Which "solution" will be the most powerful for you? Check the questionnaires.
If the South side of your roof gets
plenty of sun, you could harvest
"free" energy - with solar panels.
Warning:
​
The Chinese cornered the solar market partly by using forced labor in Communist concentration camps (of the minority Uyghur people).
Consequently, (2021) Congress passed the Uyghur Forced Labor Prevention Act
which was intended to prevent such products from reaching the USA, and to help competitor companies in the "free-world". ​​​​​

Getting a loan to pay for installation is usually better than leasing: leasing-vs-buying

A credit union may have a better loan than a bank or contractor. Search: credit unions near me​

When shopping, compare the warranties of the panels and inverters. Micro-inverters are best if any of the panels are occasionally in shade.

SolarReviews and EcoWatch rate top solar companies, although Ethical Consumer magazine gives none of them a good score (for reasons mentioned above). Sharp might be the best of the not-so-good, as it "scored reasonably well in many ... categories".

​​How many panels to put up will depend on your budget, rooftop space, and sunlight access. Our costs came to $4,000 for 5 panels (a small project) several years ago, and we got the cheaper, less efficient, polycrystalline panels. "After solar incentives, [costs range from] $10,000 to $30,000 for an average American household."
30% of the cost of the installation could be offset with a federal tax credit. However,
the Investment Tax Credit expires 12/31/25! See the Rebates and Tax Credits page.
Also consider that solar panels "will likely increase your home’s value".

It often makes sense to get a battery storage system installed at the same time as the rooftop solar system.

​
When there's an electrical blackout, you will not be able to use (grid-tied) electricity from your roof, UNLESS
​
- you have an Secure Power Supply (also called a battery backup system) and
- you can (temporarily) disconnect from the utility grid
