How much do solar panels cost in West Hartford, CT?

The average cost per watt of residential solar in Connecticut is $3/watt. For comparison, the national average is $3.70/watt.

Cost per watt is the total installed cost of a system, including taxes, divided by the size of the system in watts (DC). It includes the cost of hardware plus installation costs. Cost per watt is always the gross cost, before incentives. This means, at a minimum, you can take 30% off the price of the system in 2019 because of federal tax incentives.

The cost of a solar panel system for your house in West Hartford will depend on how much electricity you want to generate, which affects the size of the system you’ll need. The following is an example price estimate for a home solar panel system in West Hartford, with an electricity generation estimate based on the local climate and the following assumptions:

• 690 kWh is the amount of electricity that the average Connecticut home uses every month.
• 5.93 kilowatts is the size of the system you’ll need to generate 100% of this electricity from solar panels.
• 15 to 23 panels is what that translates to (depending on panel efficiency, which commonly ranges from 260 watts to 400 watts)
• Panels oriented due south and mounted on a shade-free roof at a 30° angle.

Can you save money with solar panels in West Hartford, CT?

Every year, that hypothetical West Hartford home solar system described above would produce about $1,700 worth of electricity. This is based on the Connecticut state average price of electricity of $0.20/kWh and the average local climate.

But that’s just a home with average electricity usage. You might need more or fewer solar panels, depending on how much electricity you want to generate. Also, shade matters a lot. If you have trees or buildings throwing shadows on your roof, that could reduce your solar production by a lot.

Houses in West Hartford with solar panels

In West Hartford, our data shows that there are at least 306 houses with solar photovoltaic panels installed. This means that a lot of neighbors in your city are interested in solar, and have already made the leap. Added up, the total generating capacity of all these home solar systems equals 1,896 kilowatts. That’s a lot of clean energy being generated by your neighbors.

If you’re on the fence about going solar and trying to research whether solar is viable in the West Hartford area, this is good news. It means many of your neighbors have made the calculation and decided that solar is a smart move for them in the long term. Next time you’re driving or walking around, take a look at the roofs in your neighborhood. You might find a surprising number of solar panels. Try talking to your neighbors with solar, and see how it’s worked out for them.

Solar panels directly turn sunlight into electricity, so the more sunlight you have, the more power that a solar panel system will generate. However, one misconception is that solar panels only work in very sunny climates. While it’s true that you will generate more electricity in a sunny state like Arizona, you might be surprised to learn that solar can generate plenty of electricity in most places in the United States - even cloudier places like New England or the Northwest.

West Hartford solar energy potential

To make a fair comparison of how much sunlight different cities get, we use a measurement called Direct Normal Irradiance (DNI). It takes into account the position of the sun in the sky throughout the year, cloud cover, airborne particulates, precipitation, and other climate variables.

The DNI for West Hartford is 4.54, which means that it has a good amount of sunshine - about average for the United States.


Averaged over the full year, a West Hartford home solar panel system will be generate a lot of solar electricity, although expect diminished production in the winter.

In the continental United States, DNI ranges from about 3.0 to 8.5 kWh/m2/day. In the most northern parts of Alaska, the DNI reaches a low of 0.5.

A higher DNI is better, but even if your city is average or even below average for the US, it’s still possible for solar panels to generate plenty of power. For example, solar is very popular in Germany, where the DNI is only around 2.5.

This DNI data comes from GEOS geostationary satellite data and NREL climate models.

The graph below estimates how much a 6 kilowatt south-facing solar panel system would generate in West Hartford.

Power Generation by Month (kWh)

The seasonal variation in solar electricity production in West Hartford is quite small. In the peak month, a home photovoltaic system would produce 197% more electricity than in the lowest production month in winter. This is less of a variation than in many other climates in the US, and it means that even in the winter, you might not need to draw much electricity from the grid, and have less excess electricity to send into the grid in summer.

Solar panel lease companies in West Hartford

If you’re thinking about going with a solar lease or PPA, you should first read our guide to solar financing to make sure that you understand the pros and cons of a lease or PPA versus purchasing a system outright. In most cases, you will come out on top by buying your solar panels, even if that means taking out a loan.

That said, leases/PPAs continue to be popular, and they can be a good choice in some cases. There are several national solar installers that offer leases/PPAs, but not all of them operate in every state. Here’s a breakdown of some of the major solar installers that offer these types of contracts, and whether they operate in your state:

Average Connecticut electricity prices

Right now in Connecticut, the average price of residential electricity is about 20.29 cents per kilowatt hour. In comparison, the average price of electricity in the United States is about 13.34 cents per kWh.

This means that your price of electricity is about 52% higher than the US average, which makes your electricity rates very high compared to the rest of the nation.

With high electricity prices like this, it makes a lot of sense to consider whether solar panels are a good choice for your home. With the cost of solar hardware dropping all the time, if you have a suitable roof or yard for solar, it’s very likely that solar electricity will be cheaper than the high utility rates in your state.

Regardless of what your electricity prices are, by adding solar panels to your house and generating your own electricity, you’re locking in your cost of electricity for as long as your system is working, which will protect you from future rate increases by your utility. Given that many panels come with 25 year warranties, this is an investment that can last a long time.

Keep in mind that the price of electricity varies by utility, sometimes by a lot. The table below lists the average price of electricity for utilities in Connecticut state. For current rates, check with your utility.

Historical Connecticut electricity prices, 2008 to 2017

The average price of residential electricity in Connecticut, over the past ten years, is 19.31 cents per Kilowatt hour. This is 60% more than than the US average price of 12.07 cents per kWh. Because your state historically has had high electricity prices, there’s a good chance that prices will continue to be high in the future. This is a good argument for going solar.

Why is this important to know? Depending on the size of your system, owning home solar reduces or eliminates the effect of electricity price increases.

One of the big financial advantages of going solar is that you basically lock in your price of electricity for the next 20 to 30 years (because most solar panels come with 25 year power warranties). When you look at the graphs above and see the historical trend of electricity prices in the United States, you’ll notice that prices steadily increase over time. While prices from your utility may bounce up and down, the cost of electricity eventually increases over time. Going solar will protect you from those increases.

Environmental report for Connecticut electricity

Depending on the type of fuel they use, power plants produce differing amounts of air pollution. This is measured as units of pollution per megawatt hour (mWh) of electricity.

For every mWh of electricity generated, Connecticut power plants produce on average:

  • 228 kilograms of CO2, which is 50% less than the US average of 459 kg.
  • 19 grams of SO2, which is 95% less than the US average of 411 g.
  • 173 grams of NOx, which is 54% less than the US average of 373 g.

In the power generation estimate listed above, The Solar Nerd calculator determined that an unshaded, south-facing 6 kilowatt PV system would generate about 8,377 kWh in an average year.

This means that putting a 6 kW solar panel system on your house would prevent 1,910 kilograms of CO2, 159 grams of SO2, and 1,449 grams of NOx from being emitted into the atmosphere.

The carbon offset of these solar panels would be about equivalent to planting 111 trees every year! (One deciduous tree left to grow for 10 years offsets 17.2 kg of CO2, according to the EPA.)

CT state average electricity emissions
CO2 is carbon dioxide and is a primary greenhouse gas.
SO2 is sulphur dioxide. It damages the human respiratory system and contributes to acid rain.
NOx refers to nitrogen oxides, which contribute to smog, acid rain, and lung damage.
