When you can't afford a full system, instead start with a solar water heating system. Water heaters make up a large portion of the energy that a home consumes during the year. Your costs are going to be lower upon installation of your solar water heating system.
I explain how much this system cost and I go over the site plan and electrical diagram in this link https://youtube.com/watch?v=TFwdY0wiBGA Keep in mind …
Track numbers when getting solar panels for the home. Solar panels might not be a good option if you cannot count on optimal exposure to sun rays in your area or if you use more power than a regular solar energy system can generate. You need to do all your homework, so you know if this type of energy is really going to save you money.
If you're trying to design your new house, think about putting in a bunch of big windows on the home's south side so that during the winter you can get a lot of sun. Make sure you have methods in place to keep excess heat out during the warmer summer months. For more help, consult a contractor who specializes in solar energy.
