What is solar energy with TESLA? What’s the price in Barcelona?<\/p>\n

What is an Off-Grid house? What is a self-sufficient house? What’s the price?<\/p>\n

In this post we explain the basic notions of Solar Energy and TESLA batteries price in Barcelona.
\nIn case you still don’t know us, let us introduce ourselves.
\nWe are ERA architects<\/a>, one of the young, committed and creative architecture studios in Barcelona<\/a>.<\/p>\n

What is an Off-Grid House?<\/strong><\/p>\n

A disconnected house is a house that does not need to connect to the electricity grid because it generates its own energy.
\nOff-Grid House is called to those homes that are self-sufficient of electricity, water (usually harvesting rainwater) and manage their own waste (usually with a septic tank and natural drainage).<\/p>\n

 <\/p>\n

Is self-sufficiency a real thing?<\/strong><\/p>\n

Spain is a country with Sunny days and therefore we do not lack the basic source of energy.
\nHowever, saving that energy still remains to constant evolution.
\nTESLA has made a long way to store domestic energy. Their batteries are the best option on the market to accumulate the energy that is captured from the Sun.
\nEven so, these batteries have room for improvement in terms of electrical independence.
\nSurely you may wonder: how many days of electricity do these batteries give me? If it is cloudy for 5 days in a row, will I continue with electricity?<\/p>\n

Before answering this question you need to know that each house and family has a different electricity consumption. It is not the same a family of 2 who go to sleep soon and have no washing machine or refrigerator than a family of 5 who use the oven every day to cook.<\/p>\n

Thus, depending on the electrical consumption of each family, these batteries can give an electric independence of between 1 and 4 days.
\nIt is also worth specifying that on cloudy days there is also solar gain but to a much lesser extent.<\/p>\n

Things to keep in mind<\/strong><\/p>\n

To know how much energy you need to generate, you must first calculate the energy consumption your family uses according to their routines and habits. This means calculating the consumption of:<\/p>\n
