A feed-in-tariff also credits customers for energy produced onsite. However unlike net metering, which provides bill credits in exchange for electricity delivered to the grid, customers using a feed-in-tariff are paid for the power they produce.

A heat pump is a device that takes heat from one source and moves it to another location through electric or mechanical means. Heat pumps may be used either to heat or cool

An off-grid system is not connected to the electricity grid, and therefore requires battery storage. In an off-grid system a solar technician needs to design a system that has enough power generation and battery storage to meet the home’s requirements even in the depths of winter when there is not much sunlight.

Thermal insulation is the reduction of heat transfer (the transfer of thermal energy between objects of differing temperature) between objects in thermal contact or in range of radiative influence. Thermal insulation can be achieved with specially engineered methods or processes, as well as with suitable object shapes and materials.
