Urban Solutions: How to Use Solar Energy at Home?

During the last decade, solar applications for home use have grown at a rapid pace. We challenge you to go back in time, just a few years ago, and imagine how the promise of an efficient and competitive source of renewable energy was a distant dream.

Today the use of solar energy at home has become a reality that can be achieved by anyone. The truth is that the installation of solar panels for home has been growing worldwide. The phenomenon is explained by the significant reduction in the prices of solar products and by the increasing efficiency of solar panels as well as other systems, like solar water heaters.

Solar is sustainable and takes advantage of the sun as a source of clean energy, in order to fulfill the totality of our needs. After the installation, you need to adapt your home and channel the new kind of electricity or water to the different rooms of your house.

If you don’t know how to use solar energy at home, read this article and discover the 2 main ways of using solar energy.

How to use solar energy at home: 2 ways

Solar electricity production

In order to explain how solar electricity production works, we shall explain what are the main components of a solar panel. Although there are some specificities concerning each installation, every solar system work in a similar way.

First, the photovoltaic panels capture the sunlight and create a direct electric current (DC).. An inverter then converts the direct current into alternating current (AC)for use in homes or businesses. The solar system has a two-way electricity meter that records the production of energy and evaluates if there is need to use other sources of external energy from the national electricity grid. The energy produced can be stored in a battery for later use as well.

Living in a city, there are some limitations such as where install a solar panel, principally if you live in an apartment. Other than traditional solar rooftops, some people choose to put the panels on the exterior walls of their building in a way that allows them to take maximum advantage of the Sun exposure.

Solar water heating

Solar water heaters are a renewable solution for those who choose to use solar energy for their plumbing system. If you pay your own bills, you probably know how much electricity is spent on heating water for your daily routines like a simple bath. You can cut your expenses by investing in a solar water heater. Like solar panels, the initial investment might be a little expensive, but the savings will surely compensate.

There are two types of solar water heaters in the market: passive and active. The main difference between them is the method used to heat water. In the active water heater system, the container preheats the water.

A solar panel is sometimes also connected to a traditional gas or electric heater in order to regulate the liquid’s temperature.

On the other hand, the active water heating system doesn’t have the connection to any other kind of heater. Before the water flows through your tap, it is “filtrated” by the solar panel that heats the liquid. If the first system is better for homes, the active water heating is more suitable for those who have private swimming pools.
