Kas, the owner has set up a spreadsheet to record the daily input, this is one way to 'enjoy' the panels - monitoring their progress and comparing it with weather information. He has had solar water heating panels for a couple of years, but without any form of metering, so there's no way to know if it's doing any good. With a regular metering regime and his new PV panels he can meter the PV, the day and night electricity, and the gas too, comparing tariffs and calculating income.It becomes a bit of a hobby, and one can look forward on sunny days to see what the score will be, a bit like anticipating a 5 day cricket match result.

The most important part of the solar water heaters are its solar panels. The solar panels are made of various materials. The preferred of them are silicon solar panels. They do have better advantages over other materials used for manufacturing solar panels. The silicon suppliers do supply the best materials for producing solar panels.
