Many people see solar panels as a fantastic way to reduce energy bills and though hey can be a big investment to start with, they do save you significant amounts of pennies every year. This is entirely true, and whilst you can use them as alternatives for electricity, you can also have solar panels installed on your roof for specific purposes, such as heating up your water. Using the energy from the sun, you can heat up your tank without using any electricity whatsoever so when you run a bath, wash up or hop in the shower; you can get super hot water without a penny being spent! This is a lovely idea for those who want traditional gas and electric with a modern supply source for heating hot water. It also means that when the solar panel energy has been used you can easily go back to electricity and your tank can be set up to switch automatically.
