Alex,  

Solar panels are a great long term solution for energy savings. The average time frame for recovering the initial cost of the panels and installation is about 5 years, so if you are planning on living in the home for longer than 5 years, you will begin to see a return on your investment around year 6 and beyond. Also a big bonus is that tax credits are available to homeowners on both the state and federal level for solar currently!

Hope this helps! Good luck with your new home =)

When it comes to energy efficiency, adding insulation is the most affordable upgrade that can be done to a 2-story home. With good insulation, there will be an immediate return on the money spent. A high performance energy efficient heating system is also very important. Energy efficient heating and good insulation work hand in hand by paying the homeowner back hundreds of dollars a year, along with the home being much more comfortable to live in. Lifetime aluminum metal roofing should rank very high on the priority list for an energy efficient home; certainly among the top three upgrades. The product itself is made from a very high percentage of post consumer aluminum. It is also considered to be among the most long lasting sustainable roofs that can be put on a home.There are aluminum roofs that are well over 100 years old in the USA. These roofs have very high reflectivity, which equates to high energy savings during the summer months or in the south where air conditioning is needed. These energy star rated roofs can save as much as 30% on energy as it relates to cooling costs. With proper insulation, energy efficient heating, and metal roofing, the home will have optimum energy efficiency and continue to remain at the most comfortable temperature based on the given seasons.

The first thing to reduce energy is to see where it is being wasted.

 An energy audit with blower door test and infared camera is the best place to start. 

 The list of upgrades range from adding insulation, to replacing HVAC systems and everything in beteen, such as new windows and doors to installing smart theromstats. But because each home is different and has different needs the only way to be sure your upgrades are right for your home is to start with an energy audit.

Get with a local solar company and have them look at your plans.  You may be building a home that cannot work with solar due to your roof pitch, orientation or shade.  Let them give you a site assessment and run the financials based on your available incentives.  You can look them up here:  http://dsireusa.org/

Solar Panels are increasing in energy generation and energy storage is getting better and better.  You definitely need to make sure that your dwelling is positioned on the property to maximize benefits.  While it is way down the road, make sure to investigate the implications of what happens when the day comes to replace your shingles.  I would make sure you also have adequate insurance in the event the panels are damaged by hail, trees etc. and that you have a comprehensive maintenance program in place should you elect to have panels installed.  You may want to check with your local building code authority and see if you are able to have solar panels on your property other than on the roof if you have enough space.  Just like the VCR, solar panels are coming down in cost and going up in efficiency, so you may want to wait.  If you could have many less panels in the near future, that produce more output, that may be the best choice. Here is a link of many residential applications https://images.search.yahoo.com/search/images;_ylt=A0LEVzpL309ThhkA45xXNyoA;_ylu=X3oDMTB0YXQwZXBpBHNlYwNzYwRjb2xvA2JmMQR2dGlkA1ZJUDQxNl8x?_adv_prop=image&fr=yfp-t-745-s&sz=all&va=solar+panels+homes

The shape of your roof will definitely have an impact, but generally speaking, solar pays for itself in spades.

The other thing to consider is that solar is ideally tailored to your personal electricity requirements, which you won't know for sure until you've been in the house a few months (a year, for a complete picture). You're probably safe installing a smaller system (which is what you usually find on new construction), but you'll likely find it won't cover everything. If you decide to go forward now, just make sure the system is expandable down the line; this is one of many reasons you'll want microinverters as opposed to a string inverter.

Good luck!
