Ann Arbor Energy Efficient Mortgage Project

For about 15 years I’ve been hearing about energy efficient mortgages. That is mortgages that are set up to encourage energy efficient improvements or designs.

Well it appears that we should utilize one of these for our Ann Arbor solar project, but even though I’m a mortgage expert I don’t know anyone personally who has experience with these.

So, a new research project. Here are the links I’ve found so far:

This is from 2009 and is fairly useful: It mentions a $8,000 cap for FHA but also mentions an additional $4,000 for weatherization.

Federal Citizens Information Center in Pueblo:


Notes on Fannie Mae Program:

Residential Energy Services Network information on mortages:

FHA mortgage letters, guidelines, and example:

Fannie Mae Energy Addendum Form:

Not terribly useful article on FHA EEMs:

FHA pages:

Judging from this it looks like FHA limits the improvement cost to 5% of the median area price. ($165,000 in Ann Arbor), this means about $8,000 which isn’t going to buy many solar cells!

This site discusses the Energy Star mortgage which is a pilot program in a couple states. (not Michigan)

Good Fannie Mae presentation from 2003:

FHA site including their EEM letters:

FHA fact sheet that says if homeowner has the skills that lender may allow homeowner to provide the labor: (There are a lot of good EEM documents on this site. Search for Energy Efficient Mortgage.

Here are some interesting energy saving window panels that can take a single pain of glass up to energy star standards with just an interior storm window:

What are home solar power panels? The primary function of a solar panel is to transform sunlight into usable electricity. This effect is a physical manifestation of the photovoltaic effect. Solar panels are made up of solar cells that are gathered together within a frame. Each solar cell has the capability to convert the sunlight into useful electricity. However, the conversion rate of each cell is somewhat limited when measured in total wattage output. Basically, each cell only produces an amount of electricity equivalent to 1 to 2 Watts. Therefore a very large number of solar cells need to be integrated into each solar panel, and usually a significant number of panels are connected in order to form a so called solar panel array. This procedure is necessary to produce a usable quantity of solar power for a complete home.

This joining of solar cells collectively in order to establish higher power is an inherent advantage of the solar cell system. It follows that when you require additional power for personal consumption, you only have to add more panels.

There are several types of solar power panel, which have different power generating characteristics ad features dependent upon the material from which they are made. They can be made up of either thin-film, monocrystalline, or polycrystalline modules. The Thin-film solar cell consists of alloys (amorphous-silicon) which are stored in thin layers deposited on a substrate. This means it can be quite supple (dependent on the substrate used) and is therefore more easily applicable in certain environments.

Monocrystalline, on the other hand, is created from one silicon crystal rod and can be considered as having a rigid structure. The silicon rod is cut into thin wafers in order to provide the base within which solar cells are formed. Polycrystalline solar cells are processed from numerous silicon crystals that are heated together, and then cooled in molds to form ingots of silicon. The ingot is then cut into wafers and processed as before in order to produce solar cells.

The efficiency of a home solar power panel is measured by the ratio of the output and input power. Generally solar panels return an efficiency range of from approximately 10 percent to about 19 percent. As might be expected, the higher the efficiency rating obtained, the more likely the cost of each panel will also be higher. When planning a new installation therefore, it is necessary to consider initial installation costs against better long term efficiency savings in order to make the right choice for you.

Determining the right solar panels therefore requires a knowledge of some specific parameters. These parameters will help you decide which solar panel to use in your application. Three important measurements to be aware of include ‘efficiency’, ‘rated power at STC’, and ‘rated power per square foot’. ‘Efficiency’ is the ratio of the output power of the solar panel to the input power of the sunlight reaching it. ‘Rated power at STC’ measures the total output in watts from the panel under Standard Test Conditions. ‘Rated power per square foot’ is the power output of the solar panel at Standard Test Conditions per square foot of the panel’s surface area.

Finally, modern home solar power panel designs maximize the generation of electricity from solar energy and are now a very viable option if you wish to harness this form of ‘renewable’ energy to meet your personal home consumption.
