Solar panels are a great "green" addition to any home. That said, the roof underneath the solar panels is just as important. With an asphalt roof, the homeowner is going to be removing the solar panels to replace the asphalt roof long before the solar (PV) needs to be replaced. This wise choice would be to install a lifetime aluminum energy star rated roof and attachthe PV solar to the new metal roof. When the PV needs to be replaced or removed the roof will still be in service. In fact will last for many years beyond the life of the solar panels. On a different note, if you decide to install solar be sure you have a landing area for the snow slides coming off the panels. It is a little known problem that is just coming to light by the industry. Snow slides coming off a roof with solar can cause significant damage or injury. Be sure to address this issue with your solar contractor.

While adding PV panels is a noble endeavor, it is unlikely to produce more than about one third of your annual electrical requirements.  Less than that, if you have air conditioning, even in a newly built, energy efficient home.  The financial savings, though, will continue to climb over time, as more dams and coal power are elliminated, and the cost of generation climbs steeply.  The payback time will shorten, and the lifecycle of the panels will net a return toward the rest of the power you use.

Here's the scoop:

It all depends on your usage and how much room you have for panels, but we routinely knock out 100% of our clients' electricity bills.

However, the system will almost certainly be what we call "grid-tied", meaning that you will still be connected to your utility. This is important as solar tends not to work so well at night. So what will happen is you will produce more during the day than you need, pouring the extra power back into your utility and running up a credit, essentially using the utility like a "power bank". You then pull power from the "bank" at night. Note that this may happen on a daily level, or over the year, with your system producing a net surplus some months, and using that surplus in months where production is less.

The upshot is that, while your net consumption of power from your utility over the year may be zero (or close to zero), you will still "need...power from your local power company" in order to compensate for variances in solar production.

In addition, different financing methods may work best with different production goals, due to the way your utility prices the power you use, i.e. in a tier structure, versus how your solar is financed. This is a bit more complicated, but I'd be happy to walk you through it if you want to give me a call - John Cook, (888) 603-4255.

I hope that wasn't too technical or convoluted, but I wanted to make sure you had the facts. Good luck!

We suggest Simonton Vinyl Replacement windows to all our customers. They are very energy efficient and work flawlessly. I will show a customer a lot of the times how I can open the window with ease with my pinky finger. It's hard to say how much you will save on your energy bill. There are a lot of factors involved. If you currently have a well insulated home and low energy bill you probably won't save that much. If your home isn't that well insulated and large energy bills it will show up more there. I use the example of my grandfather alot. He replaced his windows with Simonton about 10-15 years ago. They have a small 3 bedroom ranch and were having utility bills of $3-400 a month. They replaced the windows and the bill came down to $100 a month. If you are having a hard time keeping your rooms cool in the summer and warm in the winter, you will see a drastic difference in your comfort level along with the power bill. Another reason we offer Simonton is the affordability. We typically install a 5050 replacement window turnkey around $400 per window. Of course there are reasons this can go up, but typical install is on average this price. I would suggest going to simonton.com and searching for an experienced installer in your area. Hope this helps! Good luck with your search. 

All of the answers given were great options. There are many, many ways to improve a home's energy efficiency. As we are a siding and window company, my focus will be on those areas. Windows are a huge energy loss/gain. Did you know that windows and doors account for approximately 50% of your heating/cooling loss? Air leaks around a window or door due to a crack of 1/16" of an inch is like having a hole in your wall the size of a brick. In the average home, that is equal to about 15 bricks. Consider how large that "hole" is in your home. The glass package is the most important thing to consider when replacing windows. Most folks just look at the cost of the window and install, and some smoke and mirrors some companies like to drag on about. A smart homeowner knows what Low-E is, what a good U-Factor rating is, whether or not it's single, double or triple pane glass, etc. etc. Same features apply to most doors. Lastly, siding is another area where a homeowner can save money. Check into insulated siding. Check to see what kind of underlayment is being applied to your home. Many companies don't even put a housewrap on to save cost and the average homeowner never knows. Make sure you only hire someone who is appropriately licensed and insured. Ask to see those documents. Hope this helps folks looking to replace siding, windows or doors! Happy remodeling!

With anything like this, I hate to be the first especially with this manufacturer. They brought out the Nest smoke detector and it get recalled.  I would rather wait  and watch the press and blogs and when the dust clears and all is good then starting specifiing them.

Spray foam insulation is by far the best for an attic.  It is sprayed in the rafters areas and basically seals off the entire attic and stops the heat as soon as it enters from the roof.  It can be very expensive though compared to regular fiberglass insulation or blow in insulation. 

We've used Kohler generators for years and had great experiences both from the sales staff and the service staff. They have great options now for the transfer switches with options for locking out specific loads without having to go to the expense of a separate generator panel. The specific size/design/installation is best left to your professional electrician- Good luck!

If you can amortize it into the long term loan on the home, it is a 100% no brainer.

Yes!!

Alex, the region you are in is crucial and consider the cost vs time of recapitization

GAVIGAN HOMES// Go 15 Seer minimum and check your duct work. Metal boxes instead of fiber board are huge mold mitigation upgrades. Get a blower door test 

From what I've found online it does not qualify unfortuantly.

"The credit applies to improvements such as adding insulation, energy efficient exterior windows and energy-efficient heating and air conditioning systems."
