Solar panels on residential or commercial buildings

In Short

Solar panels on roofs or heat pumps in gardens could alleviate the demand for electricity from power plants.

A Few Details

Commercial or housing premises can install devices to lower their demand of electricity from the electrical grid, even if the investment in solar panels or heat pump may not be paid back before years.

A few downsides:
-Solar panels’ peak production around noon doesn’t coincide with the consumption peak of late afternoon and evening.
-Smart meters are required (i.e., with pricing of inbound and outbound electricity flows) to resell electricity to the grid, if allowed by the power distribution company.
-Renters will not install solar panels on a roof that they don’t own.
-Apartment owners will have to share the installation on their common roof.
