Last winter, we kept our house at 60 degrees and our electric bill was STILL $280. I’ve been interested in solar for a long time, but on the long list of house projects (especially when you’re restoring a 200 year old house on the historic registry) some are more pressing than others.

But with a few of those major projects wrapping up, and a daunting bill before me, I figured now was the time for a quick google search on solar panels, and let me tell you….. It can be very overwhelming.

Figuring out the rules (cough, cough, historic society), incentives or rebates if applicable, how much it would cost, how much we could save, etc. felt a little like a part-time job. But, one website made it really easy to compare things, and I am happy to be partnering with Aurora Solar to share that site with you.

Because I think you should be able to easily run the numbers on your house without a lot of hassle!

This post is sponsored by Aurora Solar, but all thoughts and opinions are my own.

If you’ve ever gotten a solar quote, there’s a good chance that Aurora Solar was involved. Aurora was founded in 2013 after its co-founders spent seven months trying to design a solar energy system using a patchwork of different tools.

Afterall, designing a solar system shouldn’t be harder than actually installing one. So they built software specifically for solar professionals. Today, more than 7,000 solar organizations use Aurora, and more than 20 million solar projects have been designed using the platform. They are also the largest solar software provider in the world. Their software is used by roughly 80% of the top 75 residential solar companies in the U.S.

All of this tech has been primarily used by professional installers to map your roof and then create a proposal, but now Aurora is offering this tech to us to help compare quotes.

So instead of having to call a bunch of different installers, I could use the Aurora Solar Marketplace to understand my solar potential, compare estimates, understand my possible savings, look into battery storage and other home electrification incentives, and map out different financing options.

1. know how much electricity the system will actually produce

Before you even get into the price, make sure you understand what you’re actually being quoted.

Two solar systems can have very different prices because they may not be the same size or produce the same amount of electricity. A cheaper system might simply have fewer panels and offset less of your electric bill.

With Aurora, you can compare solar estimates and see the system size, energy production, and how much electricity the system should offset.

You can also upload your utility bill to get a solar estimate based more closely on your actual energy usage, to make the quote accurate for you instead of a ‘generic household’.

2. understand the solar payback period

Aurora calculates things like payback period and lifetime savings, which makes it much easier to understand the long-term finances.

The solar payback period is basically how long it takes for your estimated savings to make up for what you spent on the system, and this is the number that surprised me most!

One estimate had a payback period of around 7 years, and another was closer to 11 years! Over 25 years, two of the estimates I looked at had almost a $13,000 difference in projected savings.

Of course, these are still projections as electricity rates can change (HELLO 2026) but when you’re trying to compare two options for the same house, knowing that one is projected to pay for itself four years sooner is pretty useful information.

3. look beyond the monthly payment

Depending on the installer, you may be looking at a cash purchase, solar loan, lease, or power purchase agreement.

But thankfully with Aurora you can compare the different financing options side-by-side which makes it a lot easier to see the trade-offs. One option may have a lower upfront cost, another may have a lower monthly payment, and another may give you better long-term savings.

4. find out which solar incentives actually apply to you

The minute you start Googling solar, you can find federal incentives, state incentives, utility programs, rebates, net metering, and a whole bunch of information that may or may not even apply to where you live.

And some of the articles ranking at the top of Google are several years old! (RIP to the federal incentives canceled at the end of 2025.) But, Aurora can account for solar incentives when calculating the cost and savings of a system, including state, local, and utility-specific programs.

I would still double check any incentive or tax benefit you’re planning to use before signing a contract, especially because programs and eligibility can change, but having all the relevant information in the same place makes the research process much less overwhelming.

5. research the installer, equipment, and warranties

Aurora lets you compare solar installers based on things like reviews, reputation, pricing, and financing options, which I think is just as important as the actual quote.

I’d also look closely at what equipment is included. What panels are they using? What kind of inverter? How long are the equipment warranties? Is there also a workmanship warranty from the installer? Who handles repairs if something goes wrong five or ten years from now?

And, I know I’ve said it a million times, but it’s nice to see it side-by-side without having to fill out a bunch of forms and be hounded on the phone just to get an idea of what solar may look like.

How to Compare Solar Quotes: What to Look For Before You Choose

Buyers contracted nearly 30 million tons of durable carbon removal in 2025, more than triple the 2024 total, according to CDR.fyi data reported by Heatmap. About 90% of those purchases came from a single company, Microsoft, and suppliers delivered only about 450,000 tons during the year. That is a sliver of the six to 10 billion tons of removal a year that climate scenarios suggest the world will need by 2050. The technology to pull carbon out of the air works, but the customers needed to scale it remain scarce.

Our guest today, David Babson, is executive vice president of the Energy, Climate, and Nature domain at the XPRIZE Foundation. He calls the slow progress a market failure, because the technology is progressing faster than it is being adopted. Babson previously led MIT’s Climate Grand Challenges initiative and was a program director at the U.S. Department of Energy’s ARPA-E. His portfolio includes XPRIZE Carbon Removal, which drew 1,334 teams and whose participants have raised more than $3.3 billion. In April 2025, Mati Carbon won its $50 million grand prize for spreading crushed basalt on smallholder farms in India, where the rock locks away carbon dioxide. “If people could make money taking carbon out of the air and putting it underground, as opposed to only being able to make money taking it from underground and putting it in the air, we would be in a better place,” Babson says. Mati is weathering the slump in part because its rock dust also improves soil health and crop yields, giving farmers a reason to participate that does
