The electricity is generated by solar panels. The electricity supplier pays per unit generated. The electricity generated can be used in your home, so you don’t have to import from the grid.

for residential or commercial customers who generate their own electricity, net metering allows them to feed the electricity which they do not use, back to the grid by using a bi-directional meter. Net metering is in fact a billing mechanism that credits the solar energy system owners for the electricity they add to the grid. In other words, when a customer’s electricity generation exceeds the customer’s use, electricity from the customer flows back to the grid, offsetting electricity consumed by the customer at a different time during the same billing cycle. In effect, the customer uses excess generation to offset electricity that the customer otherwise would have to purchase at the utility’s full retail rate. Customers are only billed for their net energy use.

1. Collector When sun’s rays fall on a solar water heater collector, made up of either an Evacuated Vacuum Tube System or Flat Plate Collector System, the radiation heats up the water present in the glass tubes (in EVT) and metal tubes (in FPC) due to high transmittance of the covering glass medium. 2. Tubes The heated water is less dense, so it rises in the various tubes eventually reaching the tank at the top. The relatively colder and denser water in the tank descends into the tubes, in turn getting heated — this cycle continues. The Thermosiphon effect ensures the movement of hot water upwards into the tank because of difference in density, eliminating the need for an external pump.
