How much do solar panels cost for an average home in the Public Service Company of New Mexico (PNM) service area?
The cost of installing solar panels in New Mexico varies with the brand of solar panels and inverters you choose, the installation company you choose to install them, the relative ease or difficulty of installing solar panels on your home, and of course the amount of solar panels you need to cover your electricity usage.
If we enter the details of a customer with an average PNM power bill into the Solar Estimate solar power calculator it shows that a 8.93 kW solar power system is needed to 100% offset usage, in kWh terms. (What is a kilowatt hour?)
The average cost of a solar system in the PNM service area, based on current local solar offers from solar companies is $2.65 per watt. This makes the cost of a standard 8.93 kW residential solar system $23,665 before the state and federal tax credits and $15,761 after tax credits are received. But don't stress, these days there are a myriad of competitive zero down solar finance options available.

Are solar panels worth it for Public Service Company of New Mexico (PNM) electric customers?
There are three main reasons why installing solar panels for homes is so popular in New Mexico and specifically in the Public Service Company of New Mexico (PNM) territory. These reasons are:
- PNM customers can still take advantage of the 26% federal solar tax credit to install solar panels until it reduces at the end of 2020.
- PNM still offers a price close to retail power prices giving good value for excess solar power customers export to the grid (what is net metering and what is a feed in tariff); and
- New Mexico, and the Public Service Company of New Mexico (PNM) service territory within it, have a lot of sunny days meaning solar panels produce a lot of electricity.
How much will solar panels save the average Public Service Company of New Mexico (PNM) residential customer?
The savings will vary depending on how much your power bill is now, the specific PNM rate plan you are on and how suitable your roof is for maximum solar generation.
If I enter the details again for Public Service Company of New Mexico (PNM) customers with an average power bill for a single family home into the best online solar panels calculator it tells me that I need a 8.93kW solar system that will produce 14,343 kWh's per year and that this system will likely return the owner a $86,269 profit even after repaying the capital over 25 years.
This is pretty amazing when you consider that you can get a zero down loan, contribute none of your own capital and still make such a big profit. When you compare this with the return on other home improvement projects this is seriously good. What's more this profit doesn't even include any capital value that solar panels may add to your home. This is just the utility bill savings.
How much will installing solar save a Public Service Company of New Mexico (PNM) customer in the first month?
Monthly savings year one $86
The graph above shows the savings for this customer in the first month that their solar system is live. It assumes that the system is purchased via a 100% loan product.
One of the common reasons why people have been slow to install solar panels, despite the excellent financial return they can provide, is that often the first months savings may not appear to be enough to motivate them to go through the process of buying solar. Let's face it, we are all busy and we are only going to get off our backside and do a project where we can get a pretty big pay off for doing so.
However, it is important to realize that solar savings grow over time as utility prices increase. As can be seen in the graph below, the solar saving are quite considerable when totalled over the 25 year life of the system.
The overall lifetime profit will be even more with a cash purchase of the same system. The difference being that we have included the cost of interest in the lifetime savings summary below.

How much roof space is needed for solar panels for the average customer?
The estimated south facing roof space required for the solar system referred to above is 595 square feet. Of course, your home is unlikely to be exactly the same as an average home. You may use more or less power than the household we have used in our example and also the characteristics of your roof may be such that solar power production from panels installed on your roof may be less than the electricity production from solar panels installed on a perfect, south-facing, unshaded roof.

How many solar panels are needed to power a house in New Mexico?
One of the first questions people ask when considering solar is how many solar panels do I need? The answer to this question depends on the power usage of the home, the location of the home and the suitability of the roof for solar electricity production. Some people are lucky enough to have a perfect south-facing, unshaded roof, but for many of us it is necessary to use parts of our roof that do not produce optimal generation. However, it is often possible to still get a very good return on investment from installing solar panels even if the annual generation from the panels on your roof is 10-15% less than optimal because your best available roof space is facing east or west.

Why do solar savings for a typical Public Service Company of New Mexico (PNM) customer add up to so much over the life of a system?
Solar savings over the life of a solar panel system add up to much more than what most people think they will because of the enormous power of compounding increases in electricity prices over time. Even with modest annual increases of 3-4% per year over the 25 year life of a solar system utility electricity prices will grow by 240% over current Public Service Company of New Mexico (PNM) electricity prices.
|System Size||8.93 kW|
The above cash flow projection assumes a solar system that offsets 100% of power usage, a finance rate of 3.99%, a financing period of 20 years, a minimum utility charge equivalent to 10% of bill without solar, and a utility cost inflation rate of 4.5% p.a.
What is the average payback period for residential solar panels for an Public Service Company of New Mexico (PNM) customer?
The payback period for Public Service Company of New Mexico (PNM) customers installing solar panels on their homes depends on their power usage prior to installing solar, the finance method they choose to pay for their solar system, the size of system they install, the orientation and tilt of their roof and any shading that may affect output.
What we have done above is copy an extract from our PNM solar panel savings calculator which shows the payback period for a typical PNM customer. You can visit this calculator above and enter your own current power bill to see your solar savings and your likely payback period. You'll note that for customers with larger monthly power bills the payback time is usually slightly shorter because the cost of solar systems per watt usually reduces as the system size increases.

To do this they need to know your power usage patterns. This will allow you to come up with the amount of solar panels you would ideally want to make your power bill zero. See below for ways that you can get hold of your power usage data either for your own analysis or to share with a solar company that you wish to have quote your home.
Once you determine the right amount of solar panels you then need to measure your roof to see how many panels will actually fit on your roof. Most solar companies can measure roof spaces online using tools that are similar to Google Maps (but are more accurate) such as www.nearmap.com.
The www.solar-estimate.org website is the leading solar marketplace in America and allows you to both do an accurate online estimate of your needs yourself and, if you wish, request quotes from solar companies through one interface.
