Do you know how to answer the question ” how much solar do I need to power a 2000 square ft home”? Where would you start exactly? A better question is what are the energy bills by month for this home right now. If you go back one year you can get a pretty good feel for what the energy usage has been so far.
This is a start but really how energy efficient is this home? Does the family leave the lights on everyday and night and run the hvac to it’s limits? You need to know the level of energy efficiency not just of the home but the energy habits of the people that live there.
Adding a huge bank of solar modules and battery backup is not just expensive but it unless energy management is practiced it will soon not be enough to power the home. Answering this question requires the home owner to provide a lot more details and about the house and inhabitants.
Once you have established these details you can start to work to determine the right amount of solar power. What is also important is the expectation of the inhabitants. Do they expect to be ” off grid” or just to lower their energy bills by x percentage? All good questions right?
Another consideration is whether they expect to charge any electric vehicles. Solar is great for this and makes the whole system clean from the beginning. Check out the video and see if you can answer How Much Solar Do I need?
