation generates today is far greater than the savings that you can expect to generate next year in the purchase of the installation components.
In addition, in the United Kingdom there is some government support that reduces the cost of installing solar panels such as The Smart Export Guarantee, and a zero vat rate however no one guarantees that these aids will be offered in the future, and they can represent good savings today.
